Pulmonarias do best in a highly organic, moisture retentive soil. Dry conditions can lead to powdery mildew and leaf scorch. Clean up in the spring by removing old or damaged foliage from the previous year. Some of the older cultivars can open up in the center and thus it becomes necessary to prune them down to ground level for a new fresh flush of foliage. If plants decline or are affected by powdery mildew, prune them back to ground level as well.

Pulmonarias spread slowly by creeping rhizomes, forming a nice patch of foliage.

Growing Temperature:

55-60° F

Soil PH:

5.6-6.8

EC (What is EC?):

2.0-2.5 pour through method

Fertility:

Apply a balanced fertilizer with micronutrients at 150 ppm in a constant liquid feed.

For Controlled Release or Slow Release Fertilizer, see your preferred supplier for recommended rates for incorporation or top dressing, as it varies by fertilizer.

Vernalization:

For flowering plants use vernalized liners for spring planting or provide 8-10 weeks of cold temperatures if planting in late summer.

Pests & Diseases:

Aphids and slugs.
Powdery mildew. Botrytis can occur on older leaves at soil level under high humidity conditions. Running a heat/vent dehumidifying cycle, increasing air circulation, and applying fungicides as necessary should keep this disease under control. Pythium and Rhizoctonia can become a problem if the growing media does not have good drainage.

Potting & Timing:

Recently transplanted pulmonaria are happiest at 65% humidity and 65-70°F until they are halfway rooted. They can then be cooled down to 55-60°F.

Moisture:

For potting soil use commercial planting media.
Keep soil evenly moist but with good drainage, and do not allow plants to dry out between waterings. Due to heavy foliage growth and high water usage, this plant is a good candidate for sub-irrigation.

Planting Level:

Plant at crown level.

PGRs/Pinching:

No pinching or PGRs required.

Lighting:

Provide moderate shade in spring and summer production.
