With spring well under way, you may be considering buying a greenhouse, Andy Taylor tells you how this will increase your chances of successfully growing a wider variety of plants over a longer period of time.
During the summer, the health of your greenhouse plants depends on adequate ventilation and shading. David Hall explains how the risk of overheating, dehydration and scorching can easily be averted.
Plants, like humans wilt in the heat, they need shade, water and effective air circulation. Few will survive in an enclosed greenhouse with a temperature over 80°F/27ºC.
Circulating air has a cooling effect on plants, and the easiest way to achieve adequate ventilation is to simply open the greenhouse door together with any vents. Whether to leave them fully or partially open overnight will depend on how much the temperature drops.
When buying a greenhouse, make sure there are enough vents (both roof and side louvres) and be careful not to underestimate the number of vents even a small greenhouse requires.
If the vents are for any reason not easy to open, think about buying a greenhouse that already has automatic vent openers. Many manufacturers will offer them as an optional extra, or they can be fitted to an existing greenhouse..
Auto openers are also very useful if you are away from home for any extended period. On holiday you can relax, safe in knowledge that the vents are opening each day and closing in the evening.
In the height of the summer the greenhouse will also need shading. As this reduces light transmission, shading needs to be kept at a minimum, just enough to regulate the temperature.
Shading can consist of internal or external blinds, or less expensive mesh. Placed outside, the shading will prevent heat being generated by passing through the glass but will be harder to fit and maintain.
Internal shading, including pegs to clip it in place, is available from Eden and will also fit other makes of greenhouse that have a recess in the glazing bar.
An alternative would be shading paint such as Bayer Coolglass that is mixed with water and applied by a brush or sprayer. At the end of the summer it is easily washed off.
Here in Birmingham, the weather has been as changeable as ever, very warm just before Easter followed by a cold spell only last week. During May the threat of further frost will largely pass and, with spring well under way, Robert Hall is in no doubt that this is going to be a busy month in the garden.
The weather forecast is for a sizzling summer and David Coton is already looking forward to preparing delicious barbecued food for his family and friends. Barbecues have become incredibly popular over recent years and here is David's guide on what to look out for when choosing one of these summer essentials.
Sheds of any kind are ubiquitous in the British garden and, due to their popularity, there are plenty to choose from. David Coton explores the basic considerations that need to be taken into account before purchasing one.
