How to grow rat tail cactus well? A full breakdown of the latest tips

The rat tail cactus is one of the earliest cactus species used for ornamental cultivation. Also known as medicinal sage, salvia, and so on, it is a succulent plant of the genus Aporocactus in the cactus family, native to the high-altitude desert regions of Mexico. Its long modified stems closely resemble a rat's tail and are very unusual. Now let's take a look at how to grow rat tail cactus well!

Growth habits of the rat tail cactus

The rat tail cactus prefers a warm, humid environment with plenty of sunlight. It is not cold-tolerant, and is relatively tolerant of shade and drought. The soil should be fertile, airy, and well-draining. In winter, the temperature should not fall below 10°C. During the summer growing season, it needs plenty of water, and should be misted frequently to maintain high air humidity. Fertilize once a month. It prefers well-draining, airy, fertile soil, which can be made by mixing leaf mold, sand, and loam in equal parts.

Propagation methods for the rat tail cactus

1. Cuttings: During the growing season, cut plump modified stems from the rat tail cactus as cuttings, cutting them into 8-10 cm segments; they should not be too short, as short ones do not root easily. After drying in the air for 1-2 days, insert them into a sand bed or peat soil, not too deep. The cutting medium should not be too wet; a water-holding capacity of 60-70% is suitable. They will root in about one month after insertion, and can then be potted up. This method propagates quickly and is commonly used in production.

2. Grafting: Through grafting, the rat tail cactus can grow into an attractive hanging plant form. Flat grafting and slant grafting can be used, with May to September being the most suitable time for grafting. Choose a branch of Pereskia that has not fully lignified, cut it off 2-3 cm from the branch, and whittle it into a cone about 1 cm long. Insert the base of a young, green rat tail cactus stem into the pointed cut of the rootstock; no tying is needed. After grafting, take care to shade it and control watering; humidity should not be too high, otherwise the graft will fail. If the scion remains fresh and green after more than ten days, it has taken successfully.

1. Potting soil: For the rat tail cactus, prepare the potting soil with equal parts leaf mold, sandy soil, and loam, and mix in a small amount of sesame paste residue and bone meal as a base fertilizer.

2. Humidity: When grown outdoors, the rat tail cactus should be placed in a spot with ample light and shelter from rain. When grown indoors, maintain a certain level of humidity in summer, and avoid prolonged dryness, which can cause the modified stems to turn yellow and wither.

3. Light: When the rat tail cactus is grown outdoors in midsummer, it needs appropriate shading. When moved indoors in winter, it needs plenty of sunlight and reduced watering.

4. Watering: When watering the rat tail cactus, be sure to water thoroughly only after the soil has dried out. Do not let the soil become too wet, to avoid root rot. Especially after flower buds appear, water even more sparingly to avoid bud and flower drop. In winter, the soil should be relatively dry, and watering should be controlled.

5. Fertilizing: Fertilize the rat tail cactus once a month, and apply liquid fertilizer once every 10-15 days during the growing period to promote lush growth and large, brightly colored flowers.

6. Temperature: Potted rat tail cactus is generally moved indoors before Frost's Descent, and the room temperature should not be lower than 10°C. The best time to move it outdoors is after Qingming.

7. Pruning: The rat tail cactus has slender stems that sprawl and branch heavily. When potted, it needs a support frame or a hanging basket. The whole plant should be pruned to maintain a graceful shape.

8. Pests and diseases: Spot disease sometimes occurs on the stems of the rat tail cactus. It can be sprayed with a 600-fold dilution of 65% zineb wettable powder. For red spider mites, spray dimethoate regularly as a preventive measure.
