This will help increase soil drainage and provide good stability for the plant.
Watering Needs for Ihlenfeldtia excavata (L.Bolus) H.E.K.Hartmann
Most succulent plants store water in their leaves, making them tolerant to periods of drought. Ihlenfeldtia excavata (L.Bolus) H.E.K.Hartmann is a drought-tolerant plant, so it's best to allow the soil to dry partially before watering. Water deeply and less frequently, allowing the soil to dry out fully between waterings. The frequency of watering depends on the location, temperature, and humidity of the plant's placement.
It's essential to note that water should not be left standing around the leaves of this plant as it can cause rotting. When watering, it's best to use a watering can, watering the soil directly and avoiding the leaves. Study the plant's needs and adjust your watering schedule appropriately.
Fertilization of Ihlenfeldtia excavata (L.Bolus) H.E.K.Hartmann
Ihlenfeldtia excavata (L.Bolus) H.E.K.Hartmann does not require much fertilizer in cultivation. Feeding the plant once or twice a year with a balanced fertilizer in the growing season, preferably using a low-nitrogen and high-phosphorus fertilizer, should be adequate. It's best to follow the manufacturer's instructions for application and dosage as overfeeding can cause burning of the roots.
Pruning of Ihlenfeldtia excavata (L.Bolus) H.E.K.Hartmann
Ihlenfeldtia excavata (L.Bolus) H.E.K.Hartmann does not require frequent pruning. However, if the plant becomes leggy or overgrown, you can trim it back to its desired shape. To do this, use sterilized pruning shears, cut back to healthy leaves or parts of the stem with sharp and clean edges. Pruning will stimulate new growth and increase the plant's bushiness, giving it a better appearance.
Propagation of Ihlenfeldtia excavata
Ihlenfeldtia excavata, commonly known as the Ihlenfeldtia, is a propagation-friendly plant. It can be propagated through various methods. Here are a few techniques to propagate Ihlenfeldtia excavata:
By Seeds
Propagation of Ihlenfeldtia excavata through seeds is an easy and efficient method. You can use seeds from fresh fruits that have not yet matured or wait until the fruits dry on the plant before collecting seeds. You should avoid using seeds that are too old or damaged, as that may lead to poor germination rates.
Sow the seeds into well-drained soil in a pot or seedling tray after cleaning them with a fungicide to prevent damping-off, then moisten with water until they germinate. Cover the pot or tray with plastic wrap to retain moisture, place it under bright light, and keep it warm. The seedlings should emerge in about two weeks, at which point the plastic wrap should be removed. Keep the soil moist, and transplant the seedlings into individual pots when they are big enough to handle.
By Stem Cuttings
Ihlenfeldtia excavata can also be propagated through stem cuttings. It is advisable to take cuttings during the growing season when the plant is actively producing new shoots. Take cuttings that are about 4-6 inches long from mature, healthy plants, making sure each cutting has a few leaves. Remove the lower set of leaves from the cutting, leaving only two or three leaves on the stem.
Dip the cuttings in a rooting hormone powder to enhance root development. You can then plant the cutting in a moist potting mix, either in a pot or directly into the soil. Place the pot in a warm, bright area and keep the soil moist but not overly wet. The rooting should take place in 3-4 weeks, at which point the plant can be transferred to an individual pot.
By Division
Division is the easiest and fastest method to propagate Ihlenfeldtia excavata and works best for mature plants. This method involves separating the mature plant into multiple parts and replanting them in their original containers or in new pots. Ensure each divided part has some foliar growth, roots and a few visible rhizomes. After that, plant them in a well-drained potting mix, water thoroughly, and maintain a moist soil until new growth appears.
With the above propagation methods, propagating Ihlenfeldtia excavata will be easy and successful.
