Garden Solutions - August 2018


            August………besides vacations, other activities that will pull you away from your list of gardening duties are fairs, festivals, family outings, and back to school preparations.  It really is a good thing that August is a slow month for working in your landscape.
            Your main tasks for this month begin with the letter W.  Weeding and watering.  Both tasks are pretty self-explanatory.  If you let weeds get ahead of you and they go to seed, you are going to have hundreds more to deal with this fall and next spring.   When using herbicides be sure to read and follow all label directions thoroughly.  They are written for your protection.  Generally, it is best to pull weeds that are growing in and immediately around your desirable plants, and spray those that are “in the open”. 
            As far as watering goes, it has been an extremely tough moisture year, so slow deep watering at the base of desirable trees and shrubs on a weekly basis is very important. Try to eliminate drought stress on your plants. Our water table is very low.  So please take care of your desirable plants with slow soaking waterings. If you have questions, do not hesitate to give us a call.
            Mowing the lawn is another task that continues in August.  Due to the usually hot and dry conditions that are the norm in August, you may be able to space your mowings further apart.  It is also beneficial to let the grass grow longer to help shade the roots. 
            If you are thinking about a new addition to your landscape this fall, now is the time to talk to your favorite landscape designer.  Your designer can discuss your needs with you, design the changes or new additions, and get you on the schedule for a fall installation.
            If you tried your hand at seasonal vegetable or square foot gardening this spring, here are a few ways you can enjoy a fall garden.  Carry Tomatoes, Peppers and Basil over in your fall garden.  Direct sow Beets, Radishes, Peas, and Spinach now where other spring crops such as Broccoli and Cauliflower have come and gone for this year.  It is best to replant nursery starts of Broccoli and Cauliflower, and not sow them from seed this time of year.
           
See you next month……….in the garden

Garden Solutions - July 2013

            Make this the NEW motto for your backyard: “Don’t GO away, GET away!” Wouldn’t it be inviting to have a getaway area in your yard? Make outdoor living, or an extension of your home outdoors, a priority this time of year. Create an outdoor living area with a reading space, a kitchen, a hammock, a family gathering spot, or a water feature for a soothing relaxation place. This action will enhance your property values and give you a great memory making area. As for the garden, there are still things that need to be done this month…

            The most important necessity this time of year, naturally, is water. Provide water in the garden, not only for the perennials, annuals, trees, and shrubs, but also for the wildlife such as birds, rabbits, squirrels, and more. There are several ways to make watering your lawn and flowerbeds easier. One would be a simple drip irrigation system to take care of your plant life. These systems can be installed with tools as simple as a scissors or knife and they are very cost effective. Timers are also available to take the guesswork out of watering for you, and the system will continue to work even when you are on vacation. Another way to make watering easier would be to have an irrigation system professionally installed.
 
            Now, do not forget to provide water for the wildlife as well as plants. Birds continue to give us enjoyment with new fledglings arriving to the feeders and birdbaths in our yard, as well as the adult birds themselves with their daily antics. Water can be supplied in the form of birdbaths, water fountains, or water garden displays. Moving water is a bigger draw for this wildlife activity than still water, and it is safer. With moving water, you do not need to worry about mosquitoes and the West Nile Virus. Any type of water feature will make your “outdoor living room” feel relaxing AND cooler! It is helpful to provide food for the birds now also. Feeding Meal Worms during this time will attract many species of birds, including (but not limited to) robins, wrens, bluebirds, cardinals, etc. This will also help the parents feed their hungry brood and insure a better survival rate.


            Now that I have spent time expressing my concern and importance for water during the summer months, let me give you some other tips for the garden…

·    Apply the chemical “Permethrin” after July 15th, to guard off grubs, fleas, ticks, etc. in the yard.

·    Keep deadheading spent annual flowers for continued bloom.

·    DON’T pinch hardy garden mums after mid-July OR you may delay blooming for fall.

·    Keep an eye out for powdery mildew and red spider mites this month in the garden. Treat with copper fungicide for mildew or Malathion insecticide respectively.

·    MULCH VOLCANOES KILL!! What this means is that you should NOT build up mulch around your trees with the tip of the volcano up on the tree trunk. In fact, it has to be just the opposite. Put the shallow ring of mulch around the tree trunk and create a saucer effect of mulch around the outside of the tree ring. This will save the tree in several ways. First, it will not kill off the trunk, and second, it will keep mowers and trimmers from disturbing the trunk bark, which can be devastating to the trees success.

