How to Select Northern Goldenrain Tree Seeds? A Detailed Guide to Seedling Cultivation Methods

Speaking of the Northern Goldenrain Tree, most people are probably quite familiar with it. It is a tree species commonly used for landscaping, tall and upright, growing very quickly, and relatively suited to being planted in northern regions. So how do you select Northern Goldenrain Tree seeds? What are the seedling cultivation methods? Friends who want to know, read on!

I. How to select Northern Goldenrain Tree seeds?

When planting the Northern Goldenrain Tree, you must select seeds strictly and carefully choose the highest-quality seeds, so that the survival rate is higher and the plants grow more vigorously. In addition, before sowing, Northern Goldenrain Tree seeds must undergo sprouting treatment: soak the seeds in warm water for about twenty-four hours, letting the seed coat absorb water and swell, so they can germinate faster and better.

II. Seedling cultivation methods for Northern Goldenrain Tree seeds

1. Sowing the Northern Goldenrain Tree

The sowing site should have loose, breathable soil with excellent water retention and drainage, a certain level of fertility, and no underground pests or pathogens. After sowing the seeds that have undergone sprouting treatment, cover them with a 1 cm to 2 cm thick layer of loose, fine soil, to prevent the seeds from drying out and losing water or being damaged by birds and animals.

2. Shading the Northern Goldenrain Tree seedlings

After the covering is removed, a shading frame should be set up promptly. The shading time and degree of shading should be determined according to the local temperature and weather conditions at the time, ensuring that the young shoots are not damaged by sunscald. Entering autumn, the light duration and light intensity should be gradually extended, until full light is received, to improve the lignification level of the young shoots.

3. Thinning and filling in of Northern Goldenrain Tree seedlings

When the young shoots grow to 5 cm to 10 cm tall, thinning should be carried out, leaving about 12 plants per square meter. Thinning of Northern Goldenrain Tree seedlings requires keeping the small and leaving the large, removing the inferior and keeping the superior, thinning the dense and keeping the sparse, with all seedlings evenly spaced, and it is best done on cloudy and rainy days. Combined with thinning, fill in gaps where plants are missing, to ensure the young shoots are evenly distributed.

4. Fertilizing Northern Goldenrain Tree seedlings

Fertilizing is an important measure for cultivating strong seedlings. After the young shoots emerge and grow roots, fertilize frequently together with watering. In autumn, stop applying nitrogen fertilizer and increase the application of phosphorus and potassium fertilizers, to improve the lignification level of the plants and enhance the cold resistance of the seedlings. In winter, apply farmyard organic fertilizer as a base fertilizer, which both provides sustained nutrients for seedling growth and plays a role in heat preservation and soil improvement.

III. What is the difference between the Northern Goldenrain Tree and the Southern Goldenrain Tree?

1. Northern Goldenrain Tree

Deciduous tree, up to 15 m tall, with a nearly spherical crown, grayish-brown bark, branches with rounded ridges, conspicuously raised lenticels, and no terminal bud. Odd-pinnate compound leaves alternate, with 7-15 leaflets, ovate or elliptic-ovate. Leaf margins coarsely serrate, often with deep lobed layers near the base, and the leaf surface dark green and smooth. Flowers yellow, in terminal panicles, flowering in June-July, fruit ripening in September-October. The pericarp is membranous and inflated, triangular-ovate and lantern-like, orange-red or reddish-brown when mature, and the seeds are round and black.

2. Southern Goldenrain Tree

Deciduous tree, 15-20 m tall, with a broad ovate crown. Leaves flat, twice odd-pinnate compound leaves, alternate, with 7-9 entire leaflets, 3-250px long. Bark dark gray with longitudinal fissures, and branchlets dark brown. Crown umbrella-shaped or spherical. Flowers golden yellow, in large panicles, capsule triangular-ovate, formed by membranous pericarp joined into a lantern shape, with the pericarp turning red in autumn. Flowering in August-September, fruiting in September-October.
