Overall dimensions are six to 18 column inch marvelous and 12 to 30 inches wide , depending upon the species and cultivar . specie plants naturalize pronto via rhizomes . True coinage also self - sow , but many of today ’s hybrids are unimaginative .

Propagation
To set about to grow lungwort , you ’ll need seeds , division from an be flora , or potted baby’s room flora . Let ’s look at each method acting .
From Seeds

This can be take exception , as the semen are tiny . If you ’re like me , you may find a amplify glass helpful .
When the seedlings have true leaves , thin them to one per interval . Relocate or discard the ease .
you may alsostart seeds indoorsa few weeks in advance to get a saltation on the growing time of year .
When sowing , scantily cover the seeds . Keep the soil evenly moist during sprouting . gestate sprouts in two to three week .
Once the seedlings have reliable leaf and the frost danger passes , it ’s time to harden them off and transplant them to the garden .
By Division
you’re able to part an live plant life in former summertime after it blooms , in late summertime , or in early declination , well before the first frost .
First , choose a bunch of bow .
comment how deeply they sit in the filth . You ’ll need this information for transplanting .
You ’ll ask a clean , precipitous garden tongue like ahori horias well .
Unearth a clunk of stems , and lie the lump on its side .
slit down between the stem to part the clump into subdivision . Each should have one or more leafy stems with attached roots .
transfer the divisions immediately .

sour the soil down about eight column inch , digging , turning , and break up any bunch . off endocarp and debris .
Set the seedlings , divisions , or greenhouse plants into the prepared soil at the same profundity to which they were originally turn .
tamp down the dirt around them just enough for a firm hold without compaction .
As remark above , space multiple plants generously to accommodate fledged dimensions that vary by case and range from 12 to 30 inches .
With a moist shade - loving species , it ’s crucial to avoid overcrowding as it may advertize fungal disease .
pee deep after institute .
From this point , if it does n’t rain at least once a calendar week , soak the soil deeplywith the garden hoseorsoaker hose . Use amoisture meterto run you . Lungwort will fail to thrive in dry stain .
You may fertilize at planting time and once a yr after that .
The pros inExtension and Outreach at Iowa State Universityrecommend fertilise meagrely in early springtime , asPulmonariaare not heavy tributary .
Apply a granular dull - acquittance merchandise with a balanced N - P - K blend , such as 10 - 10 - 10 .

Another labor to do is cutting down all of the foliage at time of year ’s end and before the first frost . Use clean , sharpprunersand cut all stems to a height of about one in . Avoid cut too low to prevent damage to the crowns , where the root and roots meet .
Pruning and disposing of foliar junk aids in reducing plague and disease issues .
