What are the flower propagation methods? A detailed explanation of division propagation techniques

Division propagation is the main propagation method for perennial flowers. It mainly uses the characteristic that shoots are produced at the base or roots of the plant, and artificially separates or cuts part of the plant's vegetative organs from the mother plant, then replants and cultivates them separately, thereby forming new plants that live independently.

Division propagation can maintain the plant's genetic traits, is also very simple to carry out, helps the plants survive, and produces seedlings quickly. It mainly includes division of clumps and division of bulbs. Below, the editor will explain it to you in detail.

1. Division of clumps

Division of clumps is mostly used for flowers with strong clumping growth. It is a propagation method in which a rooted clump of the plant is divided into multiple plants. For example, perennial herbaceous flowers such as chrysanthemum, peace lily, orchid, Chinese peony, and Hosta, as well as woody flowers such as wintersweet and tree peony, can all be propagated by division of clumps.

According to the source of the sprouting shoots, division of clumps can be divided into three types. The first is division of short stolons, which is suitable for plants such as those in the Liliaceae, Musaceae, and Arecaceae families. The second is division of root suckers; root suckers are shoots sprouting from roots, and plants such as pineapple and redwood are suitable for propagation by this method. The third is division of rhizomes; herbaceous plants such as New York aster, hydrangea, and Hosta, and woody plants such as cherry, oleander, and kerria can be propagated by this method.

In addition, there are also the bulbil division method and the runner division method. Lilium lancifolium and lilies can use the bulbil division method. Saxifraga stolonifera, spider plant, and buffalo grass can use the runner division method.

2. Bulb division

Bulb division is a method of propagation using underground modified organs or specialized organs with a storage function. There are many types of underground modified organs. According to differences in their source of variation and characteristics, they can be divided into bulbs, corms, tubers, and rhizomes. Therefore, gardening enthusiasts should note that different plants use different propagation methods.

1. Bulbs

A bulb is composed of small scales. The nutrient meristem at the center of the bulb develops in the axils of the scales, producing small bulbs. Bulbs, small bulbs, and scales can all be used as propagation material. Narcissus, tulips, and bulbous irises are often propagated using grown small bulbs.

2. Corms

A corm is an underground modified stem formed by the swollen base of the stem axis. It is spherical and is the plant's nutrient storage organ. After the old corm sprouts, a new corm forms at the base, and daughter corms then form beside the new corm. The new corm, daughter corms, and old corm can all be planted separately as propagules.

3. Tubers

A tuber is a modification of an underground stem formed by swelling at the subapical part of a stolon. The tuber is a storage and propagation organ. Tuber propagation can be done using the whole tuber or by cutting it with buds. Jerusalem artichoke and caladium can both be propagated by this method.

4. Rhizomes

A rhizome is a specialized stem structure. Rhizome propagation is usually carried out in the early part of the growing season or at the end of the plant's growth period. When cutting rhizome segments, each segment must have at least one lateral bud or bud eye, which in practice is equivalent to stem cutting propagation.

A brief discussion of division propagation techniques for home flowers

Flower types include herbaceous flowers (annual herbaceous flowers, biennial herbaceous flowers) and woody flowers (trees, shrubs, vines). Because the types differ, their propagation methods also differ somewhat. The common main ones are the division method (used for flowers with strong clumping growth and strong suckering ability) and the bulb division method (used for bulbous flowers). Next, the editor will briefly talk about division propagation techniques for home flowers, hoping it can be of some help to everyone.

1. Division method

1. Meaning of the division method

The division method is to cut off the sprouts or runners from the root crown of the mother plant and separate out a new plant. It has the advantages of a high survival rate and keeping the flower's characteristics unchanged.

2. Flowers suitable for division

Aspidistra, bamboo palm, calla lily, iris, daylily, clivia, canna, asparagus fern, rhapis palm, Echeveria, and corm- and bulb-type flowers, etc.

3. Best time for division

Spring is best, autumn is also acceptable, and of course some flowers are not limited by season.

4. Preparation before division

A sterilized sharp knife, new pots, culture soil, sulfur powder, mosquito coil ash.

5. Operating steps

① Rhizomatous flowers such as orchid, asparagus fern, Hosta, spider plant, calla lily, etc.

First remove the flower from the original pot, then use a small knife to cut vertically at the rhizome, cutting it into 3-4 pieces. Each piece must have stems, leaves, and roots. Apply sulfur powder or mosquito coil ash to the cut surfaces for antisepsis, and plant them separately into the prepared new pots.

② Corm- and bulb-type flowers such as tulip, gladiolus, tuberose, lily, etc.

After the flowers bloom, dig out the bulbs in summer, break off the small bulbs and dry them, store them, and plant them at the appropriate time.

③ Large flowers such as rhapis palm, ginkgo, etc.

