How to care for potted roses that have not been repotted for many years?
Today's introduction is about how to care for potted roses that have not been repotted for many years in terms of green plant flowers. Next, the editor of this site will introduce to everyone.
It's time to repot and fertilize the roses again. Some rose enthusiasts ask: "The potted roses no longer have a larger pot to change, what should I do? Can I not repot them?" If you also have such a problem, today's article will definitely enlighten you.
What should I do if there is no larger pot available for my potted roses in winter?
Rose enthusiasts usually encounter the situation where there is no pot to change, possibly due to limited space for a larger pot, or because the original pot is already large enough with no larger pots available. In such cases, we can either change the soil without changing the pot or add fertilizer without changing the pot. The specific operations can be divided into the following three situations.
1. Change only the soil, not the pot
If our potted roses have not been repotted for one or two years and there is no larger pot available, at this time, we can only change the soil without changing the pot. Remove half or 2/3 of the old soil, retain some protective heart soil, then prune the roots, cut off the withered roots, shorten the overgrown roots, add a sufficient amount of fermented organic fertilizer to the bottom of the pot as a base fertilizer, and then repot with fertile new soil in the original pot. This is a relatively conventional operation method.
2. Add fertilizer to the bottom of the pot without changing the soil
If our potted roses have not been repotted for a short time since the last soil change, and we do not want to change the soil, we can directly add a sufficient amount of long-acting fertilizer to the bottom of the pot to replenish the soil fertility.
Specific steps:
If the potting soil of the potted roses has seriously eroded and is now half full, we can directly remove the roses from the pot, then mix one part rose nutrient soil with two parts fermented organic fertilizer, add it to the bottom of the pot, and the total amount added should make the pot 8-9 parts full when the roses are put back.
If the roots of the roses do not show obvious winding, the roses can be placed back into the pot with the intact original soil ball. If the roots show obvious winding, a part of the bottom winding roots can be cut off and then placed back in the pot. Finally, fill the gaps around the pot with new soil.
After planting, you can water thoroughly once or follow the usual watering frequency. Anyway, during the winter dormancy period, the demand for water is very low, so there is no need to water deliberately if the original soil is not dry.
3. Remove some topsoil and add fertilizer
Many rose enthusiasts use large belly陶pots or planting boxes, especially for large climbing roses. In such cases, it is not practical to add fertilizer to the bottom. It is difficult to repot a large belly pot, either by digging out the soil bit by bit or breaking the pot. If you don't want to dig it out or break the pot, you can only add fertilizer to the topsoil.

Specific steps:
For large belly pots with full soil, you need to dig out some of the surface soil, remove 8-10 cm of the original soil, mix a small amount of original or new soil with twice the amount of fermented organic fertilizer and an appropriate amount of slow-release fertilizer, mix well, and then fill it back into the pot, making it 8-9 parts full.
If it's a planting box with full soil, some of it also needs to be dug out. If the soil has eroded a lot and is not full, it is recommended to loosen the topsoil first, then add the mixed new soil with fermented organic fertilizer to the surface.
So, what is the difference between adding fertilizer to the bottom and adding it to the surface? Isn't it more convenient to add it directly to the surface?
If you often add organic fertilizer to the surface, you can dig into the surface soil and see that it is easy to expose the roots.
Originally, the roots of the roses grow downward and have a tendency to seek fertilizer. Adding fertilizer to the bottom of the pot is more in line with the growth habits of rose roots. If we add fertilizer to the surface of the pot soil for a long time, the surface soil will have sufficient fertilizer and water, while the soil at the bottom of the pot will lack nutrients. In this case, the tendency of rose roots to seek fertilizer will be very obvious, so the roots will all grow on top. The roots at the bottom will also gradually lose their activity due to the lack of sufficient fertilizer and water for a long time.
But for roses, having something to eat is better than starving, so if you can't add fertilizer to the bottom of the pot, adding it to the surface of the pot is also good.
