Few plants can boast such a deep history while also presenting modern horticultural challenges quite like the lotus. This aquatic plant is fascinating not only for its aesthetic value but also because its cultivation requires special attention, especially if you want to grow it in a raised bed.
The lotus seed marks the beginning of the plant’s life, and without proper preparation and careful planting, it struggles to germinate and develop. Using a raised bed as a cultivation method offers unique advantages but also demands thorough planning to fully meet the needs of this aquatic plant.
One of the most crucial steps in growing lotus from seed is selecting the right species, which must suit not only the local climate but also legal regulations. In the EU and Hungary, only lotus species that are neither invasive nor protected are legally permitted. In my opinion, it’s worth choosing Nelumbo nucifera (Asian lotus) or Nelumbo lutea (American yellow lotus), as these are widely available and adapt well to temperate climates.
It’s important not to experiment with unknown or unapproved species, as this can have legal consequences and may disrupt your garden’s ecological balance. Ask yourself: “Which species will best withstand local conditions and raised bed cultivation?” This question helps focus your choice.
When preparing lotus seeds, physical treatment must not be overlooked. The seed coat is thick and hard, so mechanical pre-treatment is necessary to initiate germination. I personally always recommend gently removing or sanding down the upper part of the seed coat to allow the sprout to break through more easily.
This process not only shortens the germination time but also significantly improves success rates. Think of the lotus seed as wearing a natural “armour” that must be breached to bring it to life.
Growing lotus in a raised bed requires special attention because the plant is water-demanding, and water quality plays a key role alongside soil in its development. Therefore, when constructing the raised bed, installing a waterproof layer and planning the appropriate depth should be among the first steps.
In my view, the best way to create a waterproof layer is to use a thick, durable plastic sheet or a specialised pond liner that prevents water leakage. Regarding depth, lotus roots feel comfortable in at least 30-50 cm of water, so it’s advisable to maintain this optimal depth in your raised bed as well.
Timing the planting is crucial, especially in our climate where spring frosts can still pose a threat. Only sow lotus seeds when the soil temperature consistently stays above 15-18 °C and the risk of frost has passed. This usually happens around late April or early May.
Ask yourself: “What is the temperature trend at the raised bed, and when will it be warm enough for safe seed planting?” This question helps avoid halted germination or seed damage.
Germinating lotus seeds is initially a patient but well-planned process. First, soak the seeds in lukewarm, clean water for 24-48 hours. This pre-soaking stimulates internal seed processes and prepares them for germination.
I personally always recommend keeping the water temperature no lower than 20 °C, as cold water slows germination. Next comes mechanical germination treatment: gently sanding or cutting the seed coat to help the sprout break through. This step is especially important if you want faster germination.
During germination, temperature and light conditions must be controlled. The ideal temperature range is 20-28 °C, which allows seeds to sprout quickly and healthily. I always advise avoiding direct strong sunlight, as it can overheat the seeds, while a bright but shaded spot is best.
Once the seeds have sprouted, plant them in the water-filled section of the raised bed. It’s important to secure the roots properly so they don’t drift away and can develop stably. You can use fine silt or gravel around the roots for this purpose.
In summary, growing lotus from seed in a raised bed is a conscious and carefully planned process, with every step important. I believe that if you follow the preparation and germination protocol step by step, you can successfully cultivate healthy lotuses in your garden.
One of the most important aspects of lotus care is ensuring optimal water quality and depth, especially in a raised bed where natural water sources are not available. As aquatic plants, lotuses require continuous water coverage, but stagnant water must be avoided as it can cause root and rhizome rot.
Therefore, it is essential to regularly check the water level in the raised bed and refresh the water as needed. Ideally, the water depth should range between 20 and 40 centimetres, allowing the plant’s roots to fit comfortably without drowning.

Providing adequate nutrient supply is key to abundant flowering and healthy growth of lotuses. In raised beds, particular care must be taken to ensure fertilisation is natural and balanced, as excessive chemical fertilisers can harm the plant and degrade water quality.
Therefore, I recommend using slow-release, natural fertilisers that gradually provide the necessary nutrients without overburdening the soil or water.
Remember, always tailor nutrient supply to the plant’s needs! What natural fertilisers have you tried, and what results did you see? Share your experiences with me!
Lotus plants go through different growth stages, each with varying water and light requirements. In a raised bed, it is important to monitor these changes and adjust watering and light conditions accordingly.
In the early spring stage, the lotus is sensitive to too much water and light, whereas during the active summer growth period, it requires more frequent watering and full sunlight. However, excessive heat stress, especially on hot summer days, can damage leaves and flowers, so providing shade nets or natural shade during the hottest hours is advisable.

Preventing pests and diseases is especially important in lotus care, as the enclosed environment of a raised bed can easily favour the spread of infections. Minimising chemical treatments is advisable, as these can harm the aquatic ecosystem and the plant’s natural development.
Therefore, I recommend using biological control methods that employ natural substances and living organisms to keep pests in check.

Ensuring the lotus’s winter dormancy is essential for a successful next season. In raised beds, regulating water level and temperature is crucial, as too low temperatures or drying out of water can damage the rhizomes.
Therefore, it is important to properly cover and insulate the raised bed during winter, preferably with natural materials such as straw or wood chips, which preserve soil temperature and prevent frost damage.

At the end of winter and early spring, pruning and cleaning are essential to support lotus renewal. This process not only encourages healthy growth but also reduces the risk of pests and diseases.
Removing old, dried leaves and stems allows the plant to develop more easily and lets fresh shoots receive more light. When pruning, be careful not to damage the rhizomes, which are vital to the plant’s life.

Collecting and properly storing lotus seeds is a vital step for long-term sustainability. Seeds should be gathered at the end of flowering when the seed pods have dried and hardened, taking care not to damage them.
To preserve freshness, store seeds in a cool, dry place in an airtight container. This ensures that cultivation can start the next season with a high germination rate.
| Step | Action | Note |
|---|---|---|
| 1. | Collect fully dried lotus seeds. | Be careful not to break or crack them. |
| 2. | Clean seeds from dried pods and other debris. | Cleanliness is important for long storage. |
| 3. | Store seeds in a dry, cool place in an airtight container. | Avoid humid, warm locations. |
| 4. | Check seed condition and germination ability annually. | This helps detect deterioration in time. |

If you love lotuses grown in raised beds, you know how much care and attention these beautiful aquatic plants require. Careful water and nutrient management, watering and light adjusted to growth stages, and the use of natural protection methods all contribute to keeping your lotus healthy and blooming for many years.
