How to top-dress during consecutive rainy days?
The editor will explain the small experience of plant cultivation on how to top-dress during consecutive rainy days. Let's learn about it together below.
A flower lover involved in creating a flower wall yesterday said that the original fertilizing plan had to be suspended due to continuous rain and no opportunity to water the plants. I believe many flower lovers have the same idea, "It rains every day, the outdoor roses don't need to be watered, there's no chance to fertilize, let's wait for sunny weather!"
In fact, this idea is very wrong. The more consecutive rainy weather there is, the more attention we should pay to top-dressing our potted roses. Because continuous rain washes away many nutrients in the potting soil, causing a significant loss of nutrients in the soil. Our rose seedlings are in a period of vigorous growth, which is exactly when they need a large amount of fertilizer and water. If topping up fertilizer is not timely, it is easy to have blind branches. So, what should we do?
Methods of top-dressing during consecutive rainy days
During consecutive rainy weather, we mainly use the following two methods to top-dress our roses.
1. broadcasting
The broadcasting method of top-dressing is often used for roses planted in the ground. Generally, before or after a temporary stop of rain, fertilizer is scattered around the rose roots. When it rains again, the fertilizer is dissolved by the rainwater and enters the soil, where it is absorbed and utilized by the rose roots.
Broadcasting can not only be used for top-dressing roses planted in the ground but also for potted roses, but attention should be paid to the amount and location of application.
For potted roses, due to the small pot area and the close proximity of branches and leaves to the pot surface, it is easy to scatter the fertilizer on the main roots of the rose or get it on the leaves. Fertilizer堆积 on the main roots of the rose can easily cause fertilizer damage and result in black stems. If it gets on the leaves, it can also cause leaf burn.
Therefore, when broadcasting fertilizer, it is important to scatter it mainly around the edge of the pot, evenly, avoiding piling it together, and any fertilizer that gets on the leaves should be promptly cleaned off.
For roses planted in the ground, the amount of scattered fertilizer is not very particular. A distance from the roots, one mature rose can be top-dressed with 30g-50g of fertilizer each time. The general principle is to use more for larger seedlings and less for smaller ones.
However, for potted roses, it is necessary to control the amount. Generally, for a 1-gallon pot, use 1-2 grams; for a 2-gallon pot, use 2-3 grams. Use more for larger pots and less for smaller ones.
For新手 gardeners, it is recommended to use less rather than more when broadcasting fertilizer, applying it in small, frequent doses.
2. Foliar application
If you are worried about fertilizer damage, you can also use foliar application. However, foliar application needs to be done after the rain stops, as the absorption is poorer when the leaves are wet.
Foliar application is relatively safer and simple. Dilute water-soluble fertilizer in water, pour it into a spray bottle, and spray it on the leaves of the rose, making sure to spray both the front and back of the leaves, as the back has a stronger absorption capacity.
The absorption concentration of foliar spray fertilizer should be according to the normal dilution concentration for watering. For example, the "Flower多多 series" fertilizer can be sprayed at a concentration of 1000 times, and the nutrient solution should be diluted as per the instructions before spraying.
The frequency of foliar application can be slightly higher, especially during consecutive rainy weather. It can be applied every 3-5 days to maintain sufficient fertilizer for the roses.
The above comprehensive method explanation of how to top-dress during consecutive rainy days, I hope it can serve as a brick to attract jade and solve your problems with green plants.
