Michigan’s Great Lakes create microclimates that shift optimal planting times by several weeks across the state. Finding the best time to plant lemon grass in michigan depends on where you live and how you start your plants. This guide will give you clear dates and steps for success.
Lemongrass is a tender perennial that cannot survive Michigan winters outdoors. You must treat it as an annual or overwinter it indoors. The key is to wait until all frost danger has passed before moving plants outside.
Understanding Michigan’s Growing Zones
Michigan spans USDA hardiness zones 4a to 6b. The southern part near Lake Michigan is warmer, while the Upper Peninsula is much colder. This affects your planting calendar.
Zone 5 And 6 Areas
These include most of the Lower Peninsula south of Bay City. You have a longer growing season. The best time to plant lemongrass here is late May to early June.
Zone 4 And Northern Areas
This covers the Upper Peninsula and northern Lower Michigan. You must wait until early to mid-June. Soil temperature is the real deciding factor.
Best Time To Plant Lemon Grass In Michigan
The exact best time to plant lemon grass in michigan is after the last expected frost date for your area. For most of the state, this falls between May 15 and June 10. Soil should be at least 60°F (15°C) for strong root growth.
Check your local frost dates using the Old Farmer’s Almanac or your county extension office. Do not rely on a single date; watch the weather forecast for late cold snaps.
Starting From Seed Indoors
Lemongrass seeds need warmth to germinate. Start them indoors 8 to 10 weeks before your last frost date. Use a heat mat to keep soil at 70°F.
- Fill seed trays with moist seed-starting mix
- Sow seeds 1/4 inch deep
- Cover with plastic wrap to retain humidity
- Place under grow lights or in a bright window
- Keep soil consistently damp but not soggy
- Transplant seedlings after hardening off for 7-10 days
Transplanting Store-Bought Plants
If you buy starter plants from a nursery, you can plant them a bit later. Wait until nighttime temperatures stay above 50°F consistently. This is usually 2-3 weeks after the last frost.
Hardening Off Process
Do not skip this step. Move plants outdoors for 2-3 hours on the first day, then increase time by an hour each day. Keep them in a sheltered spot away from wind.
Preparing Your Garden Site
Lemongrass needs full sun and well-draining soil. Michigan’s clay soil can be a problem. Amend it with compost or sand to improve drainage.
Soil Requirements
- pH between 6.0 and 7.5
- Rich in organic matter
- Loose and crumbly texture
- No standing water after rain
Container Growing Options
Many Michigan gardeners grow lemongrass in pots. This makes it easier to move indoors before frost. Use a 5-gallon container with drainage holes.
Planting Steps For Michigan Gardens
Follow these steps for the best results. Timing is everything when you live in a state with short summers.
- Choose a sunny spot that gets at least 6 hours of direct sunlight
- Dig a hole twice as wide as the root ball
- Mix in compost or slow-release fertilizer
- Place the plant at the same depth it was in the pot
- Space plants 18-24 inches apart
- Water deeply after planting
- Add 2-3 inches of mulch to retain moisture and suppress weeds
Care Throughout The Growing Season
Michigan summers can be humid and hot, which lemongrass loves. But you still need to provide consistent care.
Watering Schedule
Water deeply once a week if there is no rain. During dry spells, increase to twice a week. Lemongrass is drought-tolerant but grows best with regular moisture.
Fertilizing Tips
Use a balanced fertilizer like 10-10-10 every 4-6 weeks. Apply it around the base of the plant and water it in. Do not over-fertilize, as this can reduce flavor.
Pest And Disease Management
Lemongrass is generally pest-free in Michigan. Watch for spider mites in hot, dry weather. Rinse plants with a strong spray of water to dislodge them.
Extending The Season
Michigan’s first frost can arrive as early as September in the north. You need to plan ahead to get the most from your lemongrass.
Using Row Covers
Floating row covers can protect plants from light frosts. This gives you an extra 2-3 weeks of growth in the fall. Remove covers during the day if temperatures rise above 80°F.
