How to make bougainvillea bloom all year round

1. Water control

Whether it blooms or not is related to the amount of water it gets. You can adjust the days when it blooms by controlling the amount of water. The prerequisite for water control is proper care at ordinary times. Normally, the plant should be watered alternately when it is dry and sometimes wet, and water should be controlled during the first 50 days of flowering.

At the beginning, you can stop watering it for three to five days, allowing its leaves and branches to droop slightly. Then sprinkle the crown with water in the afternoon. After fifteen days, it will return to normal, which can help its flower buds grow. When the flower buds grow out, you can apply fertilizer to help grow more flowers.

2. Shade

It likes sunlight and needs enough sunlight when growing. Even in very cold winter, it needs to be placed in a bright place. If it is given less sunlight, it will grow poorly, its branches will be thin, and the color of its leaves will be dull.

You can use a dark plastic bag, preferably black, to cover it during the first 50 days or so of its flowering period to prevent light from entering. Shading for about a month can also promote the formation of flower buds, but when it does not need to be shaded, be sure to ensure that it gets enough light.

3. Fertilizer control

It grows a lot of flowers, and the flowering period is also long, which must consume a lot of nutrients, so it is necessary to supplement enough fertilizers, especially phosphorus and potassium fertilizers. During its peak growth period, you can add fertilizer and water to it once a week. When flower buds appear in the leaf axils, you can apply more fertilizer. After the flowers bloom, you can add ferrous sulfate every three to five days.

From August to October, you can use fertilizer water instead of clean water. Don't use too much nitrogen fertilizer, otherwise it will grow wildly. You can also buy special growth regulators for it, so that its leaves will be greener, the crown will be denser, the flowers will be more colorful, and the flowering time can be increased by 20 to 30 days.

4. Pruning

After its flowers fade, you should change the pot in time and prune it appropriately according to its growth. Cut off the flower stalks to help the mother branches with flowers grow. Its outer branches have more flowers, so the inner branches can be pruned off to avoid wasting nutrients. It can also create a light-permeable and ventilated environment for it, helping it to increase the duration of flowering.
