Dangling particple/gerund

Hello Paco san

I fear we would then have a dangling lacuna:

1. 'Now' = the time of the problem, which is 'after':
2. {the void}, i.e. the time which is after the buying, but before the 'after'.
3. The buying of the apple tree.

We might close the gap by saying 'after my buying an apple tree', but then the clause would seem to require a verb to qualify; whereas all we have is a meagre predicate.

And if we say 'after buying an apple tree', for a wild moment 'the only problem' appears to be its subject, till once again we find ourselves embarrassingly dangling.

Tricky.
