Strawberries in the flower box transform the balcony into a snack garden. A bed is therefore not necessary to enjoy the aromatic fruits. Find out here which aspects have to be considered on the way to a rich strawberry harvest.

This is how a flower box for strawberries should be

As heavy feeders, strawberries require a larger volume of soil, from which they obtain nutrients and water. A flower box (€16.99) should have the following properties so that strawberry plants feel at home in it:

  • Height: 18-20cm
  • Width: 22-25cm
  • Length: 80-100cm

Ideally, the flower box has an irrigation system (€32.95) in the form of a separate level below the ground. Here the very thirsty strawberry plants can help themselves. A water level indicator shows when the supply needs to be refilled. At least there should be several openings in the bottom so that excess water can drain off.

Checklist for proper planting and care

The key factors for successfully cultivating strawberries in flower boxes are briefly and concisely specified in the following checklist:

  • a sunny, well-ventilated location
  • nutritious, slightly acidic compost-based substrate with loosening components such as perlite (€37.51) or sand
  • a drainage over the floor opening prevents waterlogging
  • Do not plant strawberry plants deeper than the heart bud
  • the planting distance is 20-30 centimetres
  • water regularly and fertilize organically
  • mulching with leaves, straw or bark mulch keeps the soil warm and moist

If you would like to harvest your strawberries while standing, plant them in a flower box with an integrated trellis. Since the tendrils do not have attachment organs for independent climbing, they are regularly attached to their trellis.

Take care when harvesting

Proper harvesting of strawberries requires a little attention. In normal years, the strawberry season starts in May. Harvest only fully colored fruit without a greenish-white edge. Snap off the fruit stalk along with the green leaves.

tips and tricks

Strawberries can overwinter in the window box because they are frost-tolerant. After harvesting, the leaves and tendrils are cut off, except for the heart bud. Standing in front of the south wall of the house on a wooden or styrofoam slab, covered with fir fronds and brushwood, the plants survive the winter here. On frost-free days, the strawberry plants get a sip of water.
