In the early spring when it can be quite cold during the night it is important to water plants sparingly, and for preference to do any watering that is necessary early in the day as it will be harmful to plants to lie wet and cold overnight. The temperature of the cold house can be lifted a few degrees by lining the entire inside of the house with thin gauge clear polythene, Read more ...
Selecting and preparing the site for the greenhouse is often put forward as a matter for deep concern and contemplation, but my experience suggests that very few gardeners have much choice, as the size and shape of the garden dictate where the greenhouse will be located. But supposing you are fortunate enough to be able to say that the house can be located in all manner of 
My first greenhouse was constructed from old commercial greenhouse bars, running purlings, end rails and such like — needless to say it was a very much more laborious exercise than one would be expected to be confronted with now when contemplating the erection of a greenhouse. With second-hand material everything had to be cut, trimmed and somehow made to fit the chosen size 
Introduction
The hobby greenhouse in the back garden is everything you ever want to make it — productive, expensive, worrying, time-demanding, beautiful. But most of all it is a refuge! A refuge from what? — from everything that causes you annoyance – from endless telly to the yapping dog. It is a refuge in very much the same way as the local, the golf-course or fishing 
For very many plants, a winter rest is essential for their continued development and success but, in the greenhouse, some plants that would naturally be growing almost all year round can also be kept dormant over the winter to economize on heating and lighting. How you treat plants as they approach their winter rest is extremely important. So, too, is the way you treat them

Just how useful depends largely on the greenhouse design, but with a little planning most of these often-neglected areas can be made very productive. Never be tempted to use the space under the staging in your greenhouse as 
Early bulbs can bring added colour to your home in winter. Order them in early autumn (August), to plant in bowls or pots indoors or in the greenhouse in mid autumn (September). Bulbs, corms and tubers that are generally grown in pots for early flowering are hyacinths, daffodils (narcissi), tulips, crocuses and cyclamen. Choosing your bulbs Always buy top-size bulbs for 
Hanging baskets, suspended from the roof of your greenhouse, are an excellent answer to the eternal roblem of drindling shelf space in the greenhouse. And, in fact, many plants are seen at their best displayed in this way.
Do make sure, first of all, that your greenhouse roof will support the weight of your hanging baskets; remember that, after watering, a container may be 
Too many people deprive themselves of the pleasure of owning a greenhouse by thinking of the cost of heating it during the winter. But you can enjoy enormous benefits from protected cultivation without providing any additional heat. There is a wide range of plants that need only shelter from wind, excessive rain, frost or extreme cold, to give finer results and earlier crops
