Question: 678-212
We have had a mild winter so far this year. I have not built the traditional tent over my Japanese Maples. They are five feet tall now. How long do I have to wait before I can leave them without shelter? I do mulch them every year. Trevor, Branford, ON

Mort's Answer:
Because you have put mulch under the trees, it should make it easier for them to survive. Zone 5, where you are, is the suggested limit for Acer palmatum and other Japanese Maples. Mulch allows for the insulation of the soil. Each fall I would add water under the mulch to help protect the plants. It is the alternating freezing and thawing that damages plants. The maples will thaw later in the spring but that is not a bad thing.
