Cutting method of paulownia

Branch cutting

The cultivation soil can use fine sand or perlite, choose the container with holes at the bottom of the basin, keep the soil loose and breathable, choose the branches and buds with 4 leaves, cut off the branches and buds with fire-roasted scissors, put the branches and buds into the pit, cover the soil, pay attention to shade, keep the temperature at 18 ℃-20 ℃, and germinate in half a month.

Leaf cuttings

The flower of the plant lags behind, so choose the more robust leaves, together with the petiole, and pick them from the base. Cut off the leaves, then insert the petiole obliquely into the mixture of perlite and vermiculite, leave 2/3 of the leaves on the soil surface, covered with glass, placed in a cool place, heat preservation and moisturizing, seedlings can grow in about 20 days, and can be transplanted into flowers.

Bud insertion

It is usually carried out when it germinates in spring, and the new buds are selected to grow to 4ml / 6cm. The new buds are broken off from the base and inserted into the sand bed to maintain a certain humidity and temperature. after a long period of cultivation, they can blossom in June and July of the following year.

The method of Cuttage Propagation of paulownia

Cutting propagation time of paulownia
