Под заказ Astrophytum asterias “nudum” is a short, stubby cactus that reaches only about 21/2 inches high with a 6-inch diameter. This is a rare, hard-to-grow species not often seen in residential use. Growth Rate The needs of an Astrophytum cactus are the same as for other cacti – coarse, porous soil, and plenty of sunlight. While this cactus can be grown as a landscape garden specimen in the proper climate, it more commonly is used as a potted specimen for indoor growing or on decks and patios. Astrophytums are not vigorous plants, and they require a lot of patience to reach their full potential. Keep regularly watering and feeding them during the growing season and repot annually to give them space to develop. They need a temperate, dry winter; make sure not to overwater them, which can cause root rot. If given sufficient care, they will develop marvelous flowers once they reach maturity. Watch out for common cactus pests like aphids and scale – these can often be taken care of by a good eco-friendly pesticide, or simply wiped away with a cloth. Watering Despite their reputation as desert plants, many cacti, including the Astrophytum species, perform best if the soil gets a good drenching between periods where it dries out entirely. A potted plant should get a decent watering once a month during the growing season, but make sure the plant’s roots don’t sit in water. During the winter, watering can be less frequent. Soil Like most cacti, these species need well-drained, fairly sandy soil and will likely perish in rich soils that retain moisture. Fertilizing Fertilize during the growing season with a balanced, fertilizer, such as 20-20-20, mixed into the water. Potting and repotting Repot these cacti regularly to help them develop. Astrophytums should be repotted at the beginning of the growing season to allow them to grow into the impressive specimens for which the genus is known. Wearing sturdy gloves, lift the plant out all at once, then move to a larger pot and backfill with potting mix. Don’t overwater or overfeed newly repotted cacti, as disturbance can be hard on them. Light Give Astrophytum cacti plenty of sunlight – at least 6 hours per day if growing outdoors. As a potted indoor plant, it can do fine in a window that gets direct sunlight or intense indirect light. Temperature These cacti like warm temperatures above 70 degrees Fahrenheit all summer, then slightly cooler, more temperate winter conditions. High humidity is not advised for these plants. Propagating Astrophytum cacti propagate by seeds, which can be collected from the dried flowers. These seeds are fairly fragile: Be gentle with them before planting in a tray or pot filled with cactus potting mix. Just barely cover the seeds with potting medium. Be patient, as it can take several years for seeds to develop into flowering plants. The seeds have a fairly short shelf life and need to be planted quickly after harvesting to have a reasonable chance at rooting. Seal the tray or pot with a plastic cover to help contain moisture and heat. It can help to soak seeds before they’re planted. Once the seedlings appear, uncover the tray or pot and gradually acclimate them with increasing periods spent in direct sunlight. Within a few weeks, the seedlings can be transplanted into their permanent containers filled with cactus potting mix. |
