Grown in USDA zones 3-8, a well cared for asparagus patch will produce for 15-25 years! One of the first spring vegetables to be harvested in the garden, Purple Passion asparagus can be harvested for up to 8 weeks before the plants start to go to seed. Compared to other asparagus varieties, they emerge later in the spring, which protects them better from frost damage. A bundle of 25 crowns will plant a 4â€™ x 12â€™ bed and once established and well tended can yield 12 to 15 lbs of amazing asparagus. This variety is resistant to rust and fusarium, and is tolerant of root and crown rot.
Dig a trench 8â€ deep. Spread asparagus crowns over the soil and add a few inches of soil. Once they begin to grow add more soil until the trench is filled. If your soil is clay, you will need to add lots of mulch. Space 12 inches apart is recommended but many people will space as close as 6-8â€ apart for more compact spaces. Once Plants have gone dormant in winter, mow over with a lawn mower. In order to establish asparagus plants, you should not pick any spears the first year. Expect a light harvest in the 2nd year, a larger harvest the 3rd year, and a full harvest in the following years.
Even if you already have a patch of any green variety of asparagus, Purple passion is sure to become your favorite.
