Summer is in full swing and there is plenty to do in the garden this month. Here's a checklist of things to be aware of in July.
Woody plant care
The end of July is the correct time to use 20-20-20 fertilizer for the final rose treatment for this season.
Redtwig dogwood, lilac, forsythia and lilac should be through with spring bloom and may be renovated by removing a third of the older branches.
Summer blooming shrubs such as Hydrangea, Saint Johnswort, Rose of Sharon and Summersweet will all be attractive additions to your mid-summer garden.
Annual and perennial care
Summer annual care involves mainly consistent deadheading, control of weeds and proper watering.
Hanging baskets and containers of annuals will need frequent, sometimes daily, watering as the temperatures increase.
If you lost perennials this winter and are planting new ones, be sure to supply adequate water during and after the transplant period. If perennials appear stressed, it is probably a water problem and not a need for more fertilizer.
Perennial seeds may be sown in July. It is a good idea to mark the location of the new seed areas.
Oriental poppies can be divided this month.
Turf may show signs of dormancy as the heat of summer increases. The crown will remain alive as long as the grass receives at least 1 inch of water a week.
Mowing at 2 1/2 to 3 inches is recommended for summer lawns.
Herbicides should be avoided in hot weather.
Fruit and vegetable care
Ground suckers should be removed from apple, apricot, crabapple, peach and plum trees.
Monitor apples in late July for possible infestations of apple maggots.
If your tomatoes, peppers or summer squash are brown or black on the end , they probably have blossom-end-rot. This is a calcium deficiency problem and can be prevented by supplying a consistently even application of water.
Harvest onions and garlic when ready and begin the drying process.
In mid-summer our gardens can look a little tired; and this year, we may even have blank places where we lost plants due to the severity of the winter. Why not take this opportunity to try new plant varieties.
