In this episode, we discuss:
How asparagus plants grow
How and when to plant asparagus
Selecting a site for your asparagus plants
Harvesting and fertilization
When is the best time to plant asparagus crowns?
Asparagus can be planted up to 6 weeks before your last frost date, but anytime in the spring is fine!
In what type of growing conditions does asparagus thrive?
Asparagus need full sun, well drained soil, and a well prepared dedicated space!
How do I plant asparagus crowns?
Dig a 8 in. deep trench, spread out roots of the crown on the bottom of the trench. Space each crown 18 in. apart. Cover with 3-4 in. of garden soil and continue to fill in with soil every two weeks, like you would with potatoes, until the trench is full.
Should I fertilize my asparagus?
Fertilize asparagus plants after you've finished harvesting for the season. The added nutrients will feed the flowering fronds and encourage them to thrive, photosynthesis, and replenish the energy stored in the underground rhizomes.
