Many plant lovers run into all sorts of problems when growing plants like pothos or money tree. Don't be fooled - pothos and money tree may be easy to grow, but growing them well is not so simple.
Through long-term observation, here is a summary of the problems that arise when growing foliage plants like pothos and money tree.
Ambient temperature
Everyone knows pothos is easy to grow - just put it in water and it survives. But after a while, problems like yellow leaves appear. This happens most often in early spring and other times when the temperature difference is large. So you need to know that although pothos is easy to keep alive, if you don't put it in a relatively constant-temperature environment, it is still quite prone to various problems.
Comparisons have been made: for example, placing it in the living room, bedroom or other places where the temperature changes little. Pothos always grows better than pothos left out on the balcony all the time. So when caring for pothos and money tree, the first priority is to control the surrounding ambient temperature. But it needs ventilation.
Sometimes, in pursuit of a certain effect, people like to grow many plants together, making it very dense. Although it looks like a mass of green, very beautiful and pleasing to the eye, after a while, if you are rather lazy, problems will still appear. Because those who like growing pothos and the like can be said to be rather lazy people.
The reason is actually very simple: people like to huddle together for warmth. Being together for a long time accumulates heat, and this easily leads to problems.
We all know that with money tree, the most important thing when caring for it is protecting its roots. If the roots are damaged, it gets very troublesome. First you need to know that watering too much causes the roots to rot. If the location is bad, put it in a ventilated place. This way there generally won't be too many problems. If disease appears, you can use carbendazim to disinfect it. If the roots are damaged, you can cut off the rotten part, then rub the new wound with garlic, which can also serve to disinfect it.
