1. Reason: for Rhododendron, the more water and fat, the better. When it is raised, if there is too much fertilizer and water, it will only grow leaves and not bloom, which is often said to be over nutrition, so that new branches will grow all the time, but will not bloom.
2. Solution: at this time, artificial methods can be used to suppress the phenomenon of over nutrition, so as to promote it to blossom. Specifically, before flowering, we can not apply nitrogen fertilizer to it, just add a certain amount of P and K fertilizer, so as to prevent the nutrition from being too sufficient, and let its buds differentiate. Make it bloom more. After that, we need to cut off the long branches, leaving only 4 to 5 new branches.
1. Reason: when it grows, if the phosphate fertilizer is not enough, it will make the flower bud hidden in the leaf bud unable to grow again, so when it grows leaves next year, it will not see the flower bud, so it will be mistakenly considered that the flower bud becomes a leaf.
2. Solution: when its flower bud is just growing, it will first enter into the period of flower bud differentiation. At this time, it needs to apply enough phosphate fertilizer to it, so that it will be conducive to the early formation of the flower bud. Once the flower bud is formed, it will immediately blossom.
1. Reason: when it lacks sunshine, it can't produce enough nutrients to promote the growth of flower buds, so it can't bloom.
2. Solution: at this time, it is necessary to add light to it, so that the plant can play the role of light, so as to bring it enough nutrition, so that the flower buds can form as soon as possible.
