Polytunnel’s should be cleaned at least once a year, maybe more if your Polytunnel is nearer trees as it will probably have algae forming on the outside and debris from the trees falling onto it. There are different ways in which to clean your tunnel. Here are a few helpful tips :-
If you get a bucket of warm water and add a small drop of washing up liquid, you will then be able to use a soft brush to clean the tunnel, for the bits you cannot reach get an old bed sheet and with a person each side of the tunnel gently go along the tunnel. Be careful not to do anything that will scratch the cover as this will reduce the light transparency.
Hi all just a quick reminder in this cold weather. You might not be in mood for entering into the garden, however if you’re the proud owner of a greenhouse i would recommend it, Why? you might ask.
Well certainly for those in the east who are encountering the most snow fall at present they will find that a certain amount is building up on the roof of your greenhouse. At first glance it may seem harmless; however it might be worth noting that potentially it could do more damage than you might think.
For example, the weight of freshly fallen snow is approximately 100 – 150 kg / cubic meters. And once it has fallen on a solid surface the effect of compaction due to its own weight the wind and other additional factors rapidly increases the weight of the snow.
To put it in context if the roof of your greenhouse had a surface area of 16m squared, and we received 50mm of snow which is about two inches, you would have .9 of a cubic meter of snow on your roof. This equates to approximately 80 – 100kgs. If this snow freezes the weight on the roof increases. Depending on the model of greenhouse that you own, it’s worth noting this may affect the structure of the greenhouse.
To avoid any damage or the possibility of a complete collapse of the greenhouse I would recommend that you clear it of snow as it builds up. Please note that this is perfect excuse for going out to throw snow balls, so thankfully it’s not all bad news.
