How to pinch the hearts of Rieger begonias
A brief experience in the maintenance of green plants about how to pinch the hearts of Rieger begonias and the detailed explanation of the timing and precautions for pinching the hearts of Rieger begonias, let's learn about it together.
Rieger begonias do not easily grow lateral branches and are more tolerant to pruning. In the seedling stage, pinching can promote the sprouting and growth of lateral branches, making the plant's shape rounder and the flowers more beautiful. Rieger begonias prefer a warm and humid environment. They are perennial herbaceous plants of the Begoniaceae family, Begonia genus, and bloom from April to December, usually flowering in spring, and can bloom again in winter after growing in autumn. Next, let's talk about the method of pinching the hearts of Rieger begonias.
1. Pinching Time
Rieger begonia seedlings need to be pinched in time after growing 4 leaves, usually in the second week after transplanting the seedlings, and multiple times of pinching should be done during the growing season. Excessive flower bud tops should be removed during the flowering period to promote the sprouting of lateral branches, resulting in more flowers that are larger and more beautiful.
2. Pinching Seedlings
When the seedlings reach a certain height, the top bud should be removed. After pinching, 3 or 4 lateral branches can grow from the pinched position. When the seedling height reaches 10 centimeters, the plant can be cut back to 3 to 5 centimeters.
For seedlings that have been pinched for the first time, if there are many flower buds, it is appropriate to remove the top branches with multiple peduncles, so that the pinched position can sprout lateral buds, which is also more conducive to the growth of lateral buds. When the lateral branches grow to a certain length, a second pinching should be performed.
3. Maintenance After Pinching
Usually, when the temperature begins to drop in autumn, Rieger begonias will sprout new branches. At this time, pinching should be done, and plenty of water should be supplied to meet the plant's growth needs for water, along with sufficient direct sunlight to prevent the plant from growing too tall.
The optimal growth temperature for Rieger begonias is between 18 and 22°C. In an environment below 15°C or above 28°C, the plant grows poorly. If the ambient temperature drops below 10°C or exceeds 28°C, pinching should not be done, and the pinched plants should be placed in a warm environment for maintenance.
4. Precautions
In the growth process of Rieger begonias, try not to use plant growth regulators to prevent the plant from growing too tall. While pinching, it is also a good time to remove diseased and withered branches and leaves.
The above is a comprehensive introduction to how to pinch the hearts of Rieger begonias and the detailed explanation of the timing and maintenance precautions for pinching the hearts of Rieger begonias, hoping to bring some knowledge about green plants to green plant enthusiasts.
