If the flower bud is to open smoothly, there must be enough fertilizer and water during the flowering period.

Many varieties of rose have large flowering and many flowers, so they need a lot of nutrient supply, and close to the usual watering and sun exposure is obviously unable to meet the nutrient needs of plants. At this time, it is necessary to fertilize the rose properly, but fertilization is also fastidious, and flower friends should not fertilize it on a single-minded basis. It is necessary to apply fertilizer correctly in order to get good results.

We roughly divide the fertilization time of rose into pre-flowering, mid-flowering and post-flowering. So first of all, let's briefly understand, when is the so-called pre-flowering? This is very simple, that is, when you find it popping out of a bud, you should know to replenish it in time.

Fertilization before flowering can promote the growth of buds, make flowers bigger and more beautiful, and most importantly, at least ensure the necessary nutrients for flowering, you know, many buds can not open smoothly because of lack of nutrients.

As for whether to apply fertilizer during the flowering period? This should be determined according to the size of the plant and the number of buds. If the plant is small, in fact, if the corresponding fertilization has been done before flowering, the nutrients of the plant can be adequately supplied, and there is no need to apply fertilizer at this time.

If blind branches are found, it means that the plant is malnourished. Or carefully observe the leaves, if found after flowering that the leaves are not so green and watery, it shows that the nutrients are insufficient. If the plant has grown luxuriantly and has a large number of flowers, it is also necessary to apply fertilizer.

Fertilization can be applied during the flowering period, but we must pay attention to the problem of balance and avoid making the plant full and hungry. At this time, fertilization advice is not to supplement nitrogen fertilizer, but to add a little more phosphorus and potassium fertilizer, because phosphorus and potassium is very beneficial to flowers. Especially for rose varieties with a large number of flowers, it may have opened a batch of flowers first, while some buds are emerging at this time.

In this case, fertilizer must be applied, because the blooming flowers will consume a lot of nutrients, and if the unopened buds are not nutritious, the buds will be stunted, and the flowers must be small and not bright enough. If you want the rose to bloom continuously, the fat and water must not be broken.
