My impatiens I started 2/7/07 are growing gangbusters. Will be large enough to pich them and wanted to make more.

i use the oasis method for geraniums with excellent results.

I have used a strawberry container with soiless mix to root begonias with excellet results.

Was wondering now that I have 8 to 9 weeks before last frost about pinching these impatiens, but don't know about using water rooting vs the oasis vs the strawberry mini prop arrangement.

What has been the most successful prop way? I only have about 40 plants right now.
