Why Michigan is Perfect for Lavender (and its Challenges)
Michigan’s climate, with its distinct four seasons, offers some surprising advantages for lavender cultivation. Lavender thrives in full sun and well-draining conditions, which we can certainly provide.
However, we also face specific challenges:
- Cold Winters: Our USDA Hardiness Zones range from 4 to 6, meaning we need varieties that can withstand freezing temperatures and prolonged snow cover.
- Wet Springs & Humidity: Lavender dislikes “wet feet” and high humidity, which can lead to root rot and fungal issues.
- Heavy Clay Soils: Many areas in Michigan have naturally heavy clay soils, which retain too much moisture for lavender’s liking.
Understanding these factors is the first step to success. The good news? With a few strategic adjustments, you can absolutely overcome these hurdles and enjoy a thriving lavender garden.
Choosing the Right Lavender Varieties for Michigan’s Climate
The key to success in Michigan starts with selecting the right type of lavender. Not all lavenders are created equal, especially when it comes to cold hardiness.
Hardy English Lavender (Lavandula angustifolia)
This is your go-to choice for Michigan gardens. English lavender varieties are the most cold-hardy, typically surviving down to USDA Zone 5, and often Zone 4 with proper care.
- ‘Munstead’: A classic, compact variety with silvery foliage and abundant, fragrant purple flowers. It’s incredibly resilient and perfect for Michigan.
- ‘Hidcote’: Similar to ‘Munstead’ but with slightly darker purple flowers and a more upright growth habit. Another excellent choice for its hardiness.
- ‘Lavender Lady’: Known for blooming in its first year from seed, making it a favorite for those eager for quick results.
- ‘Betty’s Blue’: Offers striking deep violet-blue flowers and a lovely aroma.
Hardy Lavender Hybrids (Lavandula x intermedia)
These are crosses between English and Spike lavenders, often called Lavandins. While generally less hardy than true English lavenders, some newer varieties show promising resilience in Michigan’s Zone 5 and even protected Zone 4 spots.
- ‘Phenomenal’: A relatively new hybrid known for its exceptional vigor, disease resistance, and cold hardiness (down to Zone 4). It has long flower spikes and a strong fragrance.
- ‘Grosso’: A popular lavandin, often used for essential oil production. It’s fairly hardy, but ‘Phenomenal’ often outperforms it in colder Michigan zones.
Avoid French (Lavandula stoechas) and Spanish (Lavandula dentata) lavenders. While beautiful, they are simply not hardy enough to survive Michigan winters outdoors, even with protection.
Site Selection and Soil Preparation for Thriving Lavender
Lavender is not a demanding plant once established, but it is particular about its initial home. Getting the site right is crucial.
Sunlight is Non-Negotiable
Your lavender plants need at least six to eight hours of direct sunlight every day. More is always better! Choose the sunniest spot in your garden, ideally one that also offers good air circulation.
The Importance of Well-Draining Soil
This is arguably the most critical factor for success when you how to grow lavender in Michigan. Lavender hates soggy roots. If your soil is heavy clay, you must amend it significantly or opt for raised beds.
Testing Your Soil Drainage
Dig a hole about 12 inches deep and wide. Fill it with water. If the water drains within 10-15 minutes, your drainage is good. If it takes an hour or more, you have poor drainage.
Amending Clay Soil
To improve drainage, mix in copious amounts of:
- Coarse Sand or Grit: Horticultural sand, not play sand, improves soil texture.
- Perlite: Lightweight and excellent for aeration.
- Small Gravel: Helps create pockets for drainage.
- Compost: While compost holds some moisture, it also improves overall soil structure and aeration. Use it judiciously, focusing more on grit for drainage.
Aim for a gritty, sandy loam texture. Many Michigan gardeners find success by creating a large mound or a raised bed specifically for their lavender, filling it with a custom-drained soil mix.
Soil pH Matters
Lavender prefers a slightly alkaline to neutral pH (around 6.7 to 7.3). Michigan soils can sometimes be acidic. A simple soil test kit will tell you your pH. If your soil is too acidic, you can raise the pH by adding garden lime (dolomitic lime is good as it also adds magnesium).
Planting Your Lavender for Success in Michigan
Once you’ve chosen your varieties and prepared your site, it’s time to plant!
When to Plant
The best time to plant lavender in Michigan is in late spring after the danger of the last frost has passed, usually late May to early June. This gives the plants ample time to establish their root systems before the stress of summer heat and, crucially, before winter sets in.
Step-by-Step Planting Guide
- Dig the Hole: Dig a hole twice as wide as your lavender plant’s root ball and just as deep.
- Loosen Roots: Gently tease apart any circling roots on your plant. This encourages them to spread into the new soil.
- Plant High: Plant your lavender so that the top of the root ball is slightly above the surrounding soil level. This is another trick to prevent “wet feet.”
- Backfill: Fill the hole with your amended soil, gently firming it around the base of the plant.
- Water Sparingly: Give the newly planted lavender a light watering to settle the soil. Avoid overwatering.
- Spacing: Provide adequate spacing between plants—18 to 24 inches for English varieties, and up to 3 feet for larger hybrids like ‘Phenomenal’. Good air circulation is vital to prevent fungal diseases.
