Nelumbo nucifera, commonly known as Sacred Lotus or Lotus Root, is a stunning aquatic plant cherished for its beautiful flowers and edible roots. Originating from Asia, it thrives in water gardens and ponds, making it a popular choice for ornamental and culinary purposes.
Everything it needs
9 essentials at a glance
Watering
Nelumbo nucifera requires consistent moisture, ideally submerged in water.
During the growing season (spring and summer), keep the water level at least 4-6 inches above the soil. Water should be changed regularly to prevent stagnation. In fall and winter, reduce watering as the plant enters dormancy. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
The Sacred Lotus thrives in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placement is in a pond or water garden where it can receive ample sunlight without obstruction. It can tolerate partial shade but may result in reduced flowering and growth.
Soil
This plant prefers a heavy, loamy soil with a pH range of 6.0 to 7.5.
Good drainage is essential, so a mix of clay and organic matter is recommended. A specialized aquatic potting mix can be used to ensure proper growth and stability.
Humidity
Nelumbo nucifera thrives in high humidity levels, ideally above 50%.
To increase humidity, consider placing a humidifier nearby or grouping plants together. Signs of humidity stress include browning leaf edges and stunted growth.
Temperature
The ideal temperature range for Sacred Lotus is between 70°F to 90°F (21°C to 32°C).
It is hardy in USDA zones 4-10 but can suffer in temperatures below 50°F (10°C). Protect the plant from frost during colder months by moving it indoors or covering it.
Fertilizing
Use a slow-release aquatic fertilizer with an NPK ratio of 10-10-10 or similar.
Fertilize every 4-6 weeks during the growing season, but avoid fertilizing in fall and winter. Signs of nutrient deficiency include yellowing leaves and poor growth.
Pruning
Prune the Sacred Lotus in early spring before new growth begins.
Remove any dead or damaged leaves and spent flowers to encourage new growth. Use clean, sharp scissors or pruning shears to prevent disease transmission.
Repotting
Repot every 2-3 years or when the plant becomes root-bound.
Choose a pot that is 2-4 inches wider than the current one. Signs it needs repotting include roots growing out of the pot's drainage holes. Carefully remove the plant, trim any damaged roots, and place it in fresh soil.
Propagation
Propagation can be achieved through division or seeds.
For division, wait until the plant is dormant in late fall or early spring, then carefully separate the rhizomes, ensuring each has at least one growing point. For seeds, soak them in warm water for 24 hours, then plant them in a shallow container with soil, keeping them submerged in water until they sprout.
When it's unhappy
Yellowing leaves
Why it happens
This can be caused by over-watering or nutrient deficiency.
How to fix it
Check the water level and reduce if necessary. Fertilize with a balanced aquatic fertilizer to address nutrient issues.
Root rot
Why it happens
Root rot is typically caused by stagnant water or poor drainage.
How to fix it
Ensure proper water levels and change the water regularly. If root rot occurs, remove the plant, trim affected roots, and repot in fresh soil.
Wilting leaves
Why it happens
Wilting can occur due to under-watering or extreme temperatures.
How to fix it
Increase watering frequency and ensure the plant is in a suitable temperature range.
Poor flowering
Why it happens
Insufficient sunlight or nutrient deficiency can lead to reduced flowering.
How to fix it
Ensure the plant receives at least 6-8 hours of sunlight daily and fertilize regularly during the growing season.
Browning leaf edges
Why it happens
This is often a sign of low humidity or over-fertilization.
How to fix it
Increase humidity levels around the plant and reduce fertilizer application.
Care through the year
Spring
In spring, begin fertilizing as new growth appears. Ensure the water level is adequate and remove any dead foliage from the previous season.
Summer
During summer, maintain consistent water levels and fertilize every 4-6 weeks. Monitor for pests and ensure the plant receives full sun.
Fall
In fall, reduce fertilization and prepare the plant for dormancy. Gradually lower the water level as temperatures drop.
Winter
In winter, keep the plant in a protected area if grown in pots. Reduce watering and ensure it does not freeze.
Toxicity & Safety
The Sacred Lotus is considered non-toxic to pets and children. However, ingestion of large quantities may cause mild gastrointestinal discomfort. All parts of the plant are edible, but the seeds and rhizomes are most commonly consumed.
