How to plant and revitalize the catalpa tree stump
Today, the editor will elaborate on how to plant and revitalize the catalpa tree stump and introduce some tips for growing green plants and flowers. Let's proceed with the introduction.
Every spring, many friends dig up stumps from the mountains, using various substrates and methods to cultivate them. Generally speaking, the survival rate of freshly dug stumps is higher due to low temperatures before germination.
However, after some stumps survive, due to factors such as the habits of tree species,移植 from south to north, and root pruning, they may experience reverse germination in summer. For example, ligustrum, campsis, and golden berry stumps may wither and curl in the spring.
When maintaining mountain stumps in summer, understanding the root of the care measures is the most important thing. Let's look at the common mistakes in summer maintenance of mountain stumps, which are closely related to daily care.

1. Watering mountain stumps
People who often grow flowers always talk about the watering methods of flowering苗木, and there are many true insights. These watering practices may seem ordinary, but they have scientific principles.
Friends who maintain mountain stumps worry most about insufficient water and roots that do not grow due to water deficiency. In fact, these concerns are unnecessary.
Because watering the mountain stumps planted in the same year, after they survive, it is best to keep the potting soil slightly dry. The soil slightly moist but a bit dry is more conducive to root growth.
This type of soil (river sand) has high permeability, accelerates microcirculation, and does not accumulate alcohol, nitrogen, or carbon dioxide, which is the most favorable growth condition for roots.
Even if the leaves wilt for a day occasionally, it is fine; they won't die from drought for a day or two. If watered too frequently, the new roots will rot, and after the stump roots rot, they cannot absorb water. The leaves will consume the water in the trunk, and without water, the new shoots will droop and the leaves will fall, which is what we commonly call "drying the living stump by overwatering."
So when maintaining living stumps in summer, remember to water in the morning, not at night or at noon; use rainwater or river water, not tap water.
Water the appropriate potting soil temperature, not the high-temperature water exposed to the sun or low-temperature well water; do not water uncomposted waste water such as vinegar, beer, vegetable leaves, soybean water, or waste oil; the most important thing is to water lazily and keep the potting soil slightly dry.

2. Creating a cool and ventilated growing environment
During the dog days of summer, when the temperature is high, and the mountain stumps that have survived for a few months have sprouted leaves, the stronger the light, the greater the transpiration pull, and the more water evaporates.
And the stumps have few roots, absorbing less water than the evaporation amount. This is a common situation, which manifests as wilted leaves. If the maintenance measures are not changed in time, it may lead to a dried stump.
At the end of the day, it's about the mismatch between the amount of roots and leaves. Some friends' solution is to water more. In fact, even if you soak it in water, it's useless because it has so few roots and can't absorb the water. It's like someone with a poor appetite; no matter how delicious the food is, they can't eat it.

There are 3 solutions: one is to use shade netting to reduce temperature. Cover with shade netting to reduce the duration of midday sunlight, which can reduce strong sunlight on leaves and lower the temperature of the potting soil.
Because the suitable temperature for root growth is 22-30 degrees, above 35 degrees, growth stops, and it cannot absorb water, which can improve the survival rate of living stumps.
The second is to reduce temperature through ventilation. The third is to bury the pot to reduce temperature. If conditions allow, dig a slightly larger hole than the flower pot, fill it back with soil, place the pot with the stump directly in the refilled soil, and cover the surrounding area with sandy soil. The pot surface should also be covered with sandy soil, as long as it is higher than the surrounding ground and has good drainage.
The above three methods are actually changing a lifestyle of low income and high expenses to one of low income and reduced expenses.
The three methods can be used together or separately, depending on reducing root temperature, reducing strong sunlight, and increasing ventilation and aeration.

3. Cooling measures for maintaining stumps on the balcony
Make a sandbox and place the tree stump bonsai on it, cover it with shade netting, and use wood chips, river sand, or moss around the pot, but not on the pot surface.
Usually spray the covering material, and the evaporation of water can lower the temperature around the pot and increase the humidity of the air. As long as the temperature is lowered and the humidity is high, it can reduce the evaporation of leaves.

Conclusion: Generally speaking, the reverse germination of living stumps in summer is not related to the potting soil material but rather to these four points: watering, temperature, sunlight, and ventilation.
As long as the potting soil is slightly dry, the temperature is low, there is less strong sunlight, and the ventilation is good, by the time Mid-Autumn Festival arrives with cool weather, there is no longer any danger of reverse germination, and everything will be fine.
