This is the time of year to plan to cover you more delicate plants from the freezing nights we are likely to get in the months ahead. Usually a simple cloth cover over the trees or plants will be enough, but be sure to check with your nursery to do it properly and not damage the plant. And it is best that the cloth not touch the plants if possible, and to remove the cover during the day so the plants can benefit from the sunlight. A little effort and precaution now can keep you from losing the plants entirely.
