The pot culture of palm bamboo usually changes the pot every two years. During this period, it is very important to ensure that the pot soil has enough nutrients to supply the growth of palm bamboo. When changing pots every year, add cake fertilizer into the soil, stir evenly, or add a certain amount of slow-release fertilizer. If the base fertilizer is well applied, the fertilization cycle can be extended properly in the later maintenance process.
Generally, it is required to apply fertilizer once every 15-20 days, root irrigation or granular fertilizer. Spray foliar fertilizer once every 10-15 days, and use the two methods alternately.
According to the principle of applying a small amount of fertilizer many times and thin fertilizer frequently, the organic fertilizer and high-efficient P-K fertilizer were selected, and the trace elements were supplemented properly. 15-20 days, suitable for one-time corrosion of cake fertilizer or rapeseed cake fertilizer, 20-30g per pot, a small amount of ferrous sulfate 5g.
It is also suitable to spray 800 times of the aqueous solution of GMS organic humic acid active liquid fertilizer on the leaves every 10-15 days to spray all the leaves evenly, so as to start dripping water.
Palm bamboo grows rapidly, has more leaves and needs more water. During the growth period, it is necessary to ensure sufficient water, keep the basin soil relatively wet, do not seriously lack water, or the basin soil is dry and cracked. Once the root is damaged, it needs a long time to recover. Generally, water once every 2-3 days, about 2-3kg for each basin, and let the water fully soak the basin soil without water.
The transpiration of palm bamboo leaves is strong. In summer high temperature season and spring winter gale weather, it is necessary to pay attention to timely water supply. It is suitable to spray water on the surface of the leaves and evenly wet all the leaves with water drops dropping down.
And improve the air humidity around the potted palm bamboo to prevent the leaves from being damaged in dry and dry weather. Spray water at least 2-3 times a day.
In a word, during the growth period from May to September, palm bamboo should be watered more to keep the soil moist. It's better to be wet than dry, but it can't accumulate water or it will easily rot.
