- Root rot

In zone 4 or decrease it’s very attainable to get temperatures round freezing as early as October, which remains to be effectively throughout the rising season for a lot of greens. And in spring, surprising frosts can hit as late as April. Final yr, we had a shock frost in Could (Zone 9), adopted by flashes of snow in June.
In these situations, watering at night time, when the temperature is at its lowest can actively trigger frostbite, and ice sheets, and permit freezing water to permeate the soil, slowing the entire rising season down by a few weeks.
Watering at night time may cause root rot
Watering at night time provides moisture to the soil when crops want it least. If crops don’t want water they may simply ignore it. If crops ignore water it’s going to greater than seemingly sit round their roots, creating morning dew and better humidity the next afternoon. In these situations, fungal an infection can harm plant roots, inflicting black root rot, which is extremely laborious to treatment.

Watering crops within the afternoon, when the solar is out, and the climate is good, is by far probably the most pleasing time to water your backyard.

You waste much less water within the cooler, stiller, air, and crops are nonetheless pretty receptive and actively rising earlier than sundown. Nonetheless, there’s restricted daylight left at this level, and crops will cease photosynthesizing, and begin transpiring and releasing gasoline and water by way of their leaves, disregarding the water at their roots till morning.

They actively produce nectar within the night, filling your backyard with sweetly scented fragrances, and in some instances, serving to to distract pests (moths particularly) out of your edible backyard.
Throughout a heatwave, watering your mattress and borders at night time can be not a very dangerous thought, as most shrubs and perennials will probably be determined for any moisture they will get.
