Growing Catnip in Zone 7B

Catnip is more than a cat toy — it’s a useful companion plant that repels aphids, squash bugs, and flea beetles, while also making a calming herbal tea.

Zone 7B enjoys a long growing season. You can often get two plantings of cool-season crops (spring and fall).

Top Growing Tips

  • Protect young plants from cats until established — use wire cloches
  • Perennial in zones 3-9; spreads by runners and self-seeding
  • Harvest before or at early flowering for peak essential oil content
  • Dry leaves for tea or sachets; fresh or dried attracts cats equally
  • Cut back hard after flowering to promote a second flush of growth

Companion Planting

Good companions: squash, beans, brassicas (repels aphids and flea beetles)

Avoid planting near: Keep away from walkways where cats will repeatedly disturb plants

Harvest Timeline

Harvest anytime; best before flowering; dry at low temperature

About Zone 7B

USDA Hardiness Zone 7B has an average last spring frost around Mar 28 and first fall frost around Nov 3. 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 7B Climate Notes

Zone 7B has mild winters that allow some crops to grow year-round in protected conditions. Plant cool-season crops in late summer for fall and winter harvests. The long warm season supports excellent production of heat-loving crops like peppers and eggplant.
