How do trees know when it’s time to start growing in spring?
The time your trees break bud is mostly up to Mother Nature. Trees get the cue that it’s time to “wake up” when the temperature gradually gets warmer and when longer days and shorter nights bring in more sun exposure. But proper spring tree care also supports the growth process, and that’s where you come in.
Water is incredibly important for trees as they work to establish new leaves and flowers. When you water trees at the right time in spring, you help make sure they have a healthy growing season. So, when’s the best time to water your trees in spring?
Trees need water before their leaf out date. Depending on where you live, that date could fall anywhere from mid-March to early May. Supplemental watering is needed only if the weather has been exceptionally dry. If the soil feels moist four to six inches deep, either from recent rains or snowmelt, you should be OK. If the soil is powdery dry, follow these guidelines:
If you live in a colder climate, the best time to water trees is between late winter and early spring. Hydrate your trees after the ground thaws out but before temperatures get warm enough to prompt new growth. If the ground doesn’t freeze in your area, plan to water your trees as soon as the days start to get warmer and longer.
Don’t worry if you’re a little late! Small spurts of growth here and there are nothing to worry about, but you should aim to start watering your trees well before their leaves and flowers are fully grown.
