What are the planting methods and precautions for gentian?
Gentian is an ornamental herbaceous plant. It likes moist environments and has certain requirements for soil, preferring acidic soil. Because its flower colors are quite brilliant and colorful, many people like it, but friends who want to grow it do not know the methods, nor do they know what precautions are needed. Let's introduce them below.
How to grow gentian
After the seeds sprout into seedlings, unhealthy seedlings and those with weaker growth can be pulled out, leaving thicker and stronger seedlings for cultivation. During the seedling stage, weeding should be done frequently. They can be pulled out directly; do not let weeds absorb soil nutrients and cause seedlings to lack nutrients. Even less should you wait until the weeds grow large before removing them, as this can easily damage the roots of gentian grass.
If the soil cracks or clumps, loosen the soil in a timely manner. When loosening the soil, be careful not to go too deep, otherwise it is easy to damage the seedlings and also bring the seedlings out of the soil. Loosening the soil can also be combined with transplanting and setting out. After transplanting, loosen the soil another 2 to 3 times. After transplanting, apply one topdressing, which can be done by spraying to fertilize the leaf surfaces. Apply another topdressing at the bud stage and at flowering and fruiting. Over 3 to 4 years, the soil can be fertilized once; after fertilizing, level the soil.
Gentian planting methods and precautions
1. Soil selection: choose relatively moist, organic-rich sandy soil.
2. Environment selection: gentian grass likes abundant sunlight, so choose a place where sunlight can shine directly.
3. Preparation before planting: base fertilizer should be sufficient, then level the soil surface and make furrows for planting gentian grass.
4. Flower thinning and bud removal: for fruiting plants, if the number of flowers far exceeds the number of fruits, prune and remove them in time to avoid consuming unnecessary nutrients. If not pruned and removed in time, the fruits that finally form will also drop before reaching full formation.
5. Precautions: pay attention to the prevention and control of damping-off, leaf spot, and brown spot diseases.
Gentian propagation methods
1. Seed propagation
Gentian seeds are very small, and the seeds need to germinate in a place with relatively good warm, moist, and light conditions. The seeds can germinate in about one week at around 25 degrees. During the seedling stage, growth is relatively slow, and strong light exposure should be avoided at this time. Strengthen management during the seedling stage, keep the seedbed moist, and use reed curtains for shading.
2. Root division propagation method
In autumn, dig out the underground roots and rhizome parts, and do not damage the winter buds. Cut the rhizomes into stem segments with three or more nodes, bury them in the soil, then cover with soil, water, and keep the potting soil moist.
3. Cutting propagation method
Before flower bud differentiation, cut branches from mature plants, and cut off the lower leaves of the branches to reduce evaporation. After inserting the cuttings into the cutting seedbed, water immediately to moisten them. When the temperature of the potting soil is between 18-28 degrees, roots can form in three weeks.
How to make gentian bloom on New Year's Day
1. Adjust temperature
Generally, temperature adjustment is a relatively effective method, and it is also relatively convenient to adjust. Compared with using chemicals for adjustment, it also does not harm the plant, so this is the preferred measure. First, if you want the plant to bloom, then you cannot continue to leave it outdoors.
Then, we must judge according to the specific situation exactly how to regulate the temperature. If you feel it will bloom before New Year's Day arrives, then appropriately lower the temperature to delay its flowering date; if New Year's Day is about to arrive and there is still no sign of full bloom, then appropriately raise the temperature to advance its flowering period a little.
2. Water and fertilizer regulation
The principle of this method is also relatively easy to understand: it regulates the flowering period by adjusting the plant's external environment (meaning water and nutrients). If the plant would bloom before New Year's Day, then reduce the amount of watering and fertilizing to delay the flowering period.
Conversely, provide as much water and nutrients as possible. This method is also relatively easy to implement, but compared with the first method, its effect is not very obvious. Therefore, we can consider combining it with other methods.
It seems that growing gentian is not as difficult as imagined. Usually we generally use the sowing method to plant it. When planting, as long as disease and pest prevention and control work is done well, it is fine. However, if you want to control the flowering period of gentian, you still need to put in some effort. The regulation of temperature and water and fertilizer is key.
