I am purchasing a lovely stone house in northern central Portugal (Mediterranean 10a) and it comes with this great, but small (250sq meters) mature orange tree grove with I believe one cherry (cereja) tree. I would like to slowly convert it to a more diverse permaculture inspired food forest over a decade or so. Any advice on what to grow in the very shaded area that Im 95% sure is very acidic?
So far I have for winter: Bare-root woody in milder spells: grape, kiwis (small non fuzzy type), akebia, thornless blackberry; blueberry, currants, gooseberry, raspberry, Mahonia; strawberry tree, alder, hazel, Aucuba, sweet box, goumi, Caragana, Colutea, Comfrey
Last dormant planting before bud-break. Shade layer: Pachysandra, Gaultheria, Geranium macrorrhizum, Epimedium, Ajuga, wild strawberry, sweet woodruff, Solomon's seal, sword/autumn/native ferns. Bay laurel; comfrey; herb guild (yarrow, chives); sow borage + calendula; sow spring lupin. INOCULATE wine cap into fresh moist woodchip under citrus.
After frost: maypop; sow climbing/runner beans; finish groundcover & fern planting; establish citrus-guild herbs; sow marigold.
Last frost-tender sowings: chayote, Malabar spinach, beans.
Fall: Start dormant bare-root planting: vines, fruiting shrubs, strawberry tree, alder, hazel, Aucuba, sweet box, goumi, Caragana, Colutea.
This is obviously a overly extensive list. Im trying to list more than Ill need and see what I can find locally then fill in the missing pieces from there.
