Timely Tips
- Squash Bugs are starting to appear on squash, cucumbers, melons & pumpkins. Proactively control these destructive pests with Fertilome Triple Action or Diatomaceous Earth (also controls ants, cicadas, earwigs, scale & mealybugs). If the infestation is severe, then use Bonide Eight.
- Caterpillars are still being reported; should you find them in your landscape, treat them with Captain Jack’s DeadBug Brew or Fertilome Caterpillar Killer with Bt.
- Lawn Brown Spots have several causes: heat, poor irrigation design, insects, rabbits, or fungus. Visit with one of our plant doctors to determine how to identify the cause in your yard.Â
- Spider Mites are likely to start showing up on distressed trees and shrubs. Remove affected foliage and treat with Fertilome Triple Action, Bonide Citrus Fruit & Nut Orchard Spray. Do not compost affected foliage.
- Be on the lookout for a powdery white coating (Powdery Mildew) on plant leaves. Remove affected foliage and spray with Bonide Copper Fungicide or Fertilome Copper Fungicide.
- Aphids, in a variety of colors, may be showing up on just about anything – deciduous and fruit trees, roses, honeysuckle and more. Use Bonide Insecticidal Soap, Bonide Neem Oil, or Fertilome Triple Action.
- Codling Moths will have their second hatching soon. Use Codling Moth Traps to monitor when it occurs. Then apply Captain Jack’s Deadbug Brew, according to the label, to protect your apple crop from their hungry larvae. Â
- Earwigs are active in many yards – these guys eat at night, so you’ll only see the destruction they’ve wrought in the daylight. Use Fertilome Come and Get It Spinosad Plus, Bonide Bug and Slug Killer, Bonide Eight or Diatomaceous Earth.
- If Slugs are eating your plants, use Fertilome Come and Get It Spinosad Plus or Bonide Bug & Slug Killer to eliminate them.
- Leaf Hoppers make your leaves look like lace. Use Bonide Eight to treat them.
- Water newly planted trees, shrubs, perennials & roses 3 – 4 times per week in July and August, being careful not to overwater – soil needs to dry out between watering; otherwise soil becomes waterlogged which can cause roots to suffocate & rot.
- Continue to check all plants weekly to be sure they are getting adequate water; established trees, shrubs, perennials & roses require 1 inch of water per week throughout their root zones.
- Continue to cultivate and weed and if not done yet, mulch garden beds immediately after weeding with 2 to 4 inches of G&B Organics Soil Building Conditioner to retain moisture and keep weeds under control.
- When you purchase a tree or shrub, be sure that you get a planting guide from the cashier to learn how to properly plant and maintain trees and shrubs. Or view our How to Plant a Tree video to ensure that your trees and shrubs get off to a healthy start & long life. Should you have additional questions, please talk to a plant doctor.
- Continue to deadhead roses by cutting flowers back to the first set of five leaflets.
- Monitor roses closely for blackspot. Remove any leaves that show darkened circles with fuzzy margins on either side of the leaves; yellow foliage with dark spots; and any leaves that have already dropped from the plant. Begin a spray program with Bonide Neem Oil immediately. Dispose of infected leaves in the trash; do not compost.
- If not done, yet, renovate overgrown shrubs including redtwig dogwood, lilac, and forsythia by removing one-third of the oldest canes.
- For a second, late summer bloom, shear, cut back or remove flower spikes from catmint, perennial geraniums, salvia, and delphiniums.Â
- Remove spent flowers or seed heads of daylilies immediately to conserve plant energy.
- Make note of empty spots in borders that might benefit from planting summer-flowering bulbs next year.
- Continue pruning out the longest stem of cascading petunias weekly to prevent plants from becoming scraggly.
- Fertilize roses with G&B Organics Rose and Flower Fertilizer now for a second time if you have not already done so. Regular feeding is important for vibrant blooms & healthy plants. Â
- Fertilize container plants with G&B Organics Bud & Bloom granular every three weeks avoid applying in the heat of the day. Always water plants before adding liquid fertilizer.
- Espaliered fruit trees should be pruned for the second time once their spring flush of growth is over. The first pruning is done in late winter when plants are dormant.
- Stake tomato plants with tomato cages if they have no supports. Begin harvesting as fruit ripens.
- Monitor tomatoes and ensure that they receive an even supply of moisture instead of heavy soaking and then a drought. Â
- Monitor vegetables for symptoms of fungus or blight: soft, darkened areas, yellow and dropping leaves, sunken dark spots on otherwise green foliage.
- Monitor all plants for insects. Hand-remove large insects such as tomato hornworms, cicadas, and other caterpillars. For squash bugs, use Bonide Eight. Or a non-chemical alternative for the brave is to remove adults and nymphs by hand and squish their eggs on the back side of leaves.
- Continue to harvest herbs to use fresh, dry, or freeze in small batches in an ice cube tray. Pinch off developing flowers to retain essential oils and flavor in the plant’s foliage.
- Fertilize vegetables with G&B Organics Tomato, Vegetable & Herb fertilizer every 2 months. FoxFarm Grow Big, Big Bloom, Tiger Bloom Bud & Blooms & BushDoctor Cal-Mag are also great for veggies; use according to label.
- Fungus Gnats love the warmer weather. Use Sticky Traps and Mosquito Bits to eradicate. Sticky Traps are effective at catching the adults and Mosquito Bits target the eggs and larvae. Reduce watering if possible.
- Most Indoor Plants don’t like to be kept in drafty areas of your home, move them away from fans, swamp coolers, and AC vents.
- Ensure your Indoor Plants are not placed in areas where they are exposed to direct sunlight during the hot summer months. Move them away from windows if possible to avoid leaf scorch.
- Many birds are now beginning their main molt (replacement of their feathers) which requires extra protein to grow strong feathers for proper flight and effective insulation. For the next few months, offer high-protein bird foods, such as nyjer, peanuts, Jim’s Birdacious Bark Butter® or continue to offer Nesting Blend to ensure that your birds have a reliable source of protein to help them with molting.
- As summer progresses, rufous hummingbirds will start showing up and will stay into the fall.
- Add movement to birdbaths with water wigglers to attract more birds.
- Continue offering WBU Suet Dough to warblers, nuthatches, wrens & woodpeckers, and all insect-eating birds. It’s a great way to provide additional protein.
- Continue to put out oranges, grape jelly and nectar for orioles and sugar water for hummingbirds. Be sure to change every few days to avoid spoilage — more frequently if in full sun all day.
- Continue to supply fresh water and change it every 3 days to keep it clean. To prevent the chance of disease, clean birdbath weekly with a weak bleach solution (1 part bleach to 9 parts water) and rinse well.Â
- Store bird food in a sealed container and keep in a cool dry place to prevent spoilage.
- To ensure that bird seed is eaten quickly and stays fresh, keep feeders filled with a one- or two-day supply of seed.
- Clean and sterilize your bird feeders every 6 weeks with a bleach solution (see above) to prevent the spread of disease.
- Install a customized Wild Birds Unlimited bird feeding station where you can easily watch the birds it attracts. It can be installed in the ground or on a deck.
