Fruits, Nuts & Perennial Crop CalendarsLavender Calendar
Lavender asks for sun, sharp drainage and light pruning at the right stage. This calendar helps you place each task around your own frost dates and rainfall.
Key points
- Drainage matters more than fertility.
- Plant after hard frost risk passes in most regions.
- Prune lightly and avoid old bare wood.
- Cut for drying as flowers open, and dry in shade.
What does lavender need to succeed?
Lavender prefers full sun, good air movement and soil that drains quickly. Wet winters and heavy clay are the main reasons plants decline, more than cold alone.
Types differ in hardiness, and no single lavender suits every region. Check your USDA hardiness zone for winter minimums, and remember the zone map does not give frost dates or planting dates.
Space plants so air moves between them, because humid, crowded plantings invite foliar disease. Your extension office can give spacing for the type you grow. Local climate guides from extension offices in dry, wet and cold regions often give very different advice, so read the one closest to you.
When should you plant lavender?
Spring planting after the last hard frost gives roots a full season to establish. In milder regions, fall planting can work if roots have time to settle before cold weather.
Raised beds or ridges help in wet ground. A soil test tells you pH, and lavender generally appreciates neutral to slightly alkaline soil, but follow your local recommendations for any amendment.
Test your soil before planting and again every few years, and treat nutrient advice as local, since rules and recommendations differ by state. Space plants according to the mature size listed by your supplier or extension source, and expect them to fill in over a couple of seasons. Crowding plants early to get a fuller look often leads to humidity problems later.
How should you water new plants?
Newly planted lavender needs steady moisture while roots grow. After establishment, it tolerates dry spells, and overwatering becomes the larger risk.
Water at the base, not overhead, and let the surface dry between waterings. Respect any local watering restrictions in your area.
Use gravel or coarse sand only if recommended by an extension source for your soil type, because some amendments help drainage and others make it worse. A drip line or soaker hose at the base is easier to manage than a sprinkler and keeps foliage dry.
- Water deeply but infrequently once established
- Avoid mulch piled against stems
- Improve drainage before adding water
When and how do you prune lavender?
Light pruning after flowering keeps plants compact. Avoid cutting into old, leafless wood, because many lavender plants do not regrow from it.
Timing of any heavier pruning depends on your climate. Utah State University Extension and other sources advise caution, so check an extension guide for your area.
Keep weeds down in the first two seasons so young lavender is not shaded or crowded. Pruning tools should be clean and sharp, and cuts should stay in green growth. Cutting back hard in late fall can leave plants exposed to winter damage in cold areas.
When is lavender ready to harvest?
For dried bundles, many growers cut when a portion of the flowers on each stem have opened, and fragrance is strongest. Cut in the morning after dew dries.
Hang stems in a shaded, airy place to dry. If you plan to sell lavender products, check state rules for labeling and food or cosmetic regulation.
Mulch choices matter in wet climates. Stone mulch can help keep crowns dry, while heavy organic mulch can hold moisture against stems. Harvest timing for oil, culinary use and decorative bundles can differ, and a single field can include all three if you plan the cutting days.
How do you protect lavender through winter?
Good drainage is the best winter protection. In cold areas, some growers use light coverings or windbreaks, but heavy mulch can trap moisture and rot crowns.
Keep notes on winter losses and where they occurred. Patterns often point to a wet spot or wind exposure you can fix next season.
Spent flower stems can be removed after bloom, and this also gives you a chance to look over each plant for dieback. In snowy areas, a winter cover of snow can actually protect crowns, but standing water in thaw periods is the real danger.
How do you plan lavender for sale or for home use?
Home plantings can be informal, but a field intended for sale needs a plan. Decide whether you will sell fresh bundles, dried stems, plants or finished products, because each choice affects variety selection, harvest timing and equipment.
Check your state and local rules on cosmetics, essential oils, food use and farm stand sales before you promise products to customers. Regulations vary, and your state department of agriculture can explain what applies.
Start small and expand after a couple of seasons. Lavender takes a few years to reach full size, and the first seasons show whether your site and climate are a good match.
