How to Revive a Rose Bush with Only Stalks Left
The editor provides you with small green plant maintenance tips on how to restore a rose bush with only stalks left and detailed techniques for rose plant care. Next, the editor will introduce some information to everyone.
When growing roses, people often encounter various leaf-dropping situations. The main component of roses is leaves, which also play a crucial role in photosynthesis. Once the leaves start to fall, the roots will shrink accordingly. Moreover, after the roots shrink, it will affect the absorption of nutrients and water, further impacting the growth of the plant.
Therefore, the health of a rose bush is not determined by how many flowers it blooms but by whether it has lush branches and leaves. There are many reasons for leaf drop, and I have previously discussed various factors leading to leaf drop. Today, I will focus on the reasons for the massive leaf drop in summer roses and also review some knowledge I have shared before.
One: High Temperature and Dehydration Lead to Leaf Drop
Now we are in the high-temperature season, and rose plants require a lot of water. Normally, potted roses need to be watered almost every day, and lack of water is one of the main reasons for yellow leaves and leaf drop during this season.
In summer, the damage caused by water deficiency in roses is twofold.
1: Root Shrinkage
The roots will shrink due to lack of water. At this point, the plant will reduce some leaves to protect the roots, using the remaining water to survive. Once water is replenished, the plant will regrow, but the lost leaves cannot be retrieved.
2: Sun Scorch
When the plant lacks water, the roots cannot absorb water, and the leaves will not receive water replenishment. The leaves will continue to perform photosynthesis and will also lose water due to strong sunlight. Consequently, the leaves will gradually wilt until they wither.
If we replenish water promptly after the leaves show signs of dehydration and wilting, some of these wilted leaves may recover, while the others will turn yellow, wither, and eventually fall off. If the sunlight is strong and the temperature is too high, the plant may skip the wilting stage and wither directly, becoming crumbly when touched.

3: Light Watering and Gradual Application
Seeing this subtitle, are you guys stunned? Because when it comes to fertilizing, we advocate light fertilization and gradual application to avoid over-fertilization and excessive fertilizing frequency, which can cause fertilizer damage.
But when watering, many gardening enthusiasts also like to do this. When they see the roses are short of water, they add a little. Sometimes, they are afraid of root waterlogging if they water too much, so they water a little, thinking that this can prevent the roots from being soaked and reduce the chance of root rot.
However, this can lead to some leaves turning yellow and eventually falling off. This is because every inch of leaf corresponds to an inch of roots, and rose roots are spread throughout the soil. If we don't water thoroughly each time and only add a little, it will result in uneven moisture distribution in the soil, causing the roots in the dry soil to shrink and the leaves to turn yellow and fall off.
PS: The Editor's Advice
Watering seems like a simple task that cannot be simpler, but many新手 gardeners struggle to master the knack, leading to the majority of新手 roses dying from overwatering. Below, I will discuss the method for watering roses.
1: Do Not Water Until Dry - Rose watering should not be based on the number of days or the dryness of the surface soil. Before watering, you must stick your finger or a chopstick along the edge of the pot, and only water when the middle layer of soil is moist but no water can be squeezed out. Since the weather and temperature are changeable, and each seedling's condition is different, it is not appropriate to measure based on a standard of watering every certain number of days.
