The toon tree, as a unique tree species in China, many people only know to eat toon, not many people really know the species of the tree. In the past, the fragrant toon is in the form of afforestation of large-scale planting, and this is also in recent years in the form of vegetables to find out the experience. Types of Fragrant Trees:Fragrant toon trees are generally categorized by their leaves, which can be divided into purple toon and green toon.

Purple toonberry:The trunk is lush and open, the bark is gray-brown, and the buds are purple-brown. When germinating, the buds are glossy and shiny with strong aroma. With less fiber and more oil, the quality and appearance are especially good, and it is also a popular variety in the market. Green toon:The trunk is upright, the bark is green or green-brown, the buds are lightly scented, the surface of the leaves has less oil and no light, and the quality is poor. Toon used to be planted trees. Many villagers from all over the world picked seeds from a small area in front and behind their houses in the hope of planting them and using them as timber. And the toon grows slowly, the trunk is branched, the tree is easy to bend, the yield of buds is not very high, and there are not many large areas planted.

Toon on the soil requirements:Toon tree wood root system is very developed, the adsorption capacity in the soil is particularly strong, the adaptability of the soil is also very strong. Many places in China have traces of toon trees (except a few places in the northeast and northwest). For soils rich in calcium and organic matter, the toon tree grows best. If it is in poor soil structure and poor sandy soil, it can also grow, but the growth is slow, the quality is poor, the tree grows irregularly, and it is easy to decline early. Toon tree wood is not very strict on soil ph requirements, can grow in acidic, neutral and slightly alkaline soil.

Toon tree light requirements:Toon tree is sun-loving plant, need direct sunlight, intolerant of shade. Toon buds grow in sunny planting area, with bright color, strong aroma, early bud stage, early market, and good specificity. Toon in the case of insufficient light, light time is short, the tree's buds are mostly green, light taste, light aroma, rich in water content, fiber, germination is much slower. Branches are slender, branches grow upward, and the crown does not open. Toon tree wood water requirements:Toon tree wood like warm and wet soil, afraid of waterlogging. The roots of the tree have a strong root system and are highly resistant to drought. When planting toon tree seedlings, the root system is not very developed and perfect, so the seedling period needs to keep the soil moist, which is conducive to the rapid rooting of toon tree seedlings.

The toon tree wood is afraid of stagnant water and does not tolerate flooding. If there is stagnant water for a short time, it should be discharged in time. For too long, the roots will not be able to breathe in the soil, wither and rot and die. If the water content of the soil layer is too high for a long time, the root system is prone to disease, and the high water content will directly affect the taste and flavor of the spring buds. Temperature requirements of toon tree wood:Toon tree wood is native to temperate plants, adapted to warm and humid climate. When the temperature is between 10-30, the toon tree wood can germinate and grow normally. When the temperature is below -10, seedlings and young plants will freeze and frostbite. With the successive cuttings propagation of Toona sinensis, the tree's cold resistance increases with the age of the tree, and it can withstand the lowest temperature of -25℃. The temperature difference between morning and evening is greater for toon, and the toon bud has a stronger flavor and aroma. Comparatively speaking, the greenhouse planting of toon in the north, the temperature difference between indoor and outdoor is too large, which makes the toon bud slightly better than the south in taste.

Toon, as a unique tree species in China, is the only country that treats toon/as a vegetable species. Southeast Asian Chinese are influenced by their dietary habits and eat a lot of toon sprouts. There is still a big market for growing toon trees.
