:)Hi, We got ourselves a green house last Autumn. I put weed suppressing matting down and then covered with gravel. There are a line on slabs down the middle as a path. I have run a watering system in from the back corner. The results have been quiet good. I over wintered several tender plants and started up the spring and summer sowing. I grew tomatoes in grow bags and chillies and cucumbers in pots. Which all did very well. The down side was ants trying to make nests in the grow bags and more recently red spider mite.  I am wondering about taking up the gravel and concreting in a base as I am worried that I will be fore ever plagued by the spider mites. Any ideas |

Hi there Itranter! Red Spider mite is a PAIN. I have it on my houseplants too. I think increasing humidity is an accepted way to reduce the infestation. Easier in a GH than a conservatory! They tend to increase in the summer months mostly so a really good spray of everything now might help - the colder temperatures will help too now. There are biological controls which can be used for next season. I usually end up chucking out the really badly affected houseplants... Personally I don't think changing your arrangements will make a lot of difference. Hope that helps. Here's a link: www.gardenersworld.com/how-to/problem-solving/red-spider-mite/ |

I agree, red spider mite like very dry conditions. Just hose hown the greenhouse regularly and they will disappear.

Laying concrete will not rid you of spider mite, they are carried on the breeze, your best bet is to make the environment uncomfortable for them, they like dry heat, raise the humidity by wetting the gravel well when you water.

NB Just wanted to add - if you do hose everything down - make sure you get the underneath of all the leaves and stems good and soaked - sometimes those little tucked away places get missed - and that's where they hide.........

Hiya Itranter and welcome.
As you can imagine red spider mite is one of the real problems in a cactus house as it has to be dry but this last summer is the first I can remember for some time that has been RSM free.
I am sorry to say that I do use chemical sprays against this.

Thanks for the advice, I will keep the greenhouse set up as it is. Next year I will order some of those biological controls to deal with the Red Spider Mites. I was worried about getting the greenhouse too [glow=red,2,300]humid[/glow] as it would encorage tomatoe blight and the like.

Isn't it cruel to keep your cats in the greenhouse?
