2. Late Summer: Light Maintenance Pruning

If you missed the spring window, late summer (around August) is when to prune asparagus fern for lighter touch-ups.
 
During this time, you’re not cutting the whole plant down, just removing individual fronds that look tired, brown, or damaged.
 
This is also when to prune asparagus fern if you want to control its size before it gets too unruly inside your home or garden bed.
 
Light pruning in late summer won’t stimulate a lot of new growth, which is good because you don’t want tender shoots getting hit by early fall frosts.
 
So keep late summer as your secondary answer for when to prune asparagus fern.
 

3. What About Winter? A Warning

So if you’re tempted to tidy up in December, resist the urge.
 
Winter is simply not when to prune asparagus fern if you care about its long-term health.
 

Signs That Tell You It’s Time to Prune Asparagus Fern

Beyond the season, your plant will give you clear visual clues that it’s time to act.
