How to Grow Haworthia fasciata: Care Methods, Precautions, Rooting, and Dealing with Blackened Leaves
The appearance of Haworthia fasciata is similar to that of aloe, but the thick, fleshy leaves of Haworthia fasciata are studded with banded white star-like dots, making it look fresh and elegant. Grown in a pot, it will be a bright embellishment in the home. So what are the care methods and precautions for Haworthia fasciata? How do you get it to root? What should you do if the leaves turn black?
1. What are the care methods and precautions for Haworthia fasciata?
[Care Methods]
1. Soil: Haworthia fasciata is not demanding about soil, and a fertile, loose sandy loam is suitable. When potting, because the root system is shallow, it is best to plant it shallowly, using fertile, well-drained leaf mold mixed with coarse sand.
2. Watering: During the growing period, Haworthia fasciata only needs the potting soil kept moist. During the semi-dormant periods in winter and midsummer, it should be kept dry, with watering strictly controlled. If the potting soil is too wet in winter, it easily causes root rot and leaf shrinkage.
3. Sunlight: In summer, place Haworthia fasciata in a semi-shaded spot for care, or give it 50% shade, and the leaf color will become even more beautiful. In spring and autumn, since the temperature is not very high, give it direct sunlight to help it carry out photosynthesis and accumulate nutrients. In winter, keep it indoors in a place with bright light.
4. Temperature: The optimum growing temperature for Haworthia fasciata is 15°C to 32°C. It fears high temperatures and stuffiness, and enters dormancy when the summer heat exceeds 33°C. It also fears cold and frost, and the overwintering temperature needs to be kept above 10°C. It also enters dormancy when the winter temperature drops below 7°C. If the ambient temperature approaches 4°C, it will die from frost damage.
5. Fertilizing: Haworthia fasciata does not much like fertilizer. Applying 1-2 light feedings each spring is enough to meet its needs.
6. Pests and diseases: Haworthia fasciata is sometimes harmed by root rot and brown spot disease, which can be sprayed with a 1500x dilution of 65% zineb wettable powder. Pests include whiteflies and scale insects, which can be killed by spraying with a 1000x dilution of 40% omethoate emulsifiable concentrate.
[Precautions]
1. If Haworthia fasciata is grown indoors, place it near southeast-facing doors and windows so it can receive light, and every one or one and a half months, move it outdoors for two months. Otherwise its leaves will grow thin and yellow, and new branches or leaf stalks will be slender with elongated internodes, in a state of leggy growth.
2. The root system of Haworthia fasciata fears waterlogging. If water accumulates in the pot, or if it is watered and fertilized too frequently, it easily causes root rot. Therefore, watering and fertilizing must be well controlled.
3. When Haworthia fasciata enters its dormant period, do a good job of controlling fertilizer and water. When watering it, do so at noon on a sunny day when the temperature is relatively high.
2. How do you get Haworthia fasciata to root?
1. Division: Large plants often produce small offsets beside them. In April to May, when repotting, cut the small offsets away from the mother plant, let the wounds dry, and then plant them separately.
2. Cuttings: Carry out in May to June. Cut a fleshy leaf from the base, insert it into the growing medium, and it can root 20-25 days after insertion.
3. How do you behead Haworthia fasciata?
First, do the preparation work before beheading, which is preparing the beheading tools. Buy fishing line at a fishing supplies store; black fishing line, size 1.2 is quite suitable. Buy a better quality one. Choosing black line lets you see it more clearly, and the line does not need to be too thin. Also prepare the common tools for trimming flowers.
Then you can "behead" it. First cut a suitable length of fishing line, find the best point for wrapping the line around, use pointed tweezers to clamp the line and slowly place it at the very bottom of the plant, as close to the lowest end as possible to prevent cutting the leaves badly, then gently pull, and the beheading is successful.
4. How do you grow Haworthia fasciata so it blooms?
It will bloom in spring and autumn. The potting soil should be mainly granular soil, with a small amount of peat soil added, and slow-release fertilizer placed in it. It is not cold-tolerant and also fears high temperatures. Avoid exposure to strong sun, and by all means avoid the potting soil being wet for long periods. As for watering, water when dry, and water thoroughly when you do. Below 10 degrees it will go dormant, and it must not go below 5 degrees.
5. What should you do if Haworthia fasciata leaves turn black?
Blackened leaves of Haworthia fasciata may be caused by direct exposure to strong sunlight. If this happens, move the plant to a bright indoor place or a shady outdoor environment, and after a period of time it will return to green.
In spring, summer, and autumn, succulents should not be placed in direct sunlight; in winter, they can be placed indoors in a spot with ample light to receive sunlight.
When growing Haworthia fasciata, you must also pay attention to watering. Water only after it dries out, and especially prevent the potting soil from being too wet, which easily causes root rot.
If the leaf tips of Haworthia fasciata wither, you can spray water on the plant when the air is dry. You can cut an empty mineral water bottle in half, poke a few holes in it, spray a little water inside the bottle wall, and cover the Haworthia fasciata inside; or place the flowerpot in a sealed glass fish tank for care, which also works very well.
