I have a large Crassula that I keep on the balcony of the condominium staircase in front of the French window. In summer the upper half of the door remains open. and the sunlight arrives from the morning until around 14.00. Unfortunately, starting in June, the plant begins to lose the leaves that are still abundant green and completely healthy. I have the doubt that I have watered it too much but I'm not sure ... I don't know what to do. What do you recommend? Thanks
the genus crassula has dozens of species of succulent plants, originating in southern Africa; the most widespread species in the apartment are crassula arborescens and crassula ovata; these are plants that produce a sort of fleshy, well-branched stem, which bears large spatula-like leaves, of a bright green color. At the end of winter, if cultivated in a suitable place, the crassula are filled with small star-shaped flowers, of a white color, not very showy if taken individually, but surely the plant, completely full of tiny flowers, becomes decidedly beautiful. The success of crassulae as houseplants is due to the fact that they are plants that show low cultivation demands, even in the midst of their vegetative development. During the cold months, it is not necessary to water or treat the plants in any way; the position in which you keep your crassula is perfect, as it can enjoy a cool climate during the cold months. At the arrival of spring it is good to start watering again, but surely it is always good to water once less, rather than once too often; therefore, avoid watering excessively: the loss of the sheets and is often a symptom of excessive watering. Wet the soil only when it is dry and dry. The amount of sunlight your plant receives seems to be the right one; perhaps the problem may also be linked to poor ventilation: spent the crassula, in conditions of poor ventilation, they are attacked by scale insects, which nestle at the base of foliage. Since your crassula is grown in pots, the best thing would be to use a systemic insecticide, which means that it enters the plant in a circle; there are commercially available insecticide tablets, to be inserted into the earth, which melt every time you water; look for those that expressly have anticoccidic action.
