Gardenia, Chinese Rose, Azalea...Die Every Time You Try? Learn This Trick
Gardenia, Chinese rose, and azalea are the three major ornamental flowers, yet countless gardening enthusiasts fail repeatedly. Despite careful attention, they often encounter issues like flower buds falling and yellowing leaves. This article will delve into the pain points of caring for these three plants and guide you step by step on creating healthy, continuously flowering plants.
Complete Guide to Caring for Gardenia
Solution to Unopened Flower Buds
① Light Control: Ensure 4-6 hours of diffused light daily, avoiding direct sunlight at noon in summer. ② Precise Fertilization: Apply monopotassium phosphate solution (1:1000) weekly during the bud formation stage, with the addition of decomposed cake fertilizer for better results.
System for Preventing Yellow Leaves
Establish a soil pH monitoring mechanism, testing with pH paper monthly. If the value exceeds 6.5, adjust with ferrous sulfate (0.2% concentration). Soil improvement suggestion: Mix decomposed leaf soil, river sand, and pine needle soil in a ratio of 5:3:2.

Preventive spraying plan: Use garlic juice (1:50) + rice vinegar (1:200) and spray the back of the leaves weekly during the early spring germination stage. Treatment during the disease stage: First, physically remove the diseased leaves, then spray a mixture of baking soda (5g/L) + dishwashing liquid (2 drops/L) for 3 consecutive days.
Technique for Continuous Flowering
After flowering, follow the "333" principle: retain 3 main branches, with 3 buds on each branch. Fertilization strategy: Immediately replenish a balanced nitrogen-phosphorus-potassium fertilizer after flowering, and switch to a high-phosphorus fertilizer 10 days later to promote a second flowering.

Humidity Control Plan
Create a micro-ecosystem: Place a water-holding tray (with a layer of pebbles) at the bottom of the pot, and mist the leaves in the morning and evening (avoiding the flowers). During the winter heating period, use an ultrasonic humidifier to maintain 50%-60% air humidity.
Soil Improvement Plan
Upgrade the substrate formula: Mix peat soil, pine bark, and perlite in a ratio of 4:4:2, and supplement with sulfur powder (10g/pot) every quarter. Set a 3cm thick layer of ceramic stones at the bottom of the pot to prevent waterlogging and root rot.
With a systematic care plan, the three ornamental plants can achieve continuous flowering. The key is to master: ① Light cycle control ② Precise nutrient supply ③ Environmental parameter monitoring. It is recommended to establish a care log, recording each application of fertilizer, pruning, and data on pest and disease control to gradually form a personalized care plan.
