Summer Gardening Checklist



Summer gardens are bursting with color and have had enough precipitation this year to keep trees, shrubs and lawns green.

 Annuals are at the height of their blooming period and summer blooming perennials like coneflowers, daylilies, sedums, and scores of other plants add color to the landscape. Crepe Myrtles dot the landscape providing beautiful pink, red, white and purple blooms throughout neighborhoods. All that work we did in spring has paid big dividends.
Gardens do need to be maintained. Here is a gardening checklist to help with summer tasks.

Water
Summer heat dries out our gardens quickly. Focus first on newly planted trees and shrubs. Give them long, deep watering at the base of the plant. A five-gallon bucket with a hole drilled into the bottom of the sides will deliver water slowly to individual plants. A soaker hose can also provide water to the base of the plants if a new bed has been planted. Perennial beds and annuals could be watered this way as well. Overhead watering with a sprinkler is discouraged as much of the water evaporates and water on the leaves and flowers of plants may make them more susceptible to disease.
Pots and planters may need to be watered daily in the heat of the summer. Again, water deeply to encourage roots to go to the bottom of the pot. Water early in the day when possible.
Lawns will usually go dormant in the summer, so there is little need to water them. Fall's cooler weather will revitalize the grass.

Weeds
Weeds tend to grow where bare soil is in the garden. Plant more plants! A full perennial bed or annual garden will keep weeds from appearing. Weed after a rain to make weed pulling easier. Use a product like Preen to set a barrier where weeds won't germinate. Available in both organic and traditional formulations, Preen can be used around established plants. Transplants can go in the gardens with Preen, but seeds will not germinate once the garden has been treated.

 Notice how crabgrass appears in thin spots in the lawn? Crabgrass is an annual weed, so will die off over winter. Overseeding with good grass seed in the fall and putting down a fall fertilizer will help deter crabgrass next spring. Jonathan Green, one of our lawn care product suppliers, has some informational videos available online.  Newly seeded lawns will require daily watering until the seed has germinated. Our garden shop can identify weeds and help get them under control.
Bad...too much mulch too high on the tree. Do not mulch above natural tree flare. Keep mulch 3-6" away from the trunk. 

Mulch
I'm a big fan of mulching. Under established trees, mulch keeps the mower and string trimmers from damaging trunks and allows water to penetrate to the roots. Mulch keeps weeds out, warms the soil in early spring, covers plants' roots, keeps the garden from drying out, and adds organic matter as it decays naturally. Mulch should be applied to be 2-3 inches or so deep. Do not mound mulch, but instead keep a flat ring around trees.

Prune 
Prune, deadhead or cut back plants to encourage bloom. Annuals will recover fast and keep blooming until frost and in some cases, into November. Many perennials benefit from deadheading too. A great read, The Well-Tended Perennial Garden, by Tracy DiSabato Aust, provides step-by-step advice for pruning plants.
For pruning large trees, be safe and call a certified arborist. Our go-to company is Bartlett Tree Experts. Their expertise has helped my own landscape thrive, handling pruning and pest control jobs that were beyond my ability.

Insects and Diseases
Watch for insects in both the landscape and in the vegetable garden. Detected early, insects might be able to be handled by hand or with a forceful stream of water. Insecticides are available in both organic and synthetic formulas.
Diseases, like Powdery Mildew and Blackspot, can be treated with a fungicide. Bring in a sample for identification and suggestions for treating diseases to our garden shop.
The Maryland Home and Garden Information Center is another good resource for pest, disease and cultural information about garden plants.


Enjoy the harvest

Harvest
Enjoy cut flowers from the garden. Harvest tomatoes and other vegetables. Bring flower bouquets and your overflow of vegetables to friends and neighbors. Share the beauty and bounty of the garden.

Plan for Fall Gardens
Vegetables, like broccoli, cabbage, kale, and lettuce, can be planted in late July and early August for fall harvest. Perennials, trees, and shrubs can also be added to the garden in the fall. Warm soil will encourage root growth before plants go dormant for the winter, making them hardier for spring and summer next year. We have a new tool on our own website, Valley View Farms, called Plant Finder that will allow gardeners to search for plants according to their height, width, color, time of bloom, sun or shade tolerance and other attributes. While all of the plants listed may not be in stock, a phone call to the store will let customers know what is available now. Reach us from 7am - 9 pm Monday through Saturday and 7 am-6 pm on Sunday at 410-527-0700.

Summer is a time to kick back and relax. Spending time in the garden is a wonderful way to nurture your plants and yourself. Enjoy the last half of summer!
