Gardenia cultivation
One, soil: gardenia is acidic soil indicator plant, so the soil of slightly acidic environment, is the key to decide gardenia growth good or bad. Cultivates the soil to apply the slightly acid sandy loam red soil 7 into, the humus 3 into mixes and becomes. Will soil pH value control between 4.0-6.5 is suitable.
Two, temperature: the best growth temperature of gardenia is 16℃-18℃. The temperature is too low and the direct sunlight is extremely unfavorable to its growth, so it is suitable to put the gardenia in the summer to ventilate well, the air humidity is big and translucent under the maintenance of the open forest or the shade shed. Winter put in see sunlight, temperature and not below 0 ℃ environment, let it dormant, temperature too high will affect the next year flowering.
Three, water: gardenia like air moist, growth period to moderate increase watering. Usually potting soil white can watering, one time watering thoroughly. Summer dry heat, every day shall to leaf surface spray 2 times -3 times, to increase air humidity, help plant cooling. But after the flower buds, watering should not be too much, so as not to cause bud drop. Winter watering to dry is good, to prevent water rot roots.
four, fertilizer: gardenia is like fertilizer plant, in order to satisfy its growth period to the demand of fertilizer, but also can keep the soil slightly acidic environment, can be mixed into the fertilizer solution beforehand ferrous sulfate fermentation. Into the growth season in April, can half a month after fertilizer (fertilizer is best to more water, in order to prevent burning flowers). This not only can satisfy the gardenia to the fertilizer demand, but also can keep the soil environment in relative balance slightly acid environment, prevent the occurrence of yellowing disease, at the same time but also avoids the sudden make up ferrous sulfate, the local over-acid to the gardenia's harm.
five, propagation: although propagation of gardenia has many kinds of methods, but the most simple and quick is floating water plug method, first find foam board a piece, and to the upward hole, will gardenia that year half-mature branch cut, insert the foam board in the hole, and then put the foam board into the bucket full of water, will put the bucket on the both can let the floating board spikes shading, but also let the sunlight irradiation water bucket environment, will control the temperature of the water in the 18℃- Between 25 ℃, gardenia a week that can grow more than 3 centimeters of root. This method cuttings gardenia, survival rate is 100%.
