How to grow gardenias well
The editor answers the question of how to grow gardenias well, sharing experiences on this aspect. The introduction of methods for growing gardenias well, the editor of this site will introduce the following.
1. Gardenias prefer acidic soil and require iron and magnesium. Good acidic soil can promote the absorption of iron by gardenias, promote the formation of chlorophyll, and ensure that the leaves remain lush and green. In addition to acidic soil, if the soil is rich in humus, fertile, loose, and well-drained, and pine sawdust is decomposed and mixed into the soil, it will be more suitable for the growth of gardenias.
2. Gardenias enjoy shade and are averse to direct sunlight. It is important to avoid strong sunlight and exposure to intense sunlight when cultivating gardenias. However, this does not mean that gardenias do not need sunlight at all. While creating a shaded environment, it is necessary to maintain about 60% of full-day sunlight. Especially in the early morning and evening, gardenias should be exposed to more sunlight to meet their growth needs.
3. Gardenias enjoy humidity and are afraid of dryness. If the air humidity is lower than 70%, it will directly affect the differentiation of flower buds and the growth of flower buds, but excessive humidity can cause root rot and branch withering, and yellowing and falling of leaves. In addition to regular watering, the leaves and surrounding ground should be frequently sprayed with water to appropriately increase air humidity. Gardenias are especially afraid of dry hot winds, and as mentioned earlier, gardenias prefer shade, so they should be protected from the damage of dry hot winds.
4. Gardenias require frequent application of thin fertilizer and dislike raw fertilizer. For fertilizing gardenias, we need to use thoroughly decomposed fertilizer, applying thin fertilizer frequently and avoiding raw and concentrated fertilizers. It is suitable to apply decomposed soybean cake, sesame paste residue, peanut bran, and other fertilizers, which become acidic after fermentation and can make the leaves green and the flowers abundant, but thin fertilizer must be applied frequently.
5. Gardenias enjoy warmth and are afraid of cold. Gardenias are susceptible to cold, and it is necessary to maintain a temperature of 8-10°C during the winter, with an optimal growth temperature of 18-22°C.
6. Gardenias should be pruned in time and well-ventilated. Timely pruning can reduce unnecessary nutrient consumption by excess branches and leaves, affecting the growth of the entire plant. Gardenias have a strong germination ability, which can easily lead to a messy tree shape and scattered nutrients. During shaping, three main branches should be selected according to the tree shape, and other branches that sprout from the roots should be pruned at any time.
