Propagation methods of Impatiens balsamina

Impatiens can not only be used to dye nails, but also can be watched as a potted plant. Impatiens growing in the wild generally reproduce the next generation by self-sowing, but as a potted plant, how can impatiens reproduce? Today, the editor will share with you the breeding methods of impatiens.

Impatiens has a certain drought tolerance, but cold tolerance is relatively poor, so it also likes sufficient light, and the requirements of the basin soil is not very strict, usually use sandy loam with good permeability. Impatiens is mainly bred by sowing, and the germination rate is also relatively high.

However, impatiens seeds should be harvested in time when they are ripe, otherwise the seeds will be ejected from the seed clip and not easy to collect. Generally, it can be harvested in time when the pericarp outside the seed is slightly yellow. And the vitality of the risk flower is tenacious, and the germination rate can be achieved 100% after a little selection and sowing. And even if it is taken out and sown after 4-5 years storage, the germination rate is still relatively high.

Impatiens is usually sown in mid-early April in spring, and then covered with a layer of culture soil about 0.3-0.4 cm thick. Pay attention to shading and moisturizing during the period, and if it goes well, it can sprout after a week. When the seedlings pull out 2-3 leaves, they can carry out transplanting with soil. On the other hand, the planting in the pot in the real sense can also be carried out according to the growth status of seedlings in the later stage. If the late maintenance management is scientific, it can begin to bloom in June in summer.

In addition to sowing and propagation, impatiens can also breed seedlings by cutting. However, compared with the sowing and breeding method, the requirements of cutting are often much higher, but the survival rate is relatively lower. Therefore, the sowing method is generally used to propagate seedlings. In order to improve the survival rate of cutting, cutting conditions should be met, cutting methods should also be scientific, and maintenance and management also need to pay more attention.

Impatiens cutting can be completed with the help of seedling hole plate, the culture medium can use sawdust, vermiculite, peat ash, and then prepared according to the proportion of 3:3:4. After that, the sturdy branches are cut from the mother plant as cuttings, but more than 3 nodes are required on the cuttings to ensure that they can sprout after rooting.

The cuttings of impatiens should use fluvo-aquic soil. After gently inserting the cuttings into the substrate, the original should be watered in time. At the same time, after watering, chlorothalonil should be sprayed every half an hour for 10 minutes to moisturize the leaves. Usually, in addition to doing a good job of replenishing water, you should also avoid direct sunlight before taking root and sprouting. It will take up to 2 weeks to take root.

When the seedlings grow to a height of about 10 centimeters, we should pick the heart or hit the top in time. Only 2-3 nodes need to be retained on the main branch, which can promote the seedling to sprout more lateral branches, by using this method, until the seedling grows to its satisfaction. Usually after more than 3 months, the seedlings will gradually grow up and form a relatively complete crown.
