How to Care for Freesia
This article provides an overview of how to care for freesia and the cultivation techniques for this green ornamental plant. Let's learn about it together.
The general planting time for freesia is from May to June and from September to October. When planting freesia, it is important to choose fertile and well-draining acidic soil, which can effectively improve the survival rate of the plant. After planting, ensure adequate fertilization and lighting to promote robust growth.
1. Planting Methods for Freesia
1. Soil
When planting freesia, it is necessary to prepare the soil, choosing well-draining and breathable soil rich in nutrients. Sandy soil can be used, or a mixture of potting soil and humus soil in a 1:1 ratio can be prepared.
2. Bulb Selection
Choose high-quality and healthy bulbs to increase the survival rate of freesia. Avoid bulbs with diseases or damage from pests, as these can affect survival rates.
3. Planting
The general planting time for freesia is between May to June and September to October. Before planting, disinfect the bulbs. After planting the bulbs in the soil, cover them with a layer of 1-2 centimeters of soil, making sure to leave the leaves and cut ends exposed.
4. Mulching
After planting the freesia bulbs, use some weeds to cover the roots, which is beneficial for the growth of the plant.
II. Management After Planting
1. Temperature
The bud differentiation of freesia in the later stages of planting requires a temperature range of 8-13 degrees Celsius, while the temperature during the bud development stage should be controlled between 13-18 degrees Celsius. Temperatures below 18 degrees Celsius can delay flowering. High temperatures can cause the plant to bloom early, making the growth weak.
2. Fertilization and Watering
After planting the freesia bulbs, ensure they receive adequate nutrition and water. Apply organic liquid fertilizer every two weeks, or use an appropriate amount of compound fertilizer. Water the bulbs properly, keeping the potting soil moist without积水 or excessive dryness, following the principle of watering when dry and not watering when wet.
III. Propagation Methods for Freesia
1. Bulb Division
Bulb division is one of the common methods for propagating freesia. After the plant withers, dig out the corms. Although the mother bulb has died, new smaller bulbs will grow on top, which can also bloom when planted. The daughter bulbs will enter a dormant period in high temperatures, so after digging them out, they should be dried and stored in a well-ventilated place.
2. Seed Propagation
Freesia can also be propagated by seeds, which usually mature in May to June. Harvest the seeds at this time. After harvesting, you can immediately proceed with sowing, with the germination temperature around 15-20 degrees Celsius. Sow the seeds in a greenhouse, and once the seedlings emerge, use containers for cultivation, maintaining a room temperature of 15-18 degrees Celsius, and providing appropriate water and fertilizer. By the following May to June, they can be transplanted as flowering bulbs.
