Choosing the Best Lavender Varieties for Zone 7
The first step to a successful lavender patch in Zone 7 is selecting the right varieties. Not all lavenders are created equal when it comes to cold hardiness and heat tolerance. Let’s explore the top contenders that will truly shine in your garden.
English Lavender (Lavandula angustifolia)
English lavender is often considered the gold standard for Zone 7 gardeners. Despite its name, it’s native to the Mediterranean, but it handles a wide range of temperatures beautifully. These varieties are known for their incredibly fragrant flowers and essential oils.
They are generally hardy from Zone 5 to 9, making them a superb choice for your climate. Expect compact growth and intense fragrance.
- ‘Hidcote’: A classic, known for its deep purple flowers and compact, mounding habit. It’s incredibly resilient and perfect for borders.
- ‘Munstead’: Slightly lighter purple flowers and a more relaxed, airy growth habit than ‘Hidcote’. It blooms earlier and is very cold-hardy.
- ‘Lavender Lady’: An excellent choice for those who want to grow from seed, offering beautiful blooms in its first year.
Lavandin (Lavandula x intermedia)
Lavandins are hybrids of English lavender and Spike lavender (L. latifolia). They are larger, more vigorous plants, producing longer flower stalks and a more camphor-like scent, making them popular for sachets and dried arrangements. They are hardy in Zones 5-9.
If you have more space and want a dramatic display, lavandins are a fantastic option.
- ‘Grosso’: Perhaps the most popular lavandin, famous for its long, dark purple flower spikes and high oil content. It’s a prolific bloomer.
- ‘Provence’: Offers a softer purple flower and a slightly sweeter fragrance. It’s a vigorous grower and performs well in heat.
- ‘Phenomenal’: A newer, highly acclaimed variety known for its exceptional vigor, disease resistance, and robust growth. It tolerates humidity better than many other types.
Spanish Lavender (Lavandula stoechas)
Spanish lavender, with its distinctive “bunny ear” bracts atop the flower spikes, is a delightful addition. However, it’s generally less cold-hardy than English or Lavandin types, typically hardy in Zones 7-10. This means it will thrive in Zone 7, but might be more sensitive to extreme cold snaps.
It often blooms earlier than other lavenders, giving you an early burst of color. Ensure excellent drainage for these beauties.
Popular varieties include ‘Otto Quast’ and ‘Anouk’, both known for their striking blooms.
Site Selection and Soil Preparation for Zone 7 Lavender
Once you’ve chosen your varieties, getting the planting site right is paramount. Lavender needs specific conditions to flourish, and Zone 7 provides a great foundation if you meet its basic needs.
Sunshine is Key
Lavender absolutely adores the sun. For the healthiest plants and the most abundant blooms, choose a spot that receives at least 6-8 hours of direct sunlight per day. More is even better! A south-facing slope or an open area away from tall trees and buildings is ideal.
Drainage, Drainage, Drainage!
This cannot be stressed enough: lavender hates wet feet. Poor drainage is the number one killer of lavender plants. In their native Mediterranean habitat, they grow in rocky, sandy soils that drain quickly.
If your soil is heavy clay, you’ll need to amend it significantly. Here’s how:
- Perform a drainage test: Dig a hole about 12 inches deep and 12 inches wide. Fill it with water and let it drain. Once empty, fill it again. If the water takes longer than 4-6 hours to drain, your soil has poor drainage.
- Amend heavy soil: Mix in plenty of organic matter like compost, well-rotted manure, and especially coarse sand or small gravel. You want to create a loose, friable soil structure.
- Consider raised beds or mounds: If your soil is particularly stubborn, planting lavender in raised beds or on small mounds (6-12 inches high) can significantly improve drainage and prevent root rot.
Ideal Soil pH
Lavender prefers slightly alkaline to neutral soil, with a pH range of 6.5 to 7.5. If your soil is very acidic (common in many parts of Zone 7), you can raise the pH by adding garden lime or wood ash. A soil test kit can help you determine your current pH level.
Planting Your Lavender Plants for Zone 7
With the right location and soil prepared, you’re ready to plant! Timing is important for giving your lavender the best start.
When to Plant
The best time to plant lavender in Zone 7 is in the spring after the last danger of frost has passed, typically late April to early May. This gives the plants ample time to establish their root systems before the heat of summer and the chill of winter.
You can also plant in early fall (September to early October) if you allow at least 6-8 weeks before the first hard frost. This is especially good for English lavender varieties.
Step-by-Step Planting Guide
- Dig the Hole: Dig a hole twice as wide as the root ball and just as deep. This allows the roots to spread out easily.
- Remove from Container: Gently remove the lavender plant from its nursery container. Loosen any circling roots at the bottom with your fingers.
- Position the Plant: Place the plant in the hole so that the top of the root ball is level with, or slightly above, the surrounding soil line. Remember, good drainage is key!
- Backfill and Water: Backfill the hole with your amended soil, gently firming it around the root ball. Water thoroughly immediately after planting to settle the soil and eliminate air pockets.
- Space Appropriately: Give your lavender plants plenty of room to grow. English lavenders usually need 12-18 inches between plants, while larger lavandins might need 24-36 inches. Good air circulation helps prevent fungal diseases.
