Flowers – Cut back perennials (e.g. hardy Geraniums, Delphiniums & catmint) after the first flush of flowers to encourage new growth and further blooms.
Deadhead – annuals to encourage blooming.
Trim – Shorten stems of fall flowering plants like asters, mums, Joe-Pyeweed and goldenrod to keep them sturdy and compact.
Wisteria – Throughout the summer, remove the whippy side-shoots from the main branch framework to about 20 cm from their base (about five leaves from the main stem). Wisteria not blooming? Read our wisteria factsheet for help.
Lilacs – Remove the old flower clusters as soon after flowering as possible. Prune just above the two new shoots that angle out from the stem that ended with the old flowers.
Lawn – Mow high-3”/7.5 cm to shade out weeds and leave the clippings on the grass to return nutrients & water to the soil. WATER LESS and let lawn go dormant in dry hot spells (turn brown). Water dormant grass when: the blades don’t spring back upright when you walk on it and when the blades fold to show their lighter blueish-green underside. More info here.
Veggies – Water during dry or hot weather to avoid stressing plants. Do not over fertilize tomatoes as it can lead to blossom end rot.
Garlic – Stop watering 2-3 weeks before harvest. Harvest when tops turn brown (about mid-July) For more information go to; Producing Garlic in Michigan
Water – Avoid watering in the hottest part of the day; water any spring planted trees& plants regularly, & existing trees less frequently, but deeply; water the base of plants, not the foliage, or use soaker hoses.
Birds – Keep feeders and bird baths filled &clean.
Pests–Try and identify the insect before taking action. That ‘pest’ may be a butterfly caterpillar! For pests that are a problem, something as simple as a strong spray from your garden hose to knock them off will do the trick and does not kill beneficial insects which will keep your garden in balance.
Japanese Beetles/Gypsy Moth/Aphids/Squash beetles – Check our June newsletter for suggestions.
Visit a local garden centre – Many plants are on sale in July! Why not add some butterfly host plants to your garden this year.
