At present, the Sunshine Rose in some areas is about to enter the hard core stage, and the fruit expansion rate is gradually slowing down. Some growers are worried that the fruit will be too small and cannot be compacted, so they increase the amount of fertilizer, which is not advisable.

Firsy, fertilizer application before the hardcore stage

The current fertilizer application needs to be determined based on the growth of the fruit.

1. If the fruit grows normally, the fertilizer used is still mainly Monband® GuYu® 30-10-10 high nitrogen fertilizer. There are still a few days before the hardcore stage to promote the continued expansion of the fruit, and use Monband® MBT PULI-NANO(MBT SUS) to maintain the root system.

2. If the fruit expands quickly, even if it has not reached the hard core stage, you can replace part of the Monband® GuYu® high nitrogen fertilizer with Monband® GuYu® 20-20-20 balanced fertilizer in advance to increase the amount of potassium fertilizer in advance, which is conducive to early sugar production and early market launch.

3. For plots with smaller grains, more obvious fruit powder, and poor fruit expansion, check whether there is a problem in the field. First, check whether the soil moisture is sufficient. The field humidity should be maintained at around 70% during the fruit expansion period.

Secondly, check whether the root system is healthy and whether there are many rotten roots. If the root system is poor, you can use Monband® GenMeng® to promote new root germination. In addition, observe whether the new shoots are growing vigorously. Under normal circumstances, during the first expansion period, nutrients mainly flow to the fruit, and the new shoots are not growing vigorously. If the growth is severe, it is necessary to focus on controlling the growth.
