- Sell your plants at a lower price than major retailers like Wal-Mart
- Constantly have a good selection of healthy plants
- Do so at a lower price than what it costs you, so you can make a profit. If you can’t do that, then there is no way to succeed.

How many houseplants do you plan to sell? How many varieties?
I wouldn’t carry less than 10 varieties, at least 3 or 4 of each variety, at any given time.
