Growing perennial herbs in zone 2 is hard – there really is no sugarcoating it. The region’s severe climate is characterized by very cold winters, short growing seasons, and the possibility of poor soil quality.
The survival of perennial herbs in this inhospitable environment is not guaranteed, as only a limited number of cold-hardy species can endure the low temperatures and adverse conditions. Gardeners in zone 2 must carefully consider the specific needs of each herb, provide adequate care, and take precautions to improve the chances of success.
This may include employing cold frames, applying mulch, or creating windbreaks to protect the plants from the elements. Despite these efforts, it is essential to understand that some herbs may still struggle to thrive as perennials in zone 2 due to the extreme climatic conditions.
Grow these 8 perennial herbs in zone 2
Zone 2 is characterized by very cold winters, with minimum temperatures ranging from -40 to -50 degrees Fahrenheit (-40 to -45 degrees Celsius). It can be challenging to grow plants in this harsh environment, but there are a few cold-hardy perennial herbs that may survive in zone 2:
- Chives (Allium schoenoprasum): These cold-hardy perennial herbs can withstand low temperatures and are suitable for growing in zone 2.
- Siberian chives (Allium nutans): Like common chives, Siberian chives are also well-suited for colder climates.
- Lovage (Levisticum officinale): Lovage can tolerate cold temperatures and may survive in zone 2 with proper care.
- Mint (Mentha spp.): Some species of mint, like wild mint (Mentha arvensis) and peppermint (Mentha x piperita), can tolerate cold conditions and may grow in zone 2.
- Oregano (Origanum vulgare): Cold-hardy varieties of oregano, such as the cultivar ‘Nana,’ can tolerate low temperatures and grow in zone 2.
- Sorrel (Rumex acetosa): Sorrel is a cold-hardy perennial herb that can grow in zone 2.
- Thyme (Thymus spp.): Some species and cultivars of thyme, like Arctic thyme (Thymus praecox ssp. arcticus) and creeping thyme (Thymus serpyllum), can tolerate cold conditions and grow in zone 2.
- Yarrow (Achillea millefolium): Yarrow is a hardy perennial herb that can withstand the cold temperatures of zone 2.
Success growing these plants in zone 2 will depend on various factors, including microclimates, soil conditions, and proper care. You may need to provide additional protection, such as using cold frames, mulching, or windbreaks, to help ensure their survival in such a harsh environment.
Tips for growing herbs in zone 2
Growing perennial herbs in zone 2 can be challenging, but with proper care and consideration, it is possible to cultivate a selection of cold-hardy herbs. Here are some tips to help you succeed:
- Choose cold-hardy varieties: Opt for perennial herbs that are known for their cold tolerance and ability to withstand the harsh conditions in zone 2.
- Start indoors: To give your herbs a head start, sow seeds indoors several weeks before the last expected frost. Transplant seedlings outdoors once the soil has warmed up and the risk of frost has passed.
- Microclimates: Utilize microclimates in your garden, such as planting near structures or large rocks, which can help protect plants from harsh winds and retain heat.
- Cold protection: Employ cold frames, row covers, or cloches to extend the growing season and protect your herbs from frost and freezing temperatures.
- Mulching: Apply a thick layer of mulch around the base of your plants to help insulate the soil, retain moisture, and protect the roots from extreme temperatures.
- Windbreaks: Create windbreaks using hedges, fences, or walls to shield your herbs from cold, drying winds.
- Proper drainage: Ensure your planting site has well-draining soil to prevent root rot and other issues caused by waterlogged conditions.
- Amend the soil: Improve the quality of your soil by adding organic matter, such as compost or aged manure, to provide essential nutrients and improve soil structure.
- Regular pruning: Prune your herbs regularly to encourage bushy growth and prevent legginess. Remove any dead or damaged growth to maintain plant health.
- Overwintering: For more tender perennial herbs, consider digging them up and bringing them indoors in containers to overwinter. Place them in a cool, bright location and return them to the garden in spring.
By following these tips, you can maximize your chances of successfully growing perennial herbs in the challenging climate of zone 2.
