Euphorbia atrispina: Answer: the diseases of the succulents


Dear Elena,
euphorbia atrispina is a succulent native to Africa, where it reaches the size of a beautiful shrub, up to a meter high and very wide. It is a very beautiful plant, with many branches, sharp thorns and small leaves at the apex of the branches; periodically it also tends to produce small yellow or red claws, which make it even more pleasant. It is a succulent quite easy to cultivate, which in winter can find a place in a cold greenhouse, while in spring and summer it moves outdoors, to a place where it receives a little direct sunlight, but only in the most hours. fresh of the day, while in the rest of the day it loves the bright half-shade. Over the years these plants become very large even if grown in pots.
From what you say, I fear that your plant has been hit by a fungus of some kind, starting from the collar or the roots; if you do not quickly tamper with this type of parasite, it will tend to damage the entire plant, causing it to die. Unfortunately, the quickest and most certain method is to cut all the diseased parts, eliminating them and keeping only the healthy, firm and compact parts of the stem. If the disease has affected only a few branches, remove them completely, at the base. If, on the other hand, the disease has affected the central stem, you will need to take cuttings from your plant, how big it depends on where the fungus is positioned: cut off any parts that are soggy, smudged, or dark (even looking at the stem inside), with a sharp knife, thoroughly cleaning the knife with alcohol after each cut. The cuttings thus obtained will be left to dry for a couple of days, and then buried. For these euphorbias a good melted and very well drained soil is used. Remember that these plants need watering when temperatures are above 15-18 ° C, and should be left without water when temperatures are lowered, but also when the days get shorter. The presence of rottenness denounces excesses of watering, or an excessive frequency, or a poorly drained soil, which remains wet for a long time, without being able to dry completely.
