Growing lavender in Pennsylvania is absolutely possible when you choose the right varieties and give this Mediterranean herb the conditions it craves.
If you’ve been wondering how to grow lavender in Pennsylvania, you’re in luck because the Keystone State offers some great opportunities despite its humid summers and cold winters.
Learning how to grow lavender in Pennsylvania means understanding that lavender hates wet feet and loves sunshine, so you’ll need to pick the perfect spot and amend your soil properly.
In this post, we’ll cover everything you need to know about how to grow lavender in Pennsylvania, from selecting the right type to keeping it alive through winter.
Let’s dig in.
Why Growing Lavender in Pennsylvania Takes a Bit of Strategy
Growing lavender in Pennsylvania takes a bit of strategy because our climate isn’t exactly the Mediterranean dream this plant prefers.
Pennsylvania sits in USDA zones 5 through 7, which means winters can get cold enough to kill tender lavender varieties.
Our summers also bring high humidity that can lead to root rot and fungal issues if you’re not careful.
But don’t worry, because growing lavender in Pennsylvania is still very doable when you follow a few smart rules.
1. Choose Cold-Hardy Varieties
The first step in how to grow lavender in Pennsylvania is picking the right variety.
English lavender (Lavandula angustifolia) is your best bet because it tolerates cold down to zone 5.
Look for varieties like ‘Munstead,’ ‘Hidcote,’ and ‘Phenomenal,’ which are known for their winter hardiness.
Avoid Spanish and French lavenders, as these tender types usually won’t survive a Pennsylvania winter.
2. Understand Your Hardiness Zone
Knowing your specific zone helps you grow lavender in Pennsylvania more successfully.
If you’re in zone 5, stick strictly to English lavender and give it extra winter protection.
Gardeners in zones 6 and 7 have a bit more flexibility and can experiment with some hybrid varieties.
3. Pick a Sunny, Well-Drained Spot
Lavender needs at least six to eight hours of full sun to thrive.
When growing lavender in Pennsylvania, a south-facing slope or raised bed works best because water drains away quickly.
Low spots that collect water are a death sentence for this plant.
How to Plant Lavender in Pennsylvania
Knowing how to plant lavender in Pennsylvania correctly gives your plants a strong start.
The biggest challenge is our clay-heavy soil, which holds moisture and suffocates lavender roots.
Here’s how to tackle it.
1. Amend the Soil Generously
Mix sand, gravel, or perlite into your soil to improve drainage before planting lavender in Pennsylvania.
Aim for a slightly alkaline pH between 6.5 and 7.5.
If your soil is acidic, add a little lime to sweeten it up.
2. Build a Raised Bed
One of the easiest ways to grow lavender in Pennsylvania is by planting in a raised bed.
This lifts the roots above soggy ground and gives you total control over the soil mix.
Fill your bed with a blend of potting soil, coarse sand, and compost.
3. Plant in Spring After Frost
Wait until all danger of frost has passed in spring to plant lavender in Pennsylvania.
Space plants about 12 to 18 inches apart to allow good airflow, which helps prevent disease.
Water deeply once after planting, then let the soil dry out before watering again.
Caring for Lavender in Pennsylvania Through the Seasons
Ongoing care makes all the difference when you grow lavender in Pennsylvania.
Each season brings its own tasks to keep your plants happy and healthy.
1. Water Sparingly
Lavender is drought-tolerant once established, so water only when the top inch of soil feels dry.
Overwatering is the number one killer of lavender in Pennsylvania’s humid climate.
2. Prune Twice a Year
Prune your lavender lightly in early spring to shape it and remove winter dieback.
After blooming, shear back about a third of the plant to encourage bushier growth.
Never cut into the woody stems, as they won’t regrow.
3. Protect Through Winter
Winter survival is key when you grow lavender in Pennsylvania.
After the ground freezes, mound mulch or straw around the base, but keep it away from the stems.
This insulates the roots without trapping moisture against the crown.
4. Watch for Pests and Disease
Good airflow and dry conditions prevent most problems for lavender in Pennsylvania.
Watch for root rot in wet spells and treat spittlebugs or aphids with a strong spray of water.
So, How Do You Grow Lavender in Pennsylvania?
You can grow lavender in Pennsylvania by choosing cold-hardy English varieties and giving them sun, sharp drainage, and careful winter protection.
While our humid summers and freezing winters pose challenges, a little planning goes a long way.
With the right soil, smart watering habits, and seasonal care, your lavender will reward you with fragrant blooms year after year.
