Dawn redwood red blight: immediately after the plum rain season ends, spray the canopy with 1% Bordeaux mixture 4-5 times, once every 10-15 days, to control the occurrence of the disease. Tortricid moths: the best control period is the early stage of damage when the larvae emerge from overwintering (early to mid-April); 50% fenitrothion, 40% dimethoate, 80% dichlorvos and pyrethroid insecticides can be used; in dry seasons (July and August) when outbreaks occur

How to grow Dawn Redwood (Metasequoia glyptostroboides) from seed? A full breakdown of the key techniques

When the cone scales turn from green to yellowish-brown, crack slightly, and a small amount of seed falls out, the seeds are ready to collect. After the cones are collected, spread them out to air-dry or expose them briefly to the sun; the scales open and the seeds fall out. 2. Seed treatment: Before sowing, soak the seeds in cold water for 3 to 5 hours so they absorb water and swell fully, which aids germination and ensures even emergence. 3. Sowing: From late March to early April,

Dawn Redwood (Metasequoia glyptostroboides) Cutting Propagation Methods and Key Technical Points
Dawn redwood propagation by cuttings: from late March to early April, take cuttings and insert them immediately. Cut cuttings from 1- to 2-year-old seedling stock plants or from new shoots sprouted in the current year. Treat the lower end of the cuttings with naphthaleneacetic acid at a concentration of 0.5 per 10,000 (0.005%), soaking for 20 to 24 hours to promote rooting and improve survival. Insert about 120 cuttings per sq m. After insertion, keep the seedbed moist. New roots sprout in about 40 days; apply diluted human urine and manure once every 10 days, for 3 to 5 consecutive applications. In June, nitrogen fertilizer may be applied in small amounts several times, at 3 to 4 kg of urea per mu, diluted with water and poured on. In early August, apply phosphorus and potassium fertilizer once; per mu use
