Product description:

The easy way to home jungle! Osmocote Substral is a long-lasting fertilizer in the form of flower and house plant plugs. The unique formula of the polymer coating causes the fertilizer to gradually be released into the soil under the influence of moisture and temperature of the substrate. The plant therefore receives a small dose of nutrients that is tailored to its needs. Thanks to this, the Osmocote fertilizer works for a very long time, up to 6 months - one fertilization per season is enough, without the risk of over-fertilization. The fertilizer is very efficient, plants can use up to 85% of nutrients compared to ordinary granules, where it is only 25%. Properly selected ingredients of the Osmocote fertilizer meet the plant requirements and guarantee visible results in the season. Plants grow wonderfully, are less susceptible to diseases and insects, and withstand drought better.



Use plugs once every 6 months.

Bury the plug 5 cm below the ground, at an equal distance from the roots and the edge of the pot. When transplanting plants, use SUBSTRAL Green Plants.
