When to plant outdoors?
Plant outside when the danger of frost is over. For me it's at the end of May.
Or start your Ranunculus indoors and plant them outside when it's warm enough. The package suggests starting indoors a month before your last frost date.

- Plant in groups of 10 or more . The packages that I bought have 7 in each. They were suppose to have 8.
- Soak your Ranunculus Tubers in cold water for several hours before planting them.
- Dig a hole in fertile soil - about 2 inches - 5 cm deep, add compost to hole as well.

Caring for Ranunculus
