How to plant purple loosestrife? Detailed planting methods and tips

1. Division can be done in April. When the weather gradually warms, dig up the old plants, shake off some of the soil, and cut them into several blocks (clumps) with a sharp knife or a sharp spade, with 4-7 buds per clump, and plant them separately.

2. Cuttage propagation can be done in spring and summer. Cut young shoots 6-7 cm long, remove the leaves at the base, and keep only the leaves at the top 2 nodes. Insert 1/3-1/2 of the cuttings into wet sand, either in pots or in open-ground beds. After inserting, cover with plastic film, spray water once every day at noon, keep the temperature at 20-25°C, and roots will form in about 30 days.

3. Sow seeds in pots in March-April. Put the culture soil into a suitable pot, water thoroughly, and sow broadcast after the water seeps in. Because its seeds are tiny and light, you can mix in some fine sand and mix evenly before sowing. After sowing, sieve a layer of fine soil over the top and cover the pot mouth.

Purple loosestrife planting density

Planting density is very important for both the normal growth of the plants themselves and the requirements for landscape beauty. If the planting density is too high, it not only wastes seedlings, but also, because the plants' nutrient area is too small, the recovery time after planting is prolonged, growth is poor, and at the same time ventilation and light are seriously affected, which can lead to pests and diseases, causing the leaves to turn yellow or even die, with a very big impact on the overall landscaping. If the planting density is too low, the plants will also be at a disadvantage in competition, and weeds can easily multiply, causing great difficulties for later maintenance and management. As an emergent aquatic plant, purple loosestrife is generally planted at a density of 16-25 plants per sq m.

[Common question] How to plant purple loosestrife? Purple loosestrife planting methods

[Expert answer]

Introduction:

A perennial herb of the Lythraceae family and Lythrum genus, with a stout rhizome lying horizontally underground; the stem is upright, much branched, the whole plant is green, slightly covered with coarse hairs or densely covered with down, and the branches usually have 4 angles. Leaves are opposite or in whorls of three, lanceolate or broadly lanceolate, with an obtuse or shortly pointed tip, a rounded or heart-shaped base, sometimes slightly clasping the stem, entire, and sessile. The flowers form small cymes, clustered, and because the pedicels and main peduncles are extremely short, the whole flowering branch looks like a large spike; bracts are broadly lanceolate to triangular-ovate, triangular; appendages are needle-like, upright, red-purple or light purple, oblanceolate-oblong, with a wedge-shaped base, borne on the upper part of the calyx tube, with a short claw, slightly wrinkled; extending beyond the calyx tube; ovary 2-locular, style of varying length. The capsule is flat and round.

Planting techniques:

1. Propagation and sowing

Seed propagation: sow in spring in March-April. Before sowing, mix the seeds evenly with fine soil, then sow broadcast in the bed, cover with 25px of soil, and finally cover with grass and water. Seedlings emerge 10-15 days after sowing; uncover the grass immediately. Transplant when the seedlings are about 250px tall. Open holes at a row spacing of 750px500px, and plant 3 plants per hole.

Cuttage propagation: mainly division propagation, but sowing or cuttage propagation can also be used. For cuttage, select robust branches in spring, cut them to about 300px long, remove the leaves, insert them diagonally into the soil to a depth of 1/2 of the cutting, press firmly, water to keep moist, and transplant after rooting and leaf growth. Division propagation: in spring from April to May, dig up the root clumps, cut them into clumps of several buds, and plant them in wet ground with sufficient base fertilizer.

2. Key cultivation points

(1) It has low requirements for soil, is cold-resistant, and likes light and moisture. Fertile soil is best for cultivation.

(2) It can be propagated by sowing, cuttage, division, and other methods. Sowing must be done in wet ground; cuttage is done in June-July. Cut off new branches, insert them into muddy water, and they can root in one month; division is done in spring. Dig out the old plants, cut them into several parts, and plant them separately.

(3) It can be planted once and harvested for many years.

3. Field management

After planting and before the rows close, cultivate and weed 3-4 times each year. Apply nitrogen fertilizer or compound fertilizer once each in spring and summer, and apply compost or barnyard manure once after autumn. Keeping the soil moist at all times is the most critical measure for growing purple loosestrife well.
