How to grow gardenias to make them bloom
The following is a detailed introduction for netizens on how to grow gardenias to make them bloom and the correct maintenance methods for green plants and flower planting, which will surely be helpful to you. Let's learn about it together!
Gardenias are more suitable for growing in southern regions. If you are in the north and want to make them bloom, it requires a bit more effort. During the daily maintenance process, you need to manage the following six aspects. The following is a detailed introduction on how to maintain gardenias to make them bloom.
1. Suitable Soil
Gardenias prefer slightly acidic soil and are very sensitive to pH levels. They cannot survive in alkaline soil, let alone bloom.
The most suitable pH environment is between 5-6. Avoid using coal slag as a planting material. It is recommended to purchase soil for growing orchids for the best results.
2. Scientific Watering
Gardenias prefer moist soil and climate. Water the soil when it turns white and water thoroughly. In summer, when temperatures are high, spray the leaves 2-3 times a day to increase humidity. When watering plants with tap water in northern regions, fill the container in advance and let it sit for two days. Add 1 gram of ferrous sulfate and 0.5 grams of citric acid to the water every 3-5 days.
3. Reasonable Fertilization
Gardenias enjoy fertilizer. Before planting the plant, you can mix 3% of decomposed cake fertilizer into the soil as a base fertilizer. During the growing season, water with a mixture of cake fertilizer and alum fertilizer once a week, or 0.1% humic acid all-purpose nutrient solution.
4. Enhanced Lighting
Gardenias need ample sunlight to bloom. If there is not enough sunlight, the plant will only grow leaves and not bloom. Except for shading during July-August and the dormant winter period, the plant can be exposed to full sunlight at other times of the year.
5. Timely Potting
If the pot is too small and the plant's growth is restricted, it will also affect blooming. When the plant's canopy reaches 2-3 times the diameter of the pot opening, it is time to repot. Repotting is usually done during the plant's growing period. The new pot should be 5 centimeters larger than the old one. When the pot opening reaches 28 centimeters, no further repotting is needed, only change the soil.
6. Appropriate Pruning
When the main stem reaches 20 centimeters, pinch the top, leaving 3-4 branches. When these branches grow 2 pairs of leaves, pinch the top again to promote more branching. After that, there is no need to pinch the top, allowing the plant to grow freely.
The above is the detailed explanation on how to grow gardenias to make them bloom and the correct maintenance methods. I hope it brings a little help to your life!
