How to fertilize roses during consecutive rainy days?
Life knowledge series, about the content of planting green plants and flowers on how to fertilize roses during consecutive rainy days, please see the detailed introduction below.
This rain has been going on for several days, and the weather forecast for the next week is still dominated by the word 'rain'. Early April is the time when roses grow leaves and flower buds rapidly, requiring a large amount of fertilizer and water. With the rain every day, it is undoubtedly a headache for rose lovers. How should we fertilize then?
You might say that foliar application can be used, but it seems that the rain won't stop, and even foliar application can't find an opportunity. What should we do? Let's give you some tips today.
What is the impact of consecutive rainy days on potted roses?
Consecutive light rain will have a relatively small impact on the growth of potted roses, mainly causing disease and insufficient light, but it doesn't affect the nutrients in the potting soil much.
However, if it rains heavily for a long time, the impact on potted roses is significant. Due to the repeated washing of rainwater, a large amount of nutrients in the potting soil will be lost, and if fertilizers are not replenished in time, roses may show signs of nutrient deficiency.
Methods of top-dressing during consecutive rainy days
If there is an opportunity to top-dress on the leaf surface during consecutive rainy days, foliar top-dressing can be used to supplement nutrients.
Specific steps:
Dilute water-soluble fertilizer with water, and spray evenly on the front and back of the leaves with a spray bottle. The back of the leaves has stronger absorption capacity.
Just foliar top-dressing is not enough; we can also use the method of broadcasting fertilizer to top-dress. The chosen fertilizer is also fast-acting water-soluble fertilizer. When broadcasting, pay attention to the amount and location.
Usually, the concentration of water-soluble fertilizer used for root irrigation is 1000 times. When broadcasting, we can use a small scoop, and for a 2-gallon pot, you can broadcast 2-3 grams of water-soluble fertilizer around the edge of the pot.
When broadcasting, try to spread it evenly around the edge of the pot, not in a pile, and not on the main branches and roots, as this can easily cause fertilizer damage.
Also, be careful not to let it fall on the leaves and the core of the branches when broadcasting, as this can easily cause fertilizer damage. If it accidentally falls on the leaves and the core, clean it up immediately or rinse it off with water to avoid fertilizer damage.
After broadcasting, the fertilizer will enter the soil with the rain and be absorbed by the roots.
What if the luck is good, and the rain stops after broadcasting fertilizer, and the fertilizer doesn't dissolve?
Then it is recommended to check the weather forecast. If it rains again soon, then there's no need to worry. If it's sunny from then on, manually water the plants by浇透 (thoroughly watering) with a watering can.
It is important to note that watering must be thorough and not stop just when the fertilizer dissolves, as this also carries a high risk. Make sure to thoroughly water, as the water can take away many of the residual salts and bacteria in the soil, giving the soil a new healthy environment.
