Hi all,
I'm trying to build a raised garden bed (120x80x40 in cm, about 50x30x15 inches) for growing prebonsai and thickening trunks.
Having the raised bed sit on my clay-heavy top soil (open bottom), do I need to be wary of anything drainage-wise? (would the water pool around/beneath the bed?)
I heard people suggesting to put a drainage layer at the very bottom; however some others said there should be no layers so it can "match" the top soil of the garden.
As for soil, I have bought about 1/3 potting soil, 1/3 compost and plan to fill the rest with top soil (mixing them all together).
Is there anything else (preferably inexpensive), that I should add to the mix?
Additional notes:
1. I live in Europe, zone 8a
2. Going from a small home-made test I made, I would say the soil in our garden consists of about 50% clay, 25% sand and 25% silt
3. Plants I want to grow in the bed:
- JBP, JWP and Scots Pine
- Acer palmatum
- Chinese Juniper and Hinoki Cypress
Thanks for reading! I'd love to hear any type of advice, experiences or thoughts
