We're using a garden bed kit and customising it with some castors. But you can make your portable garden bed from anything. A wheelbarrow, an old pallet, a trolley – anything with wheels will do the job!
If you're using a kit, like we are, you're going to need to screw it together. Line up your base pieces on the frame, making sure you leave a gap between the timber so that the soil drains well. Then use the nail gun to attach the timber to the frame of the planter. If you're buying one already assembled, you can skip this step.
Once your planter is assembled, use a pencil to mark up where you want your castors to go – you'll need to do this for every leg.
A pilot hole should be half the length of the screw you'll be using – in our case, it was about 10mm. Drill four per leg – don't forget your protective eyewear for this bit!
Line your castors up with your pilot holes and drill them in. Make sure when you're attaching your casters that they are all pointing in the right direction, otherwise your portable planter won't move properly (no one likes a wonky trolley!)
This is the fun bit! Prepare your bed by half-filling it with some good quality potting mix. Spread it out evenly and lift your plants out of their pots or punnets and place them gently in the soil. If they're a bit stuck, gently tease out the roots. Fill around the plants with more soil and press down so they're snugly in position. Remember to leave enough room between plants for them to grow and expand. Once they're settled, give your plants a generous water and maybe add some seaweed solution to minimise any ‘transplant shock.'
Once your garden bed is planted, find a nice sunny spot in your garden and wheel it into position. And you're done! How easy was that?