·    Bearded irises can be divided at the end of the month. Discard old center sections. Replant so that the tops of the rhizomes are just above the ground level.

·    Remember to deep root water established trees and shrubs, as well, during drought conditions.

·    Prune out and destroy old fruiting canes of raspberries after harvest is complete.

·    Dig potatoes when the tops die and plant fall crops by the 15th.

·    Sweet corn is ripe when the silks turn brown.

·    For the fall garden, sow seeds of carrots, beets, turnips, winter radish, collards, kale, sweet corn and summer squash as earlier crops are harvested at the end of the month. Also, set out transplants of broccoli, cabbage and cauliflower for the fall garden.


            This is also a good time of year to consider water conservation. Here are some water conservation tips for the home and garden:

·    Water plants where it counts. Water at the roots of plants not the leaves. Focus on watering more expensive trees and shrubs.

·    Stop feeding and fertilizing. Plants and grass that have been fertilized grow faster and consume more water.

·    When you mow your grass, cut less frequently and at a higher level. Cutting the lawn short promotes growth, and growth promotes water consumption. Longer grass will shade the ground and stay healthier.

·    Cut back on household water use. Place a plastic jug filled with water inside your toilet tank. The sealed jug displaces water and allows the tank to fill up more quickly. Use a half-gallon milk jug for older toilets, and a one-liter soda bottle for newer, low-flow toilets. Keep the jug in place with a string tied around it, secured in place from the weight of the tank lid.

·    Plant drought tolerant, native plants. Many native plants are drought and disease resistant and make great additions in your gardens. Once established, these plants will need less water than hybridized varieties. Your local independent garden center can help you choose varieties that will work well for the location of your garden.

Garden Solutions - December 2012

The month of December brings the holiday season and warm thoughts of family, friends and community. I would like to say “Thank You” and wish you and yours a “Blessed Holiday Season” with all the best in the New Year!

Fall will turn into winter this month. It may not always be the most comfortable time to be planting anything in your landscape, but it is a great time for the plants. Trees and shrubs are completely dormant now, so the concept of transplant shock does not apply. 

Trimming or pruning of some of your trees and shrubs can be done now. Basically, it breaks down like this, if the tree or shrub flowers before the 1st of June don’t touch it now. If it flowers after the 1st of June, you can safely cut it now. Resist the urge to cut back everything. Most perennials benefit from adding a layer of mulch or dead leaves. If you had any fungus or disease problems in an area, go ahead and cut back the plants in that area and rake up the debris. Keep your ornamental grasses up until mid-March.

Roses: a winter “hair-cut” can be given, but don’t cut them back all the way. Some winters can be so cold that the roses could get winter die-back which would need to be removed in the spring anyway, so plan on your heaviest rose trimming in spring in early April. Apply a thick layer (10-12”) of mulch at the base of your roses now.

Plants get “chapped lips” too. Cold, dry winter winds and bright winter sun make our skin chapped and unhealthy. Those winds have a devastatingly similar effect on your plants, which are out in the winds all winter. No wonder your evergreens don’t look so great come spring. This drying effect is called desiccation. To fight desiccation, choose the right plants for windy, dry areas. Make sure to water your evergreens well through early December, before the ground freezes. Mulch your plants for winter to retain soil moisture as well as soil temperature. Use an anti-desiccant like Wilt Stop by Bonide. These products coat leaves and needles to slow down the loss of moisture.

Here are a few tips on winter houseplant care. When the heat goes on and the daylight becomes shorter. It may be necessary to move the plants to a different place in the home and to give them different treatment from that given during the summer. Flowering plants need at least half a day of direct sunlight. Cacti and many succulents require a sunny location, and crotons need direct sun to maintain the decorative color. The ideal temperatures for foliage plants are 68-70 degrees during the day and slightly lower at night. Remember, windowsill locations are much colder during the winter and plants may need to be moved to prevent them from getting chilled. The amount of water the houseplants need declines during winter, so increase the amount of time between watering.  Reduce fertilizing as well.

Some of the plants in your landscape can help you decorate for the Christmas season as you prune them for next year. Holly and Boxwood can be trimmed now with some of the cuttings used to accent wreaths or live indoor plants. Some of the growth of evergreens such as White Pine, Norway Spruce, and even some of the seed heads of ornamental grasses can be used to make a harvest wreath or basket for your front door or porch. Talk about recycling! After Christmas, you can take them to your compost bin for future fertilizer! Along with these Holiday tips, here are a few other ideas for the month:

·                     Use caution when spreading salt or calcium on ice or snow packed walks or driveways. Salt can damage lawns and plantings, calcium is much safer to use. Be sure to designate areas to for piling snow from plowing in advance to prevent damage to trees, shrubs and lawns.

