A Brief Discussion on the Watering of Echeveria
If you want to learn about the introduction of Echeveria, a type of succulent plant, this brief discussion on watering Echeveria will surely be helpful to you. Let's get to know it together!
I mainly take care of Echeveria, so I use the first person perspective for Echeveria. The entire article discusses the watering of Echeveria, writing whatever comes to mind, which can be a bit disorganized. The care theory for Sedum is far behind that of Aizoaceae, globes, and Haworthia. I would rather see the following text act as a catalyst for triggering thoughts among plant enthusiasts about the care of Echeveria, rather than debating whether my views are right or wrong.
A short, compact, and full rosette is an essential physical feature of an excellent Echeveria, and controlling water levels undoubtedly has a profound impact on the quality of the rosette. The direct target of water is the root system, and the long-term effect of water on plants is determined by the crown size and distribution area of the root system. Plants will gradually adjust their physiological functions to adapt to the external watering environment. A consistently moist soil environment is not good news for Echeveria, as abundant water will limit the growth of Echeveria roots.
With sufficient soil moisture, a part of the root system can maintain the normal water needs of Echeveria, which is not beneficial for the development of the root crown and the deepening of the roots. A strong root foundation can enhance the plant's resistance to adversity, the most direct manifestation being resistance to short-term flooding and drought. A large number of deep roots can not only absorb more water from the soil during drought but also absorb more oxygen during flooding, preventing rapid suffocation and root rot.
In a slightly moist soil environment, the roots, stems, and leaf tissues of Echeveria can grow faster. In a greenhouse with well-controlled temperature and humidity, Echeveria can grow more rapidly than in an open environment. This is because the microenvironment of the soil in the greenhouse with good temperature and humidity is suitable for the roots to absorb water and nutrients, and the high humidity and gentle environment of the greenhouse make the plant itself full, but the proportion of dry matter is relatively low. I personally believe that sufficient water allows the cell's vacuoles not to need to absorb water at a higher osmotic pressure, as a lower concentration of osmotic pressure can meet the cell's water needs in a long-term high humidity environment.
The plant itself will always adjust to adapt to the external environment, and my philosophy is to enhance the plant's resistance to adversity by relying on its adaptive characteristics. Starting from the watering process, I intermittently let Echeveria be in a semi-dry state, allowing the roots to develop both horizontally and vertically, while also increasing the dry matter content in the leaves and enhancing resistance to diseases, pests, and high temperatures and strong light.
By controlling water levels, we can assist in controlling the growth rate of Echeveria and help it shape a high-quality rosette. Echeveria leaves grow upwards in a spiral pattern. In a semi-dry state, the bottom old leaves of Echeveria first wilt, followed by the upper young leaves of the rosette. The free water content in the stems and leaves of Echeveria decreases, and the overall metabolic rate of the plant slows down. When external water is supplemented appropriately, the roots immediately absorb water, and the upper young leaves of the rosette first absorb water, followed by the lower old leaves. The entire water supplementation process is relatively fast, with the leaves of the rosette regaining fullness in half a day to a few days.
When Echeveria is in a semi-dry state for a long time, it will transition to a dormant physiological state, where the leaves lose water severely and become as thin as paper, and some roots dry out. At this point, after watering, Echeveria will not recover to a full state in the short term, only when the roots grow new root hairs can the leaves slowly regain fullness. Based on the above characteristics of Echeveria, I believe that intermittent semi-dry methods can control the growth rate of Echeveria and ultimately result in a short, compact, and full rosette.
