Balcony flower fertilizer spikes from Substral®, available here in 3 x 7.5 g packages, provides a cheap and easy method of growing an abundant flower cascade of trailing petunias, fuchsias, petunias, begonias and other typical balcony flowering plants. One spike contains one dose of the EC NPK fertilizer that satisfies all nutritional requirements of flowering plants. This easy-to-apply plant food stands out with slow release and extended performance. One spike dissolves gradually over the course of nine months, providing the plants with small doses of micro- and macronutrients they need to grow healthily and bloom abundantly. Risk of overfertilization or leaf burn is therefore completely eliminated. Fertilizer spikes are a great solution for busy, forgetting and frequently travelling people.

The proce quoted here is valid for a 3-piece package of 7.5 g balcony flower fertilizer spikes. One spike is intended for one 10-cm pot. This is an original Substral® product.
