What fertilizer should be used to make bougainvillea bloom more

1. What fertilizer to use

If you want Bougainvillea to bloom, you need to apply some phosphorus and potassium fertilizers before it blooms. The amount of nitrogen fertilizer should be controlled. If you apply too much, it will not bloom. You can apply some potassium dihydrogen phosphate to it, so that it can bloom better after sufficient nutrients. If there is a lack of phosphorus, the flower buds of the plant will be difficult to form and it will not bloom. When the plant grows flower buds, stop fertilizing it, and do not fertilize it during the flowering period. However, do not apply concentrated fertilizer to it to prevent fertilizer damage.

2. Which month to apply fertilizer

Bougainvillea needs to be fertilized during its growth period. It is generally not necessary to fertilize it in winter. It is usually fertilized regularly in spring, summer and autumn. In April-July, liquid fertilizer is mostly applied to it, which helps the plant grow more vigorously. From around August, phosphorus and potassium fertilizers should be applied.

3. Notes

1. If the temperature can be maintained at normal level during the winter and the plant is still in a growth state, you can fertilize it appropriately.

2. If the soil is dry when applying fertilizer, you can apply fertilizer to it. If the soil is in a moist state, do not apply fertilizer to it.

How to take cuttings of bougainvillea

1. Branch picking

Choose 10 to 15 cm semi-lignified branches, which are easier to root. When cutting, make the scissors and the branches at a 45-degree angle. Remove excess leaves after cutting to prevent nutrient consumption. Use scissors to trim the roots of the branches to promote wound healing and facilitate rooting.

2. Soak in rooting water

Soak the trimmed cuttings in rooting water diluted with clean water for one to two hours. After soaking, take them out and place them in a cool and ventilated place to dry.

3. Choose pot and soil

Choose a clay pot with drainage holes and good air permeability, and a larger diameter is best. The cutting medium is generally a mixture of river sand, vermiculite, perlite, plain sandy soil, peat soil, rotten moss, husk ash, sawdust, flower mud, etc. If the material is insufficient, you can choose a mixture of plain sand and perlite, or you can use the nutrient soil that has been prepared on the market.

4. Put it in the basin

After putting the nutrient soil into the pot, compact it with a shovel, poke a few holes two fingers deep with chopsticks, insert the branches and compact them with your fingers, then water it.

5. Maintenance

After the cuttings are completed, place them in diffuse light at 18 to 30 degrees for 20 days to a month to grow new roots. After the roots grow, normal maintenance is sufficient.

How long can the bougainvillea be exposed to the sun after changing the pot

1. How long can you bask in the sun after repotting?

After repotting, the roots of bougainvillea need to be slowed down. Generally, it takes about a week for it to slowly adapt. After adapting, it can be gradually exposed to the sun. Do not expose it to light after just repotting. Put it in a cool place, but ensure that there is a little ventilation. If it is exposed to the sun right after repotting, the plant will be very fragile and may die.

2. What to do if the roots are damaged by repotting?

During the repotting process, its root system may be damaged if you are not careful. If the root system is damaged, it needs to be disinfected. You can also apply some charcoal powder to it to avoid infection. In addition, it needs to be given time to acclimate after potting. As long as you pay more attention, it will not affect its growth. When acclimatizing, you need to temporarily postpone sun exposure and do not apply fertilizer to it. After it has adapted to the pot, it can be maintained normally.

3. Other matters needing attention

1. Soil selection: It is very important to choose suitable soil. It is recommended to use soil with good loosening ability. After preparation, it should be exposed to the sun, or disinfected with potassium permanganate.

2. Clean the roots: The soil on the roots must be cleaned off so that you can see the real growth and avoid missing the rotten roots. If the rotten roots are not cut off and the plant is potted directly, it is very likely to be infected during the acclimatization period.
