Tarragon -- My success after 3 years of failure
I've posted on this forum before about problems with French Tarragon. I just could not get it to grow. It kept getting brown and crispy. Too much water, too much sun, not enough water, not enough sun and on and on and on. Well this spring I purchased 2 very healthy Tarragon plants from a reputable herb farm and set out to kill them again. My research told me that French Tarragon has a really finicky root growth pattern with roots growing every-which-way.
I plant almost exclusively in containers and here is what I did.
I used a 20 gallon container with lots of drainage holes. I put a 3 pound bag of medium river rocks in the bottom to prevent the roots from sitting in wet soil. Then made a mix of pine bark fines, ProMix potting mix and PermaTill (tiny, tiny rocks) for my growing medium. Just to be on the safe side I did a soil drench of Actinovate. It has been 2 months and my Tarragon is healthy and growing nicely. The proof will be in the spring of 2014 - if the plant comes back.
I just wanted to thank everyone here who gave me advice over the years.
