What is the best fertilizer for gardenias
This article brings you the knowledge of the best fertilizer for gardenias and the timing and methods of fertilizing them. Next, the editor will introduce you to this information.
Gardenias are difficult to grow well in northern regions and require careful attention to become more beautiful. A common problem that people often encounter is what type of fertilizer is better for gardenias? Generally, a base fertilizer should be mixed in during planting, nitrogen fertilizer should be supplemented during the growth period, phosphorus and potassium fertilizers should be emphasized during the budding stage, and compound fertilizers should be applied after flowering. Let's analyze this in detail.
Ⅰ. Selection of Base Fertilizer
Gardenias naturally like fertilizer, and a lack of nutrients can slow down their growth, making it uncertain whether they will bloom. Therefore, when planting or repotting, organic fertilizers, soybean cake fertilizers, or decomposed animal manure can be placed at the bottom of the pot to lay a solid foundation for the growth of gardenias. Using chemical fertilizers as a base fertilizer can potentially burn the roots, which is not recommended.
Ⅱ. Growth Period
Gardenias sprout one after another and enter the growth stage. At this time, a liquid nitrogen fertilizer or a compound fertilizer with a higher nitrogen content can be applied every 10 days, which can quickly sprout new growth. Additionally, to prevent the soil from becoming too alkaline, an appropriate amount of ferrous sulfate solution can also be supplemented.
Ⅲ. Bud Formation Stage
When gardenias are about to form flower buds, fertilizers with a focus on phosphorus and potassium elements should be used. This can promote the speed of flower bud differentiation and make the flowers more beautiful. Apply 2-3 times a month, and stop fertilizing when the flower buds show white and are about to open to prevent bud drop.
Ⅳ. After Flowering
After the gardenia has finished blooming for the last time, a compound fertilizer containing multiple elements can be applied, 1-2 times, to replenish the nutrients consumed during the flowering period. Fertilizing should be stopped when the temperature drops below 10°C in winter. We place it in a location with ample scattered light until the following spring when the fertilization process can start again.
Ⅴ. Precautions
Sandy the soil the day before fertilizing to facilitate the absorption of nutrients by the plant and achieve the best fertilizer effect. Water the plant the day after fertilizing to prevent the accumulation of fertilizer in the soil, which can cause fertilizer damage. Fertilizing should be cautious, especially during these times: fertilize after the spring starts, do not fertilize after the autumnal equinox, fertilize when flower buds appear, do not fertilize when they crack open. Fertilize on sunny days before rain, not after. Fertilize when the potting soil is dry, not when it's wet. Apply thin fertilizers frequently, avoid thick fertilizers. Fertilize before and after flowering, not during flowering. Apply fertilizers in the morning and evening, not at noon. Fertilize more for strong seedlings, not for weak ones.
