Why is it necessary to apply long-acting fertilizer to roses at the end of summer and the beginning of autumn?
If you want to know why it's important to apply long-acting fertilizer to roses at the end of summer and the beginning of autumn for some small gardening experiences, detailed content will be shared next.
Regarding rose fertilization, it was mentioned yesterday that May to June is the first good opportunity to officially fertilize roses. This fertilization is mainly to replenish the nutrients consumed by the first batch of flowers and also to store nutrients for roses, laying a solid foundation for a smooth summer.
Then, apart from this official fertilization, there are two more formal fertilization opportunities during the entire growth cycle of roses. Do you know which two times they are?
Firstly, although roses can bloom all year round, they often are in a semi-dormant state during the summer due to the hot weather, and the blooms are not as good.
And in winter, due to the cold weather, roses in frost regions in our country will hibernate.
In spring and autumn, the temperatures are moderate, which are the best times for roses to bloom. Many rose varieties often have more standard autumn flowers than spring, mainly due to the temperature influence, which will be shared more in the future.
We know that spring and autumn are the times when roses bloom in large numbers, so fertilization should follow the growth rhythm of roses.
The first official fertilization is arranged after the first batch of flowers, so the second fertilization should be at the end of summer and the beginning of autumn.
Why is it necessary to apply long-acting fertilizer to roses at the end of summer and the beginning of autumn?
Think about how much your roses have suffered in the summer and how much nutrient consumption there is. In autumn, roses start to grow rapidly and bloom again, which also requires a lot of nutrients.
Therefore, we choose to give roses a second formal fertilization at the end of summer and the beginning of autumn, the purpose of which is:
To replenish the consumption of roses in summer and to store nutrients for the blooming of autumn flowers.
This is the second formal fertilization
So when should the third one be?
Many people think it should be after the autumn flowers.
Yes, and no!
Yes, because fertilizing after the autumn flowers can help roses quickly restore nutrient reserves, but no, because after the autumn flowers, the temperature gradually drops, the growth rate of roses slows down, and they eventually enter a dormant period.
And if we do formal fertilization after the autumn flowers, it's easy for the fertilizer to be wasted due to the slow growth of roses.
The time for the third formal fertilization should be in winter
It can be combined with potting changes, placing organic fertilizer at the bottom of the flowerpot as a base fertilizer, or it can be mixed with soil.
If the roses are planted in the ground, you can directly bury fish intestines, bone meal, animal manure, etc., within a range of 20-30 cm from the roots as fertilizer for the rose growth in the following spring.
In winter, when the temperature is around 0°C, unfermented organic fertilizer can be used, but be sure to avoid direct contact with the roots!
If the pot is not changed in winter, then the third fertilization should be carried out when the roses sprout in spring.
Have you remembered the times for the three formal fertilizations of roses?
Of course, the use of fast-acting fertilizer should be throughout the entire growth period of roses.
That's the detailed explanation of why it's necessary to apply long-acting fertilizer to roses at the end of summer and the beginning of autumn, this is the second formal fertilization, and the third formal fertilization should be in winter. I hope this article can bring you some help in green plant management!
