Perennial Category Growing Guide

Depth to Plant Seeds: 1/4"
Plant Spacing: 24"
Row Spacing: 24"
Watering: Requires heavy watering.
Special Considerations: It can be tricky to grow artichokes from seeds, so I grow from starts purchased at the nursery. Artichokes can be difficult to grow outside of California. Artichokes are a member of the sunflower family. If grown in California, artichokes grow well as a perennial.

Depth to Plant Seeds/Crowns: Seeds - 3/4". Crowns (heirloom, open-pollinated varieties) - 12"
Plant Spacing: 18"
Row Spacing: 18"
Watering: Requires heavy watering.
Special Considerations: Asparagus can be grown from seeds or crowns. Asparagus is grown as a perennial and can grow for 20 years. If growing from crowns, don't harvest any asparagus the first year, harvest lightly the second year, and normally the third year (everything is a year later if growing from seeds - don't harvest the first two years).

Depth to plant Root Cuttings: 4" (dig down 6" and then lay horseradish on the side of the hole with the bud end towards the sky. Cover (horseradish should be under 2" of soil).
Plant Spacing: 12"-18"
Watering: Doesn't need a lot of water, but water regularly.
Special Considerations: Do not plant horseradish in the garden! Every little piece of horseradish root can become a new plant. Instead, plant it in a pot. You can bury the pot if you want it planted at soil level. Don't harvest the first year. The second year, when harvesting, plant some of the cuttings for future years. Horseradish is a member of the cabbage family.

Depth to Plant Root Cuttings: 1"-3"
Plant Spacing: 36"
Row Spacing: 36"
Watering: Water regularly and evenly.
Special Considerations: Do not harvest any the first year. The second year, harvest lightly, and the third year harvest normally. If your rhubarb bed becomes overcrowded, cut out half of each plant and plant the removed half elsewhere or give it away.
