Loving Basil

Basil, one of my top herb favorites, is getting some bad knocks lately. Normally a cinch to grow, Basil has been plagued by fatal downy mildew, which makes it unusable.

The latest malady to hit ornamental and food plants is Basil Downy Mildew, which has appeared in the last couple of years and is sweeping through the country like wildfire. It starts with leaf yellowing, which looks like a nutritional deficiency and then spots appear and can make the entire plant inedible. Under the right weather conditions (wet, warm weather), Basil downy mildew can spread rapidly and result in complete loss of all your Basil plants. Although Peronospora belbahrii, the pathogen that causes Basil downy mildew, cannot survive our mid-Atlantic winters, it can be reintroduced on infected seed or transplants or by windblown spores. So, it is here to stay.

Disfiguring my Basil plants by late spring/early summer, I despaired of growing this stalwart of my kitchen again. See my post African Blue and Downy Mildew for more information on this scourge.

Using Basil in many of my dishes, I always like to have some growing Basil plants on hand, but it can be hard to keep alive indoors.  I had almost given up growing it in any form and was buying the hydroponic plants at the grocery store as needed. Dried Basil is not the same flavor and addition to my cooking that I wanted.

Basil is an excellent source of vitamin K and manganese, copper, vitamin A (in the form of carotenoids such as beta-carotene), and vitamin C; and a good source of calcium, iron, folate, magnesium and omega-3 fatty acids. I had no idea this tasty herb was so good for you!

I was delighted to find a new cultivar of Basil called Amazel, a game changing plant, which is resistant to Downy Mildew. Growing in my greenhouse now, it will be planted outside as soon as the frosts subside so I can enjoy it fresh from the garden. Amazel is a hunky vigorous plant that I already have cut back twice in my greenhouse since January for pesto. Once I cut it back, fresh shoots sprout up and are ready in about 10 days to use again. I am back in the green with Amazel Basil from Proven Winners!

Amazel has excellent resistance to Downy Mildew, which will keep plants growing and producing for home gardeners throughout the entire season. Unlike typical basil, Amazel is seed sterile and therefore continues to produce leaves and shoots even after starting to flower unlike other basil varieties that focus most or all of their energy into seed production.

For other basil varieties that are resistant to Downy Mildew, go to my African Blue Basil post. I am back to pesto making again!

  1. Thank you for this valuable information. I have always grown basil and have never had any problems with it. I (or rather my husband) uses it in a lot of cooking. I’ll look for the Amazel Basil and give it a try.

  2. Thank you for the warning! I love growing basil and am glad to know about this problem before it gets to my garden.
