The official date of Spring is March 21 - which is the usual date when you start to take your bonsai out of their winter storage and gradually bring them to your display area. But, this year is unusual - like so many that we have in Ohio. There has not been a very long cold spell. But, this weekend has predictions for below-freezing temperatures. If your bonsai are in leaf and we have a sudden cold snap make sure to protect your trees from frost.
Any new growth is very tender.
A sudden cold spell will kill the new growth and can damage new root growth. If you do not protect your trees in the event of a cold spell you could lose all of your bonsai. Watch the weather forecast. Remember that, once your trees break their dormancy, there is no way to reverse the process. Start thinking about your yearly fertilization program.