·                     Continue to feed our fine feathered friends and place heated birdbaths with fresh water out for them.

Again, I wish you and your family a very Blessed Christmas season.  Let’s get to work on planning that beautiful garden scene for next year!

See you in the Garden…………..

Garden hose end with water flowing out

            August………besides vacations, other activities that will pull you away from your list of gardening duties are fairs, festivals, family outings, and back to school preparations.  It really is a good thing that August is a slow month for working in your landscape.

            Your main tasks for this month begin with the letter W.  Weeding and watering.  Both tasks are pretty self-explanatory.  However, I feel the need to explain them to some extent. It is important to stay on top of the weeds.  If you let them get ahead of you and they go to seed, you are going to have hundreds more to deal with this fall and next spring.  Spraying weeds in landscape beds with an herbicide such as Roundup is one of the easiest ways to rid of weeds.    When using herbicides be sure to read and follow all label directions thoroughly.  They are written for your protection.  Generally, it is best to pull weeds that are growing in and immediately around your desirable plants, and spray those that are “in the open”. 

            As far as watering goes, it has been an extremely tough moisture year, so slow deep watering at the base of desirable trees and shrubs on a weekly basis is very important. Try to eliminate drought stress on your plants.  Weak plants open up avenues for disease and insects to overcome.  The drought we are experiencing actually goes back to spring of 2011.  Do you remember the very wet and cool spring of 2011?  Boy, I do.  Well we went into a dry summer, than a dry fall, and then we essentially had no snow this past winter and than a very dry spring of 2012.  Our water table is very low.  So please take care of your desirable plants with slow soaking waterings.  If you have questions, do not hesitate to give us a call.

            Bugs, they really bug me, and some of them can really mess up your plants.  Before you grab that bottle of insecticide and run out and spray every bug in sight, it is important that you identify the bug that is bugging you.  Most insecticides can’t tell the difference between a beneficial insect like a honey bee and the destructive spider mite.  Therefore, it is important that you know what bug you are trying to kill and the best method to do it.  If you collect some samples of your bug to bring in to be identified, please put them in a Ziploc bag and seal it before bringing it in.  Once we ID your pest, we can tell you the best way to control it.

            Mowing the lawn is another task that continues in August.  Due to the usually hot and dry conditions that are the norm in August, you may be able to space your mowings further apart.  It is also beneficial to let the grass grow longer to help shade the roots. 

            If you are thinking about a new addition to your landscape this fall, now is the time to talk to your favorite landscape designer.  Your designer can discuss your needs with you, design the changes or new additions, and get you on the schedule for a fall installation.

            This spring if you tried your hand at seasonal vegetable or square foot gardening, here are a few ways you can enjoy a fall garden.  Carry Tomatoes, Peppers and Basil over in your fall garden.  Direct sow Beets, Radishes, Peas, and Spinach now where other spring crops such as Broccoli and Cauliflower have come and gone for this year.  It is best to replant nursery starts of Broccoli and Cauliflower, and not sow them from seed this time of year.

            Last but not least, take care of yourself.  In the heat that is referred to as August, it is easy to over exert yourself.  Drink plenty of fluids and rest in the shade as needed.


See you next month……….in the garden

Garden Solutions - June 2012

Bloom of a Black Eyed Susan plant at Hillermann Nursery & Florist Let’s talk PERENNIALS! June is National Perennial Gardening Month. Perennials are plants that grow and flower every year, and only need to be planted once! They die back to the ground in the fall, but the roots remain alive and will produce new foliage in the spring. A wide range of sizes, flower colors and blooming times are available to fit any size garden. Most perennials are considered low maintenance and just need some general care to keep them happy and healthy.

It is important to choose plants that are appropriate to your garden site. You need to know whether it is a sun or shade garden. Full sun plants can be in areas with six or more hours of sunlight every day; four to six hours is partly sunny; four hours or less is a shade garden. Remove any grass or weeds from the area you wish to plant. Good drainage is essential for successful gardens. Amend the soil with Missouri Botanical Garden Compost, also known as Black Gold, now locally available. This will help improve drainage and aeration. Prepare the bed to a depth of 18” to allow for maximum root development. Fertilizer can be mixed into the soil prior to planting.

