I've never heard of these before, but I saw them in Poundstretcher the other day, £2.50 for a pack of 2, so I thought I would give them a go.
The idea is that you fill your hanging baskets almost to the top
and then place the disks in position. I decided that rather than have one blue basket and one yellow basket I would have two mixed baskets, so I cut the disks into quarters and placed them thus.
You then cover them, water, place in the greenhouse or somewhere warm, and wait. I guess if you come back in early June, I might be able to show you the end results hanging in my garden.
I am so desperate for it to warm up a bit, as these all need sowing, but its just too cold right now.
It is dry though, so I may venture outside this afternoon and do a bit more preparation on my second veg raised bed.
