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.
I just heard that it has been the windiest May on record since they started taking records. And even yet as i look out my office window i can see that the weather still has not really settled as much as one would expect for this time of year.
Never the less, listening to the weather forecast this morning it appears that things might be looking up coming into next week.
So why do i need to worry about my greenhouse if its windy outside. Well hear is a prime example.
Before looking into getting a greenhouse remember to think carefully about its location, its use, and its strength. If you take glasshouses as an example to highlight the importance of this. Say a 6′ x 8′ aluminium finish with horticultural glass. It may cost between €500 and €650 depending on the brand. Sounds like a bargin, but normally glasshouses in this price range are designed for very sheltered gardens. If its located in a windy garden, then it may end up like the glasshouse in the photo. Although it was a cheap buy, its an expensive loss.
So shop around, view the products where possible and remember a cheap bargain is not always the best buy.
