How to grow Asparagus
in the UK
Sow March to April, plant out May, harvest April to June. About 730 days from seed to plate.
Now then, asparagus. It's a proper luxury, isn't it? Takes a bit of patience, mind, but once it's in, you've got spears year after year, proper chuffed you'll be. It's a perennial, so find it a good spot on the plot and it'll be your friend for decades.
Sowing
You don't usually sow asparagus from seed straight off, because it takes ages, like two years before you get owt. Most folks, myself included, buy one-year-old crowns in spring, usually March or April up here. You want to dig a trench about 20-25 cm deep, make a little mound of soil in the middle, and spread the roots of your crown over it. Space 'em about 30-45 cm apart, then cover 'em gently. It's a bit of a job but it's worth it for the long run.
Growing on
Once those crowns are in, the main thing is patience, to be honest. You'll see ferny growth appearing, and that's what you want. No harvesting for the first two years, you hear? It feels wrong, I know, but you need to let those plants establish a proper root system. Keep the bed weed-free around them, and they'll grow into big, ferny plants ready for future harvests. Think of it as an investment.
Looking after it
Asparagus likes a good drink, especially when it's settling in and during dry spells. Give it a proper mulch of well-rotted compost or manure each spring, that'll keep the weeds down and feed the hungry roots. Keeping it tidy and well-fed is the key to a long-lived, productive bed. Some folks plant tomatoes, parsley, or basil nearby, apparently they're good companions.
What goes wrong
Now, the usual suspects can cause bother, like slugs enjoying the tender new spears, especially when they're just popping up. Keep an eye out for the asparagus beetle too; those little stripy blighters can munch through the ferny growth. Violet root rot is a nasty one, but less common if you've got good drainage. Just keep an eye on things and deal with 'em as you spot 'em.
Harvest
Right, the best bit! From year three onwards, you can start harvesting. Cut the spears when they're about 15-20 cm tall, just below ground level with a sharp knife. Only harvest for 6-8 weeks, stopping by mid-June up here, to let the plants store energy. Like I say, it's best eaten the same day. For a glut, you can stand it in water in the fridge for a couple of days, or blanch and freeze it.

If you're planting crowns, make sure you really give the soil in the trench a good dose of well-rotted manure before you put 'em in. It's a long-term crop, so that initial feed makes all the difference.
