Indoor Tulips . . . Step 1 - Fill a glass container about 1/3 of the way with glass marbles or decorative rocks... Step 2 - Set the tulip bulb on top of the marbles or stones; pointed end UP. Add a few more marbles or rocks so that the tulip bulb is surrounded but not covered (think support). . .Step 3 - Pour fresh water into the container. The water shouldnt touch the bulb, but it should be very close, so that the roots will grow in and vola tulips inside!
