Start with good potting soil

Good potting soil is indispensable if you want to enjoy your plants for a long time. For most plants you can just use universal potting soil, but for some varieties potting soil with a specific composition is better (such as hydrangea soil).

How much potting soil do you need?

Are you going to fill pots or containers with plants, flowers or bulbs? Then make sure that your pot or container is the right size. In a pot that is too small, there is often not enough room for the plant to grow. If the pot is too big, the water will drain too quickly and the plant may dry out. If you are going to plant flower bulbs , make sure the pot is deep enough and ensure good drainage.

Below you can see exactly how much potting soil you need for the pot you have chosen. That way you never have too much – or too little – potting soil at home. Never fill a pot completely to the brim, so you have room for fertilization .

The actual filling of the pots

  • Flower boxes, pots and tubs for outside must have drainage holes in the bottom. So see if your flower box has this and otherwise drill holes in it.
  • To prevent the drainage holes from clogging and for good water management, first add a layer of 3-6 cm Hydro Granules to the bottom. On top of the hydro grains, apply a layer of fresh potting soil.
  • Immerse dry (garden) plants in water and then place the plant in the pot. Fill the pot to the brim with potting soil and then press it loosely. Then give enough water.

Tips for a beautifully filled flower pot

  • Planting a flower pot is not difficult at all. The most important thing is to think carefully in advance about the plants you choose and the flower colors. That way you make a nice arrangement that you can enjoy all summer.
  • Consider which color tone you want to use, such as blue-white or blue-gray. Choose only one, otherwise it will quickly become too busy.
  • Choose one leaf plant, for example a Helichrysum (curry plant) or Senecio (silver leaf) and plant it in the center.
  • Place flowering plants around it in three varieties. For example, choose Surfinia, Dichondra or Verbena or other bedding.
  • Do not put too many new plants in the container, because they will still grow. Most annuals have a planting distance of about 25 cm.
