Springtime will officially begin with the Vernal Equinox on Sunday, March 20, 2017 at 12:30 AM EDT in the Northern Hemisphere. The Vernal Equinox brings increasing daylight, warming temperatures and the rebirth of flora and fauna. The word equinox is derived from Latin meaning “equal night.” Thus the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of equal length.

Quick Tip on Iris Growing for early Spring (March-April-May)
Springtime is a time of the gardening year that is awaited with great anticipation by iris growers and general gardeners alike. There is an intense inner enjoyment to be had from viewing the new years growth of foliage emerging from the recently frozen ground. Some nice iris bloom is just around the corner.
Specifically regarding irises, there are a few items that need attention. First, a clean up is in order of any garden debris that accumulated over the winter, as you do this check the plantings for any signs of winter damage and resolve these. Types of things to look for are; winter kill (botrytis, a grey-black fungus) carefully remove and dispose those afflicted/do not compost these. Look for winter heave, that is your iris plants standing up out of the ground by the roots! This happens mostly on new plantings ...push them back down and perhaps add extra soil as required. Time to treat for iris borer if you control with chemicals, if you are controlling manually then the debris removal helps to remove any borer eggs that are typically found on the debris. Time to check your garden signage with your plant map in case any moved or disappeared over the winter. Also this is the time to put down any fertilizer around the iris plantings. They will respond well to the extra nutrients. A suggested fertilizer values for iris would be along the lines of 6-10-10, avoid using high nitrogen fertilizer as it can encourage rot problems. Lower first number which is the nitrogen, higher on the other two numbers will help to boost flower production and growth and contains enough nitrogen to provide optimum growth with a lower risk of bacterial soft rot. Take it easy on the fertilizer; a little goes a long way. Alfalfa is also an excellent supplemental addition that provides nice results.

The IRIS FIX for 2016 ...coming soon to your inbox
We are pleased to announce the return in 2016 of "The Iris Fix". The "Iris Fix" is a free e-mail subscription service available between early May and the summer. Each day (usually) you will receive an iris photograph via e-mail to enjoy. This is provided by Don McQueen of London, Ontario from his collection of very nice iris photographs taken in and around his garden. When you have had enough, all you need do is send him an e-mail saying "Thanks, but no thanks" and he will remove you from the mailing list. To subscribe, contact Don at email@example.com
Shown below is a previous "Iris Fix" photo from May 12, 2014; an example of the very nice iris photos you will receive.
Black Lightning (Chuck Chapman 2009) SDB, 14 inches H, A gorgeous and hardy ruffled black iris with a contrasting violet beard. It has four flowers per stalk and remains in bloom for a long time. Black Lightning has put up extra flower stalks in July, like its pod parent Ruby Eruption, but not enough to be sure that it will rebloom regularly in Ontario. Some more southerly growers will need to try this and let us know if it is a rebloomer. A far better grower then other black SDB that have been tried here. Quickly forms clumps.
