How to prevent roses from dying after repotting
Recently, a friend called me to complain about this, saying it happened in spring. He mentioned that he had been growing a rose for three or four years, noticed its poor growth, so he changed the potting soil. After shaking off the soil from the roots, he busied himself with pruning the roots and branches. After transplanting it into new potting soil, he watered it thoroughly and placed it in a shaded and well-ventilated area to recover. He took great care of it during this period, but after half a month, the rose did not take root and survive after repotting. The branches and leaves withered and died, which made him very sad. He said he wished he hadn't repotted it. I don't know if other flower enthusiasts have encountered this, but I have experienced it twice when repotting roses, and it only survived the third time. I'm really ashamed!
Generally, after growing roses in a pot for about 2 to 3 years, it is indeed time to change the potting soil. After all, the soil is limited by the space of the pot, and there's only a little soil. Over time, it becomes compacted and nutrient-poor due to being flushed by water and absorbed by the plant. If it's not changed, it will also affect the growth of the plant. So, how can we prevent roses from dying after repotting? Read on:
① Repot roses with root soil
Usually when repotting roses, if the plant is about a year old or does not have rotting roots, do not remove the root soil during repotting. Repotting with root soil increases the survival rate of roses. For beginners, when they shake off the root soil, they may accidentally injure the rose roots. If the injured roots are not thoroughly disinfected after transplanting, the moist soil may cause bacterial growth, leading to the difficulty of surviving for roses with damaged roots.
Suggestion: When the potting soil is not too dry or too wet, first cut off excess branches and leaves to avoid nutrient consumption. Then, turn the pot upside down, hold the rose with one hand, and it can be easily removed from the pot. Use a knife to cut off the outer circle of the root soil, including the bottom soil, with a thickness of 2 to 3 centimeters. Then place it in a new pot, fill the sides with humus soil, water thoroughly, and place it in a scattered light and well-ventilated environment. During this period, you can spray water on the pot to increase humidity. This method of repotting only takes about a week for the rose to adapt and grow in the pot, gradually increasing sunlight for normal cultivation.
② Trim roots and soak in root-promoting powder to encourage root growth
If the rose has been grown for about 3 years, it's inevitable to have old, withered, and rotting roots. Once the rose is out of the pot and the roots are pruned, the most crucial step comes. If the roots are not disinfected before transplanting, the wound will be exposed to water and bacteria will multiply, causing black rot. Moreover, not only should we disinfect the rose roots, but also the new potting soil to avoid bacterial and pest contamination, which can cause root rot and make it difficult to take root.
Suggestion: First, cut off unnecessary branches and leaves to reduce water evaporation. When the potting soil is slightly dry, remove the pot, shake off the root soil, cut off withered and rotting roots, then soak the rose roots in a solution of root-promoting powder. The root-promoting powder can kill bacteria and promote the growth of new roots in roses. Soak for 5 to 10 minutes, then plant it in new soil after slightly drying.
When planting bare-root roses, place broken tiles at the bottom of the pot, then add soil, place the rose in the center, spread the roots, continue to fill the soil, gently lift the roots to make sure the soil and roots are in full contact, press the soil lightly with your hands (do not press hard), water thoroughly, and place it in a shaded and well-ventilated area to recover. Avoid direct sunlight. Keep the potting soil moist, spray water on the branches and leaves to increase humidity and prevent dry leaves, which is also beneficial for root growth. It takes about a month for the rose to adapt to the environment and take root after bare-root pruning and repotting.
Remember, do not apply fertilizer to the bare-rooted potting soil, as overly fertile soil can cause root burn. Moreover, roses prefer acidic soil, so the soil mixture should be a combination of humus soil, garden soil, and coal cinders.
Note: After repotting roses, the plant needs to adapt to the new environment, especially for those with pruned roots. Since the roots cannot absorb nutrients from the soil in time, they cannot provide nutrients to the branches and leaves. In this case, do not water excessively or not at all. Excessive or insufficient watering will affect root growth. Keep the environment well-ventilated and water when the surface of the potting soil is dry. Most importantly, it is best to repot roses in early spring when they start to sprout or in winter.
