SIPs: Sub-Irrigating Planters
Building sub-irrigating planters from recycled bottles!
- Repurposing plastic bottles
- Using felt for capillary action: the fabric soaks the water from the bottom reservoir UP to the plant
- Learning what plants need to grow: air, minerals from water, minerals from soil
- ONLY add water to the reservoir after the top layer of soil has dried (1/2 inch)
- When the plant grows bigger, its roots might 'stitch' into the felt and go directly into the water.
- When the roots make contact with the water in the bottom reservoir directly, keep the roots moist.
- With this method, the plant will grow as big as its roots can fit the container!
Making art with fresh leaves and flowers.
- Using natural plant pigments to create a painting
- Collecting leaves and flowers and identifying them
- Learning that the green color in leaves comes from chlorophyll, which captures the sun's energy.
- Hang up your print and notice how it changes color as time goes by.
- The first paints and dyes came from plants more than 5,000 years ago!
