How to collect or dispose of firewood and brush without compromising forest health.
This year has been a rollercoaster of good (e.g. continued progress on the long term fight against emerald ash borer) and bad (e.g. sudden oak death potentially being introduced into the Midwest) news about invasive species. There’s been a lot to keep track of, but don’t worry if you’ve missed anything. You can learn all the details, get a chance to ask experts questions, and get CE credit (ISA, CCH, SAF, Master Gardeners and Naturalists, etc.) in this fall’s free EABU webinars. Register to watch live or later at http://www.emeraldashborer.info/eabu.php Can’t watch it live? No problem! All webinars are recorded and posted online after the talks. Make sure to register to be notified when the videos are posted. CEU credits will be offered (ISA, CCH, SAF, Master Gardeners and Naturalists).

A new publication for nursery growers has been released! This publication, a joint venture between Purdue University and Indiana Department of Natural Resources, informs that nursery and landscape industry about new state regulations regarding invasive plants. The rule goes into effect in two stages. As of April 18, 2019, it is illegal to introduce a plant species (from the list of 44) if it is not already in Indiana. Listed plant species already in trade will be restricted from sale one year later (April 2020). The one-year grace period is designed to reduce the economic impact on the nursery industry by allowing time to sell down existing stock and adjust production.

Q: I’ve attached pictures of the only tree we have on our property. Because it is our only tree, I am deeply concerned with the possibilities of irreparable damage to it. As you can see, one of the branches broke off during a November windstorm. Unfortunately, that left a bare gap on the trunk. Please let me know how to treat this damaged area so no further damage is done to it and tell me what can be done to preserve its longevity. I do not know the name of this tree but it’s local. It is found almost everywhere in this area. It blooms white flowers in the spring that fall off shortly after and changes to beautiful colors in the fall. As you can see, it is a beautiful tree. Please help and thank you so much. – L. G., Valparaiso, Indiana A: To answer the second part of[Read More…]
The Invasive Terrestrial Plant Rule was signed by Governor Holcomb and published on March 18, 2019. The rule goes into effect 30 days after publishing, so it will be effective later in April. The rule states with respect to the 44 plant species included on the rule: “a person must not: (1) Sell, offer or grow for sale, gift, barter, exchange, or distribute a species; (2) Transport or transfer a species; or (3) Introduce a species. (4) Subdivisions (1) and (2) of this subsection are effective one year after the effective date of this rule.” Note that section (3) “Introduce a species” is effective immediately (around April 16, 2019). Selling, offering, distributing and transport doesn’t go into effect until April of 2020, so nurseries will have some time to sell down their stock. This is an important component of the rule to minimize economic loss to nurseries that grow and/or[Read More…]
