Control Aphid Infestations Early
Aphids are reproductive machines and can get out of hand quickly if not kept in check. If beneficial insects are not present to do the job, a spray of insecticidal soap or horticultural oil can keep an infestation in check until the beneficial insects arrive in adequate numbers.
Prune Spring Bloomers
Plants that bloom in winter or spring including spirea, flowering quince, forsythia, dogwood, redbud, azaleas, camellias, and roses that don't repeat bloom can be pruned now as needed to allow them time to regrow and set next year's bloom buds in late summer to fall.
Save Seeds from Early Season Flowers
Poppies and other early blooming plants, along with some wildflowers, are maturing their seeds now. Collect, dry, and store them in an air tight container in the freezer to maintain their viability for planting in future seasons. Make sure and include a label indicating the species.
Continue Planting Summer Vegetables
As cool season crops like lettuce and spinach bolt and are removed, replace them with heat loving vegetables like okra, southern peas, Malabar greens, winter squash, sweet potatoes, watermelons and muskmelons (cantaloupes) to keep the harvest going for months to come.
Stop Weeds Early
Warm season annual weeds like crabgrass, grassbur, purslane, pigweed and wild sunflowers are growing fast in these warm temperatures. They are easier to control the younger they are. Don't let them get too large since weeding in the hot summer sun is no fun! Hand pulling or hoeing is easier if the soil is slightly moist. Mulching will also shut them down if the weeds are still very young and can be covered by the mulch to exclude sunlight.
