How to maintain Drimiaundulata of wrinkled bulbous plants

Drimia undulata, Hyacinthaceae, Drimia, originated in South Africa, likes cool, moist and sunny environment, and is afraid of damp heat, semi-shade, drought and cold tolerance. It has the habit of dormant at high temperature in summer and growing in cool season from autumn to spring.

Wrinkled bulbs are perennial bulbous succulent plants of the genus Hyacinthaceae, with round or olive-shaped bulbs. The bulbs are composed of layers of thick fleshy scales, the epidermis of the underground part is yellow and white, and the scales exposed to the soil will dry up after exposure to the sun. The fleshy leaf is drawn from the top of the bulb and is semicircular. There is a hard stem in the middle of the leaf. The leaf is narrow and long, and gradually wrinkles and waves grow, much like narrow kelp. The wave folds on both sides of the leaf are more uniform and will fall down as it gets higher and higher.

The wrinkled bulb root likes cool and afraid of heat, and the main growth period is from September to April of the following year, and the temperature should be kept at 5 ℃ to 20 ℃ in winter. In this environment, the plant can continue to grow and can carry out normal fertilizer and water management. If watering is controlled to make the plant dormant, no less than 0 ℃ can safely survive the winter indoors. In the middle and last ten days of May, with the increase of temperature, the leaves on the ground gradually withered, the plant went into a dormant state, the dry leaves could be removed, the bulbs were left in the original pot for summer, and the flowerpot should be placed in a dry, ventilated and water-free place until the end of August and the beginning of September. As the weather turns cool, new buds will grow from the bulbs, and normal management can be slowly restored. It is worth reminding that summer dormancy, plants do not have no water throughout the summer, can stay slightly moist, although the leaves have dried up. Underground bulbs will still grow, do not water in the center of dry leaves, over a summer, the bulbs grow a lot bigger.

Wrinkled bulbs like light, should be given sufficient light during the growing period, if the lack of light will make the leaves weak, and the degree of fold is poor, it is difficult to highlight the unique charm of wrinkled bulbs. The leaves of plants growing in sufficient sunshine are narrow and long, with high ornamental value, but sunshade nets should still be built after April to avoid hot sun exposure and prevent leaf tips from drying up.

Wrinkled bulbs like a humid environment, and it is appropriate to keep the soil moist during the growing period. If there is a long-term drought and lack of water, the plant will not die, but the growth will stagnate, the leaves will yellowing, and even withered; while long-term stagnant water in the basin soil will cause bulb rot. Water can often be sprayed to the plant to increase air humidity and prevent the top of the leaves from drying up. In summer, in order to avoid flooding in the rainy season, the flowerpot can be placed on the shelf or on a stage with a certain height, and pay attention to control watering to prevent the bulb from rotting due to stagnant water, but the pot soil can not be completely dry to prevent the bulb from drying up.

The peak period of plant growth is from October to April of the following year, and the mature thin liquid fertilizer or compound fertilizer is applied once a month to provide sufficient nutrients and make the plant grow vigorously.

Wrinkled bulbs can be artificially cross-pollinated after flowering to make the plants bear fruit, and the seeds should be harvested after maturity so as not to scatter them; wrinkled bulbs are generally changed once a year at the end of August (because the long bulbs can be changed once every 2 to 3 years). The basin soil requires fertile and loose, rich in humus, and has good drainage and air permeability. it can be prepared with 3 parts of rotten leaf soil or peat soil and 2 parts of vermiculite or sandy soil. The editor used peat mixed with cinder, added a small amount of perlite vermiculite, and laid river sand on the soil surface. Cut off the rotten root system when changing the basin, plant the bulb out of the soil 1 / 3 or so, pour water after planting, keep the soil moist, and wait for new leaves to grow from the top of the bulb. you can see the sun step by step.

Wrinkled bulbous roots can be propagated by sowing and ramet, a variety with lateral buds.

Sowing: this method is suitable for mass reproduction and is carried out in autumn. After sowing, it is covered with thin soil and covered with glass to keep the soil and air moist and has a high emergence rate. After sowing and at the seedling stage, in order to avoid flushing the seeds or seedlings out of the soil during watering, you can soak the soil slowly by soaking water from the drainage holes at the bottom of the flowerpot. The detailed sowing refers to the seeding paste of the editor.

There are not many diseases and insect pests in wrinkled bulbs, and the main pests are snails and nematodes in the soil. When planting, the soil can be treated with high temperature to kill pests and eggs in the soil, and insecticides such as carbofuran can also be mixed into the cultured soil.
