Detailed Explanation of Dwarfing Techniques and Care Methods for Nursery Stock and Flowers

Pruning and shaping. When the flowering shrubs reach a certain height, pinch out the growing tips in time, widen the branching angle, and shape by twisting and bending branches to suppress apical dominance, shorten the vegetative growth cycle, and promote flowering and fruiting.

Regulation treatment. After the flower seedlings are transplanted into pots, spray Chuhuawang No. 3 during the growth period to assimilate and induce transmembrane signal transduction in plant cells, forcing the vigorous nutrients at the shoot tips to flow back in large amounts, so that the inertial advantage of shoot flushing is rapidly weakened to a capped state.

Select dwarf varieties and grow dwarf, sturdy seedlings. Use nutrient pot seedling cultivation to limit the deep development of the main root, promote well-developed fibrous roots, and suppress the growth of stems and leaves above ground.

Potting and cutting the radicle. When flower seedlings are planted in pots, cut the radicle short, spread the lateral roots in all directions during transplanting, and fill soil in layers. For example, when potting chrysanthemums, at first add only two-thirds of the culture soil, and as the plant grows, gradually add soil to bury several old leaves at the base, prompting the base stem to thicken and the plant to become dwarf and sturdy.

Control fertilizer and restrict water. By repotting, continuously renew the culture soil, generally repotting once every 1 year to 2 years; according to plant growth, move from a small pot to a large pot and replace old soil with new soil. In conjunction with repotting, carry out root pruning and branch training, improve and recommend the tree form structure, and promote dwarf sturdiness. Control nitrogen fertilizer, increase the application of phosphorus and potassium fertilizer, and strictly avoid waterlogging and excessive humidity to prevent leggy growth and root rot leading to seedling death.
