Plant a Rainbow

During lockdown, the rainbow became a symbol of hope and gratitude for the hard-working NHS. The nation displayed rainbows in windows and gardens, filling dreary days with a splash of colour.

Now, we're looking towards a brighter futures. Schools and communities are open once again. And there's no better time to get growing with much-missed friends and families.

So, if you have a spare raised bed in your or an empty pot, follow our plant suggestions and grow yourself a rainbow!

All the mentioned plants are available to buy as plug plants from your local garden centre. And these are sure to give your school and community gardens a instant burst of colour.

The plants have similar needs in terms of soil type and watering. So, they should grow well together in containers.

Simply water them well and feed them regularly, and you should have a gorgeous display for late-spring and summer!
