The underground stems of Hawaiian coconuts will produce new branches during their growth. The method of dividing these newly sprouted branches from the mother plant and planting them separately is the method of branch propagation. This method is usually suitable for growing new branches around April.
Divide plant should take out plant from flowerpot first, shake off the soil that adheres to, observe the gap between roots carefully, use tool to divide plant along the gap of root..
Each coconut can't be divided too much. It's better to divide into 2-3 plants. In the process of segmentation, the plants should be evenly divided so that the size of the separated plants is the same. At the same time, pay attention to observe the distribution of each part of the root and branch, so that the whole separated plant remains symmetrical, in order to increase the survival rate, at the same time, pay attention to protect the root, avoid the damage of the plant root can not survive.
After separation, it is necessary to prune, remove rotten roots and leaves of new plants, and then apply sulfur powder and other chemicals on the incision to disinfect, so as to avoid bacterial infection. Finally, the plants which had been detoxified were planted separately.
The advantages of ramet propagation are high survival rate and fast seedling formation. The disadvantages are limited number of propagation and large amount of operation, so it is not suitable for large-scale propagation.
Hawaiian coconut will produce offspring seeds in the process of growth. The way to collect these seeds and sow them is to sow them. This method is generally suitable for plants from September to October after seed ripening.
The seeds of Hawaiian coconut should be collected first, and then buried in the soil of seedling basin. Sow the seeds in time. Don't leave them outside for too long. Basin soil should have fertility and keep loose, had better disinfect ahead of time..
Special attention should be paid to the temperature when sowing. When the temperature reaches 25 ℃, most of the new seedlings can germinate normally. When the temperature is lower than 20 ℃, no new seedlings can germinate.
The sprouting period of new seedlings is longer, generally three to four months, during which winter cold prevention should be paid attention to. New seedlings should pay attention to add urea and other nutrients to ensure the healthy growth of new seedlings.
Grow to about 20 or 30 cm after you can choose healthy, fast growth of new seedlings into a new pot.
The advantage of seed propagation is that it can propagate in large numbers, but the disadvantage is that the seedlings just grow up, and it will take a while to grow into ornamental plants.
