Polytunnels - cleaning, wood treatment, ventilation etc.

[Russel Sprout]

Hi all

It's a bit late to be getting to round sorting my polytunnel, but better late than never as they say I've not used it before as I moved into the house last year. And I'm totally new to ploytunnels.

1. Cleaning. I have some Agralan Citrox for cleaning but the instructions are sparse. Does anyone know how to use it? Should it be used like a normal soap and then rinsed off? Or sprayed on and left to do it's thing?

2. Should I use the Citrox for the outside of the PT as well?

3. I need to re-treat the timber sections... Can anyone recommend a suitable product to use? Seems the wood gets quite dry on the inside, so I need to bear that in mind along with the weatherproofing.

4. Might be a silly question, but do gaps matter? The doors are quite ill fitting, so there's reasonable sized gaps around them. Is that an issue? Is it a case of the more air tight the better?

Many thanks

air movement is generally good for plants as long as it's not a gale.

I use ranch aka fence paint for outside wood as its cheap and does a decent job - a 5L tub will do a load of wood don't try to store the tub over winter where it can get frosted though

Can't help with your other queries - I'm too lazy to clean anything much in the garden - occasionally the plastic pots get a scrub, if I can be bothered.

Happy gardening :-)

I just use water and a soft brush for cleaning. I don’t treat the timber, and I just clean it.
I’ve gaps round the doors of my polytunnel.
