Bay Laurel in Zone 4A — Great Plains

Bay Laurel brings a touch of Mediterranean flavor to your Great Plains garden. The aromatic leaves are a culinary staple, and the plant itself provides beautiful structure. Plus, its drought tolerance means it can handle our variable rainfall better than some other herbs.

Our region is known for extreme weather, from temperature swings to hail. But with a little planning and the right timing, Bay Laurel can thrive here. Our relatively short 138-day growing season just means we need to give it a head start.

Starting Bay Laurel from seed indoors is possible, but be warned: it's a slow process. If you're up for the challenge, begin in late February through mid March, roughly 12 weeks before you intend to transplant outdoors.

Use seed trays with a good seed-starting mix, and keep them consistently warm – a heat mat helps. Provide ample light, either from a sunny window or a grow light, and water from the bottom to avoid damping off. Remember that our spring weather can be variable here on the Plains, so be prepared to adjust your setup as needed.

Transplant your Bay Laurel seedling outdoors in late May after the risk of frost has passed. Before planting, harden off your seedling by gradually exposing it to outdoor conditions for about a week.

Space plants 48-96 inches apart, as they can grow into substantial shrubs or small trees. Honestly, though, given our short growing season, you're better off buying an established plant. It takes years for a seedling to reach a usable size. Keep an eye on the weather forecast around transplant time; a late cold snap can still happen.

Once established, Bay Laurel is moderately drought-tolerant, which is a real asset in the Great Plains. However, young plants and those in containers need more regular watering. The key is to find the right balance, especially with our variable rainfall.

During the heat of summer, aim to water deeply about once a week, providing roughly an inch of water. Use the "finger test" – stick your finger about two inches into the soil. If it feels dry, it's time to water. Water at the base of the plant to avoid wetting the foliage, which can help prevent fungal issues in our low-to-moderate humidity.

Signs of underwatering include wilting leaves and slow growth. Overwatering can lead to yellowing leaves and root rot. A layer of mulch around the base of the plant helps retain moisture and regulate soil temperature, which is particularly helpful during our extreme temperature swings.

Bay Laurel requires minimal pruning. Focus on maintaining its shape and size. You can heavily prune Bay Laurel without causing damage, so don't be afraid to cut back branches that are getting too long or unruly.

The best time to prune is in spring, after the worst of the winter weather has passed. As the first frost approaches in late September, you can give your plant a light trim to remove any dead or damaged branches, but avoid heavy pruning at this time.

You can begin harvesting Bay Laurel leaves in late May through early October. Mature, dark green leaves have the strongest flavor. Harvest individual leaves as needed throughout the growing season. This continuous harvest won't hurt the plant.

To harvest, simply snip off the leaves with scissors or pruning shears. You can use the leaves fresh or dry them for later use. As the first frost approaches in late September, harvest any remaining mature leaves to dry and store for winter.

Here are some common problems you might encounter with Bay Laurel in the Great Plains:

Scale Insects

• What it looks like: Small, brown, shell-like bumps on the stems and leaves.
• What causes it: Scale insects thrive in warm, dry conditions. Our hot summers can create ideal conditions for them.
• How to fix/prevent it: Inspect your plants regularly. Remove scale insects by hand or with a cotton swab dipped in rubbing alcohol. Horticultural oil can also be effective.

Cold Damage

• What it looks like: Brown, wilted leaves, especially after a cold snap.
• What causes it: Bay Laurel is only semi-hardy and can be damaged by temperatures below zone 8. Our extreme temperature swings can be particularly hard on them.
• How to fix/prevent it: Container-grown plants can be brought indoors for the winter. For plants in the ground, provide winter protection, such as wrapping them in burlap or creating a windbreak.

Slow Growth

• What it looks like: Minimal growth from year to year.
• What causes it: Bay Laurel is naturally a slow grower, and our short growing season can exacerbate this.
• How to fix/prevent it: Ensure your plant is in well-draining soil and receives adequate sunlight. Fertilize regularly with a balanced fertilizer to encourage growth.

Great Plains Specific Challenges: Our hot heat combined with our variable rainfall can stress Bay Laurel. Consistent watering during dry spells is essential. Wind protection is also crucial, as strong winds can damage leaves and dry out the soil.

Good companion plants for Bay Laurel in the Great Plains include:

• Green Beans: Beans fix nitrogen in the soil, which can benefit Bay Laurel.
• Rosemary: Rosemary is drought-tolerant and shares similar growing requirements with Bay Laurel.
• Sage: Sage repels many common pests, which can help protect Bay Laurel.

I'd avoid planting Bay Laurel near anything that requires consistently moist soil, as that could lead to overwatering problems for the Bay Laurel.
