I could kick myself.. recently in a magazine or paper I saw an advert for some device that you fill with water, pop into the soil and gradually it lets out water to keep your plants (in this case tomato plants) Does anyone know what it is called and where I can get it from, (yet to check garden centres out).
Unfortunately I don't know anyone to ask to water our toms whilst we are away and think this gadget would help a bit to keep them alive!
Thanks in advance.
