Control Flea Beetles
Once you've set your vegetable transplants outdoors in the garden, flea beetles have an open invitation to start feeding on the leaves. Flea beetle damage looks like shotgun holes in the leaves of tiny seedlings such as eggplant and broccoli. To control these pests, place a floating row cover over susceptible vegetables. The row cover excludes pests but allows plants to get sunlight and moisture.
Dig Out Clumps of Grassy Weeds
Before they distribute their seeds, dig or hand pull clumps of weedy grasses, like the downy brome grass and clumps of fescue that are culprits in my garden. This will be an easier task when the soil is moist.
Transplant Tulips if Needed
If your tulips are not in the right place, or a maturing landscape shades them, now is a good time to move them. Carefully dig and replant bulbs and their still attached foliage in full sun and well drained soil.
Once the blooms have faded, deadhead old lilac flowers. This will prevent seedlings from popping up here and there. Now is also the time to thin out some of the oldest wood by cutting it off at ground level.
Feed Water Lilies
Once potted water lilies are set in a pond and have acclimated, poke a fertilizer tablet into their potting mixture. The nutrients will dissolve slowly to feed the the plants, resulting in healthier growth and more blossoms. Do this about once a month through the summer.
