The planting depth of perfume lily bulbs should be determined according to the specific planting environment and the size of the flower pot. It cannot be generalized as shallow planting or deep planting. Here are some specific suggestions: 1. Planting in flower pots
1. Flower pot selection: Choose a large-diameter flower pot with a depth greater than 15cm and drainage holes at the bottom to ensure sufficient growth space and good drainage conditions for lily bulbs.
2. Planting depth: - If it is a small flower pot with limited space, it is recommended to plant shallowly to avoid burying the bulbs too deeply, which may cause difficulty in germination- If it is a large flowerpot or directly planted, the planting ball can be buried slightly deeper, but it is generally not recommended to exceed 2-3 times the diameter of the planting ball. A depth of about 5-8cm is more suitable.
3. Soil requirements: Loose, well drained, and rich in organic matter soil should be selected, which can be commercially available floral soil or self prepared (such as garden soil, perlite, humus soil, etc.). 2、 Ground planting
1. Planting depth: When planting on the ground, the planting ball should be shallowly buried in the ridge soil, with a soil cover thickness of 1-2 times the diameter of the planting ball, generally 5-8cm thick.
2. Spacing requirement: Due to the tall and vigorous growth of lily plants, sufficient spacing needs to be reserved between bulbs to avoid planting too densely. The recommended spacing between ground plants is 30-60cm to ensure the growth space and ventilation and light transmittance of the plants.
3. Soil treatment: Before planting, the ground should be deeply plowed and excavated to a depth of about 15-20cm. If the soil is compacted or poorly drained, river sand, coal slag, or ceramic particles can be added to increase permeability, and an appropriate amount of fermented organic fertilizer can be applied to improve soil looseness and fertility. 3、 Precautions
1. Light and temperature: perfume lily likes sufficient light, but avoids strong direct sunlight. Maintaining a growth temperature between 15-25 ℃ is more suitable.
2. Water management: Keep the soil moist but not waterlogged, following the watering principle of "see dry, see wet". Avoid directly pouring water on the bulbs to prevent them from rotting.
3. Fertilizer application: During the growth period of lilies, nitrogen phosphorus potassium compound fertilizer or liquid fertilizer can be applied in moderation. When the flower stalk is pulled out and the flower buds are formed, phosphorus and potassium fertilizers can be applied to promote flower bud differentiation and bright colors.
4. Disease and pest control: Regularly inspect plants, take timely biological or chemical control measures when diseases and pests are found, and maintain plant health.
The planting depth of perfume lily bulbs should be adjusted flexibly according to the actual situation, not only to ensure that the bulbs have enough space for growth, but also to avoid adverse effects caused by too deep or too shallow.
