How to make Petunias bloom abundantly?
This article provides an introduction to the green plants and flowers that make Petunias bloom abundantly. Let's take a look with the editor!
If you want to grow a type of potted flower that is easy to care for, blooms profusely, and has a long blooming period, then Petunias are highly recommended. Petunias are very easy to make bloom abundantly and come in a variety of colors, making them very suitable for potting. So, how should you care for them to make Petunias bloom abundantly? Today, we will share the method to make Petunias bloom abundantly, hoping it will be helpful to you.
Methods to Make Petunias Bloom Abundantly
Petunias can be planted all year round, but if you want to easily achieve the effect of abundant blooming, it is recommended to sow seeds in autumn for seedlings or to purchase young seedlings in autumn for cultivation. Because in autumn and winter, as the temperature gradually decreases, the growth rate of Petunias will slow down, which is more conducive to nutrient accumulation. Due to slower growth, the internodes of Petunia branches are shorter, making the whole plant more compact.
Therefore, choosing the right timing for seedlings is very important. If sowing in spring, the growth rate of Petunias will be faster, the internodes will be longer, and the whole plant will appear more loose.
Of course, relying solely on adjusting the seedling time to achieve the effect of abundant blooming is not realistic. To make Petunias bloom abundantly, we need to meet the following three conditions.
1. -- Maintain Sufficient Light --
Petunias are sun-loving flowers. To make them grow strong with many branches, it is necessary to maintain sufficient light, with full sun in autumn and spring being ideal. If there is insufficient light, the branches of Petunias will grow weakly, internodes will become longer, naturally reducing plant compactness, and blooming will also decrease later.
2. -- Maintain Sufficient Fertilization and Watering --
If you want Petunias to bloom profusely in spring, fertilization is essential. Starting when the seedlings have 5-6 true leaves, it is recommended to persist in top dressing. Throughout the autumn and winter seasons, it is suggested to apply a compound fertilizer water or fermented soybean cake fertilizer water, or "Flower More No. 1" every 10 days or so.
In autumn and winter, the interval between watering is longer, and fertilizer can be added with each watering. If the temperature is above 5 degrees Celsius, Petunias are in a slow growth phase, and continuous top dressing should still be carried out. If the temperature is too low, it is recommended to place them in an indoor阳台 for faster growth, resulting in a larger crown when flowering in spring.
3. -- TopPING to Promote Branching --
Generally speaking, if you want a compact and full plant shape with abundant blooming in Petunias, topping to promote branching is necessary. However, the topping method is completely different for different varieties of Petunias. Here are examples using the common upright Petunias and trailing Petunias.
The branches of upright Petunias grow straight up. If these varieties are not topped during the growing period, they tend to have fewer branches and a taller plant height, which may be prone to falling over when flowering.
Therefore, upright Petunia varieties should be topped to promote branching when the seedlings reach about 5cm in height and no side branches are visible. If many side branches have already grown out, there is no need to top them at this time; observe the growth first, as some Petunia varieties naturally branch very well and can grow many branches even without topping in autumn and winter.
Upright Petunias usually undergo 2-4 rounds of topping in autumn and winter, depending on the growth of the seedlings. The first topping is on the main branch, and the second is on the side branches that grow out. Side branches can be topped again when they reach 3-5cm in height until the plant shape is full. Sometimes, if the plant shape is not yet full but flower buds have appeared, the flower buds can be pinched off along with the topping.
Trailing Petunias grow in a different direction from upright Petunias, and the topping is also different. The branches of trailing Petunias usually grow close to the pot surface in a sprawling manner. Topping trailing Petunias should generally wait until the side branches reach the edge of the pot before topping. Of course, early topping is also possible, depending on your requirements for the plant shape.
When topping, remove the top bud of the side branches to allow new side branches to grow, but be careful not to pinch the top bud of the central main branch, or else the trailing Petunias will look like a Mediterranean style when flowering. Trailing Petunias can also be topped multiple times on the side branches until the crown is full, and they will naturally bloom abundantly in spring.
