What to Do When Water Lettuce Leaves Dry Out? Cause Analysis and Solutions

Flowers & Gardening 0 views
This green plant is also called water lettuce (Pistia stratiotes), belonging to the Araceae family. It lives in water, and both male and female parts are on the same plant. It grows very quickly. It originates from Brazil, and now most of it lives in tropical regions and areas along the north and south latitudes, and it can also be seen in many rivers in China. Some plant enthusiasts also keep this plant at home, and sometimes its leaves dry out. How should this be handled?

I. Causes

1. Insufficient light. During its normal growth process, it cannot do without a certain amount of light. If you place it in too dark an area at home and don't give it light for a long time, its leaves will of course dry out.

2. Poor ventilation. If you place it in a poorly ventilated spot at home with no airflow, the O2 in the water will be quickly consumed, and its leaves will turn yellow and dry out.

3. Temperature too low. It likes a warm environment. In winter, if the weather is too cold, it cannot make it through the winter safely. Its physiological activities slow down, and its nutrient absorption rate also weakens. Its leaves will dry out, and in severe cases it may even drop its leaves to preserve nutrients.

4. Too much fertilizer. If you add a large amount of fertilizer to promote its growth, it will instead be toxic to it, causing its leaves to dry out.

5. Changing the water too infrequently. If you don't change the water for a long time, but the O in the water2has already been absorbed, with none left for it to take in, and at the same time the number of microorganisms in the water increases, its roots will rot and its leaves will also dry out.

You need to carefully figure out the specific cause of the leaves drying out before taking specific measures. If it's a lack of fertilizer, add a specialized nutrient liquid; if it's a lack of light, place it in an area at home with light and airflow.

II. Daily Care

1. It likes places with high temperature and high humidity, and its resistance to severe cold is not very high. Generally, it can grow well between 15 and 45 degrees. If it is below 10 degrees, its roots will rot, and if it is below 5 degrees, it will die.

2. It likes clean water. If it is living water that flows frequently, it is good for its growth.

3. It blooms in summer, and only needs 60 to 80 days to produce fruit. If you live in the Guangxi-Guangdong area, it can grow year-round and can safely make it through the winter. After its fruit is fully ripe, it will split open and fall into the water by itself, then take root and grow the following year.
