With the rain and overall unseasonably cooler weather, everything in the garden world has been behind. It's always a reminder that things in the garden can't always be done by the calendar but by watching the garden to let us know when it is time. So with that, a tentative gardening task list for June Zone 4-6.
-Deadhead bulbs and spring flowering perennials as blossoms fade
-Early detection is essential for god control of vegetable pests. Learn to identify and distinguish between pests and beneficial predators.
-Watch for bagworms feeding on many garden plants, but especially juniper and arborvitae
-Thin seedlings to proper spacings before plants crowd each other
-Plant tropical water lilies when water temperatures rise above 75 degrees
-Apply a second spray for borer control on hardwood trees
-When night temperatures stay above 50 degrees, bring houseplants outdoors for the summer
-Most houseplants brought outside prefer a bright spot shaded for the afternoon sun. Check soil moisture daily during hot weather.
-Apply a balanced rose fertilizer after the first show of blooms passes
-Continue spraying roses with a fungicide to prevent black spot disease
-Rhizomatous begonias are not just for shade. Many varieties especially those with bronze foliage do well in full sun if given water and a well drained site.
-Apply organic mulches as the soil warms. These will conserve moisture, discourage weeds, and enrich the soil as it decays.
-Trees and shrubs may still be fertilized before July 4th
-Pruning of spring flowering trees and shrubs should be completed before the month's end
-Softwood cuttings can be taken from trees and shrubs as the spring flush of growth is beginning to mature
-Mow lawns frequently enough to remove no more than one third total height per mowing. There is no need to remove clippings unless excessive.
-Mow bluegrass at 2-3.5inch height. Turf-grasses growing in conditions shaded conditions should be mowed at the higher recommendations.
-Gradually increase the mowing height of zoysia lawns through summer. By September, the mowing height should be 2-2.5inches.
-Zoysia can be fertilized now while actively growing. Do not exceed 2-3lbs of actual nitrogen fertilizer per 1000sq.ft.per year.
-Water turf as needed to prevent drought stress
-Plant pumpkins now to have Jack-o-lanterns by Halloween
-Start seedlings of broccoli, cabbage and cauliflower. These will provide transplants for the fall garden.
-Repeat plantings of corn and beans to extend the harvest season
-Set out transplants of Brussels sprouts already started. These will mature for a fall harvest.
-As soon as cucumber and squash vines start to run, begin spray treatments to control cucumber beetles and squash vine borers
-To maximize top growth on asparagus, apply 2 pounds of 12-12-12 fertilizer per 100sq.ft, water well and renew mulches to conserve moisture
-Stop harvesting asparagus when the spears become thin
-To minimize diseases, water with overhead irrigation early enough in the day to allow the foliage to dry before nightfall.
-Soaker hoses and drip irrigation systems make the most efficiency of water during dry times.
-Control corn earworms. Apply several drops of mineral oil every 7 days once silks appear. Sprays of B.T.is also effective
-Enjoy the strawberry harvest!
-Renovate strawberries after harvest. Mow the rows; thin out excess plants; remove weeds; fertilize and apply a mulch for weed control
-Thinning overloaded fruit trees will result in larger and healthier fruits at harvest time. Thinned fruits should be a hands-width apart
-Oriental fruit moths emerge. Most serious on peaches where first generation attacks growing tips. Shoots will wilt. These should be pruned out.
-Spray trunks of peach trees and other stone fruits for peach tree borers.
-Summer fruiting raspberries are ripening now.
-Begin control for apple maggot flies. Red painted balls that have been coated with tanglefoot may be hung in apple trees to trap egg-laying females.
-Prune and train young fruit trees to eliminate poorly positioned branches and to establish proper crotch angles.
-A mailbox mounted on a nearby post makes a handy place to store and keep dry any small tools, seeds, labels, etc frequently used in the garden without having to keep walking back to the storage shed or garage. Be creative and paint it with pretty colors and designs.
-When using any gas powered equipment, be sure to allow the engine to cool a few minutes before refilling empty fuel tanks.
