How does mimosa breed?

Mimosa is a perennial herb or subshrub of Leguminosae. Flowers, leaves and pods all have good ornamental effects. Taproot plants have few fibrous roots, which are suitable for sowing and reproduction, and it is best to adopt the method of direct seeding to avoid root injury by transplanting. If transplanting is necessary, it should be transplanted in the seedling stage, otherwise it is not easy to survive. Let's take a look at how mimosa propagates.

Seed collection of mimosa

Mimosa pods are often clustered in one place, and the ripening period is very irregular. Mature and cracked pods, young fruits and flower buds often appear on a branch at the same time. Seeds should be harvested in batches, usually seeds from early pods in the middle and lower parts of branches.

Mimosa sowing time

The mature, full, large, full and colorful seeds should be selected before sowing, and the germination and preservation period of the seeds is relatively short, so they should be kept in a cool indoor place with picking and sowing or mixing fine sand, and should be sowed in the following spring, generally sowing indoors in early spring.

The sowing method of mimosa

The main results are as follows: 1. Mimosa can be directly seeded in a small pot or raised and planted in a shallow pot. the sowing soil is prepared with 20% rotten leaf soil, 30% garden soil and 50% fine yellow sand after sieving and mixing. when sowing, put an appropriate amount of culture soil in the basin, smooth and compaction, spray water with a spray pot, sow immediately after all the water permeates, sow 1-2 seeds in each pot, and sow seedlings in a shallow pot at a distance of 2 × 2 cm.

2. Cover the mimosa seeds with 3cm soil after sowing, cover the seeds with glass or plastic film to moisturize the basin, put the basin in a place of astigmatism of about 20 ℃, and then irrigate the basin soil with soaking method when the soil is dry. After about 7 days, the seeds germinate and seedlings emerge.

Management of mimosa at seedling stage

1. After the emergence of mimosa, the cover on the pot should be removed and the sun should be accepted gradually. When the seedlings grow to 3 cm high, the seedlings sown in the shallow pot can be divided and transplanted, and the seedlings should be transplanted with soil, otherwise it is not easy to survive. After watering the seedlings in the pot, put them in a semi-shady place, wait for the seedlings to slow down, and then move to a sunny place.

2. the direct seeding of mimosa in a small basin can grow directly in a sunny place, and the seedling pot can be moved out of the outdoor for cultivation in the middle of April and early May in the north, and the pot soil can be kept moist by watering in time. When the seedlings grow to 4 leaves, they begin to apply liquid fertilizer. Generally, the seedlings can be topdressing once for 7-10 days, and the pots can be changed again after the seedlings grow up, but the pots should not be too large. Generally, they can be planted in medium-sized flowerpots of 15-20 cm.
