Here is a topic related to the cultivation of roses that have already sprouted and whether they can be fertilized, with a detailed introduction below.
As the new sprouts of roses are growing rapidly these days, many friends start to worry: Oh no, I haven't fertilized yet? I haven't prepared the fish intestines yet? What should I do? Is it still okay to fertilize now?
The best time to bury fish intestines
In areas with frost, roses will shed leaves and enter dormancy in winter. This is a good time for us to apply winter fertilizer. Whether they are planted in the ground or in pots, they should be given winter fertilizer.
Roses planted in the ground
For roses planted in the ground, we usually apply raw fertilizers directly, such as chicken manure or fish intestines. However, this is generally done in the coldest month of the year when the temperature is continuously below 0 degrees, which is a better time to apply fertilizer.
Because the low temperature slows down the fermentation rate, after applying raw fertilizers, the heat generated during the fermentation process can also increase the soil temperature, which is very beneficial for protecting the rose roots. By the time the roses sprout in spring, the fertilizers are usually fully fermented and can directly provide nutrients for the growth of the roses.
Roses in pots
Can roses that have already sprouted be fertilized?
Roses in pots should also be given winter fertilizer. It is recommended not to use raw fertilizers. Instead, you can add an adequate amount of fermented organic fertilizers when repotting, which can also maintain the soil temperature and provide nutrients for the spring growth of the roses.
Brave friends can also apply raw fertilizers to potted roses, such as placing fish intestines in the potting soil. Outdoor cultivation can try a small amount, but for indoor cultivation, it is not recommended. If the soil is not covered properly and pests appear, it would be a disaster. Therefore, Green Plant Enthusiast Network suggests that you do not use fish intestines or raw fertilizers.
Why bury fish intestines?
Many friends are still confused about why fish intestines should be buried. In organic fertilizers, it can be simply understood that vegetarian fertilizers are rich in nitrogen, while non-vegetarian fertilizers are rich in phosphorus and potassium. Fish intestines belong to the non-vegetarian type, containing a large amount of phosphorus and potassium elements. After fermentation, they can be absorbed and utilized by roses, which promotes flowering. Therefore, fish intestine fertilizers can make rose flowers more abundant, larger, and more colorful.
Is it still possible to bury them now? What should be noted?
By now, we have missed the best time to bury fish intestines. Can we still make up for it?
Judging by this year's temperatures, it is still in time to bury fish intestines now. However, one thing to note is that you must keep a distance from the roots, even further!
Generally, when burying fish intestines in winter, it is necessary to keep a distance of about 20 cm from the roots. So, now it is buried, you need to keep a distance of at least 30 cm from the root system to ensure that it does not touch the roots.
What if there are no fish intestines? What can be used as a substitute?
