You can get lots of well researched information in a new online-publication called WNY Gardening Matters produced by the Cornell Cooperative Extension Master Gardeners in Erie County.
They plan to publish several articles online every month. They’ll let me know when new articles are available, and I’ll share them with you.
Here are the first two:
The yellow flag iris (Iris psuedacorus) is pretty, but it can get out of control and create problems along ponds, streams and wetlands. The article describes the flower and tells you what to do to control it.
If you are growing yellow flag iris in your garden, do you have to pull it out because it is an invasive species?
The Master Gardeners sent along this information from Andrea Locke, head of Western New York PRISM (Partnership for Regional Invasive Species Management).
The New York State regulations do not require people to remove yellow flag iris from their gardens.
However, to prevent the spread of an invasive species, Locke suggested removal if the plants are anywhere near a stream, pond or body of water where the seeds could disperse and spread. Also remove the plants if they are near the property edge where seeds could be dispersed off the property through mowing, weeding, etc.
Yellow flag iris contains an irritant, so wearing gloves when removing is recommended.
When removing the plants, put them in a sealed plastic bag and send it out with the trash. Don’t compost the plants because the rhizomes can remain viable for up to three months even without water.
Read the article for more information on the plant itself and how to control yellow flag iris.
This article outlines the steps for starting plants from seeds and points out pitfalls to avoid.
