What are the methods for dwarfing seedlings and flowers? A detailed explanation in one article

Seedlings and flowers are often seen in daily life and have a very good decorative effect. Today, the editor will share with everyone.

1. Strengthen pruning and shaping. To dwarf seedlings and flowers, pay attention to pinching the tips in time once the flowers and trees grow to a certain height, adopt methods such as opening the branching angle and twisting and bending branches for shaping, inhibit apical dominance, shorten the vegetative growth cycle, and promote flowering and fruiting.

2. Chemical regulation. Apply chemically synthesized growth inhibitors to promote dwarfing. When transplanting flower seedlings into pots, mix a certain amount of paclobutrazol into the potting soil, and during the growing period spray or water in 0.15% to 0.25% paclobutrazol, or use growth inhibitors such as chlormequat and B9, which can inhibit cell elongation, promote cell division and thickening growth, and achieve the goals of thick leaves and strong branches, a dwarfed and compact crown, and abundant flowers and bright fruit, improving ornamental value.

3. Select dwarf-type varieties. The characteristics of dwarf varieties are many buds and strong branching ability, low branching position, large branching angle, short internodes, and a compact plant shape. The main root is not obvious, the lateral roots are well developed, and there are many fibrous roots.

4. Grow short and sturdy seedlings. Use nutrient pot seedling cultivation to limit the deep development of the main root, promote well-developed fibrous roots, and correspondingly inhibit the growth of aboveground stems and leaves.

5. Prepare good potting soil. Potting soil is the foundation of potted flowers. It is required to be rich in organic matter, have a good granular structure, be fertile and loose, and have comprehensive nutrition. It is made by mixing and composting leaf mold, garden soil, pond mud, peat soil, river sand, organic fertilizer, phosphate fertilizer, bone meal, plant ash, and so on. The pH value is slightly acidic to slightly alkaline, and the specific adjustment should be made according to the adaptability of different flower varieties to acidity and alkalinity.

6. Break the radicle before potting. When planting flower seedlings in pots, cut the radicle (main root) short, spread the lateral roots around when transplanting, and fill soil in layers. For example, when potting chrysanthemums, at first add only two-thirds of the potting soil, and as the plant grows, gradually add soil, burying a few old leaves at the base, prompting the basal stem to thicken, and growing thick leaves near the pot rim, making the plant short and sturdy.

7. Repotting, fertilizer control, and water control. For potted flowers, nutrient soil base fertilizer is the main part. Therefore, through repotting, the potting soil should be continuously renewed, generally repotting once every 1 to 2 years. According to the growth of the plant, move from a small pot to a large pot, and replace old soil with new soil. Combined with repotting, carry out root pruning and branch trimming, improve the recommended tree shape structure, and promote short and sturdy growth. Control nitrogen fertilizer, increase the application of phosphorus and potassium fertilizers, and by all means avoid excessive waterlogging and humidity, so as to prevent leggy growth and root rot and dead seedlings. Especially during the peak growth period, control water and fertilizer, ensure the potting soil is dry and wet alternately, save water and reduce fertilizer, promote steady growth, and achieve more branching, more flowers, dense nodes and short branches, and dwarfed plants.

That is all for sharing with everyone. I believe everyone has gained a certain understanding. I hope this article is helpful to everyone.
