When to Fertilize Early Spring Chinese Roses?
The editor provides an introduction to the timing of fertilizing early spring Chinese roses, and corrections are welcome if there are any mistakes!
The temperature has risen these days, and Chinese roses are about to enter a visible growth state. At this point, many rose enthusiasts start to wonder whether it's time to fertilize. However, some people say that fertilizing may cause the spring cold to occur, so what should we do?
Early Spring Fertilization Management for Chinese Roses
Whether to start top-dressing Chinese roses with water-soluble fertilizer, it is recommended to focus on these two points to make a judgment.
1. -- The Growth State of the Chinese Roses --
Whether to apply top-dressing with water-soluble fertilizer is closely related to the growth state of the Chinese roses. Since temperature changes vary by region, and different Chinese rose varieties have different cold resistance, the growth state of each pot of roses may be different.
Some roses may have very small buds, while others may have buds that are about 1 cm long, and some varieties may have already sprouted small leaves. For these last two states, we can consider applying liquid fertilizer.
When to Fertilize Early Spring Chinese Roses?
Roses with long buds about to unfold leaves, as long as the weather remains warm, unfolding leaves will only take a few days, so for this state of roses, we can consider applying water-soluble fertilizer, which will promote the quick unfolding of the buds. Of course, if we have already fertilized in winter, it's also fine not to apply water-soluble fertilizer at this stage.
Roses that have recently unfolded leaves indicate that they have started growing. If the temperature remains warm, they will enter rapid growth, and at this time, they require more fertilizer and water, so top-dressing with water-soluble fertilizer is necessary.
Generally, when Chinese roses have grown 3-5 small leaves, it is necessary to apply water-soluble fertilizer promptly, because the growth rate is very fast, and timely use of water-soluble fertilizer can avoid the deficiency caused by the slow release of long-acting fertilizer, reducing the occurrence of blind buds.
2. -- Recent Weather Changes --
But many rose enthusiasts worry that after applying liquid fertilizer, the new branches will grow quickly, and if they encounter a cold snap, the new buds will be frozen.
In fact, personally, I think this worry is unnecessary because the growth rate of Chinese roses in spring is not greatly affected by whether we apply water-soluble fertilizer. Even if we do not apply water-soluble fertilizer, as long as the weather is warm, Chinese roses will grow rapidly with the nutrient accumulation from winter and the release of nutrients from long-acting fertilizers.
The difference in the growth of Chinese roses with or without the application of water-soluble fertilizer is more reflected in the robustness of the branches, not the growth speed.
If you are worried, you can avoid applying water-soluble fertilizer in the early stage of rose sprouting. If you want the new branches of Chinese roses to grow stronger, you can first check the weather forecast for the next 40 days, although it's not very accurate, it can still give you a direction on whether there will be a significant drop in temperature.
If you really encounter a cold snap, and the new buds of the potted Chinese roses are already quite high, you should move them indoors temporarily to avoid the cold. For ground-planted roses, you can simply cover them at night for protection.
These days are relatively warm, and Chinese roses have明显 started to sprout. If no fertilizer was applied in winter, you should quickly apply long-acting fertilizer, and after the leaves unfold, you can apply a thin solution of fast-acting liquid fertilizer.
The above is the detailed introduction to the early spring fertilization management of Chinese roses and when to fertilize early spring Chinese roses. Have you understood it?
