| Life form | Grassy onion |
| Family | Amarillidaceae |
| Origin | South Africa |
| Ease of cultivation | Easy with little difficulty. |
| The size | It reaches 30-40 cm in height. |
| Growth rate | The average bulb increases every year and can reach 7-8 cm. As the growth grows, children bulbs. |
| Lifespan | A perennial fairly stable plant |
| Temperature | For Haemanthus Catarina, optimum temperature in summer: up to 68-73,4 ° F in winter, is not lower than 64,4 ° F. Haemanthus belotsvetkovy less thermophilic, can withstand temperatures to 50 ° F. |
| Humidity | Requires medium humidity. In the flowering period it is desirable to spray with soft water. |
| Lighting | Lit place, a bright light, but in the summer requires a small shade. |
| The soil | Fertile, loose soil is suitable. You can take 1 part garden soil (earth greenhouse can use, peat moss), 1 part humus (leaf earth), 1 part of coarse sand or perlita. Need good drainage. Always use a pot with a hole. |
| Watering | During flowering and growth, the soil should be moderately moist, but do not dry out, water every 3-6 days. By the autumn watering cut. In the winter, watering is limited. |
| Fertilizer | Feed the diluted liquid fertilizer once a month during the growing season. The plant can not be overfed, so that it does not stop blooming. |
| Reproduction | Branch of bulb-children, which are planted in small pots at the same depth on which grew an adult plant. The size of the pot is increased as the bulb grows. Plants bloom for 3-4 years. Can be propagated by seeds (for example, after artificial pollination). Seeds are planted in a mixture of peat and sand. Seedlings appear after 2-3 weeks. Seeds should be fresh, because they very quickly lose their germination. |

| Transfer | A large bulb is transplanted every 3-4 years. The plant should be transplanted as rarely as possible, only if the bulb does not fit in the pot. In this case, the plant should be transplanted into a pot about 5 cm larger than the old one. The top of the bulb should be half the surface of the soil. In old plants, it is sufficient to replace the upper layer of soil a few centimeters thick in spring. |
| Features of care | If you need to get seeds, then after flowering, they are expected to mature on the peduncle. Otherwise, the flower stalk is cut off. It is recommended to wipe the leaves with a damp sponge. |
| Difficulties | Possible aphids, mealy moth, spider mites. Fight with insecticides. The bulb may rot. The leaves turn yellow and dim when the light is too bright, turn pale – with a lack of light (the false stem is stretched). The plant does not bloom if the bulb is still very small, or in a pot too much soil. A light coating on the leaves may appear as a result of watering with too hard water. |
