Fertiliser sticks for flowering plants, 30 pcs, Greenworld

Fertiliser sticks for flowering plants are the simplest way to feed a houseplant: you push a stick into the pot compost, and every time you water, a little food dissolves out of it and reaches the roots. No measuring, no mixing, no bottles, and overdosing is difficult.

One stick feeds a plant for about three months. That suits people who forget to feed, and plants that a neighbour waters while you are on holiday. The nutrients are released evenly, without the sharp peaks and troughs that come with occasional liquid feeding.

The pack contains 30 sticks. Made by Greenworld.
