Indoor Tulips . . . Step 1 – Fill a glass container about 1/3 of the way with glass marbles or decorative rocks. Clear glass will enable you to watch the roots develop . . . 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.
