Fairy ball, commonly known as grass ball, also known as longevity ball, is a perennial fleshy and pulpy herb of Fairy Family. The stem is spherical or oval with a height of 25 cm. It is green, the sphere has several longitudinal sides, and there are many needles on the sides, which are yellow-green, different in length and radial. Peanuts are spiny, silvery white or pink, long trumpet-shaped, up to 20 cm long, with scales outside the trumpet and long hair on the scales. Cactus usually bloom in the early morning or evening, lasting for several hours to a day. Many small balls are often born on the side of the sphere, which is beautiful and generous. From the appearance, cactus can be divided into velvet, wart, treasure, hair column, strong thorn, sea urchin, top flower and so on. The prickles of cactus are also long, short, thin and dense; Mao Yan has red, yellow and gold. The first planting method is: See the article "Planting Method of Cactus" on March 20th, 2008 22: 10. As long as it is properly maintained, cactus not only grows fast, but also has bright spheres and lush flowers. A warm cactus likes a high-temperature and dry environment. In winter, the indoor temperature is kept above 20℃ during the day and not lower than 10℃ at night. Too low temperature is easy to cause root rot. Second, the light cactus needs plenty of sunshine, but it can't be exposed to strong light in summer and needs proper shade. Indoor cultivation can use light to make it grow healthily. The sandy soil (or sandy loam) of potted cactus in three pots of soil requires good drainage and permeability, and contains calcareous soil. The loam, humus and coarse sand can be mixed with limestone gravel or old lime wall fragments abandoned during the demolition of old buildings, or mixed with loam, coarse sand, broken bricks, humus and old lime wall fragments. When breeding, a small amount of broken bricks should be placed at the bottom of the basin to make the drainage smooth. Fourth, it is best to plant flowerpots in early spring, and the flowerpots should not be too big, so that they can accommodate the spheres and have a slight gap. The flowerpot is too big to be absorbed after watering, and the air in the pot is blocked, which is easy to rot the roots. A few varieties with straight roots, such as bird feather jade and giant elephant ball, require deep cones. For varieties with shallow roots, such as silver hair balls and grandson balls, shallow ordinary flowerpots can be used. Five methods of changing pots When changing pots, some old roots should be cut off, dried for 4-5 days and then planted in pots. Don't plant it too deep, and the root neck of the ball should be flat with the soil surface. In order to avoid root rot, don't water the newly planted cactus, only spray it 2-3 times a day, water it a little after half a month, and then water it gradually after a month when the new roots grow. Sixth, watering Summer is the growth period of cactus, with high temperature and large water demand. Be sure to water it fully, and do it in the morning and evening when the temperature is low. It's hot at noon, so watering can easily cause the ball to burn. In the hot rainy season, water should also be properly controlled. For those cacti whose top is sunken, be careful not to water the sunken place to avoid rot, and pay more attention to watering at night. During the winter dormancy period, watering should be controlled to keep the basin soil from being excessively dry. The lower the temperature, the drier the soil in the basin should be. Adult big balls are more drought-tolerant than small seedlings. Watering in winter should be done in sunny mornings. With the increase of temperature, plants will gradually break away from dormancy, and the number and amount of watering will gradually increase. Fertilization Potted cactus can also be properly fertilized during the growing season, especially when grafting fenugreek. Apply with fully decomposed dilute liquid fertilizer once every 10- 15 days. Pay attention to fertilizer and water control after autumn, generally once a month, and stop fertilizer until early June 10. If the fertilizer is not controlled, the cactus will continue to grow, and the delicate sphere will be vulnerable to freezing injury in winter. Be careful not to touch the ball when fertilizing, and spray it with water when touching the ball. Pest control in high temperature and poor ventilation environment, pests and diseases are prone to occur. The disease can be sprayed with carbendazim or thiophanate; Spraying dimethoate can kill pests. No matter what medicine is sprayed, it should be done outdoors. I hope this helps you. . .
