The money tree plant (Lunaria annua) is a hardy biennial that is also called the honesty plant, moonwort and silver dollars. The money tree plant is considered a dual-purpose plant; it produces a nectar that is popular with butterflies, and its unusual oval, translucent seed pods are a striking addition to dried flower arrangements. Propagating money plant from seed is easy and if the seed pods of the money plant are left on the plant, it will reseed itself and return again the following year.
Put seed starting potting mix into a seed germination tray until it's approximately 1/2 inch from the top of the rim. Use the base of a 4-inch pot or a small block of wood to compress the potting mix all around in the germination tray.
Make shallow 1/8 inch deep rows in the germination tray. To do this, you can use the long end of a 12-inch ruler, a pencil or any object which can create a straight line. Space each of the rows 2 to 3 inches apart from each other.
Plant the money tree plant seeds in the shallow rows at a rate of two to three money plant seeds every 1 to 2 inches. Then, cover up all the money tree plant seeds with approximately 1/8 inch of soil. Pat the soil down over the planted rows. Use a fine spray of water to water the soil thoroughly.
Put the germination tray in a brightly lit area in your home. Between 8 and 10 hours of non-direct sunlight daily is ideal. The temperature should be between 18.3 and 21.1 degrees C. Mist the soil with water as needed to keep it moistened, but never sodden. Germination of money tree seedlings should begin within 12 to 15 days.
Thin out the money tree plant seedlings, once they have a set of leaves, to one money tree plant seedling every 6 inches. Transplant the money tree plant seedlings when they have at least three sets of leaves apiece and there is no further danger of frost expected in your growing region.
Dig up the planting area for the money tree plants by using a garden fork, or a shovel and turning over the soil to a depth of between 6 and 8 inches. Make sure you remove all weeds and their roots as you cultivate the planting area.
Create rows and space each of the rows about 14 to 16 inches apart. However long you want to create each row depends on how much space you have available in the planting area.
Dig holes for each money tree plant seedling that is large enough to accommodate the root system. Then, dig out the money tree plant seedlings using a large metal spoon.
Place a money tree plant seedling into one of the previously dug holes. Push in soil around the seedling tamping it down as you go. Then, thoroughly water each of the money tree plant seedlings. Once the money tree plants become established, you only need to provide them moisture during periods of drought.
Metro Parks of Butler County, Ohio suggest that you plant money plants where they will receive at least four to six hours of sunshine daily.
