Matters needing attention in gardenia cultivation are as follows.
1, soil requirements. To cultivate potted gardenia, loose, fertile and well-drained soil should be used as the cultivation substrate. The ph value of soil should be acidic, generally between 4.0 and 6.5. Alkaline soil is not suitable for planting gardenia, otherwise gardenia can't absorb iron and will turn yellow and wither.
2, suitable for lighting. Gardenia needs sunshine to grow and bloom, but it is not resistant to exposure, so it is best to put it in a place with sufficient scattered light for maintenance when potted, which is most conducive to the growth of Gardenia. Shading measures should be taken for gardenia in summer. If the light is too strong, the leaves of gardenia will be burned.
3. Reasonable water and fertilizer. To cultivate potted gardenia, water and fertilizer should be applied reasonably, the soil should be kept slightly wet during the growth period, and water should be sprayed around frequently to increase the air humidity. Note that the soil can't accumulate water, and the fertilizer can be applied once every half month. Pay attention to the principle of thin fertilizer and diligent application.
4. Other precautions. Attention should be paid to pruning during the cultivation of potted gardenia. After it blooms, it is necessary to cut off the residual flowers and dead branches, as well as some dense horizontal branches and twigs, so that the interior of gardenia will be more ventilated and transparent, and its new branches can also be picked and germinated properly, which is beneficial to the beauty of its plant type.
