How to Grow Lysimachia in Water: The Latest Cultivation Methods and Precautions

Lysimachia, also known as mirror grass, has extremely high medicinal value in addition to its ornamental appeal, and many people choose the water cultivation method when growing it, because it is not only clean but also looks quite beautiful. So how should water-cultivated Lysimachia be grown? What should be paid attention to? Let's take a look together,

I. Cultivation Methods

1. Water Quality

If tap water is chosen for cultivation, it should be left to settle for more than 2 hours, or used the next day; for water cultivation, the main thing is that the water quality is clean. Note that in order to prevent water quality deterioration from causing root rot in Lysimachia, the water needs to be changed in a timely manner: in spring and autumn generally change the water once every 5-7 days, in summer every 3-5 days, and in winter once every ten days to half a month.

2. Nutrient Solution

After each water change, to ensure sufficient nutrients, nutrient solution needs to be dripped into the water, then shaken gently to distribute the nutrients evenly; this also increases the oxygen content, which is good for root growth. The usual amount of nutrient solution is 6 drops per liter of water. Lysimachia likes warm and humid environments, so during care the leaves should be frequently sprayed with water at the same temperature to keep them moist.

3. Water Level Height

The water for water-cultivated Lysimachia generally should not exceed two-thirds of the container, because a water level that is too high will affect root growth. At the same time, pay attention to the ambient temperature; it is best kept between 10-25 degrees, and in winter it must not be lower than 5 degrees, as the plant may suffer frost damage.

4. Environment and Selection

Water-cultivated Lysimachia should usually be placed indoors in a ventilated, sunny spot, which is good for photosynthesis and reduces leggy growth and yellow leaves. In winter it can be placed outdoors to sun for 1-10 hours, increasing the water temperature and enhancing photosynthesis.

II. Precautions

1. Proper Pruning

Lysimachia has fairly strong vitality, so it needs proper pruning; otherwise it will affect its appearance by growing too tall. The correct approach is to prune according to its growth condition: it should not be too dense, nor too sparse, and apical dominance should be controlled so it does not grow too tall.

2. Changing the Water

For water-grown Lysimachia, after it has rooted there is generally no need to repot, as repotting will affect root growth, but attention must be paid to changing the water to avoid water quality deterioration that affects root growth and, in severe cases, may cause root rot.

3. Sensitivity to Cold

Lysimachia is sensitive to cold. If it is cared for outdoors in winter, the water can be poured out and the plant placed in a south-facing, sunny and wind-sheltered spot, where it can overwinter safely; some leaves may die off, but the roots will sprout again the following spring. If it is in a northern region without heating, a plastic bag can be used to cover it, then the water poured out, keeping it moist.

The above is an introduction to the water cultivation methods and precautions for Lysimachia. I hope it can help you, and if you want to learn more related knowledge.
