Q&A for How to Choose the Best Time for Watering a Garden

That could be a sign of over-watering or a pest infestation. Check the soil for moisture, and check the leaves for signs of insects.

That's a very wide time range. Really, this article explains well what the best times to water plants are. The ideal time to water them is in the morning before 10 am. 6 am would be good; 3 am is a bit early but also okay. The worst time to water is between 10 am and 2 pm, when the sun is hottest. Late afternoon through around 6 pm, or even later in the summer when days are long, is okay.

It depends on how dry your plants are. If they are very dry, then water them; but if they are still wet, you can skip that day.

You shouldn't water the plants at night because there is no sun to let the water evaporate. You should water them in the morning.

The very best time to water is when the plant needs the water or when it needs to be cooled. If you suspect that the garden needs to cool off at 2 or 3 pm, then 2 or 3 pm is a fine option.

You should use trial and error to figure out how often you need to water certain plants/ vegetables. Some may require water more frequently than others, and some may be fine without water for several days. It also depends on how warm/ hot your climate is.

Is it extremely windy every day? If so, look into buying or making your own soaking hose system. Most hardware stores sell them. Or, make your own from an old garden hose. Drill small holes into the capped off hose and use it to soak the roots.
