How to Care for Ulmaceae梅花 in Spring
As a common ornamental plant in northern gardens, the spring maintenance of Ulmaceae梅花 directly affects the plant's growth and flowering quality throughout the year. There are significant differences in management between the early spring germination period and the post-flowering period in late spring. Mastering the stage-by-stage maintenance skills can keep the pink flower sea blooming continuously on the branches.
Key Points for Spring Maintenance of Ulmaceae梅花
Intelligent Water Control to Maintain Soil Moisture
Mature plants should be watered once a week, while young plants need to maintain a watering frequency of 2-3 times. Using the 'soak pot method' can prevent waterlogging and root rot, and the timing of watering can be judged by observing the dryness of the topsoil 3 cm. When rainfall is abundant, drainage ditches should be dug to prevent the dual hazards of frost and waterlogging caused by late spring cold snaps.
Dynamic Light Control
In March and April, the plants can be exposed to full sunlight, but from May onwards, a sunshade net should be set up to control the duration of sunlight. It is recommended to use the 'morning light + evening sun' mode: remove the sunshade equipment before 9 am and after 4 pm, and use intelligent timing devices to manage the light cycle precisely, promoting flower bud differentiation.
Temperature Gradient Management
Set up a temporary greenhouse to deal with temperatures below 10°C, and start the atomizing cooling system when the temperature exceeds 25°C. Focus on protecting the plant from sudden temperature changes during flowering by wrapping the trunk with insulating cotton or covering the roots with pine needles to create a buffer layer, keeping the day-night temperature difference within 8°C.
Accurate Nutrient Supplement
Apply high-phosphorus water-soluble fertilizer (N-P-K=10-30-20) during the germination period, and switch to balanced slow-release fertilizer after flowering. Combine foliar spraying with chelated iron and borax solution to prevent yellowing of new leaves and falling of buds. Remember to apply thin and frequent fertilization, diluting the concentration to 70% of the instructions on the packaging.
By dynamically adjusting the four key elements in stages, the Ulmaceae梅花 plants can become more compact and the flowering period can be extended by 15-20 days. Special reminder: promptly prune the remaining flowers after flowering and thin out dense branches, and spray lime sulfur solution to prevent穿孔病, reserving energy for summer growth.