Essential Care for Thriving Zone 7 Lavender
Once your lavender is in the ground, a consistent care routine will ensure robust growth and abundant blooms. It’s surprisingly low-maintenance once established, but a few key practices make all the difference.
Watering Wisdom
Young, newly planted lavender needs regular watering to establish its roots. Water deeply once or twice a week for the first season, especially during dry spells. Always check the soil moisture before watering; it should be dry a few inches down.
Once established (after about a year), lavender is very drought-tolerant. In Zone 7, you’ll likely only need to water during extended dry periods or severe heatwaves. Overwatering is far more damaging than underwatering.
Fertilizing (or Lack Thereof)
Lavender thrives in lean, even poor, soil. It generally does not require fertilizer. In fact, too much fertilizer, especially high-nitrogen fertilizers, can lead to lush green growth at the expense of flowers and fragrance.
If your soil is truly depleted, a light application of compost around the base of the plant in spring can provide a gentle nutrient boost. Avoid chemical fertilizers.
The Art of Pruning Lavender
Pruning is crucial for keeping your lavender plants healthy, bushy, and floriferous. Without it, they can become woody, leggy, and produce fewer flowers.
Annual Pruning
The main pruning should happen in early spring, just as new growth begins to emerge. Don’t wait until summer!
- Cut back about one-third of the plant’s overall size, aiming to maintain a compact, mounding shape.
- Always cut into the leafy growth, avoiding cutting back into old, woody stems that have no green leaves, as these rarely resprout.
- Remove any dead, damaged, or diseased branches.
Deadheading (Optional but Recommended)
After the first flush of blooms, you can deadhead the spent flower stalks. This can encourage a second, smaller flush of blooms later in the season. Simply snip off the flower stalks just above the foliage.
Protecting Lavender Plants for Zone 7 Winters
While Zone 7 is generally favorable for lavender, winter protection can make a big difference, especially for younger plants or during unusually harsh winters.
Mulch for Insulation
A light layer of mulch can help insulate the roots. However, choose your mulch carefully. Avoid heavy, moisture-retaining mulches like shredded bark, which can trap moisture and lead to rot.
Instead, opt for something coarse and airy like gravel, pine needles, or a very thin layer of straw. Apply it around the base of the plant in late fall, but pull it back slightly from the crown to prevent moisture buildup.
Ensuring Air Circulation
Good air circulation is vital year-round, but especially in winter. Snow cover can actually provide good insulation, but if your plants are packed too closely or in a sheltered, humid spot, they can suffer from fungal issues. Ensure your planting scheme allows for plenty of space.
Container-Grown Lavender
If you’re growing lavender in pots, these plants are more vulnerable to winter cold. The roots are exposed to freezing temperatures from all sides. For containerized lavender plants for Zone 7, consider moving them to a sheltered location, such as an unheated garage or shed, for the coldest months. Alternatively, you can wrap the pots in burlap or bubble wrap for extra insulation.
Common Challenges and Solutions
Even the most experienced gardeners encounter issues. Here are some common problems with lavender and how to tackle them.
Root Rot
Problem: Yellowing leaves, wilting, and eventual death, especially if the soil is consistently wet.
Solution: Improve drainage immediately! If the plant isn’t too far gone, carefully dig it up, amend the soil with more grit, and replant. For future plantings, choose a well-drained site or use raised beds.
Fungal Diseases (e.g., Gray Mold)
Problem: Fuzzy gray growth on leaves or stems, especially in humid conditions.
Solution: Ensure good air circulation by proper spacing and pruning. Remove affected parts immediately. Avoid overhead watering; water at the base of the plant. A fungicide can be used as a last resort, but prevention is best.
Leggy or Woody Plants
Problem: Plants with long, bare stems and few flowers.
Solution: This is usually due to insufficient pruning. Start a regular annual pruning routine in early spring. For severely woody plants, you might need to replace them, as lavender doesn’t always recover well from being cut back into old wood.
Pests
Lavender is generally pest-resistant due to its strong scent. Occasionally, you might see aphids or spittlebugs.
Solution: A strong spray of water can dislodge aphids. For spittlebugs, simply wash away the “spittle” and the bug within. Healthy plants are less susceptible to pests.
Harvesting and Enjoying Your Lavender
The best part about growing lavender is, of course, enjoying its bounty! Harvesting at the right time ensures maximum fragrance and beauty.
When to Harvest
Harvest your lavender when the flower buds have just opened, but before all the individual flowers on the spike are fully open. This is when the essential oil content and fragrance are at their peak.
Choose a dry, sunny morning after the dew has evaporated. This prevents mold and ensures the highest quality harvest.
How to Harvest
Use sharp, clean pruning shears or scissors. Gather stalks into small bundles and cut them about 4-6 inches above the foliage. Don’t be shy – harvesting is a form of pruning and encourages more blooms!
Drying and Using Lavender
Tie your harvested bundles with string and hang them upside down in a cool, dark, well-ventilated area. Drying can take 1-3 weeks depending on humidity. Once dry, the flowers will hold their shape and fragrance.
You can use dried lavender for:
- Sachets: Place in drawers or closets for a fresh scent.
- Potpourri: Mix with other dried botanicals.
- Culinary uses: English lavender varieties are excellent for baking, teas, and flavoring dishes.
- Crafts: Wreaths, arrangements, and more.
