How long does it take for the cuttings of bougainvillea to sprout and grow roots (how to manage them after cuttings to make them take root quickly)

First, the time for cutting bougainvillea:

In the south, the only month that is not suitable for cuttings is September of the lunar calendar. In the remaining 300 days, as long as the temperature is above 18 degrees Celsius, cuttings can be taken. However, the best time is spring when the temperature is above 18 degrees Celsius, which is the best time for cuttings.

Sometimes even the cuts that fall to the ground can grow roots and become seedlings. Spring cuttings take about 10 days to germinate and 20 days to grow roots . This is the fastest time for rooting.

Second, bougainvillea cuttings:

The cuttings also affect the rooting efficiency. Cuttings should not be too tender, as they are easy to dry out. Cuttings should not be too old, as cell activity is reduced, and rooting is slow or less. Usually, the best cuttings are 2 to 3 years old .

The branches will take root faster if they are treated as follows:

1. The diameter of the cuttings is about 0.5 to 1.5 cm. The length of the pruning is about 15 to 25 cm.

2. Use a utility knife to trim the cuttings neatly without burrs. The wound should be trimmed at a 45° angle.

3. Remember to spray the branches with carbendazim to disinfect and sterilize the cortex before cuttings.

4. Before grafting, soak the branches in a rooting agent containing "naphthaleneacetic acid" for about 3 hours.

Third, the planting material for bougainvillea cuttings:

The best planting material for cuttings of bougainvillea is freshwater river sand, and it is pure river sand. River sand is clean and sterile, loose and highly breathable, has good drainage, and absorbs and dissipates heat quickly, which is most conducive to the rooting of cuttings of bougainvillea.

Without considering the cost, it is best to use Akadama soil and river sand for cuttings.

Third, watering method:

The planting material for bougainvillea cuttings also needs to alternate between dry and wet. If the river sand is moist for a long time, it will cause the cutting branches to peel off, and roots will not grow in the peeled parts.

When watering, use your fingers to dig about 3 cm into the branches. When it is dry, water it thoroughly. When it is wet, just spray it to wet the branches, no need to water. After cutting, you can spray the branches 3 to 5 times a day.

Fourth, make a simple maintenance greenhouse:

Bougainvillea takes root and sprouts best when the humidity reaches 60% and the temperature reaches 25 degrees Celsius.

After the bougainvillea has been grafted, we can insert bamboo poles about 60 cm in height around the flowerpot, and then put plastic bags or plastic films on the bamboo poles to form a small greenhouse to retain moisture and heat so that the bougainvillea can grow roots as quickly as possible.
