Easy come, easy grow

On your marks

If you’re installing your window box on the first floor or higher, make sure there are no passers-by or vehicles below whilst putting in place. Avoid installing it in strong winds too.

Get set

Your clever window box comes with arms (like clamps) to fix it securely to your window sill. Extend the arms, then pop the box on your window sill. Tighten the arms with the supplied spanner until the box fits snugly and securely to the window frame. Give it a little wobble to check it’s as tight as can be*. We recommend to regularly check your box is secure, as window frames can shrink and expand with the weather.

*Sorry to get all serious, but legally we need to be clear that secure installation and maintenance is your responsibility.


All you need to do now is take a step back and enjoy your lovely window box. Make sure you water them every other day in summer (half a mugful per plant) or every 3-4 days in winter. Remember you can pop your packaging into the recycling bin.

how to refresh your blooms every season

Out with the old

Don your best gardening gloves and have a bin bag handy. Place your hands down either side of the old refills and gently pull them out. Sometimes mother nature will have started the biodegradation process, slightly mucky, but much better than using plastic!

In with the new

Your refill plants will be delivered at the beginning of every season straight to your door. Just slot your new blooms into the window box. Tighten the arms on your box so it’s still safe and secure in the window frame.

Admire the view

Sit back and soak in the new splash of colour in your window sills. Then simply water them every other day in summer (half a mugful per plant) or every 3-4 days in winter to keep them in tip top condition.
