Wilkinson has added two more Vital Earth lines to its 2010 offer.
The chain now stocks the Kayak growbag, as well as Chicken Poo fertiliser, which was launched at GLEE 2009.
The shape of the Kayak growbag (pictured) provides a reservoir to hold water more efficiently, aid absorption and allow deeper root growth.
The newly-added products will sit alongside Vital Earth multi-purpose packs, seed and cutting compost and tub and basket compost.
Rrps from £2.99.
