Lesson 1 · 3 min read
Lavender is a sun plant. Give it full sun — at least 6 to 8 hours of direct light a day, and more is better. Shade means fewer flowers, weaker stems and more disease.
Air matters almost as much as light. A breeze dries leaves after rain and keeps fungal problems down. A gentle slope is a gift: it sheds water and lets cold air drain away on frosty nights.
Walk your field the morning after a hard rain. Anywhere with standing water isn't lavender ground until you raise it.
Lesson 2 · 4 min read
More lavender dies from wet roots than from cold. Before you plant, find out how fast your ground drains. It takes an afternoon and a shovel.
| Water drops | What it means |
|---|---|
| About 1 inch or more per hour | Good drainage — plant in the ground or low rows. |
| About ½–1 inch per hour | Workable — plant on raised rows to be safe. |
| Less than ½ inch per hour | Poor — build raised rows or berms 8–12 inches high. |
Heavy clay isn't a deal-breaker. Plenty of Michigan lavender grows on raised rows over clay. The rows just have to lift the crown above wet soil.
Test in a few spots. One corner of a field can drain very differently from the rest.
Lesson 3 · 4 min read
A soil test is the cheapest insurance on a lavender field. Your state's extension service can test a sample for a small fee and tell you pH, organic matter and nutrients, with recommendations.
Lavender likes neutral to slightly alkaline soil — roughly pH 6.5 to 7.5 — and tolerates higher. If your soil is acidic, the report will tell you how much lime to add. Lime works slowly, so apply it the fall before you plant if you can.
Lavender does not want rich soil. Go easy on manure and high-nitrogen fertilizer. Lush, soft growth flops over, carries less fragrance and is more likely to be hurt over winter.
Test in the fall, lime in the fall, plant in the spring.
Lesson 1 · 4 min read
Most lavender farms are built on two groups:
| English lavender Lavandula angustifolia | Lavandin Lavandula × intermedia | |
|---|---|---|
| Plant | Compact, tidy mounds | Larger plants, long stems |
| Scent | Sweet and soft | Strong, with a camphor edge |
| Bloom | Early summer | A few weeks later |
| Best for | Culinary, fine oil, small bundles, landscape plants | Big bundles, crafts, sachets, higher oil yield |
Other lavenders — Spanish, French, woolly and more — are beautiful, but most are tender in cold winters. In the north, treat them as container or annual crops rather than field plants.
Lesson 2 · 3 min read
Before you pick a single cultivar, decide what you'll sell. The product tells you the plant.
| If you want to sell… | Look for… |
|---|---|
| Culinary lavender | English lavender — sweet, low camphor |
| Dried bundles & wands | Long-stemmed lavandins and taller English types |
| Essential oil | Lavandins for volume; English lavender for a finer oil |
| Fresh bouquets & U-pick | A mix of colors and bloom times |
| Garden plants | Compact English lavenders that look good in a pot |
Three to five cultivars is plenty for a first field. You can always add more once you know what sells.
Lesson 3 · 3 min read
Know your USDA hardiness zone and choose cultivars rated for it with a margin to spare. In zones 5 and 6, English lavenders and hardy lavandins are the backbone of most fields.
Plant a trial row of several cultivars before committing an acre. Your soil, wind and winter will tell you what thrives — and it only costs you a season.
Mixing early-blooming English lavender with later lavandins spreads harvest over more weeks, so you aren't trying to cut everything at once.
Lesson 1 · 4 min read
Lavender can stay productive for a decade or more, so design for the mature plant, not the little plug you put in the ground.
Measure your mower deck before you pick row spacing. You'll mow those aisles a hundred times.
Lesson 2 · 4 min read
The most labor-saving setup for a lavender field is simple:
Fabric cuts weeding dramatically in the first two years, when young plants can least afford competition. Drip under fabric puts water at the roots — not on the leaves and not on the weeds.
Lesson 3 · 3 min read
The formula is simple:
43,560 ÷ (in-row spacing in ft × row spacing in ft) = plants per acre
| Spacing | Plants per acre |
|---|---|
| 2 ft × 5 ft | 4,356 |
| 2 ft × 6 ft | 3,630 |
| 3 ft × 6 ft | 2,420 |
Add about 5% for replacements. Then turn plants into starts: one 72-cell tray plants 72 spots. Try the field calculator to run your own numbers.
Lesson 1 · 3 min read
Spring is the safest time in cold climates: plant after the danger of frost has passed and the soil is workable and warming. In West Michigan that's usually mid-May into June.
