Rhubarb is a popular perennial vegetable that thrives in many gardens across Zone 3. Proper care during May is essential to ensure a healthy harvest throughout the season. This guide provides tips on harvesting and storing rhubarb to maximize its flavor and longevity.
Preparing Rhubarb for the Growing Season
In Zone 3, May marks the beginning of active growth for rhubarb. Before harvesting, ensure the plants are well-established from the previous year. Remove any dead or damaged stalks and clear weeds around the crowns to reduce competition for nutrients.
Harvesting Rhubarb in May
Rhubarb is best harvested when the stalks are at least 12 inches long and have a deep red or green color, depending on the variety. In Zone 3, start harvesting cautiously in May, focusing on the largest, healthiest stalks. Always use clean, sharp scissors or knives to cut stalks at the base.
Avoid harvesting more than one-third of the plant’s stalks at a time to prevent stress and promote vigorous growth. Do not harvest stalks in the first year after planting, allowing the plant to establish a strong root system.
Storing Rhubarb
After harvesting, rhubarb can be stored to extend its usability. Rinse stalks gently with cold water and pat dry. Wrap stalks in plastic wrap or place them in a perforated plastic bag to maintain humidity.
Store rhubarb in the refrigerator’s crisper drawer for up to one week. For longer storage, consider freezing. Chop stalks into 1-inch pieces, blanch in boiling water for 30 seconds, then cool quickly in ice water. Drain thoroughly and pack into airtight containers or freezer bags.
Additional Tips for Zone 3 Gardeners
- Apply a balanced fertilizer in early spring to promote healthy growth.
- Ensure the plant receives adequate water, especially during dry spells.
- Mulch around the plant to conserve moisture and suppress weeds.
- Watch for pests such as aphids and treat promptly.
- Rotate rhubarb beds every 3-4 years to prevent disease buildup.
Following these guidelines will help you enjoy a bountiful rhubarb harvest throughout the season. Happy gardening!
