My “maximum compost” method for starting out. Add a lot to make new beds, then very little in subsequent years.
The cardboard is only for this stage of smothering weeds – keep them in the dark and they expire! Then you don’t need to lay any more cardboard, once there are no weeds.
You can use less compost. Lay thick card on weeds then 2in/5cm compost asap in early spring, and wet the card if it’s dry. Then use a trowel to ‘cut’ potato size holes in the card and a little into the weedy soil below, to pop in a seed potato. This can give some harvest by summer, while killing weeds too, but you must pull any weeds you see 🙂
If you do not have access to any compost, use old leaves, manure at least half-decomposed – or at limit the one month old you see in this video. Results in year one will be less brilliant than in subsequent years, but you will be clearing weeds easily as well as having a harvest.
Vegetables like potatoes, squash and zucchini grow well though cardboard and less-perfect compost. After they finish you could plant kale or leeks etc.
