Gardeners' Notes:

Neutral Lilithu On Mar 20, 2011, Lilithu from Springfield, TN wrote:

I planted the seeds on 3/13/11 & already had seedlings popping up on 3/19/11. The thing is - I can't find any info on the way the seedlings actually emerge & grow. It seems as though they shoot up & then they seem to 'fall' over & start burrowing into the soil. I saw quite a few of them right on top of the soil - including the seed - & I tried to plant the seed again - but noticed the others trying to burrow back into the soil.

I decided to just put a few of them back in - seed first - so see what happens over the next few days. If anyone out there knows why they do this & if I'm doing the right thing - it would be greatly appreciated. *I've posted a new photo - seems that they were ok to begin with - still seem a little erratic.

Licorice root can be used as a sweetener & great for coughs & bronchial problems. Folklore states it can make you passionate!
