* Cut strawflowers intended for dried flower arrangements when the blooms are only half open. Tie small bundles of the flowers together and hang them upside down in a well ventilated place to dry.
* Check on water needs of hanging baskets daily in the summer. Wind and sun dry them much more quickly than other containers.
* Clean up fallen rose and peony leaves. They can harbor disease and insect pests over the winter if allowed to remain on the ground.
* Pick summer squash and zucchini every day or two to keep the plants producing.
* Water the garden early in the day so plants can absorb the moisture before the hot sun dries the soil. Early watering also insures that the foliage dries before night. Wet foliage at night increases susceptibility to fungus diseases.
* Many herbs self-sow if the flowers are not removed. Dill produce seeds that fall around the parent plant and come up as volunteers the following spring.
* Every weed that produces seed means more trouble next year. Control weeds before they go to seed.
