When the blue-purple flower spikes bloom in spring, hyacinths always become the most eye-catching scenery on the balcony. Many flower enthusiasts are curious whether this bulbous plant is suitable for soil cultivation. In fact, soil cultivation can not only extend the blooming period but also enable the bulbs to continue flowering. Today, we will thoroughly analyze the correct approach to soil cultivation of hyacinths, from selection to maintenance.
Core Advantages of Soil Cultivation for Hyacinths
Compared to the brief blooming of hydroponic hyacinths, soil cultivation can achieve a continuous flowering period of 2-3 years. The soil environment is closer to the native growing conditions, providing a continuous supply of nutrients, allowing the bulbs to fully recover after flowering. However, it is important to control soil moisture and regularly check for mold growth.
Key Indicators for Bulb Selection
High-quality bulbs should have a diameter of 5cm or more, with intact and undamaged skin, feeling heavy in the hand. Gently pressing the bulb with the thumb, those with strong resilience are the most active. Special attention should be given to discarding bulbs with brown spots, which may be early symptoms of soft rot.
Golden Formula for Soil Mixture
The mixed matrix is recommended to use peat soil: perlite: decomposed leaf soil in a ratio of 5:3:2, with a 2cm thick layer of ceramsite at the bottom to enhance drainage. Sandy soil should be controlled to less than 30%, as too much will result in insufficient water retention. Incorporate 50g of bone meal as a base fertilizer per cubic meter of soil.
Step-by-Step Planting Guide
The planting depth should be twice the height of the bulb, with the top bud point exposed. For the first watering, it is recommended to use the immersion method and stop immediately when water seeps out from the bottom of the pot. In a semi-shaded environment at 15°C, new roots usually emerge within about 14 days, at which time scattered light can be gradually increased.
Key Points for Maintenance Cycle Management
Keep the soil slightly moist during the germination stage, and apply phosphorus-potassium liquid fertilizer every 10 days after the flower stalks emerge. Keeping the temperature at 18-22°C after flowering can extend the blooming period. After flowering, cut off the残花 (withered flowers) and retain the leaves, continue to maintain until natural withering in summer, at which time harvest the bulbs and store them in a refrigerator.
Mastering these soil cultivation techniques, you can enjoy the intoxicating beauty of hyacinths year after year. Whether creating a window sill garden or a mixed container, soil cultivation can make hyacinths display more enduring vitality. Start preparing the bulbs now and look forward to the blooming next spring!
