What kind of fertilizer should be used for rose bush top dressing?
An article on life knowledge, related experience on what kind of fertilizer to use for rose bush top dressing in flower planting, let's get to know it together next.
Now the rose is gradually entering the full bloom period, so many friends are confused, should we continue to top dress now?
We all know that plants need to consume a lot of nutrients to bloom, so we should keep the fertilizer and water充足, but many people also say that fertilizing is not allowed during the blooming period, because too much fertilizer and water can cause the flowers to wither prematurely, shortening the flowering period. Is that really the case? Who should we believe?
So today let's talk about the issue of whether to fertilize during the flowering period, hoping to help you resolve your doubts.
Should we fertilize during the rose flowering period?
Rose is a kind of flower that grows very fast, blooms a lot, and requires a lot of fertilizer and water, and it is also known as "dung basket", but there are times when "dung basket" does not need top dressing.
Many flower friends should have heard of such a fertilizing rule, that is, stop fertilizing when the flower bud shows color, in order to prevent excessive phosphorus and potassium fertilizer from causing premature aging and shortening the flowering period.
Yes, in many flower varieties, there is such a practice, for example, hydrangea, rose of Sharon, peony, peony and other one-season flower varieties, generally after the flower bud shows color, we will stop top dressing and let it bloom naturally.
But for some continuously blooming varieties, such as dwarf morning glory, rose and so on, which bloom in succession, such kinds of flowers should also continue to be top dressed during the flowering period.
What kind of fertilizer should be used for rose top dressing?
Because although some flower buds have already opened, there are still many small flower buds in gestation, flowering consumes a lot of nutrition, the development of small flower buds also needs a lot of nutrition, if the top dressing is stopped after the large flower bud shows color, the small flower bud will turn yellow and fall off due to insufficient fertilizer and water nourishment, and appear fading.
In order to let the small flower bud also open normally, even if some flowers are in the process of opening, it is also necessary to adhere to top dressing.
So back to the rose, is it necessary to continue top dressing now that the rose is in the flowering period?
This also depends on the situation.
Our rose varieties are very numerous, and there will be significant differences in flowering. Some varieties bloom singly, and if trimmed well in winter, the flowering period is very uniform. If it is this kind of rose, after most of the flower buds show color, top dressing with phosphorus and potassium fertilizer once can stop top dressing, just waiting for the flowers to open.
But if it is a variety with multiple flowers, in the case of no thinning of the buds, the flowering will definitely have a sequence, at this time it is necessary to continue top dressing, and it can stop fertilizing after the last batch of small flower buds show color. However, the Green Obsession website suggests that it is better to continue top dressing, because before the last batch of small flower buds open, the large flower buds have consumed a lot of nutrition, and it is basically not too much nutrition, so it is more reliable to be bold in top dressing. In this way, the small flower bud may also bloom larger.
