Growing Valerian in Zone 6A
Valerian is a tall, fragrant perennial grown for its roots, which are used in calming supplements. The flowers attract beneficial insects in droves.
Zone 6A has a moderate growing season. Most crops do well here with proper timing around frost dates.
Top Growing Tips
- Grows to 4-5 feet tall — plant toward back of borders
- Flowers attract cats similarly to catnip — protect if needed
- Roots are harvested in fall of the second year for maximum potency
- Attracts earthworms to the surrounding soil — excellent for soil health
- Self-seeds freely; deadhead to control spread
Companion Planting
Good companions: most vegetables (beneficial insect attractor), lettuce, peas
Avoid planting near: Too-close planting where it will shade shorter crops
Harvest Timeline
Harvest roots in fall of year 2+; harvest flowers anytime for dried arrangements
About Zone 6A
USDA Hardiness Zone 6A has an average last spring frost around Apr 21 and first fall frost around Oct 15. All planting dates above are calculated from these frost dates. Your specific location may vary — check with your local extension office for the most accurate dates.
Soil Preparation
Good soil preparation is the foundation of a productive garden. Work in 2-3 inches of compost before planting to improve drainage, water retention, and nutrient availability. A soil pH between 6.0 and 7.0 suits most vegetables. Test your soil every few years and amend as needed with lime (to raise pH) or sulfur (to lower pH).
Watering Guide
Consistent moisture is essential for healthy plant development. Most vegetables need 1-1.5 inches of water per week. Drip irrigation or soaker hoses deliver water directly to roots and reduce foliar disease. Water deeply and less frequently to encourage deep root growth. Mulching with 2-3 inches of straw or wood chips dramatically reduces water needs and suppresses weeds.
Zone 6A Climate Notes
Zone 6A is an excellent gardening zone with good balance between cool and warm seasons. Most vegetables perform well here. Extend the season with cold frames in fall and row covers in early spring. Two rounds of cool-season crops are often possible.
