Cash cow maintenance guide:
Watering: drought-resistant, keep the soil slightly wet and dry, water it after drying, and keep the soil dry in winter? It should not be too wet.
2. Temperature: What is the suitable growth temperature? Between 20-32℃, it is necessary to keep warm in winter, preferably not lower than 5℃.
3. Soil: I like fertile, loose and breathable slightly acidic soil.
4. Illumination: It is more resistant to shade and strong light, and it is best to put it in a bright scattered light position.
5. Fertilization: Fertilize 2-3 times a month during the growth period, and apply potassium dihydrogen phosphate 2-3 times after the Mid-Autumn Festival. Stop applying when the temperature is lower than 15℃? Fat.
Cut the leaves of the cash cow;
The first step is to select a few healthy and complete leaves from well-growing plants.
Step 2, use clean scissors or a knife to remove the selected leaves (note that contact with the juice of the cash cow will cause skin allergies. )
In the third step, the removed leaves can be cut directly, or soaked in carbendazim for a while and cut in a soft substrate, such as river sand or coconut bricks. The cutting depth is 2 cm, which is about half the height of the blade.
Step 4, after cutting, put it in a ventilated place with scattered light, keep the soil moist without water accumulation for 8 or 12 weeks, let the substrate dry and maintain it properly. A year later, the roots of the seedlings are about 2 cm long.
Causes of yellowing of cash cow leaves;
First, improper lighting.
Insufficient light or excessive light may cause the leaves to turn yellow, so it is best to keep them in a bright and scattered position.
Second, improper watering.
Too much or too little watering may cause the leaves to turn yellow. See dry and wet, water thoroughly, don't let water accumulate at the bottom.
Third, improper fertilization.
Both fertilizer deficiency and excessive fertilization may cause leaf yellowing. If there is a shortage of fertilizer, it should be replenished in time, and the amount of fertilizer should be diluted with water.
Fourth, poor ventilation.
If the ventilation is not good, it will also cause the leaves to turn yellow. Need to increase ventilation properly.
Verb (abbreviation for verb) soil discomfort
Long-term watering with tap water will lead to soil hardening, affect the absorption of water and nutrients, and thus lead to yellowing of leaves. It is necessary to loosen the soil properly, use granular fertilizer to improve soil hardening, and it is best to replace the soil after curing for more than two years. In addition, long-term watering with tap water will also make the soil alkaline, causing the leaves to turn yellow, so ferrous sulfate is needed to adjust the soil acidity.
Reasons for the root rot of cash cow
First, the temperature is uncomfortable. Too low or too high a temperature may lead to root rot. The temperature should be kept above 5℃ and below 30℃.
Second, improper watering, too much watering can easily lead to water accumulation at the bottom, so that the root system can not breathe normally, leading to rotten roots. Need reasonable watering.
Third, improper fertilization, excessive fertilization and high fertilizer concentration will lead to rotten roots, which need to be diluted with a lot of water in time.
Fourth, poor ventilation, poor ventilation, humidity, easy to be infected with mold. If infected with Rhizopus, it will lead to rotten roots. Deal with it in time, cut off the rotten roots and disinfect them, and it is best to replace them with new ones. If the original soil is used, it needs disinfection. After treatment, put it on the pot again and put it in a cool and ventilated place for maintenance. After the plants return to normal growth, they can be maintained normally.
