The soil is usually laid with a thickness of three to five centimeters. Since this handsome man is planted mainly in groups, his need for good root fertilizers also increases significantly. They are either applied directly under the roots, or simply dissolved in water. Also, when planting a wonderful plant, it is useful to add a small piece of peat or clay under its roots.

This green pet grows equally well on open areas, and being shaded by other plants. At twelve o'clock light day this aquatic handsome man has enough light with a power of 0.5 - 0.7 W / l.

As a rule, its stalks are first divided, and then the separated upper parts of the plants are transplanted to new sites. When cleaning aquariums, Mexican oak stalks often break - if they are not thrown away, then in the near future they will certainly give new specimens.
