Fertilize balcony plants - when and how often?
Balcony plants are no scoffers, because their energy consumption is high. For a lavish floral and foliage dress, the consumed nutrients should be regularly balanced. The right time intervals are just as important as the fertilizer itself. This guide explains in a compact and practical way when and how often you fertilize your balcony plants properly.
Time window is open from spring to autumn
In the bed, plants can rely on the fact that hosts of industrious soil organisms provide for a continuous supply of nutrients. Balcony plants, on the other hand, have to be satisfied with the limited substrate volume in the box and bucket. In order to prevent deficiency symptoms, organic and mineral fertilizers regularly replenish the consumed reserves. When and how often you fertilize correctly, summarizes the following overview:
If perennials and winter hardy trees retreat in autumn, the time window for nutrient supply closes. Now, the associated growth spurt is actually detrimental, as it impairs frost resistance and challenges healthy wintering.
As an alternative to the weekly administration of liquid fertilizers, modern slow-release fertilizers cover the nutrient requirement for up to 6 months. These fertilizers are available as granules, cones, rods or balls and are inserted into the substrate. Once administered in spring, the balcony plants are protected against deficiency symptoms for the entire season.
After planting and substrate change, please take a fertilizer break
Substrates for balcony plants are usually pre-fertilized. Freshly planted or transplanted flowers, perennials and shrubs are well supplied with nutrients for the first 6 to 8 weeks. In order to avoid a harmful oversupply, the use of fertilizer only starts again when the supplies are consumed.
Tips
Have you turned your balcony into a snack? Then mineral fertilizers are taboo. An organic nutrient supply guarantees lush growth and carefree enjoyment of balcony vegetables. Just farm a worm farm on the balcony. Then, from spring to autumn, organic worm compost and rich worm tea are available as free fertilizers.
