How to Extend the Blooming Period of Roses in a Multi-season Spring
This article introduces some small gardening experiences on how to extend the blooming period of roses in a multi-season spring, which will surely be helpful to you. Let's learn about it together!
The rainy mode is about to start again. How are your roses doing? I saw our flower friends discussing yesterday, and the most talked-about topic was showing flowers and cutting flowers because it's going to rain again. So, when our roses are about to bloom and encounter rainy days, what should we do to extend the blooming period of the roses?
How to Extend the Blooming Period of Roses in a Multi-season Spring
To minimize the impact of rainy weather on the blooming period of roses and extend the duration of the blooming period, we need to focus on three key issues.
1. The Impact of Rain on Rose Buds and Blooms
Roses are particularly susceptible to rain during the blooming period because rainwater can scatter the petals of the roses, causing them to wilt prematurely. Rain can also easily break the branches of roses because the weight of rainwater accumulated on the flowers and leaves can put a lot of pressure on the branches. Once the branches can no longer support this weight, they may break or snap.
Sometimes, with the棒棒糖-style grafted roses, heavy rain can cause the branches to become too heavy and directly separate from the rootstock, resulting in irreversible damage. If the branches are broken, there is no chance of blooming, and both the flowers and buds will be sacrificed.
Therefore, during rainy days, it is recommended to take some protective measures for棒棒糖-style roses to prevent them from getting wet. If it's impossible to avoid rain, it's important to support the branches to prevent breakage.
2. The Impact of Diseases on the Blooming Period of Roses
The biggest harm to roses from rain is the occurrence of diseases. After continuous rain, rose flowers and colored buds are very susceptible to gray mold, leading to withered flowers and buds that fail to open properly. This is especially true for varieties with pom-pom flower shapes, such as Freedom Spirit and Luo Yi, which can easily rot on the branches after getting wet.
To deal with gray mold in roses, it is recommended that you spray a fungicide in advance before it rains to eliminate any potential pathogens. If possible, keep blooming roses and buds that have shown color away from the rain. For outdoor roses, you can set up a plastic film to block the rain, and for potted roses, using an umbrella is also an option.
If you have no choice but to let them get wet, it's important to spray fungicides as soon as the rain stops on cloudy days. In short, the medication should not stop, or else it's easy to end up with a "rotten mess."
3. The Number of Sustainable Blooming Buds
Most roses in spring have multiple flower buds. April's rain usually only washes away the first batch of buds, and we still have many backups. From this perspective, there's no need to be too regretful about the first batch of roses that got rained on. Instead, we should seize the opportunity to fertilize the roses more during rainy periods and allow the small buds to grow.
If all the buds can open normally, will you worry about not having enough flowers to look at?
Roses require a lot of nutrients during the blooming process and the growth of small buds. If fertilization is not timely after the roses bloom, the small buds can easily wither and fall off, naturally shortening the blooming period.
When it rains, we cannot apply water-soluble fertilizers to the roots, but we can apply fertilizers by spreading them. Whether it's roses planted in the ground or in pots, during rainy days, you can spread monopotassium phosphate fertilizer. This fertilizer will enter the soil with the rainwater and be absorbed by the plants, promoting the continuous growth of the buds. At the same time, the petals of the blooming flowers can also continue to grow. Cutting fresh flowers to put in a vase can be very fragrant, haha.
