A Detailed Guide to Flower Fertilization Methods: Teaching You How to Fertilize Reasonably

As people's living conditions improve, almost every household grows some flowers and plants at home. If you want these flowers to bloom beautifully, you should understand their habits and master their fertilization methods. So how should flowers be fertilized? Today, the editor will share with you what the commonly mentioned "three looks" of flower fertilization refer to.

First, look at the season. In winter, temperatures are low and plant growth is slow. Most flowers are in a state of suspended growth, so generally no fertilizer is applied. Spring and autumn are the peak growth periods for flowers, when roots, stems, and leaves grow, flower buds differentiate, and young fruits swell, all of which require more fertilizer, so appropriate additional fertilizing should be applied more. In summer, temperatures are high, water evaporates quickly, and it is also a period of vigorous growth for flower plants, so the concentration of additional fertilizer should be low and the frequency can be higher. At the seedling stage, more nitrogen fertilizer can be applied to promote rapid, robust growth of seedlings. At the bud stage, more phosphorus fertilizer can be applied to promote large flowers and strong seeds. At the early fruit-setting stage, fertilization should be appropriately controlled to help fruit set.

Second, look at the variety. Different varieties of flowers have different fertilizer requirements, so different fertilizers should be applied. For example, osmanthus and camellia like pig manure and avoid human feces and urine. Southern flowers such as rhododendron, camellia, and gardenia avoid alkaline fertilizers. Flowers that need heavy pruning every year require a larger proportion of phosphorus and potassium fertilizer to promote the sprouting of new shoots. For foliage-oriented flowers, more nitrogen fertilizer can be applied. For flowers with large blooms, such as dahlia and chrysanthemum, an appropriate amount of complete fertilizer should be applied during the flowering period so that all flowers can open, with beautiful shapes and vivid colors. For fruit-oriented flowers, water should be appropriately controlled during the flowering period, and sufficient complete fertilizer should be applied during the fruit-swelling stage to achieve the expected effect. For bulbous flowers, more potassium fertilizer should be applied to help the bulbs become plump. For fragrant flowers, when they enter the flowering period, more phosphorus and potassium fertilizer can promote a stronger floral fragrance.

Third, look at the growth condition. Especially for potted flowers, fertilization should be based on growth condition to determine the amount. Adhere to the principle of "four more, four less, four no": apply more when yellow and thin, apply more before sprouting, apply more at the bud stage, apply more after flowering; apply less when thriving, apply less at sprouting, apply less when flowering, apply less in the rainy season; do not apply when leggy, do not apply when newly planted, do not apply in the height of summer, do not apply during dormancy. At the same time, attention should be paid to the "four taboos": first, avoid concentrated fertilizer; second, avoid raw fertilizer (organic fertilizer must be fully decomposed before use); third, avoid hot fertilizer (in summer at noon, soil temperature is high, and fertilizing easily damages roots); fourth, avoid sitting fertilizer, that is, when planting flowers, do not place the roots directly on the base fertilizer at the bottom of the pot, but add a layer of soil on top of the fertilizer, and then plant the flowers into the pot.
