How to use garden edging?

redcamper

When using this merbau border roll, if I were to put a third of it in the ground, will it rot?

Do I need to use pegs or posts when using this to make it stand straight?

What kind of timber oil is recommended and safe if I were to plant veggies/ fruit trees?

Ideally, it would be best to have the roll above ground level, as the constant contact with moisture under the soil will lead to the early onset of decay. I'd suggest driving Growies 50 x 25mm 300mm Hardwood Gardens Stakes into the garden bed behind the edging. You can then attach the edging to the stakes with screws. Remember to pre-drill the merbau to avoid splitting.

A standard exterior or decking oil would be suitable for the edging, will be safe to use, and have no effect on nearby plants or veggies.

Please let me know if you have any questions.

Thanks Mitchell. Can I use this as a circular border for a tree? The soil will be raised as well, hence the soil will be in contact with the back of the roll. Is there anything that I can use as a moisture barrier?

It can be used for a circular border @redcamper. I'd recommend stapling Builder's plastic to the back of it as a moisture barrier.

Great. Are any of the Lattice Makers hardwood garden stakes pre-treated?

We have the Rola Pak 300mm Timber Edging Stakes - 4 Pack which are treated pine @redcamper. None of the hardwood stakes are treated. If you wanted to use the hardwood you could paint the ends going in the ground with bitumen paint to help inhibit decay.

Actually I don't want treated as they would be close to fruit trees/veggies. Should I go for the hardwood then?

Hardwood would be the way to go, @redcamper!
