The Q&A Archives: Plant In A Tube

Question: Hi, I'm a student in 10th grade. I had an awesome science teacher who is going to move away and I would like to try to plant some flowers in a test tube. I don't know how the drainage will work or won't work. Can you tell me if it will work, or what I would need to do to make it work?

Answer: Your idea sounds terrific! If you think about the growing environment within the test tube as being similar to a sealed terrarium, you can see that it will work. The trick is to put a cork in the top of the test tube so the moisture will be recycled back into the potting soil. Start with moistened potting soil and squeeze it in your hand to remove excess moisture. Place it in the test tube and tamp it down, then plant something small (like Baby's Tears). Cork the top, tie a ribbon around it, and present it to your teacher.

p.s. I'm glad you had such an awesome science teacher!
