How to Grow Alstroemeria? Detailed Guide to Cultivation Methods and Precautions

Alstroemeria may be very familiar to many flower enthusiasts, because it is a relatively common flowering plant in daily life, and it has a long history. The flowers of Alstroemeria look a bit like daffodils and a bit like azaleas, with bright colors, very beautiful and charming. Nowadays, Alstroemeria has become a particularly common household decorative flowering plant. So do you know how to plant and care for Alstroemeria?

How to grow Alstroemeria

1. Soil: The planting site for Alstroemeria should be a fertile sandy loam with good permeability, with a soil layer thickness of 50 cm or more, and good drainage. The most suitable soil for Alstroemeria cultivation is slightly acidic, so according to the physical and chemical properties of the soil, adjust the pH to around 6.5.

2. Water: During the vigorous growth season, Alstroemeria should have sufficient water supply and relatively high air humidity, with relative humidity controlled at 80-85% as more suitable. In hot summer, it is in a semi-dormant state. When the temperature is lower in winter, attention should be paid to controlling water.

3. Fertilizer: When planting Alstroemeria, in combination with improving the physical and chemical properties and structure of the soil, a large amount of decomposed organic fertilizer should be applied, such as barnyard manure, preferably 30-40 kg per sq m, or an appropriate amount of superphosphate may be added as a supplement. Throughout the entire growth and development cycle of the plant, base fertilizer alone cannot meet the needs of growth and development, so topdressing should be applied at different growth stages as needed.

4. Temperature: Within 1 to 2 months after planting, giving Alstroemeria an appropriate low temperature (not lower than 5°C) is very beneficial for root rejuvenation and plant recovery. During the growth season, maintain the temperature at 8-15°C, and in summer it is best to keep the soil temperature at around 20°C. The most suitable temperature for flower bud differentiation of the plant is 20-22°C. In summer, in order to prevent the soil temperature from being too high, water supply pipes, perlite, etc. can be buried underground to achieve the purpose of cooling.

5. Light: Alstroemeria is a strongly sun-loving plant, and there should be sufficient light during the growth season. Its optimal sunshine duration is 13-14 hours. In winter and early spring, the natural sunshine time is short, so supplemental lighting should be provided during protected cultivation. In order to save energy, the supplementary lighting time should be chosen when the plant has entered the vigorous growth stage. Supplement light for 4-5 hours per day, and stop supplementary lighting once the natural light reaches about 13 hours.

Alstroemeria Cultivation Methods and Precautions

1. Pot and soil selection

For potted Alstroemeria, you can choose a 12cm-15cm flower pot, and repot as the Alstroemeria grows. For the soil, it is best to choose a loose, fertile, well-drained, slightly acidic soil. Mixing leaf mold or peat soil with garden soil and coarse sand will do.

2. Light and temperature

Alstroemeria likes sunlight, and sufficient light is needed during the growth period. Insufficient light will affect the plant's growth and flowering. In early spring, late autumn, and winter when sunshine time is short, supplemental lighting measures can be taken. In summer when the sunlight is too strong, in order to avoid sunscald, shading can be carried out. The suitable growth temperature for Alstroemeria is between 15°C——25°C. It likes warmth, is not cold-tolerant, and in summer is also not heat-tolerant, needing a cooler climate. Keeping the temperature above 10°C in winter allows it to overwinter safely. When the summer temperature is too high, it easily enters dormancy, and ventilation and water spraying need to be strengthened to cool it down.

3. Water and fertilizer management

Alstroemeria likes moisture, and during the growth season it needs sufficient water supply and relatively high humidity. In summer it will be semi-dormant, and in winter when the temperature is low it will also enter a dormant state, so water needs to be controlled, kept dry, and watering may even be stopped. Note that the humidity in the pot must not be too high. Fertilization should be moderate. In addition to applying sufficient base fertilizer at planting, topdressing is also needed during the vigorous growth period, generally applying nitrogen fertilizer to promote growth; applying potassium fertilizer during the flowering period; and during the high-temperature period in summer, the frequency of fertilization should be reduced.

4. Precautions

The main disease of Alstroemeria is the harm of root rot, and chemicals need to be sprayed. The main pest is aphids, and timely pest control is needed.

The flowering period of Alstroemeria

The flowering period of Alstroemeria is generally consistent with other flowers, all between May and July each year. When Alstroemeria blooms during the flowering period, the scene is very spectacular, and the flowers are elegant and delicate, deeply loved by people. The flowers of Alstroemeria are somewhat like the shape of azaleas but also like the shape of daffodils, making them somewhat difficult to distinguish.

Growth habits of Alstroemeria

Alstroemeria likes dryness and is afraid of excessive rain and too high groundwater levels. The soil requires good drainage and aeration, loose and rich in humus, with pH 6-PH 6.5 as suitable. The suitable growth temperature is 13C-21°C, among which 13C-15°C is optimal for rhizome enlargement, and growth is poor when the soil temperature exceeds 20°C. The suitable temperature for seed germination is 11°C. Before sowing, place the seeds under high temperature conditions of 26-31°C for one month, then move them to the suitable temperature conditions for germination, which is more conducive to germination. It is sensitive to day length response; long-day conditions can promote flowering and increase the number of flowers, while short-day conditions inhibit flowering.

Through the above content, I believe everyone has gained some understanding of the planting and care methods for Alstroemeria. Alstroemeria flowers are beautiful, and whether placed on a balcony, in a courtyard, or indoors, they are all very good choices! Friends who like them should not hesitate, hurry and add another touch of color to your home!
