It’s still hard to believe summer is finally here to stay. So after a plant friendly and cool spring it is time to get ready for the hot weather. Our lawns and plants fared well so far and now it is time for all of us, plants and people, to make that seasonal adjustment.
Water is a plant’s best friend during the high heat of summer under the blazing hot sun. Right now your irrigation system should be set on a summer schedule. Maybe it is time to evaluate what type of system you have. Is it as efficient as it could be? In spring you don’t need a lot of supplemental irrigation but when the temperatures begin to climb and rain isn’t on the horizon, that system will be getting a lot more use. It is better to water less frequently and more deeply than every day for only a few minutes. You want to make sure the water penetrates through the mulch layer and can reach the roots. A drip system lays under the mulch/soil and uses less water than a traditional mist or rotary heads.
Early in the day is the best time to irrigate. If you water in the middle of the day, most of the water will evaporate before it has a chance to penetrate through the soil. If you water late in the day fungus will develop, especially in your lawn. Avoid letting water collect on leaves in the middle of the day; like ants under a magnifying glass, the leaves will fry. Leave your lawn 3-3.5″ high in the hottest months. This will help keep the roots cooler by providing some shade. Cutting too short can contribute to browning out. When mowing your lawn, remove no more than 1/3 of the lawn’s height at one time.
A few organic choices for the garden that will help your plants thrive include mulch, compost and pruning. Incorporating compost into your soil adds organic matter and will give your plants a boost in nutrients, minimizing the need for synthetic fertilizers. Mulching around your plants keeps the soil cooler in summer and helps with moisture retention. Also, you can mitigate potential damage from poor air circulation or low light penetration with proper pruning.
When it gets hot and humid, there are certain pests and diseases that thrive. Scale, Black Spot, Powdery Mildew and Fungus Gnats are several to watch out for. Call us if you see small, fuzzy white things that jump on and off of your plants or if you see black spots or a white film on any leaves. If you see clouds of tiny flying insects, most likely around a wet area, it could be fungus gnats. While they are harmless to humans (they only feed on rotting organic matter) this could indicate you have a standing water issue, which will attract a much worse insect: the mosquito. Our sister company, Tree Care Long Island, has several treatments including horticultural pruning, beneficial insects and liquid and granular applications (including organic options), to treat these issues.
More insects to watch out during the summer include Aphids and Leafhoppers, Grubs, and Spider Mites. Aphids and Leafhoppers can spread scale and powdery mildew between your plants. Grubs eat the roots of your lawn, creating bare patches and holes in your lawn from predators like crows and raccoons digging for dinner. Spider Mites suck the juices out of a plant’s leaves and/or needles and cause the plants to defoliate and die.