Cut off part of the roots with bud eyes from the mother plant, apply plant ash or sulfur powder to the cut surfaces for antisepsis, and plant them into the prepared pots.

6. Management after division

Water thoroughly, place in a cool and ventilated place, and move into the sun after several days.

2. Bulb division method

1. Advantages of the bulb division method: it flowers earlier than propagation by sowing, and the method is simple.

2. Naturally separate the newly produced tubers, corms, rhizomes, bulbs, tuberous roots, etc., and plant them separately, and they will grow into independent new plants.

3. Time for bulb division: mostly during the dormant period or before harvesting and planting the bulbs.

Division propagation techniques for flowers

1. Definition

Division propagation is a propagation method in which the small young plant bodies produced by the plant body or part of the plant's vegetative organs are artificially separated or cut from the mother plant and planted separately to form new plants that live independently.

2. Methods

According to differences in flower types, division propagation can be divided into the division of clumps method and the bulb division method. The division of clumps method is mostly used for shrubs with strong clumping growth and perennial herbaceous flowers with strong suckering ability, while the bulb division method is mainly used for bulbous flowers.

(1) Division of clumps method. This method is a simple way to propagate flowers and trees. It has a high survival rate and produces seedlings quickly, but the number of seedlings produced is small. Ferns, asparagus fern, snake plant, rhapis palm, pepperomia, begonia, spider plant, clivia, etc. are commonly propagated by this method.

① Time for division: for deciduous flower and tree types, division propagation should be carried out during the dormant period.

In the south, it can be done after leaf fall in autumn. This is because winters in the south are not severely cold and the air is relatively humid. Some flowers and trees can still grow some new roots before winter, and the branch tips will not dry out in winter. It can also reduce the intense pressure of labor in spring.

In the north, it should be done in early spring after the soil thaws and before the plants sprout. This is because winters in the north are severely cold and the air is dry. Apart from potted flowers and trees overwintering indoors, autumn-divided seedlings mostly have a low survival rate, so it should be scheduled before sprouting in early spring.

Evergreen flowers and trees do not have an obvious dormant period, but during winter greenhouse maintenance most grow slowly or are in a semi-dormant state. If divided in autumn, not only are new roots not easily produced, but a large number of divided seedlings will also increase the pressure on the greenhouse. Therefore, it should be done in spring, moving them out of the greenhouse while also removing them from pots and dividing them.

② Division methods: there are many methods.

Propagation by tiller seedlings: cut off the tiller seedlings produced at the root crown or from underground stems and plant them, so that they form independent plants. Such as Cymbidium goeringii, daylily, Hosta, goldenrod, etc. In addition, hollyhock and perennial phlox can produce "root suckers" from the roots. Some lawn and groundcover plants in the grass family can also use this method. In horticulture, the method of wounding the roots is also used to promote the production of root suckers in order to increase the propagation coefficient.

Propagation by suckers: suckers are shortened, thickened, rosette-like short branches naturally produced at the root crown or in the leaf axils of aboveground stems of certain plants. The lower part of the sucker can naturally root, so it can be separated from the mother plant and planted separately. For example, among succulent plants, aloe, sedum, etc. often bear suckers at the root crown; pineapple can also produce suckers in the leaf axils of aboveground stems, and can also be propagated by this method. In horticulture, the method of injuring their roots is often used to stimulate these plants to produce suckers.

Propagation using bulbils and aerial tubers: bulbils are special forms of buds possessed by certain plants. Some are borne in leaf axils, such as Lilium lancifolium; others are borne in inflorescences, such as ornamental alliums. Aerial tubers are bulb-like or tuber-like, such as in Dioscorea species.

After bulbils and aerial tubers separate from the mother plant, they can naturally fall to the ground and root. In horticulture, this habit is often used for propagation.

Propagation using runners or stolons: a runner is a stem with relatively long internodes produced from a leaf cluster. Leaves, flowers, and adventitious roots are borne at the nodes, and small young plants can also be produced. Separate the small plants and plant them separately to form new plants. Flowers propagated by runners include Saxifraga stolonifera, spider plant, etc.

Stolons are similar to runners, but the internodes are slightly shorter. They creep horizontally along the ground and produce adventitious roots and buds at the nodes. They are mostly seen in lawn plants of the grass family, such as bermuda grass and buffalo grass.

(2) Bulb division method. Most bulbous flowers have a very strong ability to regenerate from their underground parts, and can produce some new small bulbs every year. Propagating with them flowers earlier than propagation by sowing, and the method is simple. Naturally separate the newly produced bulbs (tulip, lily), corms (gladiolus, freesia), tubers (cyclamen, calla lily), rhizomes (canna, lotus), tuberous roots (dahlia), etc., and plant them separately, and they will grow into new independent plants. The time for bulb division varies with different species, and is generally carried out during the plant's dormant period in spring and autumn.
