Hi Sarah, no, I have not tasted a Black Madeira. Being 1/2 Portuguese myself, I sought out varieties from there as well as Madeira, where my grandfather was from. My BM cutting came from an East Coast member, 17 months ago. Lucky I did not know at the time how fussy this variety can be, it just took off for me. I only had Abebereira ripen last year, of my Portuguese varieties, and it is very good. Several others I should get this year. I'll let you know how the Black Madeira compares with Grise de St Jean, or maybe you'll get to discover that for yourself:)
Igor, hello. I do not feed them often. I believe my soil mix provides slowly released, long lasting nutrients. As I've stated before, equal parts compost and organic potting soil, some oyster shell, and rock phosphate. My compost has a lot of horse manure, which supplies long lasting nitrogen. As the plants leaf out in Spring, I apply fish meal, and every 3rd or 4th week, I water with fish emulsion. That's about it.
Rafael and John, thanks, glad you enjoyed the photos. I will share when it's tasting time.
