Common Issues

Poor Germination

Cause: Lavender seed germinates slowly and unevenly.

Prevention: Use bottom warmth around 70°F and do not bury seed deeply.

Crown Rot

Cause: Wet or waterlogged soil, especially in winter.

Prevention: Use raised beds, gravelly soil, and stone mulch.

Humidity Decline

Cause: Poor airflow and damp foliage shorten plant life.

Prevention: Space widely and avoid crowding or overhead irrigation.

What you'll need

Growing Supplies

Based on English Lavender's growth profile -- recommendations matched to this variety's specific requirements.

Drip irrigation / soaker hose kit

Every gardener benefits from putting water at the root zone instead of on the leaves, because drip and soaker systems reduce foliar disease pressure by limiting leaf wetness and soil splash. A quality kit should include a backflow preventer, filter, pressure reducer, and UV-resistant tubing.

Soil test kit

A soil test gives a baseline for pH and nutrient status so gardeners can add only what the soil actually needs. Prioritize a mail-in or lab-affiliated kit whenever possible because extension guidance notes that laboratory testing is more accurate than instant readers.

Quality bypass pruners

Extension guidance favors bypass designs because they make cleaner, closer cuts on living tissue than anvil types. Look for hardened steel blades that can be sharpened, a comfortable grip, and a cutting capacity matched to real home-garden stems.
