Seasonal Gardening Calendar


Flowers are starting to fade, so remove faded flowers and the stems that hold them. Summer is definitely here, so make sure you are doing “tick checks” if you have been out in the yard or woods.

  • JULY Week 1

    Pick a good melon

    Choosing a watermelon for the Fourth? Slap it to determine ripeness. Good ones sound hollow; unripe ones sound like you’re hitting solid wood.

    Remove faded flowers

    Regularly remove faded flowers from salvia, zinnia, coneflower and especially petunia. This will encourage bushiness and the production of more flowers.

    Prune hydrangeas

    Remove all stems that support faded flowers on your blue and pink hydrangeas; shorten droopy, flowerless stems by one-third. The new growth that occurs between now and winter will produce next summer’s blooms. See Pruning Hydrangeas

    Plant flower seeds

    There is still plenty of time to plant seed of marigold, cosmos, cleome and dwarf sunflower. They’ll make a spectacular flower show in six weeks.

    Support tall flowers

    Support tall flower stems prone to flop over after a rain. Use a thin stick or a length of bamboo and some jute twine to tie the plant upright.

  • JULY Week 2

    Trim your herbs

    Cut back by half herbs like basil, mint and oregano. This prevents them from producing seed and promotes more fragrant leaves.

    Soften up post holes

    If you’re forced to dig a hole for a post, let your water hose trickle in the spot all night long. The water will soften the soil from its concrete-like state

    Support fruit trees

    Don’t let fruit tree limbs break. Prop them up with poles or remove some unripe fruit.

    Check plants for insects

    Check the houseplants you’ve stationed outdoors for insect pests. Use insecticidal soap to manage insects if you find any.

    Pick vegetables

    Pick squash, cucumbers and okra regularly. One over-ripe vegetable, left on the vine, stops bloom production.

  • JULY Week 3

    Mulch under trees and shrubs

    Wood chips make great mulch by saving moisture and controlling weeds! Spread a layer 2 inches deep under trees and shrubs out to where the branches end.

    Check for ticks

    Ticks are a big problem this year. Take time to do a “tick check” when kids return from romping in the yard or nearby woods.

    Don’t abandon your houseplants

    Going on vacation? Most houseplants will grow just fine while you’re gone if placed on a wet towel in your bathtub with the curtain drawn.

    Patch your lawn

    Bermudagrass, zoysiagrass and centipedegrass sod can be successfully installed in bare spots now. Make sure to loosen the soil six inches deep before putting the sod in place. Water enough to keep the upper half-inch of soil moist but not soggy.

    Trim dahlias

    Cut back dahlias to half their height. Fertilize and water the plant to produce a crop of fall flowers.

  • JULY Week 4

    Water trees and shrubs

    Water spring-planted trees and shrubs weekly: 2 gallons of water per foot of height.

    Water figs

    Water figs now as the fruit begins to ripen. Drought can cause fruit drop.

    Mow grass taller

    Mow grass growing in the shade one-half to one inch higher than the normally recommended height. Plants need as much leaf surface as possible to take advantage of any available light.

    Fertilize houseplants

    Fertilize houseplants. They are getting much more light now and can use the food to grow bigger.

    Diagnose plant problems

    Don’t automatically reach for a fungicide if you suspect a disease on your plants. Identify the problem correctly first – it might not be a disease after all! Call 1-800-ASKUGA-1 to talk to your local Extension office.
