It is always advisable to place coldframes and hotbeds in a protected place, and particularly to protect them from cold north winds. Buildings afford excellent protection, but the sun is sometimes too hot on the south side of large and light-colored buildings. One of the best means of protection is to plant a hedge of evergreens. It is always desirable, also, to place all the coldframes and hotbeds close together, for the purpose of economizing time and labor.
