Watering

I have just made up some baskets and when mixing the compost I usually add some soil as I find it holds water better, especially with peat free composts, most of the baskets are filled with recycled compost which will have some soil in it, but I had posted in another thread I would be using soil for moisture retention and someone (my apologies for not remembering who, but did remember their tip) mentioned using seaweed for this, so I have made up 2 baskets using clean compost with seaweed mixed through it, so will be keeping a check on how they perform
