How to grow Lysimachia nummularia hydroponically? Growing methods and precautions

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

I. Growing methods

1. Water quality

If tap water is chosen for growing, it should be left to settle for more than 2 hours, or used the next day; for hydroponics, 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 nummularia, 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, and it should be gently shaken so the nutrients are evenly distributed. This can also increase the oxygen content, which is beneficial to root growth. The usual amount of nutrient solution is 6 drops per liter of water. Lysimachia nummularia likes a warm and humid environment, so during care it is necessary to frequently spray the leaves with water at water temperature to keep them moist.

3. Water level height

The water for hydroponic Lysimachia nummularia generally must not exceed two-thirds of the container, because too high a water level will affect root growth. At the same time, attention should also be paid to the ambient temperature, which is best controlled between 10-25 degrees. In winter it must not be lower than 5 degrees, as the plant may suffer cold damage.

4. Environment and selection

Hydroponic Lysimachia nummularia should usually be placed indoors in a ventilated and sunny spot, which is beneficial to photosynthesis and reduces leggy growth and yellow leaves. In winter it can be placed outdoors to get 1-10 hours of sunlight, increasing the water temperature and enhancing photosynthesis.

II. Precautions

1. Proper pruning

Lysimachia nummularia has relatively strong vitality, so proper pruning is needed; otherwise, it will affect its appearance because it grows too tall. The correct approach is to prune according to its growth condition. It should not be too dense or too sparse, and apical dominance should be controlled so it cannot grow too tall.

2. Changing water

For hydroponically grown Lysimachia nummularia, after rooting, it generally does not need repotting, as repotting will affect root growth, but attention should be paid to changing the water to avoid water quality deterioration that affects root growth and, in severe cases, may cause root rot.

3. Sensitive to cold

Lysimachia nummularia is sensitive to cold. If it is kept 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 in the following spring. If in the cold northern regions without heating, it can be covered with a plastic bag, then the water poured out, keeping it moist.

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