june garden checklist

​

• Avoid heavy summer pruning. Light pruning is fine. Even small limbs in the way of the lawn mower are fine to remove during a hot summer.
• Raise your mower blades to cut your fescue lawn to 3 inches or more. Doing this will help protect grass roots from the summer heat and encourages a more extensive root system. Deeper roots will be beneficial during a drought. Water the soil to a depth of 4-6 inches every 3-4 days if possible. Don’t fertilize your fescue lawn during the summer.
• Spider mites can be a severe problem at this time of year. They become very active during hot weather. Most ornamentals and vegetable crops are subject to attack. Bifenthrin, malathion or insecticidal soap are good choices to use on ornamentals and malathion or insecticidal soap on vegetable crops. Read label directions before use and most important follow directions on days to harvest vegetables after use.
• Summer is the time to dig and divide irises. Irises do best in full sun but will tolerate some shade. High fertility encourages rhizomes to rot and fewer blooms. Fertilize lightly this fall for beds that you dig and divide this summer.
• If your summer annuals look like they are tired, fertilize them with half a pound (one cup) of 34-0-0 per 100 sq. ft. Watering is also important.
• You can expect fall webworms soon if not already. We can expect two to three generations of this tree defoliator each year, depending on the weather. Female moths lay eggs on the underside of host trees in April. Eggs begin to hatch in June and sometimes as late as August (depending on weather conditions). Control is not absolutely necessary. It is more of an aesthetic problem. Sevin, bifenthrin, acephate, permethrin, Dipel, or Thuricide will control these caterpillars.
• If you haven’t already done so, put your leftover garden seeds in a ziplock bag and drop them in the freezer. You can keep many garden seeds this way for several years including seeds you collect from flowers or vegetables.
