What is a good bottom fertilizer for roses?
The web tells everyone about the topic of what is a good bottom fertilizer for roses, let's continue reading!
Recently, many flower friends are eager to see others' flowers, why do others' flowers bloom while their own planted flowers don't even have a bud? Or they bloom勉强ly, and they don't look beautiful, with few and small flowers.
For potted flowers, in fact, fertilizer and water are very important. No matter what kind of potted flowers, if the management of fertilizer and water is not good, it is not very likely to grow well and bloom a lot. Fertilizer and water management not only refers to the application of water-soluble fertilizers, but more importantly, there is also base fertilizer, which is commonly referred to as bottom fertilizer. So today, let's talk about the direct relationship between bottom fertilizer and potted flowers.
As the saying goes, a plant is as good as its fertilizer, and even flowers planted in the ground need to be fertilized, let alone our potted flowers, especially roses, which require a lot of fertilizer due to their abundant blooms. To maintain sufficient fertilizer and water, bottom fertilizer is very important, and it is not easy to meet the needs of potted plants for fertilizer and water with only water-soluble fertilizers. Not only roses, but even potted hydrangeas will grow very weak without base fertilizer.
Because the effect of water-soluble fast-acting fertilizers usually lasts for 7-10 days, the effect is very quick, but the duration is short. If you cannot continue to fertilize, it is easy to cause insufficient fertilizer and water. Similarly, because the effect is very quick, if the frequency of top dressing is too high or the concentration is too high, it is also easy to cause fertilizer damage, which is not very friendly for many beginners.
However, compared to fast-acting fertilizers, some long-acting fertilizers are more friendly. They can provide nutrients for potted plants for a long time and are relatively less likely to cause fertilizer damage, making them safer.
Then, what kind of fertilizer can be used as base fertilizer?
This is a question that many新手 flower friends are very confused about. They have bought a pile of fertilizers, but they are still confused about which one to use.
Generally, fertilizers that cannot be dissolved in water can be used as base fertilizers, such as fermented solid organic fertilizers like chicken manure and sheep manure.
In addition to organic fertilizers, some chemical fertilizers can also be used as base fertilizers, such as commonly used slow-release fertilizers, controlled-release fertilizers, and some used in agriculture, such as calcium superphosphate and calcium magnesium phosphate, which can also be used as bottom fertilizers because these fertilizers cannot be dissolved in water and have a lasting effect.
Then the question arises, many flower friends are asking, I have soybean cake, can I use it as a base fertilizer for roses?
Theoretically, fermented soybean cake can be used as base fertilizer, but it is not very suitable for use as base fertilizer for potted roses because soybean cake fertilizer contains a lot of nitrogen, and roses need more nitrogen, phosphorus, and potassium elements. Too much nitrogen can easily cause the branches to grow excessively.
So, there are also explanations when choosing base fertilizers for potted plants, only the suitable one is the best. Regarding the usage of various fertilizers, there is a very detailed introduction in the book "How to Grow Roses from Scratch," and you can also refer to the previously shared articles, which also cover this topic.
How to use base fertilizer?
This is also a question that many flower friends are concerned about. Choosing the right base fertilizer is also about using the right method. Many flower friends cause fertilizer damage as soon as they use fertilizer, whether it's long-acting or fast-acting fertilizers, they are "bound to cause harm!" The root cause is still the improper use of fertilizers.
For example, when applying base fertilizer to potted plants, we usually put it at the bottom of the pot, but be careful, it's not just about piling the fertilizer at the bottom of the pot. Instead, mix the fertilizer with a small amount of potting soil and then put it at the bottom of the pot. When planting the rose seedlings, you need to cover the base fertilizer with a layer of soil and then put the rose seedlings in. It is not allowed for the fertilizer to directly touch the plant roots. This is very important.
If you are using slow-release fertilizer, it is best to put it at the bottom or on the surface. If mixed in the potting soil, it is difficult to save if fertilizer damage occurs. The reason can be found in my book "How to Grow Roses from Scratch."
Can you use fast-acting fertilizer after applying base fertilizer?
Many flower friends have asked this question before, so I'll answer it again. The relationship between base fertilizer and fast-acting fertilizer is like that between our three meals a day and snacks, so it doesn't matter. Eating too many snacks can lead to rapid weight gain, and for potted flowers, using base fertilizer plus fast-acting water-soluble fertilizer will make them grow stronger and bloom more. Of course, the concentration and frequency of using fast-acting fertilizers still need to be noticed. Finally, let's take a look at the changes in the golden celebration flower wall. We haven't seen it for two days, do you miss it a bit?
