Why Potted Wax Begonias Do Not Bloom and How to Care for Them

There are many varieties of begonia, and among them, the wax begonia (four seasons begonia) is one of the more common and widely grown varieties in daily life. Why does everyone like the wax begonia? Because its greatest feature is that it blooms in all four seasons, and its colors are bright and beautiful, with clusters of blossoms and a natural fragrance. Whether planted outdoors or indoors, it is a good decorative plant. It is especially often seen in flower beds in some parks or residential communities. Wax begonias can be planted in spring and autumn, and many gardening enthusiasts want to grow a pot themselves. Today let us learn together how to grow potted wax begonias? What are the reasons they do not bloom?

I. How to grow potted wax begonias?

1. Growing environment

To grow wax begonias well, we must first understand their growing environment. Wax begonias like to grow in warm, humid environments, and they are not tolerant of high temperatures or low temperatures, so care must be proper during these two seasons. For example, during the low-temperature season, give them sufficient light, and during the high-temperature season, cool them down appropriately and provide shade.

2. Appropriate fertilization

Fertilizing also requires skill. Generally, we apply additional fertilizer at the right time according to the leaf color and growth condition of the whole wax begonia plant. The principle is usually frequent but light fertilization, because fertilizer that is too concentrated will burn the roots, causing the leaves to turn yellow and scorch, and in severe cases causing the whole plant to die. Wax begonias generally grow slowly in summer and winter, so fertilizer must be reduced or not applied at all to prevent rot disease.

To make the wax begonia's flowers even more beautiful, we can apply a certain amount of potassium fertilizer and phosphorus fertilizer before the flowering period.

3. Watering at the right time

During the growing period of wax begonias, water should be applied appropriately according to the growth condition of the whole plant and specific temperature changes. When dry, water thoroughly; when not dry, do not water. In winter, when temperatures are low, try to keep the potting soil dry and water less. If watering is needed, generally choose the afternoon when the sunlight is warmer. In summer, when temperatures are too high, the plant is in a semi-dormant period and also does not need much water. If watering, choose the early morning or evening when temperatures are lower, which is more beneficial to plant growth.

4. Pinching

To make wax begonias bloom beautifully and attractively, pinching is an essential step. Generally, after the flowers fade, be sure to prune and pinch promptly to encourage the plant to branch.

5. Summer and winter care

As mentioned earlier, summer and winter are the semi-dormant or dormant periods for wax begonias, when they grow relatively slowly, but they still need careful care. In summer, avoid direct exposure to strong sun, provide appropriate shade and cooling, and decide watering and fertilizing according to the situation, so as to avoid excessive water causing root rot and excessive fertilizer causing rot disease. If the winter temperature is below 10°C, move them indoors for care, with appropriate watering and fertilizing.

6. Pest and disease control

Wax begonias are prone to diseases and pests such as leaf spot disease, aphids, red spider mites, and leaf-rolling moths. We must spot them in the early stages of onset and control them promptly so that they do not affect the whole wax begonia plant.

II. Reasons wax begonias do not bloom

1. Insufficient light in spring and winter

Many people keep wax begonias indoors, but if there is not enough light and they are often in a dark environment, they will not produce flower buds and naturally will not bloom.

So when there is less sunlight in spring and winter, as long as the sun comes out, put them on the balcony or in the yard to bask in the sun.

2. Overwatering in summer

Overwatering can cause root rot, and root rot will affect the growth of the whole plant, so naturally it will not bloom.

3. Improper pruning in autumn

Wax begonias need relatively more nutrients in autumn. At this time, the branches and leaves are lush but are not pruned in time, so the leaves absorb most of the nutrients. The flowering period also requires a large amount of nutrients, and since the nutrients are all absorbed by the leaves, the plant does not bloom.

Summary: To make wax begonias bloom beautifully, we must master factors such as light, fertilization, watering, and pruning, and no small detail can go wrong.
