How to Repot an English Lavender
Repot English Lavender every 2 to 3 years into a pot that's 1 to 2 inches wider than the current pot. Use a gritty, fast-draining mix of two parts standard potting soil and one part coarse perlite or pumice. Early spring is the best time, before the summer bloom flush begins.
How to Know It's Time to Repot
English Lavender is a woody Mediterranean shrub that prefers dry roots, so a too-small pot shows up as fewer blooms and tired-looking growth before it shows up below the soil. Watch for any of these four signals.
-
1Roots circle the bottom of the pot or push out through the drainage holes.
-
2The plant has roughly doubled in size since you last potted it up.
-
3Soil dries out within a day or two of a thorough watering.
-
4Bloom count drops noticeably compared to last year, even with the same care.
One sign on its own isn't enough to act on, but two or more together means it's time. Most English Lavenders need a fresh pot every 2 to 3 years, and the woody base eventually needs replacing with a fresh cutting after about five to seven years.
The Best Time of Year to Repot
English Lavender prefers a repot in early spring, just as fresh growth pushes from the woody base but before the summer bloom flush. The plant has the most energy to heal disturbed roots at this point in the season.
Avoid repotting in midsummer heat or while the plant is in full bloom, since the stress can cause flower drop and slow recovery. Use the map below to find your window.
How to Choose a Pot and Soil Mix
Pot Size
Move up to a pot that's 1 to 2 inches wider than the current pot. English Lavender prefers a snug pot with lean soil. Too much wet soil around the roots is the easiest way to rot a lavender, so resist the urge to jump several sizes up.
Pot Material
Terracotta is the best choice for English Lavender. The walls breathe, so the soil dries evenly between waterings, which matches what this Mediterranean shrub wants.
Plastic and glazed ceramic work too, but you'll need to water less often to compensate for the slower drying. Whichever material you pick, make sure the pot has drainage holes. Lavenders rot fast in standing water.
Soil Mix
Mix two parts standard potting soil with one part coarse perlite or pumice for the gritty, fast-draining blend English Lavender wants. A handful of crushed limestone or a small scoop of horticultural lime helps match the alkaline soils of its Mediterranean home.
Skip moisture-control formulas, peat-heavy mixes, and rich compost. All three hold too much water and feed the plant more than it wants.
How to Repot an English Lavender, Step by Step
-
1Water lightly the day before. Give the plant a light drink the day before repotting. Slightly moist soil holds the root ball together when you slide it out without making the roots water-logged.
-
2Pick the new pot. Choose a pot that's 1 to 2 inches wider than the current pot, with drainage holes. Layer an inch of fresh gritty mix in the bottom so the root ball will sit at the same height it did before.
-
3Slide the plant out. Tip the pot onto its side and gently work the root ball loose. Handle the plant by the woody base, never by the soft flowering stems. If the plant is stuck, run a butter knife around the inside edge of the pot to release it.
-
4Loosen the roots. Gently untangle any roots that have wound themselves into a tight circle at the bottom. Trim away any sections that are black, mushy, or smell sour, using clean scissors. Healthy lavender roots are firm and tan.
-
5Set it in the new pot. Center the plant at the same depth it was growing before. Fill in around the sides with fresh gritty mix, pressing gently as you go to remove air pockets. Topdress with a thin layer of small gravel to keep the woody base dry and reflect heat.
-
6Water and place in full sun. Water slowly until you see it run out the drainage holes. Set the plant in full sun, since lavender wants at least 6 hours of direct light a day. Hold off on fertilizer for 6 to 8 weeks so the roots can heal.
What to Expect After Repotting
Weeks 1 to 2
A slight wilt or a pause in new growth is normal as the roots settle into their new home. The silvery foliage may look a touch dull while the plant reestablishes.
Let the soil dry between waterings, give the plant full sun, and skip fertilizer for now. A drier-than-usual top inch of soil is exactly what lavender wants.
Weeks 3 to 6
Fresh silvery shoots emerging from the woody base and tips of the stems are the clearest signal that the plant has settled in.
Ease back into your regular watering rhythm, which for lavender means a deep drink only when the top two inches of soil are bone dry. Start half-strength liquid fertilizer once you see clear new growth, and stop feeding by midsummer.
