I hear 'ya.' But, wow, congrats on getting a grafted 'Miami' soursop, you have me wondering how come you chose that one over the 'Homestead,' just curious. If I remember correctly, it'll set fruit in one year.
BTW, someone, above, said something to the effect that if someone believes that there could be more fruit on a 'SourSop' tree than leaves, that he/she has some ice to sell in the N. Pole. Then, I suggest that person can keep the ice, because it is common knowledge that in some fruit trees like hogplum/ciruela, annona and yes, SourSop, this is a common occurrence since they drop all/most of their leaves every year. And, the tree can be full of developed fruit before the leaves start to show or are very small size leaves in comparison to fruit size. Therefore, the TT statement that a SourSop can have more fruit on the tree than leaves is nothing to get all worked up about because it is a common occurrence.
