I started my yearly plant sale yesterday, and it's grown so popular that almost all of my plants sold out the first day. There are going to be some disappointed people the next two days, but I do still have some plants that I will dig fresh for people.
Here are some tips for success:
1. Figure out what plants you need to divide already in early spring, and dig and pot them as they are first emerging. I usually start in late May and my plant sale is mid-June, so my plants look very full and healthy in their pots. Some people dig in fall for the next year's sale, but it's too cold here to leave things in pots over winter.
2. When I transplant into pots I always use rooting hormone to help the plants establish strong roots. You can buy this anywhere, even Walmart. A little goes a long way.
3. When I sell in mid-June a lot of my plants are blooming, so I allow people to walk around the yard and see what my plants look like.
4. I also keep a photo album with picture of plants in bloom that are currently not blooming. So people know what the flower will look like.
5. I make up card ahead of time with plant information and give them to people as they buy plants. I keep these saved on my computer, since a lot of my plants I divide every year.
6. Advertise and spread the word.
All of these things make for a successful plant sale.
