Can asparagus grow too tall?
Overgrown Asparagus Isn’t “Bolting” Its culinary value is just about nil, and you’ll be weakening the plant. The oversized, fern-like growth of the mature asparagus plant is how the plant photosynthesizes, producing nutrients to be stored in the crown as fuel for the next year’s (or decade’s) growth and production.
Should you cut tall asparagus?

What happens if I don’t harvest my asparagus?
Once the Asparagus plant spears pop open, they’ll become tall, ferny plants. This ferny growth collects energy from the sun, which is stored in the roots. Along with the ferny growth, female plants produce red seeds. These seeds drop to the ground and become new plants if not removed.
Does asparagus spread on its own?
Yes, asparagus plants will spread as they grow. From humble beginnings (seeds or small crowns), asparagus plants can grow quite tall and wide. Asparagus spears may start off small, but they can grow several feet tall! The roots of a mature asparagus plant can spread out 6 feet (1.8 meters) underground.

Better to prop them up. They’ll never do well if you cut them down. I agree with LTilton – from what I have read, they should not be cut back until they have dried.
Why is my asparagus so big?
Each new asparagus spear grows from a bud that forms on the crown. There are never two spears that grow from the same bud, so as the asparagus plant ages (and as long as the underground crown is not damaged from harvesting, insects or diseases), the crown grows larger and larger as more buds are created.
What do you do with overgrown asparagus?
Other Autumn Asparagus Care Once you have cut the asparagus back, add several inches (10 cm.) of mulch to your asparagus bed. This will help to smother the weeds in the bed and will help fertilize the bed for next year. Compost or well-rotted manure makes an excellent mulch for asparagus in autumn.

However, it is generally recommended that the dead foliage be allowed to stand over winter. The dead debris will catch and hold snow. Snow cover helps protect the asparagus crowns from freeze damage.
How do you make asparagus fern bushy?
Take a sharp pair of clean scissors and make a snip where you would like the stem to end. You can do this with all of the elongated stems given that they don’t make up over half the plant and then place your asparagus fern in a brighter spot and your plant should start to grow bushier rather than leggier.
