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.
At GLEE this year David Coton visited the VegTrug stand to find out how their specially designed space saving planters can encourage us to grow more of our own food without the use of pesticides.
Forest have been making high quality timber garden products for over half a century and at GLEE David Coton had the chance to see their brand new storage range that has recently been launched.
Everyone should be serious about encouraging wildlife, and whether you focus on pollinating bees, pest devouring birds or slug eating hedgehogs, David Hall has been looking at the products that Wildlife World design and manufacture to aid their conservation.
This week Robert Hall has been to the Glee Garden Trade show at the NEC in Birmingham and has reviewed the new Lotus Wheelie Bin Store; Metal Garages, Bicycle Store; Sheds and Workshops and more...
