MILF THREE-WAY – completely unpretentious succulent. Care and breeding at home


Indoor succulent plant Euphorbia Triangular in the first years of life in the apartment needs an annual transplant, then it is advisable to transplant it into a new pot when necessary, when the roots completely occupy the previous one.

The size of the new pot should be 3-4 cm larger in diameter and height than the old one. Since the bush grows rapidly upwards and its crown is significantly superior in weight to the root system, the pots are often turned over. To prevent this, a layer of large heavy stones can be laid at the bottom, sprinkled with fine pebbles or crushed brick.Pebbles will increase the stability of the flowerpot and play the role of drainage.

To transplant flowers, you can take the soil ready, with a neutral reaction. Many experienced flower growers prefer to prepare the soil on their own. Take equal parts:

  • soddy soil;
  • leafy soil;
  • sand;
  • peat.

Then the plant is taken out of the old flowerpot, thoroughly cleans the roots of soil residues, put into a new container and sprinkled with earth. The transplant is done very carefully so as not to damage the young roots. After that, you can water the flower a little.
