How do you keep asparagus fern from spreading?
Mow It Repeatedly First, it prevents the plant from producing berries and seeds, thus helping to halt its spread. Second, repeatedly cutting it to the ground forces the plant to expend its energy on regrowing; over time this can starve the plant’s underground tubers and kill it.
Are asparagus ferns invasive?
Asparagus fern (Asparagus densiflorus) is a highly invasive, shade-tolerant perennial plant. Once established, they are challenging to control due to an extensive root structure and the ability to regrow from small parts of roots.
How do you keep asparagus ferns small?
Mist the plant daily and provide a nearby pebble tray to keep the tiny leaves from turning brown and dropping. The fern may dry out to the point it appears dead, however, outdoor springtime temperatures generally revive them. Keep the plant well watered in all situations and repot every few years.
How do you get rid of climbing asparagus?
What can I do to get rid of it?
- Dig out tubers. Dispose of at a refuse transfer station, burn or bury.
- Spray (spring-early summer only): glyphosate (20ml/L). Do not add penetrant when spraying against tree trunks.
- Spray (autumn and winter in frost free areas and on healthy growth): glyphosate (10ml/L).

Can I cut back asparagus ferns?
Asparagus Fern Pruning Climbing asparagus ferns can be lightly trimmed without issue, so just cut back the unwanted growth to the nearest branching stem, although North Carolina State University Cooperative Extension recommends cutting the fronds all the way back to the root whenever possible.
What do you do with overgrown asparagus?

Does Roundup work on asparagus fern?
Spray the asparagus fern with a glyphosate-based systemic herbicide such as Roundup. This method is ideal for large fern populations. Mist all of the asparagus fern’s fronds with the herbicide. For best results, spray during a dry period.

Should asparagus plants be cut back?
