How do you make asparagus more productive?
You can top-dress with a balanced organic fertilizer, or scatter another inch of rich, weed-free compost over the decomposing mulch. Do NOT cut down the remaining ferns in summer or you will ruin your asparagus bed. Allow the ferns to grow and mature; this replenishes the nutrients for next year’s spear production.
How do you rejuvenate an asparagus bed?
Use an organic fertilizer in the early spring, before spears begin to emerge, to give plants a boost. Apply nitrogen after harvesting is finished to encourage foliage growth. You can also fill in the gaps between old plants with some young, fresh roots. You will end up with a nice, solid bed in a few years.
How do you control weeds in asparagus bed?
Glyphosate is systemic and works best at controlling perennial weeds. It can be broadcast over the entire planting area in early spring before new asparagus grown emerges or after the last harvest. Snap all spears 1/2 inch below the soil line, so no spears are above ground, then overspray the planting area.
Are grass clippings good for asparagus?
Asparagus loves a deep, loose mulch. Although pine needles may work for this purpose, they make the soil more acidic as they decay. Asparagus grows best in alkaline soil, so I’d suggest you use shredded grass clippings, decaying straw, well-rotted sawdust or compost as the mulching material.
How do you prepare an asparagus bed for spring?

Are eggshells good for asparagus?

Should you let asparagus flower?
Ferning out in asparagus is actually a good thing, as it indicates that photosynthesis is being promoted, therefore, nutrition production and absorption increases. During the ferning process, the majority of the energy produced is stored in the roots to facilitate new growth the next year.
When should I trim my asparagus?

Should asparagus fertilize?
Generally, it is not necessary to apply fertilizer for an established asparagus crop until after harvest. In fact, delaying fertilization until after harvest can reduce early weed growth. For sandy coarse-textured soils, however, 20-25 lbs N/acre in the spring may be beneficial for spear development.
