What should I do if the buds of my 'Duoduo' roses turn yellow and fall off every week?
Article Guide: Learn about the knowledge of green plants and flowers on how to deal with the yellowing and falling off of 'Duoduo' rose buds that are not opening, read on!
Lately, many friends have asked why their rose buds won't open and the small buds have fallen off. Looking at these withered buds in the picture, it's really heartbreaking.
The most common reason for rose buds not opening and turning yellow and withering is a lack of fertilizer. You might be as puzzled as this flower enthusiast, wondering how there can be a lack of fertilizer when you have been applying 'Duoduo' fertilizer every week.
Next, let's get to the point: the correct usage of 'Duoduo'. If your method is incorrect, you might encounter the same problem as the flower enthusiast above. Moreover, there is a high risk of fertilizer damage.
Correct usage of 'Duoduo' fertilizer
How should 'Duoduo' be used? Dilute it 1000 times with water, pour it into the potting soil, or spray it on the leaves. It's that simple! Yes, that's right, it is that simple, but simplicity should not overlook details.
Flower enthusiasts usually buy 'Duoduo' fertilizer in pre-packaged form, and the seller often provides a small 1G spoon. Yes, that's right, a 1g spoon. However, the problem often lies with this spoon.
If one spoon is 1g, then one spoon diluted in 1L of water is 1000 times. As mentioned above, this flower enthusiast has been using 'Duoduo' every week, but the roses are severely lacking in fertilizer. The root cause is the lack of sufficient long-acting organic fertilizer, and there has also been a miscalculation in the dilution ratio of 'Duoduo'. Adding 1g of fertilizer to 10L of water results in a dilution ratio of 10,000, which is far from enough for roses, which are known as 'fertilizer baskets'.
Many flower enthusiasts have this thought, "I'm afraid of fertilizer damage. Every time I fertilize, the leaves turn yellow, and I don't know how much to put. I dare not use fast-acting fertilizer anymore."
If you are afraid to use fast-acting fertilizer, then I suggest you read the following content carefully and then start using fast-acting fertilizer again.
Why does 'Duoduo' cause fertilizer damage as soon as it's used?
The main problem with 'Duoduo' causing fertilizer damage is still in the concentration of the dilution.
Previously mentioned, we usually choose to use a 1g spoon to measure the amount of 'Duoduo'. The root cause of immediate fertilizer damage upon application lies in this detail.
A 1g spoon, when measuring water, weighs 1g and has a volume of 1ml. However, when measuring 'Duoduo', one level spoon is actually 2g of 'Duoduo'. Therefore, if you mix one spoon of 'Duoduo' with 1L of water, the actual concentration of the fertilizer solution is 500 times.
The normal concentration for using 'Duoduo' is 500-1000 times. This concentration does not cause fertilizer damage when used on crops and robust potted plants. However, pay attention, because here's another 'but': many of our flower enthusiasts' potted plants are not very robust!
The robustness of the seedlings and their tolerance to fertilizer are directly related. Weak seedlings have poor fertilizer tolerance, while robust seedlings have good fertilizer tolerance. So, using the same 1g spoon and adding 1L of water, some flower enthusiasts' seedlings grow well, while others suffer fertilizer damage upon fertilization. The problem lies here. You think you're mixing a 1000 times concentration, but in reality, it's a 500 times concentration.
Look, a seemingly simple fertilizer solution preparation can cause irreversible damage to the seedlings due to a small neglect of detail. Paying attention to details is very important.
Also, to make the seedlings grow strong, relying solely on water-soluble fertilizer is not enough. The effect of water-soluble fertilizer is short-lived, and if we forget to apply fertilizer once, the potted plants will starve. Therefore, using long-acting organic fertilizer in combination is a very practical method to maintain vigorous growth of potted plants.
The above is the experience and knowledge on what to do if 'Duoduo' rose buds still turn yellow and fall off every week. I hope this article can be of some help to you!
