If you own semi-hardy potted trees or even tropical trees, you might be scared to think what will happen with your tree once the winter frost arrives. Although some might consider keeping their trees in a stable, higher temperature all through winter, this isn’t necessarily the best plan. Experts consider that overwintering your trees is a far better option to keep them healthy and alive.
Overwintering your trees needs to be done in order to help the tree adapt to a harsher climate and essentially trigger its “hibernating” process over the winter period.
The bulk of your work will be in the fall. You have to start by dialing down on the watering as the temperature grows cold, and allowing the tree’s sap to reduce in quantity and its leaves to become a yellow hue, and start falling off. Now is not the time to give it nourishment, wait till spring to feed your tree with an organic fertilizer Denver home stores sell.
Next, spray the tree with dormant oil before you put it in storage. The storage area should be a roomy space (like a garage) with temperatures between 32 and 50 degrees. Make sure you store the tree in complete darkness, and water it lightly only once every 5-6 weeks (some people don’t do it at all). Once the frost is over and the spring season starts showing itself, you can gradually begin reintroducing your tree to sunlight and watering it more frequently.
