How it works

Step 1: Watering the plants

Thoroughly water the plants before planting. A better way is to dip the pot ball into a bucket of water until no more air bubbles rise.

Step 2: Preparing the trough

Cover the drainage holes in the trough with clay shards so that the soil does not run out of the pot along with the water.

Step 3: Filling the through

Fill 1/3rd of the trough with a peat-free flower soil. Carefully take the plants out of their pots and place them in your trough. Plant low and hanging varieties at the edge and higher varieties in the middle. After planting, the upper edge of the plant's root ball should be about 2 cm below the rim of the balcony trough, so that you can water the plant well. After all plants have been planted, fill the spaces between them with flower soil. Press it lightly.

Step 4: Watering

Water the plants gently but thoroughly. The water must drip out from the bottom of the trough; this indicates that you have poured enough.

Step 5: Care

  • Flower soils are usually pre-fertilized, so you only need to water the plants at first. Fertilizing starts only after a few weeks according to the information provided on the package. Depending on the plant variety, you may need to add fertilizers every week or every 2-3 weeks.
  • Watering the plants with Super Strength Seaweed Extract strengthens them and stimulates their growth.
  • Of course, plants need to be watered regularly, even when you go on a holiday! In the first four weeks, add Super Strength Seaweed Extract into the water once a week.
  • Regularly removing or cutting off withered flowers and leaves helps new flowers grow more quickly.
  • Liquid fertilizers such as Organic Multipurpose Plant Feed or Organic Multipurpose Plant Food are easy to sprinkle and have a long-term effect.

Extra tips for your balcony

  • You should start planting not before mid May when there is no risk of frost any more. Some plants cannot tolerate frost at all. In sheltered places however, you can start planting from mid April, depending on the weather.
  • Light-coloured pots don’t heat up as quickly as dark ones and therefore require less watering.
  • Automatic irrigation systems for balconies are also available in the market.
  • Choose bee-friendly plant varieties, such as snapdragon, marigold, aster amellus, harebell, common rockrose, catnip, woodland sage or wood betony. Many herbs, when they start flowering, are great insect magnets.
  • You can also place a salad plant between ornamental plants in the balcony trough, or even thyme or chives. More tips on growing vegetables, fruits and herbs on the balcony as well as plant portraits can be found here