Overwintering Indoors
Dig up a few stalks before the first hard frost. Pot them in containers and bring them inside. Place in a sunny window and water sparingly through winter.
Harvesting Your Lemongrass
You can start harvesting when stalks are about 12 inches tall. Cut stalks at ground level using sharp shears. Leave at least half the plant to continue growing.
Best Time To Harvest
Harvest in the morning when essential oils are most concentrated. This gives you the best flavor for teas and cooking. Stop harvesting 4 weeks before the first expected frost.
Common Mistakes Michigan Gardeners Make
Even experienced gardeners make errors with lemongrass. Avoid these pitfalls for a better harvest.
- Planting too early in cold soil
- Overwatering in heavy clay soil
- Not hardening off transplants
- Waiting too long to bring plants indoors
- Planting in partial shade
Regional Variations Within Michigan
The best time to plant lemongrass in Michigan varies by region. Here are specific dates for major areas.
Southeast Michigan
Detroit and Ann Arbor areas. Last frost is usually around May 10-15. Plant outdoors in late May.
West Michigan
Grand Rapids and Holland. Lake Michigan moderates temperatures. Plant in mid to late May.
Northern Michigan
Traverse City and Petoskey. Last frost can be as late as June 5. Wait until early June.
Upper Peninsula
Marquette and Sault Ste. Marie. Last frost is often June 10-15. Plant in mid-June.
Lemongrass Varieties For Michigan
Not all lemongrass varieties perform equally in Michigan’s climate. Choose ones that mature quickly.
East Indian Lemongrass
This is the most common type for culinary use. It grows well in containers and reaches harvest size in 90-100 days.
West Indian Lemongrass
Larger and more vigorous, but needs a longer season. Best for southern Michigan only.
Companion Planting Ideas
Lemongrass can benefit other plants in your garden. Its strong scent repels some pests.
- Plant near tomatoes to deter aphids
- Grow alongside peppers for mutual benefit
- Avoid planting near fennel or beans
- Use as a border plant to discourage rabbits
Using Lemongrass In Michigan Kitchens
Fresh lemongrass adds a citrusy flavor to many dishes. Michigan gardeners love using it in teas, soups, and stir-fries.
Simple Lemongrass Tea
Cut 4-5 stalks into 2-inch pieces. Bruise them with a knife. Steep in boiling water for 10 minutes. Strain and sweeten with honey.
Freezing For Winter Use
Chop fresh lemongrass and freeze it in ice cube trays with water. Pop out cubes and store in freezer bags. Use them in soups and curries all winter.
Troubleshooting Common Problems
If your lemongrass is not thriving, check these issues.
Yellowing Leaves
This usually means overwatering or poor drainage. Let the soil dry out between waterings. Improve drainage with sand or perlite.
Slow Growth
Not enough sunlight or nitrogen. Move plants to a sunnier spot. Apply a nitrogen-rich fertilizer like fish emulsion.
Stalks Falling Over
This can happen in windy areas. Stake plants or grow them in a sheltered location. Container plants can be moved to a protected spot.

Final Tips For Michigan Gardeners
Start your lemongrass seeds indoors in early March for the best results. This gives you a head start on the short growing season. Use a heat mat to speed germination.
Monitor soil temperature with a simple thermometer. Do not plant until the soil reaches 60°F at a depth of 4 inches. Cold soil will stunt growth and may cause root rot.
Consider using raised beds if your soil is heavy clay. They warm up faster in spring and drain better. This can extend your growing season by 2-3 weeks.
Keep a garden journal to track your planting dates and results. Over time, you will learn the best window for your specific microclimate. Michigan’s weather varies greatly from year to year.
Lemongrass is a rewarding plant for Michigan gardens. With proper timing and care, you can enjoy fresh stalks from summer through fall. The key is patience—wait for warm soil and frost-free nights.
