What are the cultivation methods and precautions for imported Amaryllis?

SummaryCultivation methods: Amaryllis is best planted in a loose, well-drained, slightly acidic medium. Before planting, remove decayed and dried fibrous roots while keeping healthy roots, and be sure to properly rehydrate the bulb. Disinfection is a key step in planting imported Amaryllis, and you must use a disinfectant in a certain proportion for disinfection. Precautions: Replace the potting soil every 1-2 years. When changing pots and soil, prune away withered leaves and dead roots, and carry out pest and disease control during the growing period.

I. Cultivation methods for imported Amaryllis

1. Clean the bulb

(1) Before planting, cut off the roots of the bulb that have already decayed or dried up, and keep the remaining healthy roots.

(2) If the outside of the bulb has multiple layers of brown dried skin, part of it can be peeled off to eliminate the hidden risk of rot as much as possible.

2. Rehydrate the bulb

(1) If the bulb has lost a lot of water due to long storage, it is best to properly rehydrate it, that is, soak the middle and lower part of the bulb in clean water slightly warmer than the ambient temperature for 1-2 hours.

(2) If you have relatively rich planting experience, you can appropriately add some plant hormones such as gibberellin to the water, which is beneficial for the bulb's later rooting and swelling.

(3) However, you should pay attention to the concentration of gibberellin and the soaking time, otherwise it will backfire and cause damage to the plant roots.

3. Disinfection

(1) Disinfection is the most critical step in planting imported Amaryllis. Generally, disinfectants such as carbendazim and chlorothalonil are used in a certain proportion for disinfection.

(2) Afterward, the disinfectant water is used for watering after planting so as to disinfect the soil.

4. Choice of medium

(1) Under limited planting space, the choice of medium is very important. Amaryllis is best planted in a loose, well-drained, slightly acidic medium.

(2) The recommended medium is peat : vermiculite : perlite = 2:1:1 or peat : perlite = 1:1. If this is inconvenient, ordinary humus soil can be used instead of peat, and river sand instead of perlite.

(3) It is best to mix 10% base fertilizer such as bone meal or superphosphate into the medium.

5. Deep planting

(1) When the bulb of an imported Amaryllis is first planted, more than half of the bulb should be exposed, and the condition of the bulb should be checked frequently.

(2) A newly planted bulb is very prone to rot. After this period has passed and the roots and leaves of the bulb have grown out, cover the bulb with soil up to one-half or two-thirds of its height.

II. Precautions for cultivating imported Amaryllis

1. Pruning

Amaryllis grows relatively fast, and its leaves are relatively long and dense. When changing pots and soil, the withered leaves, dead roots, and roots and leaves affected by pests and diseases should be cut off, leaving only vigorous leaves.

2. Replacing the potting soil

After 1 or 2 years of cultivation of Amaryllis, the fertilizer in the potting soil will become very scarce. In order to promote the growth and flowering of Amaryllis in the new year, new soil should be replaced in time.

3. Pest and disease control

(1) In order to make imported Amaryllis grow vigorously and bloom as soon as possible, pest and disease control should be carried out in time.

(2) Pesticide should be sprayed once a month, and spraying should be done at 9 a.m. or after 4 p.m. on sunny days. The sunlight at noon is relatively strong and is not suitable for spraying pesticides, so as to avoid pesticide damage.
