Asparagus fern turning old and yellow? Feed it a bit of sour shredded potato water and it is easily solved
Recently, a friend asked the little gardener, her asparagus fern at home had turned yellow and died, what should she do? I asked her to send a picture over, and one look showed there was no saving it, not even if a great immortal came down it would be useless. So, when caring for asparagus fern, we need to deal with it promptly at the early stage of yellowing, so it can turn from yellow back to green and survive lush and green.
1. Feed asparagus fern with shredded potato water, and it turns green again in 1 week
Yellow leaves on asparagus fern can have many possible causes. Insufficient ventilation, excessive light, overwatering and so on can all cause yellow leaves on asparagus fern; these three are fairly common causes. There is another cause of yellow leaves that is often overlooked by asparagus fern owners, which is yellow leaves caused by a lack of trace elements. The little gardener learned a trick from an old predecessor: feed asparagus fern with "shredded potato" water, and it turns green again in 1 week.
2. Feeding asparagus fern with shredded potato water has its own rules of use
The old predecessor said he had discovered this trick worked purely by accident. When he had just started growing flowers, he learned from Tieba to use various kinds of water to make fermented fertilizer, such as rice-washing water and fish-washing water. When he was making sour shredded potato, he also kept that water, put it into a bottle to ferment as usual, left it in the sun for more than a month, and then used it to water the flowers, and found that the yellow leaves faded and the flowers turned green again.
3. Feeding asparagus fern with shredded potato water, the truth is here
The little gardener went specifically to check the information, and it turns out that the water used to soak potatoes contains basic nutrients such as nitrogen, phosphorus and potassium, as well as trace elements such as vitamins, calcium and sodium. These things can all prevent yellow leaves in green plants. If the asparagus fern at home keeps getting yellow leaves, it may also be because the fertilizer used is too single and the pot has not been changed for a long time, leading to a lack of trace elements, and then the asparagus fern will slowly develop yellow leaves.
For this, asparagus fern owners can try watering with fermented potato water. If you think making fermented fertilizer smells too bad, you can also water with Huadongde organic nutrient solution, which is rich in trace elements. It protects and nourishes the roots and effectively prevents yellow leaves on asparagus fern. When growing asparagus fern, when using fertilizer, never use only nitrogen fertilizer such as urea; if the nutrient composition is too single, it will cause yellow leaves.
When growing asparagus fern, if there are no problems with basic care, and the asparagus fern gets more and more yellow as it grows, then it is definitely lacking trace elements. Just like a person whose body lacks nutrition will grow very thin and sallow, at this time, owners can learn the methods above and let the asparagus fern turn green again and survive full of green vitality.
