If you find that transporting compost into your pots using a trowel takes you forever, make a DIY compost scoop from an old milk bottle. Cut the bottom of the bottle, then cut diagonally on the side with the handle to make the opening. Then you’ve got a handy wide compost scoop.
Alternatively, cut it in the same position, turn it so the top of the bottle is downwards, and you can use it to plant in. Add a whole at the flat, back section and attach it to a wall or fence, just ensure you add some drainage holes.
