Just look at these pictures of a trial done by a home gardener (not me!).
(Pictured left, above) Pansy plants at first potting up stage. Plants on the left hand side (of the tray) were watered in with Young Plant Food. (Pictured right, above) A few weeks later ….. and the difference is really beginning to show.
(Pictured left, above) Look at what a difference Young Plant Food has made to the root system on the treated plants!
(Pictured right, above) These plants were planted in a patio tub and watered in with Young Plant Food on 17th April.
(Pictured above) Look how quickly they’ve grown and established by 5th May!