When planting, dig the hole as deep and twice as wide as the container it is currently growing in. Loosen the root ball and tease the roots so they will grow outward. The plants should be set at the same depth in the ground as they were growing in the container. After filling the hole back in with soil/compost mixture, water thoroughly and apply Fertilome Root Stimulator for plant success. Read the plant tags for spacing recommendations because many will spread more than their current size. Don’t be afraid to mix textures.

Perennials should receive 1-2” of water each week to develop a deep root system. A soaker hose works well for this purpose and saves water usage. Fertilize in Early Spring when new growth begins. During the growing season, fertilize once a month until the end of July. This will help the plants harden off for winter. Mulch should be applied after planting to help hold in moisture and reduce weeds. Apply 2” over the soil, leaving 2-3” of space around the base of the plant. Do not smother the crowns of shallow rooted plants. Additional mulch applied in winter is also recommended, especially for new plantings.

The art of deadheading is removing the faded, spent flowers on a plant. It will help lengthen the bloom season of many plants as well as improves the appearance of the plant. Some perennials with attractive seedpods such as Rudbeckia, Sedum, and Ornamental Grasses can be left alone. Once the initial display of flowering has ended, cut back the entire plant by two-thirds. This will help promote additional blooms.

I hope this information gives you the desire to plant some perennial color and texture in your yard! There has been a “Perennial of the Year” named by the Perennial Plant Association since 1991. These varieties are tried and true plants. You may check out the list at www.perennialplant.org.

Now in closing, let’s discuss several other tips for the month of June. Soaker hoses and Raindrip irrigation systems make the most efficient use of water during dry times. Check out the systems available. Continue spraying roses with fungicide to prevent black spot. Mow lawns frequently enough so you don’t have to remove more than 1/3 of the total height of grass per mowing. There is no need to remove grass clippings from the lawn unless they are excessive. Prune flowering shrubs after they have bloomed. Hand prune or shear evergreens now. Watch for bagworms AND JAPANESE BEETLES. Milky Spore, Grub killer, and Japanese Beetle traps are available to eradicate Japanese Beetles. For bagworms, use insecticide with the pest listed on the label or hand pick them if the numbers are light.

Plant pumpkin seeds now to have Jack-o-lanterns for Halloween. Stop harvesting asparagus when the spears become thin. Repeat plantings of corn and beans to extend the harvest season. As soon as cucumber and squash vines start to “run,” begin spray treatments of Permethrin to control cucumber beetles and squash vine borers.

Enjoy your harvest ... see you in the garden.

Even though the weather outside is not as enticing or enjoyable as it is in the spring of the year, we can still enjoy being outdoors. In addition, there are things that still need to be done in the garden and landscape.

The most important item to consider this time of year, naturally, is water… Provide water to your garden, for not only the perennials, annuals, trees and shrubs, but do it also for the wildlife such as birds, rabbits, and squirrels. This can be done in several different ways. One way would be to install a drip irrigation system. These systems can be installed with tools as simple as a scissors or knife. Timers are also available to take the guesswork out of the project, and the system continues to work even when you are on vacation. This will be extremely important during summer seasons to provide moisture to new and established plantings. Now, Don’t forget the wildlife as well. Birds continue to give us enjoyment with new fledglings arriving as well as their daily antics. Supply water for them in forms of birdbaths, water fountains, or water garden displays.

August Tips for the Garden 2009


August… besides vacations, other activities that will pull you away from your list of gardening duties are fairs, festivals, family outings, and back to school preparations. It really is a good thing that August is a slow month for working in your landscape.

Your main tasks for this month both begin with the letter W. Weeding and watering. Both tasks are self-explanatory. However, I feel the need to explain them to some extent. It is important to stay on top of the weeds. If you let them get ahead of you and they go to seed, you are going to have hundreds more to deal with this fall and next spring. Spraying weeds with an herbicide such as Roundup is one of the easiest ways to rid of weeds. When using herbicides be sure to read and follow all label directions thoroughly. They are written for your protection. Also, be very careful when spraying around the plants that you want to grow in your landscape. It generally is best to pull weeds that are growing in and immediately around your desirable plants, and spray those that are “in the open”. As far as watering goes, most plants will survive on 1” of water a week. A rain gauge will help measure this.

