How to grow Dutch daffodils
Dutch daffodils have become the new favorite of gardening enthusiasts because of their elegant flower appearance and rich fragrance. Mastering scientific planting methods can allow bulbous flowers to show their best condition. This article provides guidance from seed ball treatment to post-maintenance, and analyzes key technical points with practical pictures. Pretreatment techniques for Dutch narcissus cultivation and preparation of bulbs High-quality bulbs have tan skin. Use tweezers to gently peel off the dry scales on the outer layer and retain the fresh bulbs on the base 3-4 layers. Use disinfectant scissors to cut the aged root system at the bottom and retain a new rooting point 0.5 cm above the root disc. The diameter of the treated seed ball should be maintained at least 6 cm. The double disinfection plan uses pre-immersion in warm water at 50 ° C for 30 minutes to activate dormant bud spots, and then soak them in 0.1% potassium permanganate solution for 90 minutes. Specially treated mildewed seed balls can be coated with carbendazim powder, and placed on a hollow grid frame to ensure ventilation at the bottom when drying. Narcissus soil ratio plan, substrate scientific ratio, ideal ratio is peat soil: perlite: humus soil =5:3:2, and 500g of bone meal is added per cubic meter to adjust the pH value. In southern regions, it is recommended to mix 10% rice hull charcoal to prevent root rot, and potted plants need to lay a 3 cm ceramsite drainage layer on the bottom. The precise planting specifications for the entire process of daffodil planting adopt the principle of "shallow burial and deep protection". 3 seed balls are planted in 20-cm diameter pots, keeping the bud points facing upwards. The thickness of the soil cover is 1.5 times the height of the seed ball. A growth space of 5 cm needs to be reserved from the root disc to the bottom of the pot. After planting, root-fixing water must be poured thoroughly. Key points of environmental control should maintain a low temperature of 12-15℃ during the germination period to promote roots, and increase it to 18-22℃ after buds appear. Ensure 4 hours of direct light every day, control the air humidity at 60%-70%, and use the dipping basin method to replenish water to avoid stagnant water in the leaf heart. Extend the flowering period and manage the flowers after they die, cut off the remaining flowers in time to retain the leaves, and apply phosphorus and potassium fertilizer topper every half of the month. Pilling storage during summer dormant period needs to be wrapped in vermiculite and maintained in a low temperature environment of 5 ° C until autumn planting. Flowering can be restored for three consecutive years through scientific rotation.
Follow this guide step by step to form a complete cultivation system from ball treatment to flowering management. Reasonable combination of soil structure and light control can allow Dutch narcissus to bloom continuously for 20-25 days, creating a dream spring flower landscape.
