Summer is just around the corner! June brings longer days, ample sunshine, and the perfect conditions for plants to thrive. However, it also introduces scorching temperatures and the need for diligent care. Let's dive in and learn how to keep our gardens blooming and flourishing throughout the summer!
From deadheading to planting warm-season vegetables to scouting new pests, there are a lot of new things we need to do for our gardens this month. Check out what chores we recommend:
Consider building a rain barrel. Keep plants mulched to help retain water. Plant drought-resistant and native plants. Water plants early in the morning to conserve water and reduce evaporation. Install more efficient irrigation systems. Learn how to install drip irrigation.
Infrequent, deep watering is better than frequent, shallow watering. Deep watering promotes deep root-growth. Deep-water trees and shrubs once or twice a week and flowers 2-3 times a week.
Most plants need 1 inch of water per week. Monitor rainfall and water your plants accordingly.
Trees show delayed visual symptoms of drought stress, meaning if they are showing signs (wilt, leaf scorch, loss of green coloration, etc.), they may have been experiencing drought stress for a while. These signs could be the beginning of irreversible damage. Do not wait until you see visual symptoms. Water mature trees weekly with a thorough soaking.
Cool-season vegetables have likely already bolted or stopped producing vegetables. Harvest vegetables in the morning for best flavor. Replant warm-season vegetables as you harvest. This month, we recommend planting:
Squash: Plant pumpkins to have Jack-o-Lanterns for Halloween, and other edible squash for a fall harvest.
Harvesting potatoes: When harvesting, spread potatoes out in a well-ventilated, protected area for curing. Let cure for 2-3 weeks, and store in a cool, dark place. Check for- and dispose of- spoiled potatoes.
Matted row strawberries: After harvesting strawberry beds, mow the rows, thin out excess plants, remove weeds, fertilize, and apply a mulch for weed control.
Tomatoes: Keep moisture levels even by watering evenly and mulching to prevent blossom-end rot. Fertilize tomatoes lightly about every two weeks once they start setting fruit.
Finish blooming spring blooming shrubs.
Separate crowded irises in late June. Replant them, share with friends, family, and neighbors, or dry, store, and replant in the fall.
Side-dress annuals with a balanced fertilizer. Fertilize every 4-6 weeks. Reach out to your agent about amounts.
Big-leaf hydrangeas, oakleaf hydrangeas, and gardenias set flower buds in the fall and bloom in the summer. Prune these plants as soon as flowers fade. When pruning these hydrangeas, remove older, thicker canes at the soil line after blooms have faded.
Azaleas: Check for azalea lace bugs. Ask your county agent for pesticide recommendations.
Roses: Fertilize roses with a balanced rose fertilizer after the first show of blooms is past.
For a water garden: Plant tropical water lilies when the temperatures rise above 70° F.
Planting clematis: Test and amend your soil with lime, if necessary, before planting clematis. Clematis requires neutral to slightly basic soil. For best results, keep clematis watered and mulch the root system to keep it cool during the heat of summer.
