Planting and Caring for Lavender (in the South)
Varieties of Lavender
There are many lavender varieties that grow well in our area. The lavandins are good choices or Lavandula x intermedia varieties like Grosso and Provence. Lavandula angustifolia, like Hidcote, grows well in our region, too. Lavender will thrive when properly planted. Make sure the lavender chosen is hardy in your Planting Zone. The farm is located in Zone 7a. Our farm offers plants at events both on and off of the farm, in the spring and in the fall. Since lavender plants do not like to be confined to a sweaty box, our farm does not ship live plants.
How to Plant Lavender
- Use well-drained soils or raised beds and containers (outdoors only).
- Soil should be sandy/loam or gravelly. Be sure to amend clay.
- Soil should have low fertility.
- Alkaline soil pH should be at least 6.5 or higher.
- Create an 18″ – 24″ mound with well cultivated soil and 2 heaping shovelfuls of 1″ round stone worked into the mound. Err on the side of too much stone. May create a French drain by placing fist sized rocks in mound base.
- Using a trowel, dig a hole just deep enough for the plant.
- Add ½ cup total of equal parts of bone meal, lime and well composted manure in the bottom of hole and mix well. The stone will allow the soil to drain, the lime will improve the pH, bone meal and compost for a healthy start.
PLANTING & TRANSPLANTING
As long as the soil can be cultivated, plant lavender. Avoid planting in July, August, December and January. Lots of lavender goes into French lavender fields in February!
- Water your lavender well in its nursery pot and let it sit for an hour or more before planting.
- Prune the top of the plant to ensure a productive plant.
- Loosen the roots from the potting soil by working the trowel teeth into the soil block.
- Place plant just above the blend of stone/ lime / bonemeal / compost, not allowing the roots to touch the blend and gather soil around base of plant. Water deeply.
- Space largest plants 5 – 6 feet from one another for good air circulation.
- Lavender blooms at its peak in its third year producing about 1000 stems
Herbs thrive on neglect once established.
Care for your lavender as you would any new perennial, watering deeply (or measure 1″ of rainfall) every 7–10 days for the first two years. Once it is well-rooted, lavender is tolerant of heat and dry spells. Water lavender if there is a drought. Caution! Over watering leads to root rot which will cause lavender to die. Prevent weeds by mulching with a light-colored mulch like shells or gravel. Do not use hardwood mulch. The sun will reflect light, keeping the plants dry and helping to deter disease and enhance bloom and oil production.
♡ Prune after the coldest part of winter in your area, around Valentine’s Day.
Trim off 1/3 of lavender foliage, leaving at least 2–3″ of green, taking care not to cut into the woody part of the plant, in late winter while dormant, by the end of February (in Zone 7a). Pruning will help the plant grow full and rounded and deter sprawling, which can cause the main stems to split and break. Toss a handful of bone meal/lime/compost blend around base of plant in the fall just before rain or water afterwards.
The lavender varieties that grow well in our area will bloom from about Memorial Day to July 4th.
Sometimes lavender will bloom a second time in the fall. Now, this will not be as abundant a show as in June. In our field, it is oftentimes the varieties that bloom the earliest, such as Hidcote, that give us the fall show. If the plant is harvested at peak bloom, when the first flowers begin to open, and the foliage is sheared back some at the same time, in September, there is a colorful and fragrant surprise.
To harvest lavender, when the bottom flowers are just opening, the lavender is at its peak for color and fragrance, cut the stems down to the foliage. Gather about 100 stems and rubber band them together. You may turn them up-side-down, suspended from a nail, string or wire in a hot, dark, dry location for drying, like an attic, storage area or closet. Allow the lavender to dry for about 10-14 days, depending on the conditions.
Keeping Fresh Lavender
If you enjoy fresh lavender in the house, cut it when it blooms and do not place it in water. The water just accelerates the florets falling off of the stems and the stems get very mushy, messy and yes, smelly. So, just cut them, place them in a vase, bottle, basket — whatever! — and enjoy. They will dry on their own. Grosso and Hidcote dry very nicely this way and the florets stay on the stem quite well.
Place the fresh flowers away from direct sunlight for the best dried color. Provence naturally dries to a light lavender/gray color and tends to fall right off of the stem once dried, so gather up those flowers for your potpourri and don’t get frustrated. Remember, the hotter and darker, the better lavender color and fragrance!
Quick Tips for Growing Lavender
1. Full Sun At least 6 hours. Full throttle!
2. Excellent Drainage Like rock gardens & raised beds – lots of stone.
3. Air Circulation 4 inch pots grow into 3 foot diameter shrubs. Keep clear of any creeping ground cover, or weeds, of course.
4. Prune Annually Leave 2-3 inches of soft green. Do not cut into the hardwood. Prune around Valentine’s Day or after the coldest part of the winter.
5. Water Deeply Lavender prefers soakings every 7-10 days. 1 inch of rainfall weekly is perfect.
6. Reflective Mulch Stone and shell. No hardwood mulch, please.
7. Suggested sites for lavender. Remember – Hot, Dry and High!
- Southwestern exposure
- Slopes or banks
- Pool side
- Along a stone wall

We’ve done our very best to collect and share our knowledge here with you! Because we also have full-time jobs outside of the farm, it is our regret that all inquiries about lavender farming will be re-directed to this very page. You may want to reach out to your local Cooperative Extension horticulture agent who will have terrific knowledge about growing in your location or a local nursery may also offer variety suggestions and more. Volunteer Master Gardeners are also a wealth of information. Then, there is also the Internet! Thank you for your understanding.
