The Euphorbia lactea “Cristata”, is of a tropical climate, is one of the few columnar Euphorbias that grow exceptionally well in very humid climates.

It can be kept in full sun or in semi-shade, but because of its motley shape, it is better to be protected from the strong sun in the hottest hours of the day.

It is a suitable substrate for this plant is a mixture formed by equal parts of clay and sand.

Euphorbia lactea “Cristata” in greenhouses, apparently rarely, are affected by fungal diseases.

It responds well to warmth, with its period of active growth in the last months of spring and summer.

For fertilization, diluted liquid fertilizer can be used in the irrigation water every 15 days or using organic fertilizer, the amount depends on the format.

These operations should be performed in the months of growth of the Euphorbia Milky (spring and summer) and in a less strong dose in autumn.

How to reproduce the Euphorbia

It is propagated by cuttings or stakes, while marbled and crested forms are difficult to grow on their roots, and are usually grafted for convenience in Euphorbia Canariensis or Resiniferous Euphorbia.

It is recommended to take Euphorbia cuttings in spring / summer, when the plant is growing so that they have a better chance of success.

The key is heat and good air circulation.

These cuts should be dipped in powdered hormones, although it is not essential.

Keep them there for a period of 3-4 weeks, before planting it.

Next, plant in a pot and do not water abundantly (keep slightly moist) until the cutting is well established.
