THE DEVIL SUGGESTS
Build a garden planter
Make a planter sized for a bare corner, doorstep or balcony, then fill it with something you genuinely want to grow. Good drainage and a place that gets the right amount of light will do more than fancy timber.

Do it
- Choose a spot and measure the available space.
- Pick weather-suitable materials and a simple shape.
- Build the box with drainage holes or gaps.
- Line it if needed and fill it with suitable compost.
- Plant it and make a simple plan for watering.
What next?
Keep the useful notes, photograph the result if there is one, then go and find something else to do.
