Asparagus 'Connover's Colossal'

Asparagus spears are the edible part of the plant, and are the new fat shoots that emerge in Spring. If left, the shoots will produce the fern foliage, and the female plants will produce seed. Asparagus 'Connover's Colossal' received an RHS AGM. Has exceptional yield for a non-hybrid. The spears are bright green with purple tips

Planting

From Early Spring TO Early Spring

Plant asparagus crowns in Spring. The bed for asparagus needs to be permanent, so choose your site carefully - asparagus don't start producing edible spears for at least two years after planting, but after that can grow and produce for many years. Weed the patch carefully, and dig a trench 12" wide and 8" deep. Add 4" of manure or compost.Make a ridge approx. 4" high along the middle of the trench, and spread the roots of the crown over this ridge, spacing the plants 18" apart. Cover the roots with soil up to the level where the buds are just visible. Water in, then mulch to keep weed growth down
