Propagators enhance an avid gardeners ability to produce wonderful flowers and vegetables, taking full advantage of the short Spring and Summer seasons. Propagators should control humidity well, ideally be transparent for maximum light and a peak at what’s going on with the seedlings, gently heated to encourage germination, and a manageable size as we often place them in doors. What sets a good propagator apart from the best propagator is the ease in which we can transplant our seedlings with a little trowel and fork set. This is vital to reduce stress on the seedling so I’ve reviewed the best propagators to help you.