Consider planting on a slight mound or in a raised bed if your natural soil drainage is poor, even after amending.
Essential Care and Maintenance for Lavender in Michigan
After planting, consistent care will ensure your lavender thrives and blooms beautifully year after year.
Watering Wisdom
Established lavender is drought-tolerant. In fact, overwatering is the number one killer of lavender plants. Water new plants once or twice a week during their first growing season, allowing the soil to dry out completely between waterings.
Once established (after a year), you’ll rarely need to water, except during prolonged dry spells or extreme heat. Always check the soil moisture several inches deep before watering.
Fertilization: Less is More
Lavender actually prefers lean soil. Avoid fertilizing, especially with high-nitrogen fertilizers, which promote leafy growth at the expense of flowers and can make the plant less hardy. If your soil is truly poor, a light application of bone meal or a balanced, slow-release granular fertilizer in early spring might be beneficial, but it’s often unnecessary.
Mulching (the Right Way)
Traditional organic mulches like wood chips or shredded bark retain moisture, which is detrimental to lavender. Instead, use a light layer (1-2 inches) of light-colored gravel or crushed stone around the base of your plants. This helps:
- Reflect heat, keeping the crown dry.
- Suppress weeds without holding excess moisture.
- Provide additional drainage.
how to grow lavender in michigan: Overwintering and Pruning for Longevity
These two practices are paramount for ensuring your lavender survives Michigan’s winters and remains vigorous and productive.
Pruning for Health and Shape
Regular pruning keeps your lavender plants from becoming woody and leggy, promoting more blooms and a compact shape.
- First Year: Pinch back new growth tips to encourage branching. After the first flush of flowers, deadhead spent blooms.
- Annual Pruning (Early Spring): This is the most important prune. Once new green growth appears at the base of the plant in early spring (usually April in Michigan), cut back about one-third of the plant’s overall size, focusing on removing old flower stalks and shaping the plant. Aim to leave at least 2-3 sets of leaves on each stem.
- Post-Bloom Pruning (Late Summer): After the main flowering period, you can do a lighter prune to remove spent flower stalks and tidy up the plant. Avoid heavy pruning late in the season, as new growth might not harden off before winter.
Never cut back into the old, woody stems that have no green leaves. This can kill the plant or prevent it from regrowing.
Winter Protection for Michigan Lavender
Even hardy varieties appreciate a little extra care to help them sail through our Michigan winters.
- Good Drainage: This is your best defense against winter kill. If the roots sit in frozen, soggy soil, they will rot.
- Snow Cover: A blanket of snow acts as natural insulation, protecting plants from extreme temperature fluctuations. Don’t remove snow from your lavender beds.
- Air Circulation: Ensure plants aren’t crowded. Good air circulation prevents moisture buildup around the crown.
- Avoid Heavy Mulch: As mentioned, steer clear of organic mulches that trap moisture. If you use gravel mulch, that’s fine.
- Container Lavender: If you’re growing lavender in pots, bring them indoors to an unheated garage, shed, or cool basement. They need a period of dormancy. Reduce watering significantly, just enough to prevent the soil from drying out completely.
With proper site selection, variety choice, and these overwintering strategies, your journey to how to grow lavender in Michigan will be a resounding success.
Common Pests, Diseases, and Troubleshooting
Lavender is generally a resilient plant, but even in Michigan, it can face a few issues.
Pests
Lavender is naturally deer and rabbit resistant due to its strong scent. However, you might occasionally see:
- Aphids: Small, soft-bodied insects that cluster on new growth. A strong spray of water or insecticidal soap can manage them.
- Spittlebugs: You’ll see frothy “spit” on stems, protecting small green insects. They rarely cause significant damage and can be rinsed off.
Diseases
Most diseases are related to too much moisture.
- Root Rot: The most common issue, caused by poorly draining soil and overwatering. Symptoms include wilting, yellowing leaves, and eventual plant death. Prevention through proper soil preparation is key.
- Fungal Leaf Spot: Can occur in humid conditions. Ensure good air circulation and avoid overhead watering. Remove affected foliage.
If you notice issues, assess your watering habits and soil conditions first. Often, a simple adjustment can rectify the problem.
Harvesting and Enjoying Your Michigan Lavender
The reward for all your hard work is a beautiful, fragrant harvest! Knowing when and how to harvest will maximize your enjoyment.
When to Harvest
The ideal time to harvest lavender is when the flower buds have just opened, but before the flowers are fully bloomed. This is when the essential oil content and fragrance are at their peak.
In Michigan, this usually occurs from late June through July, depending on the variety and spring weather.
How to Harvest
- Choose the Time: Harvest in the morning after the dew has dried, but before the heat of the day.
- Use Sharp Shears: Cut the flower stalks with sharp pruning shears, taking long stems. Leave a few inches of green growth on the plant.
- Gather Bundles: Gather stalks into small bundles and secure them with a rubber band or twine.
- Hang to Dry: Hang the bundles upside down in a cool, dark, well-ventilated area. Drying can take 1-3 weeks.
Once dry, you can strip the fragrant buds from the stems for sachets, potpourri, culinary uses (like lavender shortbread or tea), or simply enjoy the dried bundles as decorative elements.
Frequently Asked Questions About Growing Lavender in Michigan
