Specifications These premium Toona sinensis seeds are strictly cleaned and screened to filter out shrunken, cracked and immature grains for stable germination. This fast-growing deciduous tree bears compound pinnate leaves. The new young sprouts in early spring are reddish and carry a unique rich aromatic flavor. Seeds are flat and winged, and they lose viability quickly if stored for too long. Mature trees develop an upright spreading canopy and can reach considerable height over years.
Product Advantages Toona sinensis provides dual value as edible vegetable and landscape tree, making it a special edible deciduous tree species. It can be harvested for fresh tender shoots every spring after establishment. Pair it with other edible tree seeds to create your perennial edible garden.
Planting Method Step 1: Timing. Sow in early spring. Optimal soil temperature for germination is 15–22°C. Fresh seeds are strongly recommended. Step 2: Site preparation. Choose a sunny or lightly shaded spot with deep, loose, well-drained soil. Remove weeds and mix compost into soil. Step 3: Seed pre-treatment. Soak seeds in warm water for 12 hours, then keep moist at 20–25°C to accelerate germination. Step 4: Sowing. Plant seeds 0.5–1cm deep in seedbed. Keep seed spacing around 5cm. Step 5: Water after sowing. Mist gently to keep soil slightly moist; avoid waterlogging. Step 6: Seedling emergence. Seedlings emerge in 10–20 days. Protect young seedlings from strong hot sun. Step 7: Transplanting. When seedlings grow 3–4 true leaves, transplant. Space trees 2–3 meters apart. Step 8: Maintenance. Water regularly in the first year. Prune the top of the tree to encourage more side shoots for harvesting tender sprouts.
