Asparagus Jersey Knight Hybrid - All-male strain - Top-size green spears with feisty purple tips! The spears are a full 5/8-inch in diameter.  They are bright green with deep purple tips and bracts. Stunning on the dinner plate, they're one of the easiest varieties to grow, thanks to terrific vigor that makes these plants come back stronger every year!

The yield you can expect from Jersey Knight is 2 to 4 times greater than older strains. Highly Rust-resistant and tolerant of Fusarium, Crown and Rust Rot.  Jersey Knight is the one you want for years of reliable performance!

Harvest: The second spring, there will be a few spears but don’t pick them yet.  The third spring, it is okay to harvest some finger-sized spears for 2 to 4 weeks.  After the third spring, pick all the finger-sized spears that you want for 6 to 8 weeks.  Once the weather turns hot, the spears will come up thin and spindly and should be left to grow foliage.  Harvest the spears that are ⅜” in diameter and 6 to 8 inches tall.  The tips should be tight, not open and loose. There are two methods for harvesting asparagus.  Some people snap the spear off, often where the spear starts to become tender.  Others cut the spears just below the surface of the soil for longer spears.  Stop harvesting when stalks are less than 3/8” thick.

 

Quick Facts

Plant Care

Sun: Full Sun
Water: Average
Soil: Well drained, pH balance of 6.5-7.5

Plant in the spring.  Choose an out-of-the-way spot in your garden where the ferny foliage that grows from the spears won’t be in the way.  Asparagus needs at least 6 to 8 hours of sun a day. Check the pH of your soil.  Asparagus tends to like sweeter soil than many other veggies and likes soil with a pH balance of 6.5-7.5.  Add lime if necessary.  In early spring, dig a trench 16-inches deep and ten inches wide.  Add 2 to 3 inches of compost or manure and work into the soil at the bottom.  Add a dusting of 10-10-10 fertilizer. 

Asparagus is a heavy feeder and needs regular fertilizing with well rotted manure, compost or a well balanced synthetic fertilizer worked in the top surface of the soil. Use straw mulch to control weeds and hold moisture.

Asparagus rust diseases can be avoided by planting with rust and disease resistant varieties.  Prepare your asparagus bed in the fall before planting.  This will allow the lime and nutrients to work into the soil and will allow you to get your asparagus plants in the ground very early in the spring.  They love organic matter like compost or aged manure:  the more the better!

In early spring, cut or snap asparagus spears when they are 6-8" high, before the heads separate.
