- If you leave your wheatgrass in direct sunlight on a hot day, it will start to wilt and turn yellow quickly, even if you water it enough. Don't leave it directly in the sun, especially during the hottest times of the day--from 10 Am to 3 PM. You can make a little shade-cloth tent to put over it that filters out some of the hot sun. Make sure you leave enough room for plenty of air to circulate around the grass.
- When you soak your wheat seeds, only soak them for 3-6 hours. They can begin to ferment in hot weather if you soak them too long.
- If you leave the air conditioner on in your house during day, put the wheatgrass inside by the window. This way it gets plenty of sunlight but stays cooler.
- Don't put as many seeds on each tray. Crowding the wheatgrass when it is hot and humid means less air can circulate and will lead to wilting and mold. You can grow extra trays with less seeds on each one.
- Let a fan blow on your trays during the day if they are outside and it is very hot. This increases air flow and inhibits mold growth.
- And if all else fails, you can always try growing in the basement where it is cooler (if you have one) with grow lights.
Hot weather growing
Growing wheatgrass in hot weather can be a bit of a challenge at times. I have dealt with this problem myself many times, since the summer here gets above 90 F (30 C) and it is also humid. While it is hard to grow good wheatgrass in these conditions, it is definately possible. Here are some ways to deal with
