In winter, everything withers, temperatures drop, and the growth rate of potted plants will also slow down. This does not mean that we can neglect their maintenance. On the contrary, reasonable fertilizing is the key to ensuring the healthy growth of potted plants in cold seasons. This article will introduce in detail how to fertilize potted flowers in winter, helping your plants to survive the winter warmth.
Choosing the right fertilizer1. Nitrogen fertilizer: Nitrogen fertilizer is the main nutrient element for plant growth, which helps plants grow luxuriantly. But in winter, due to the low temperature, the growth rate of plants slows down, and excessive nitrogen fertilizer can lead to excessive growth of plants, affecting their overwintering. When fertilizing in winter, fertilizers with low nitrogen or no nitrogen should be chosen.
2. Phosphate fertilizer: Phosphate fertilizer helps plant root development and improves the cold resistance of plants. In winter, fertilizers high in phosphorus can be chosen, such as potassium dihydrogen phosphate, etc.
3. Potash fertilizer: Potash fertilizer can enhance the disease resistance and cold resistance of plants. In winter, applying an appropriate amount of potash fertilizer can help plants survive the cold season.
Fertilizing time and method1. Fertilizing time: The best time for fertilizing in winter is generally on sunny afternoons when the temperature is relatively high, as plants have a stronger ability to absorb fertilizers.
2. Fertilizing methods: According to the type and growth condition of the potted plants, the following fertilizing methods can be adopted:
(1) Foliar application: Dilute the fertilizer and spray it evenly on the leaves of the plant. This method is suitable for light-loving plants, such as Epipremnum aureum, Chlorophytum comosum, etc.
(2) Root zone fertilizing: Apply the fertilizer near the roots of the plant, avoiding direct contact with the roots. This method is suitable for most potted plants.
(3) Buried application: Bury the fertilizer in the soil, which is suitable for slower-growing plants, such as succulent plants, etc.
Precautions for fertilizing1. Control the amount of fertilizer: In winter, plants grow slowly, and the amount of fertilizer should be reduced appropriately to avoid fertilizer damage.
2. Avoid fertilizing too frequently: In winter, plants grow slowly, and the frequency of fertilizing should be reduced, generally fertilizing 1-2 times per month.
3. Pay attention to the safety of fertilizing: When fertilizing, ensure that the fertilizer is evenly distributed, avoiding excessive fertilizing in localized areas that can cause fertilizer damage.
4. Observe the growth condition of the plant: After fertilizing, pay attention to the growth condition of the plant. If the plant shows signs of malnutrition, slow growth, etc., the fertilizing plan should be adjusted in a timely manner.
Fertilizing potted flowers in winter is the key to ensuring the healthy growth of plants. By choosing the right fertilizer, mastering the correct fertilizing time and method, and paying attention to the precautions for fertilizing, I believe your potted plants will surely grow robustly in the cold winter. I hope this article can provide help for your potted plant maintenance.
