'Cossack Pineapple' Ground Cherry problems — and how to fix them
'Cossack Pineapple' Ground Cherry (Physalis pruinosa 'Cossack Pineapple') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Knowing when fruit is ripe
Berries are sweet only when fully ripe; harvest the husked fruit after it naturally drops to the ground and the husk turns papery tan.
Self-seeding spread
Dropped fruit reseeds freely and can pop up as volunteers next season; clear fallen husks if you want to limit spread.
Sprawling habit
Plants flop wide and fruit sits on soil; mulch beneath and use a low cage or let them sprawl over clean straw to keep berries tidy.
Slow to ripen in cool summers
Needs a long warm season; start early indoors and grow in the warmest, sunniest spot, or under cover in cool-climate gardens.
