How do trees know that it is spring and time to start growing again? Surely they can't tell the time and they don't have little calendars in their trunks, but each spring they seem to know that it's time once again to bloom, to grow buds and to grow the leaves back that fell the previous autumn. But how?
Trees are living things and as such have molecules and enzymes in them that signal the changes in season. The big thing about spring is that we have more sunlight and as sunlight is a very important thing to a tree, they begin to grow and bloom once again when they are getting more hours of sunlight each day. But it was warm and sunny that day in February you may say, that may be true, but it wasn't enough sunlight on a daily basis so not enough to tell the trees it was spring once again.
We can see the changes on the trees quite easily, they bud and new leaves start to grow, this is the main growing time for trees, as they look to reproduce. Experts say that this season is like a tree's adolescence as it is the main growing time. Trunk growth is something that happens throughout the summer months and root growth occurs in the fall and winter, but the prettiest part of all is in the spring.
Trees typically have two kinds of buds, the large ones that will one day become flowers and the smaller thinner ones that will one day will be the vegetation (the leaves). This all occurs quite fast in the grand scheme of things and during the summer we can reap the rewards of the fruit (if its a fruit tree) or look forward to picking up all the leaves once again come fall.
For trees to be lovely in the spring means that they have had a winter on them with temperatures between -5 and 10 C, this triggers a physiological reaction within the tree itself with the hormones and enzymes to allow the tree to be radiant once winter has ended.
Trees are beautiful things and are very adaptable. They give us shade, they give us privacy and they beautify our gardens and parks. While we may not give them a second look, trees have a lot going on just beneath the surface and, like humans have their time to grow and develop.
