The most critical medicinal part of the stegophylla dracaena tree is its "dragon's blood", that is, the sap that flows from the branches. This bright red sap is actually the resin of dracaena, and its branches are in contact with the outside air, and the substances in the air undergo a plant immune reaction, and finally produce a red liquid resin catalyzed after plant self-defense, which is known as "blood exhaustion".

Key points for the conservation of dracaena
1. Dracaena plants are divided in size, so the maintenance methods are slightly different. Larger dracaena trees are very suitable for placing in the living room and larger corridors, and if there is a garden, it is best to plant one on the ground. The small dracaena tree is more suitable for offices, study and other places, placed on the desk, the decoration is still very good-looking.
2. Dracaena originated from tropical areas abroad, and its adaptability to light is relatively good. Daily should be placed in a place with sufficient light to maintain, semi-shade environment can also grow, but it is best to maintain more than 2 hours of scattered light every day, but the sunlight can not be too strong, as long as sufficient light can be ensured during the growth period, too strong sunlight is easy to burn the leaves.
It is worth noting that although dracaena is shade-tolerant, it cannot often be placed in a shady corner, and its green leaves are prone to yellowing or even withering in the long run. The more suitable growth temperature of dracaena is between 20 and 28 degrees, if it is lower than 10 degrees in winter, it is necessary to do a good job of keeping warm from the cold.
3. As a tropical plant, dracaena's water demand is not very high, so we can't water too much or too often with daily watering, too much water will make its root system rot. Generally, in spring and autumn, you can water 1-2 times a month, and then water after the potting soil is dry, and you do not need to water when it is wet, otherwise it will accelerate its death.
4. Dracaena is a plant suitable for growing in a warm environment, more cold-resistant, light-loving but unable to withstand scorching sun. Therefore, a warm but not hot climate environment is the most conducive to growth, and spring and autumn are the best growing periods.
5. Soil and fertilizer, we can choose humus soil mixed with a certain proportion of sand, so that the soil has good air permeability and contains certain nutrients, which is more suitable for the growth of dracaena. When planting dracaena, we can also place some bottom fertilizer at the bottom, which can help the roots of dracaena absorb nutrients and increase the growth rate.
The choice of fertilizer, dracaena tree to choose phosphorus and potassium mixed fertilizer is more appropriate, this fertilizer can provide the necessary growth elements of plants, accelerate their growth rate. Fertilizer can not be too concentrated, and one point to pay attention to is that when fertilizing dracaena, it is necessary to use less nitrogen fertilizer and more phosphorus and potassium fertilizer to avoid excessive nitrogen fertilizer.
Dracaena is a slow-growing plant, so we can't fertilize it frequently, especially some quick-acting fertilizers with plenty of nutrients. It is also good that a little well-rotted organic fertilizer can be properly buried in the roots, which is very beneficial for root growth and also prevents potting soil compaction.
6. The dracaena tree has lush branches and leaves, so proper pruning is still necessary, so that the appearance of the dracaena tree is more beautiful and the appearance is higher. For pruning, we can trim the leaves with a longer bottom and cut the top flat. During the growth of dracaena, cut off branches with poor growth, yellow leaves, over-dense and infected with pests and diseases. Pruning in this way is conducive to the later growth of dracaena, which can make the whole plant grow dense and the leaves more emerald.
