- Water deeply and evenly: When watering, aim to provide a deep and thorough soak, allowing the water to penetrate deeply into the root zone. This encourages the plant’s roots to grow deeper and promotes overall plant health. Ensure that the entire root ball receives moisture, but be careful not to water excessively.
Fertilizing Silver Dollar Plant
If you are growing the silver dollar plant, Lunaria annua, in fertile soil, you may not need to fertilize it frequently. The plant generally thrives in nutrient-rich soil and can obtain the necessary nutrients from the soil itself. However, if you are cultivating the silver dollar plant in less fertile soils, you may consider providing it with a boost of nutrients.
One way to fertilize the silver dollar plant is by applying a liquid fertilizer diluted to half strength. This can be done once or twice a year during the growing season.

Therefore, it is crucial to be aware of local regulations and guidelines regarding the cultivation of the silver dollar plant.
Remember, if the soil already contains sufficient nutrients, additional fertilization may not be necessary. Before applying any fertilizer, it is recommended to test the soil to determine its nutrient levels. This can help you make informed decisions about whether or not to fertilize the silver dollar plant.
Potting Silver Dollar Plant
The silver dollar plant, Lunaria annua, is not ideal for container gardening. It has a long taproot and can be difficult to transplant. Additionally, it typically does not flower until the second year, making it less suitable for containers. It is best to grow the plant directly in the ground, ensuring it has enough space to spread and establish its root system.
Propagation of Silver Dollar Plant
The silver dollar plant, Lunaria annua, is a versatile and resilient plant that can be easily propagated through seeds. With the right techniques, you can multiply your silver dollar plants and enjoy their unique beauty throughout your garden.
When propagating silver dollar plants, it is best to sow the seeds directly in the ground. Choose a suitable location with well-draining soil and adequate sunlight. Spring or fall is the ideal time for sowing, ensuring the best results after the last frost in the spring.
Spacing the seeds correctly is crucial to allow for proper air circulation and healthy growth. Leave about 15 to 18 inches of space between each seed, giving them room to develop into mature plants.
- Prepare the soil by loosening it with a garden fork or tiller. Remove any weeds or debris that may hinder seedling growth.
- Make small holes in the soil, approximately 1 inch deep.
- Drop a silver dollar plant seed into each hole.
