Keep blueberry bushes well-watered to get the berries plump and juicy. If possible, keep moldy and bird damaged berries picked off. Blueberries freeze best if laid out on cookie sheets and frozen individually. After frozen, place in plastic bags or containers until used.
Prune wisteria this month. Prune long whip like growth back to 3 or 4 leaves on each stem where the stem joins a main trunk or limb. This same pruning should also be done again in late September or early October.
Watch for pear slug on pear and cherry tree leaves. They are small pear shaped black or brown shinny larvae of a fruit fly. You can fold the leaf over and pinch them or you can remove the leaf with the slug on it. Use an insect spray as a last resort.
Divide and replant Dutch or bearded iris in July or August. Left undivided, these iris will become reluctant to bloom. Fertilize divided rhizomes with bulb food and plant only deep enough to barely cover the top of the rhizome.
Raise lawn mower height to mow grass at 3” tall to help keep the ground from drying out during peak high-temperature months of July and August.
Keeping cucumbers well-watered will help prevent bitterness.
Overwatering cabbage can cause the heads to split. When harvesting cabbage, cut the head off a little high. Often new heads will form on the stump left behind.
Prune rose stems that have bloomed back to at least the first five leaf leaflet. Keep fertilized and watered well for continued blooming until colder weather.
Prune and add lime to lilac bushes. Prune out older/taller stems and apply lime at the rate of one to two pounds per bush. Dig the lime into the soil and water in well.
Remove the anthers from Asiatic lily flowers as soon as the flower opens. Doing so will keep the flowers in bloom longer. Be very careful not to get the brown pollen on you or your clothes, it will stain.
