When the keel is small, you need to top it. Then let it develop three or four side branches, and then the side branches will branch. The growth of this kind of keel will be symmetrical and beautiful.
Keels such as cacti like sunlight, and they can grow stronger under sufficient sunlight. But it is very hot in summer, so it is necessary to shade the keel to avoid the sun exposure. Try to put it in the sun in other seasons, so that the branches of the keel will grow greener and more evenly.

Cologne is drought-resistant, so it should be watered properly. Water can be watered once every five days in summer. If the basin soil is too wet for a long time, it will cause rotten roots. During the winter dormancy period of 1-2 months, watering once will not dry up.

Matters needing attention in keel planting
1, the keel does not require high culture soil, but it needs to be mixed with a certain amount of river sand. If some base fertilizer is mixed in the pot, it can grow well without topdressing during the growing period, and granular compound fertilizer is the best fertilizer.
The lowest temperature in winter is 5 degrees Celsius. Keels are propagated by cutting. From May to September, cut the top 5cm-6cm of the mother plant as cuttings, dry it in the shade for a week, and then cut it after the incision is fully dried, which is easy to take root.
