Why are potted roses easy to die?
Do you know these? Is it difficult to grow roses and why is it so easy for roses to turn yellow and wither in family plantings? Here is a comprehensive introduction to follow.
Yesterday, I saw a flower enthusiast say that they killed their rose again. The word "again" reveals so much bitterness. Are roses really that difficult to grow? Why are the roses in our potted plants so easy to die?
1. Is it difficult to grow roses?
In fact, it's not difficult to keep roses alive, but it's not easy to grow them well. In the past, in the countryside, many people had a couple of roses in front of their doors. They didn't manage them throughout the year, and they could still bloom continuously, even in the snow.
So why have roses become so difficult to grow now? Because most rose varieties are "imports." Nowadays, we like to grow European roses and Japanese roses, but we rarely plant our native rose varieties.
The roses widely planted in the countryside before were mostly ancient Chinese rose varieties, and even no one knew their names. But they were very tough and loved to bloom, such as the variety "Chilong Hanzhu," which is a very disease-resistant and diligent blooming ancient Chinese rose that even blooms in the snow.
European roses often have more diseases and pests due to the significant differences in their native environment compared to ours, so it's not that they can't survive, but they are far less resistant to diseases and pests than our ancient rose varieties, so they require more management, regular application of pesticides to prevent and control diseases and pests. If diseases and pests are not well controlled, roses will not be in good condition.
Roses from the island country, on the other hand, pursue novelty, and many varieties have unique and novel colors and shapes, which are very popular. However, they have poor disease resistance and weak growth, making them relatively more difficult to grow. However, some classic rose varieties from the island country still perform well, with good disease resistance and fast growth, such as the excellent variety "Zhencai 230," which has large flowers, blooms frequently, and is heat-resistant with good disease resistance and growth.
For新手 flower enthusiasts, it is recommended to choose some classic varieties that are tough and easy to grow. Some new or "beauty association" varieties are often not very friendly to beginners.
2. Why are potted roses easy to die?
You might say, "I've chosen only classic, tough varieties, why do they still always die?" Here we have to talk about the issue of pot and soil mix.
Many新手 flower enthusiasts like to use beautiful ceramic pots to grow flowers. But in fact, ceramic pots have very poor breathability, which is not friendly to roses that are intolerant to moisture and drought.
Ceramic pots not only have poor breathability in their own material but also have only one drainage hole, which can easily lead to clogging of the drainage hole, causing root rot or烂根 in roses.
There are many styles and materials of flower pots on the market now. How should you choose? To understand the characteristics of each pot and the correct method of selection and use, you can refer to the book "How to Grow Roses from Scratch." Here, only the use of conventional plastic pots is recommended. Outdoor cultivation suggests using second-generation Galen pots, and if it's the first-generation Galen pots, it is recommended to place a layer of ceramsite as a drainage layer at the bottom of the pot. For indoor balconies, the Qingshan pot is recommended.
Because the ventilation in indoor balconies is very poor, the Qingshan pot has more breathing holes, which helps the soil dry-wet cycle more effectively. However, using the Qingshan pot outdoors can easily lead to drought in summer.
In addition to choosing the right pot, soil mix is also very important. Many flower enthusiasts like to use fine coconut bran soil to grow roses, which I do not recommend. You can use large-particle coconut shell or well-fermented pine bark, mixed with peat soil and particle soil in a 1:1:1 ratio.
Why are potted roses easy to die?
For some common particle media, you can use perlite, which is very light and can easily float away and be washed away by water during watering. Perlite itself does not contain any nutrients and is purely a breathable matrix.
Roses require a lot of trace elements, especially potted roses. A single soil mix can easily lead to nutrient deficiencies. In addition to adding enough organic fertilizer as a base fertilizer and supplementing micro-fertilizers when mixing soil, you can also upgrade the particle matrix.
In particle soil, materials like maifanshi, akadama soil, and kazuma soil are rich in trace elements. As breathable and water-permeable particle soil, they are better than perlite when mixed with peat, pine bark, etc.
Many flower enthusiasts always end up killing their roses, and a large part of the reason is due to the poor breathability of the potting soil. For roses, which are intolerant to moisture, the dry-wet cycle of the potting soil should ideally be dry within 1-2 days in spring, at least 3-4 days in the soil should dry out, and in summer, it's best to water once a day or twice a day.
A fast dry-wet cycle does not easily cause root rot, and the rose roots can grow better. With good roots, branches naturally grow vigorously, and blooming will also increase.
If you want the potting soil to dry quickly, you need to add more particle soil when mixing. Outdoor potted roses should have at least 1/3 of the particle soil ratio, while for indoor balconies, it is recommended to increase the particle soil ratio to 2/5-1/2 because indoor ventilation is poor, and if the particle soil ratio is insufficient, the potting soil will dry very slowly.
