How to Grow Cactus (Ball Cactus) Fast? Latest Care Methods Shared

Ball cactus is the collective name for cactus family plants with a spherical shape, also known as grass ball, Changsheng wan, short-haired wan, etc. It originated in hot, dry, and rain-scarce desert regions, which shaped its traits of preferring dryness and tolerating drought. It likes to grow in well-drained sandy soil, and summer is its growing season and peak flowering season. Now let us take a look at how to grow ball cactus so it grows fast!

Growth Habits of Ball Cactus

1. Water: Ball cactus tolerates drought. It should be watered appropriately during the growing season, and kept slightly dry during the dormant period.

2. Fertilizer: Ball cactus likes fertilizer. During the growing period, apply liquid fertilizer once every 10-15 days, and stop during the dormant period.

3. Soil: Ball cactus is best grown in fertile, well-drained and airy sandy loam containing lime.

4. Temperature: Ball cactus likes warmth. Too high a temperature will force it into "dormancy". It can also tolerate low temperatures around 0°C.

5. Light: Ball cactus likes sunlight. In midsummer it should be shaded appropriately, but excessive shading will cause it not to bloom.

Propagation Methods of Ball Cactus

1. Offsets: Carry out from April to September. Cut offsets from the mother plant and let them dry for 2-3 days, or dip the cut surface in plant ash, then insert them into a pot or a tray of moist sand. Watering is not necessary; slight misting to supply water is enough. When separating offsets, do not pull them off by hand. It is best to use a small knife or scissors to cut them from the base of the offset to avoid pulling out the pith. Many offsets have already rooted on the mother plant. After cuttings are taken, keep them indoors at around 20°C for care. If placed outdoors, shade them appropriately. After 1 month, a new plant can form.

2. Grafting: Carry out during the vigorous growing period from May to July. Use grass ball, three-angled column, columnar, or vine-like cacti as rootstock. The rootstock should be thicker than the scion. First use a small knife to cut the top of the rootstock flat, then cut the lower part of the scion flat, then align the center of the offset with the central pith of the rootstock so that they press tightly together. Then use string to tie and fix it together with the pot, and place it indoors in a ventilated spot or outdoors in a shaded spot for care.

3. Sowing: Ball cactus has poor self-pollination ability and requires artificial pollination to set seed. Seeds have a lifespan of 1-2 years and need high temperatures to germinate, so sowing should be carried out in June-July. Before sowing, soak the seeds in warm water for 2-3 days. The potting soil or sand bed should mainly be loose loam. The sowing depth should be such that the seeds are no longer visible, and the distance between seeds should be kept at 2-3 cm. Supply water by the bottom-soaking method, cover with white paper or glass, let the seedlings receive sufficient light, and do not apply additional fertilizer.

Cultivation Methods for Ball Cactus

1. Soil: For potted ball cactus, you can use 3 parts leaf mold, 3 parts garden soil, and 3 parts coarse sand, plus 1 part plant ash and decomposed bone meal, mixed evenly. It is best to pot it in early spring. First place a layer of small stones about 3 cm thick at the bottom of the pot to aid drainage. The planting depth should be such that the root crown of the ball is level with the soil surface.

2. Light: Ball cactus likes a sunny environment, but exposure to strong sun will slow its growth rate. Of course, it will not be sunburned to death. If you want ball cactus to grow faster, it is best to find a cool environment for it when the sunlight is too intense.

3. Watering: The vast majority of ball cacti originate from the hot, arid desert wilderness regions of South and North America. Their root systems have strong water-absorbing ability. If watered too much, the roots will rot. Some large ball cacti will not die of dryness even if not watered for one or two years.

4. Temperature: The optimal growing temperature for ball cactus is 20-35°C. Most species like a large day-night temperature difference. Conditions of within 35°C during the day and around 15°C at night are favorable for the production and accumulation of organic matter, thereby promoting vigorous plant growth.

5. Fertilizing: Ball cactus likes fertilizer and tolerates it. Begin topdressing 1 month after repotting in spring. During the growing season, about every 20 days apply decomposed 10-fold liquid fertilizer mixed with an equal amount of 1000-fold potassium dihydrogen phosphate solution or 1000-fold “Huaduoduo” general fertilizer once. Do not fertilize in winter.

6. Repotting: When repotting ball cactus, part of the old roots should be cut off, and after drying for 4-5 days, plant it in a pot. Do not plant too deeply; it is best if the root neck of the ball is level with the soil surface. To avoid root rot, do not water newly planted ball cactus. Simply mist 2-3 times a day.

7. Pests and diseases: Ball cactus is prone to pests and diseases in high-temperature, poorly ventilated environments. For diseases, spray carbendazim or thiophanate; for pests, spray dimethoate to kill them. However, no matter which liquid medicine is sprayed, it should be done outdoors.

Four-Season Management of Ball Cactus

1. Spring: Repot ball cactus in spring when the temperature stabilizes above 10°C. After repotting and establishment, it can be placed in a spot with sufficient light for cultivation. Gradually increase the amount of watering to keep the potting soil moist. During the peak growing season, pay attention to the supply of water and fertilizer. When the temperature is relatively high in late spring, shade it from the midday sunlight.

2. Summer: In summer, ball cactus should be placed in partial shade or on a balcony with morning and evening light for cultivation. Keep the potting soil on the dry side and do not fertilize. After the temperature cools in late summer, gradually increase the water supply, and gradually move it to a place with morning and evening light for cultivation, and resume topdressing.

3. Autumn: In autumn, ball cactus should be placed in a spot with sufficient light, and the potting soil should be kept moist. As the weather gradually turns cooler, gradually reduce the amount of watering to keep the potting soil on the dry side, and stop fertilizing. When the temperature drops to around 5°C, it should be moved in time to a closed balcony or room with light to prevent cold damage.

4. Winter: Ball cactus can overwinter safely at 0°C, but the indoor temperature should be kept at around 3-5°C. In winter, it should be placed on a windowsill or balcony with sufficient light for cultivation. Pay attention to controlling water so that the potting soil is dry but not parched. The lower the temperature, the drier the potting soil should be. Do not fertilize.
