Here are my grafted jaboticabas on a sabara as rootstock which i got from adam almost 2 years ago now...
All of these i planted in a 15 gal using 100% dirt..
Coronata - restinga
Grimal
3in1 (aureana, restinga,grimal)
Possible grimal swelling buds on 3in1..
Sabara i got from lynn
As time passes by, from dirt it became porous soil after infusing them with compost tea, organic ferts, coffee grounds &leftover fruits/ veggie...
I have more red jabos, esalq,escarlate,blue,yellow jabo not in photos but r growing well with initial dirt.
They have experienced 122f & 27f with no problems.