Bugs, they really bug me, and some of them can really mess up your plants. Before you grab that bottle of insecticide, run outside, and spray every bug in sight, it is important that you identify the bug that is bugging you. Most insecticides can’t tell the difference between a beneficial insect like a honey bee and the destructive spider mite. Therefore, it is important that you identify what insect you are trying to kill and the best method to do it. You can collect some samples of your bug to bring to a garden center for Identification, but please, put them in a Ziploc bag and seal it before you do. This way the staff can safely examine and identify the pest without passing the problem on to their own plant stock. Once they identify the bug, the garden center staff can give you advice on the best way to control it.

Mowing the lawn is another task that continues in August. Due to the usually hot and dry conditions that are the norm in August, you may be able to space your mowing times further apart. That is unless you have an irrigation system to keep your lawn growing vigorously.

If you are thinking about a new addition to your landscape this fall, now is the time to talk to your favorite landscape designer. Your designer can discuss your needs with you, design the changes or new additions, and get you on the schedule for a fall installation.

If you tried your hand at seasonal vegetable or square foot gardening this spring, here are a few ways you can enjoy a fall garden. Carry tomatoes, peppers and basil plants over in your fall garden. Direct sow beets, radishes, peas, and spinach now where other spring crops such as broccoli and cauliflower have come and gone for this year. Replant nursery starts of broccoli and cauliflower.

Last but not least, take care of yourself. In the heat that is referred to as August, it is easy to over exert yourself. Drink plenty of fluids and rest in the shade as needed.

July Tips for the Garden 2009

I, for one, cannot believe it is the first of July already. This year is really flying by. This is the month for picnics, vacations, family reunions, and for just enjoying the outdoors in general. One of the tasks to take care of this month is weeding. If you put a pre-emergent weed control product in your landscape beds in March or April, you are due for a second application now. There are two reasons for this. First, most of the pre-emergent products that are available to the homeowner have a short life span, up to 60 days. The second reason is due to all of the rain we have had. However, there are many benefits to the very adequate rainfalls this year. One of them is the ease with which some normally difficult weeds can be pulled. So take time to clean up your landscape beds and apply a pre-emergent as soon as possible.

The long hot days of summer are stressful to every living creature, including all your plants. If you are tired of the endless task of keeping your plants watered, it is time to think about adding mulch to your beds.

I know that hotter weather is just ahead, so do yourself and your plantings a huge favor and apply mulch. If you have beds that have never been mulched, add 3” around all annuals, perennials, roses, trees and shrubs. Top dress previously mulched beds with an additional inch of fresh mulch. Not only does mulch hold in moisture, relieving you of some of your watering tasks, it also keeps the soil cooler, so your plants will be less heat-stressed. An added bonus is that weed seeds have a difficult time germinating when buried in mulch, reducing the time you spend weeding.

One of the most common questions that we receive at this time of year is, “How much do I water my ______?” I will try to explain some basic guidelines here:

Vegetables and Bedding Plants planted in the ground: established plants need at least one inch of water per week, more when bearing fruit. Check the soil around the plants, when it is dry one inch down, it’s time to water.

Container Gardens and Hanging Baskets: check your containers every day for water. Either test the soil by touch or lift the pot. Most baskets and many containers will need to be watered once, or even twice a day, depending on the weather. I suggest you fertilize once a week.

Perennials: newly planted perennials need daily watering until established, at least one to two weeks, depending on weather. After they show signs of new growth, apply a one inch per week rule.

Trees and Shrubs: newly planted trees and shrubs should be watered every 4-5 days for the entire first year after planting, unless rainfall is abundant. Place the end of your hose next to the base of the plant and let the water trickle very slowly for about two hours. This will allow the root zone to become thoroughly saturated.

Established Lawns: your lawn should be watered when the grass blades don’t bounce back after being walked on. One inch of water per week should keep your lawn green and healthy. It is best to water early in the morning, before the heat of the day. This keeps evaporation to a minimum, and allows plenty of time for the grass to dry before nightfall, which will help prevent fungus problems.

Newly Seeded or Sodded Lawns: for better germination, I suggest you mulch grass seed with straw as soon as it is planted. Once seed has germinated or sod has been laid, they must not be allowed to dry out. Water daily with a sprinkler until there is good growth. Early morning is again the best time. Once established, go back to the one inch per week rule.

Water Gardens: also require an occasional addition of water. Check your pond weekly and add water as needed. Water plants have variable depth requirements, so you need to keep the water levels consistent.

So continue to enjoy your outdoor spaces and make relationships with your plants! They can give you so much in return!

See you in the Garden,
Sandi Hillermann McDonald
