Is gardenias easy to feed?
The white and fragrant gardenia is popular among home gardeners. This woody plant not only has high ornamental value, but its fresh aroma can purify indoor air. However, many flower lovers are often confused about whether gardenia is suitable for family cultivation. In fact, as long as they master their growth laws, they can completely build gardenia gardens at home through scientific maintenance. Analysis of growth characteristics of gardenia, environmental adaptability, gardenia's light demand varies seasonally: full sunshine can be accepted in spring and autumn, and 40%-50% of shade needs to be shaded in summer. The temperature adaptation range is between 15-28℃, and it is necessary to stay above 5℃ for winter. The air humidity should be maintained at 60%-70%, which can be adjusted by laying pebbles on trays and injecting water. Special requirements for soil As a typical acidophilic plant, gardenia needs an acidic substrate with a pH of 5.0-6.5. Recommended formula: 50% peat soil +30% pine needle soil +20% perlite, supplemented with 0.2% ferrous sulfate solution every quarter. Pay special attention to areas with alkaline water quality in the north, which need to be irrigated with rainwater or tap water that has been left to rest for 3 days. The key points of home maintenance Scientific water management adopts the principle of "seeing dry, seeing wet": watering thoroughly in 5-7 days in spring and autumn, and watering once in the morning and evening in summer with foliar spray. Control water for 10-15 days per time in winter. Determine the humidity by bamboo stick testing: insert 2/3 of the soil in the basin, and water is needed when it is pulled out that does not touch the soil. Nutrient supply strategy Use N-P-K=15-30-15 flowering fertilizer for long-term growth from March to June, 7-10 days per time; use balanced compound fertilizer from July to September; stop fertilization in winter. Combined with the monthly application of decomposed rice washing water, flower bud differentiation can be promoted and flower diameter can be increased by 30%. Solutions to common problems need to be differentiated according to the problem of yellow leaves: yellowing of old leaves is a natural metabolism, and the soil pH value needs to be tested for yellowing of new leaves. Most of the flower bud shedding is due to insufficient temperature difference between day and night, which can be improved by opening windows at night to create a temperature difference of 8-10℃. Regular wiping of leaves with tobacco water can effectively prevent red spiders.
By systematically mastering the ecological habits and maintenance skills of gardenia, even novice gardeners can make the plants bloom 3-4 times a year. It is recommended to place the potted plants on the east-facing balcony to not only ensure morning light, but also avoid burns caused by strong noon light. Follow these maintenance principles and you will be able to harvest fragrance throughout the room.
