Aloe belongs to the succulents, the Asphodel family. Today, science knows about more than 500 species of plants. It can be tree-like, shrubby, grassy or leafy. The leaves are thick, fleshy, form the trunk of a flower. Their length can reach 60 cm. The peculiarity of succulents is that they can accumulate a large amount of water in themselves.

As soon as there is room for the roots, the problem of dried tips will disappear.
Note! Before transplanting, the plant is not recommended to be watered for 3 days.
Stains on the leaves
Stains on aloe leaves can appear for several reasons. For example, with drought, brown or red spots of irregular shape form on the leaves. The same reaction explains the fact why aloe leaves turn yellow. In these cases, the number of irrigations needs to be increased; it is even better to irrigate not into the ground, but into the pan. In this way, you can prevent both an excess of moisture and its lack.
If dark, black spots began to appear on the leaves, it means that the plant attacked a fungal disease. These spots may be soft to the touch. As soon as the slightest reddening of the leaf becomes noticeable, the flower is transferred to a well-ventilated room and the leaves are treated with fungicides.
