Supply mondo grass. If you already have a supply of mondo grass that you've grown or that someone else has cultivated, then you're one step ahead. If not, you'll need to grow a supply of these plants, which are normally sold in pots at nurseries or garden centers. If you are dealing in large quantities, ask a plant expert or plant salesperson to contact wholesale suppliers to buy in bulk. To maintain the health of these plants until you resell them, keep them well-watered and partially shaded.
After you purchase your initial supply of mondo grass, you can continue to reproduce more grass by planting the first batch into a compost soil. Plant individual plants (called sprigs) six to eight inches apart and fertilize with Super-Sod fertilizer 5-10-15, or something similar, once a month. The sprigs will naturally multiply and provide more mondo plants to sell.
Gain an online presence. To sell your grass, you will need an easy way for people to see your product and order. Free blogs like Blogger.com and Wordpress.com provide easy and free ways to publish content. These sites allow you to upload photos of your plants and add captions that may include the plant type and price. Use a high-quality digital camera to take photos of your grass in natural light and upload them to your computer. Blogs have an easy-to-use attachment system that uploads photos in much the same way that you attach files to an email message.
Services like PayPal make it easy for customers to pay for items and make it equally easy for you to deposit payments into a personal or business checking account. You may also accept checks, but you will need to provide an address for customers to mail payments. Consider purchasing a P.O. box from the U.S. Postal Service if you plan to give out a mailing address.
Price the grass. Mondo grass prices vary depending on the type, since there are many types of mondo grass. Arabicus, or black mondo, and silver mist varieties are the most expensive, selling for about $200 for a 3.5-by-3.5-inch box. Dwarf mondo sells for about $78 for the same amount, while Ophiopogon japonicus, or generic mondo grass, sells for just about $65. Price your grass competitively, if not a little cheaper, since your business has yet to build a reputation.