Fall planting can work in milder zones if roots get about 6–8 weeks to settle before the ground freezes. In zones 5 and 6, spring planting gives young plants a full season to root in before their first winter.
Plan backward: we recommend reserving your starts about six months ahead, so a late-May planting means ordering around Thanksgiving.
Lesson 2 · 4 min read
| Start | Good to know |
|---|---|
| 72-cell plug trays | The most plants per dollar for field planting. Young plants need attention the first few weeks. |
| 20-cell large plugs | Sturdier roots and a faster start in the field. |
| 4-inch & 1-gallon pots | The fastest to establish — great for gardens, small plots and landscape plantings. |
| Bare root | Large, dormant, soil-free plants (about a pound each). Plant or pot them up soon after they arrive. |
Shipping note: live plants in soil can't ship to AZ, CA, HI, ID, NV, OR, UT or WA because of state plant rules. Bare root plants are soil-free and can ship to those states.
Lesson 3 · 4 min read
In the first season, many growers pinch off the first flower spikes. It pushes the plant to build roots and branches instead of blooms.
Lavender dies from being planted too deep far more often than too shallow. Keep the crown up.
Lesson 1 · 3 min read
New plants need regular, deep watering until their roots are established — usually through the first growing season. Water deeply, then let the top inch or two of soil dry before watering again.
Drip irrigation is ideal: water goes to the roots and the leaves stay dry. Once established, most lavender needs little extra water except during real drought.
Overwatering and wet feet kill more lavender than drought ever does. When in doubt, check the soil with your finger before you water.
Lesson 2 · 3 min read
Weeds compete hardest in years one and two, before lavender fills in.
Lesson 3 · 3 min read
Lean soil makes tougher, more fragrant lavender. Base any fertilizer on your soil test.
Lesson 1 · 4 min read
Prune once a year, right after bloom or harvest. Take the plant back by about a third, shaping a rounded mound so rain and snow shed off.
Harvest is most of your pruning. Cut stems a couple of inches into the leafy growth and you've done both jobs at once.
Lesson 2 · 3 min read
In the Great Lakes region, cold, wet soil and freeze-thaw cycles do more damage than cold alone.
Lesson 3 · 3 min read
Don't rush spring pruning. Wait until new growth shows at the base and along the stems — often late April or May in Michigan.
Then trim dead tips back to where green begins. Some plants look dead in March and fill out by June, so be patient before you replace them.

Lesson 1 · 3 min read
| Harvest for… | Cut when… |
|---|---|
| Dried bundles & culinary buds | The first few flowers on each spike have opened. Color and scent hold best. |
| Fresh bouquets | Just a few flowers are open, so they last in the vase. |
| Essential oil | Later, when many of the flowers are open and oil is at its peak. |
Harvest in the morning, once the dew has dried. Wet stems mildew; afternoon heat wilts them.
Lesson 2 · 3 min read
Harvest and pruning happen in the same cut. Plan your harvest crew and your pruning together.
Lesson 3 · 4 min read
Hang bundles upside down in a dark, dry, well-ventilated space. Darkness keeps the color; airflow prevents mold. Drying often takes one to two weeks — bundles are ready when the stems snap.
For loose buds, rub dried bundles over a screen and bag them for sachets or culinary use.
Essential oil comes from steam distillation of fresh or lightly wilted flowers. Lavandins give more oil per acre; English lavender gives a finer, sweeter oil. If you sell culinary lavender, follow your state's food-safety rules.
Lesson 1 · 3 min read
Lavender can be sold many ways: fresh and dried bundles, loose buds, sachets and crafts, culinary lavender, oil and body products, bouquets, U-pick days and farm events, and plants.
Most small farms do best with two or three channels they can staff well. Start with what you can harvest, process and sell with the hands you have — then grow into more.
Lesson 2 · 4 min read
Before you sell, check the rules where you live. They vary from state to state:
Your state department of agriculture and county extension office are the best places to start. This lesson is general information, not legal advice.

| Year | What to expect |
|---|---|
| Year 1 | Establish roots. Little or no harvest. |
| Year 2 | A first, lighter harvest. |
| Year 3 on | Full production. Well-kept plants stay productive for a decade or more. |
Budget for plants, fabric, drip line, labor, drying space and packaging. Model it in Field Economics — or play a few seasons in the Farm Simulator — before you buy a single plant.
