The tour will be held at
Ramsey County's Battle Creek Regional Park

Master Gardeners from ANY county welcome. CE hours: 3

We will hike through the park to get a close-up look at invasive plants that are beginning to move into our area: narrowleaf bittercress, Japanese knotweed and Japanese hedge parsley.  We will also see garlic mustard.  Potted and pressed samples of other new invasive plant species that are on our watch list will be available to see.

Bring a water bottle and lunch if you'd like. Some extra water will be available.  Please wear sturdy shoes and dress for the weather and off trail hiking!

Carpooling recommended!  We will meet in the Point Douglas Road parking lot at 9:00 am sharp.  To get there, take Lower Afton Road to Point Douglas Road South and turn north.

As you are out and about this summer, keep a lookout for common/European buckthorn trees withBuckthorn phytoplasma flyer.jpg witches' broom/yellows disease symptoms.

Laura Van Riper, Terrestrial Invasive Species Coordinator of the Division of Ecological and Water Resources, Minnesota Department of Natural Resources reports: "Research to identify biocontrol insects for buckthorn has been on-going since 2001. A phytoplasma disease was detected in potential biocontrol insects and Rhamnus species in Europe. It has not been reported in the US. We need to know if this phytoplasma is already present in North America."

We need your help! Click Buckthorn phytoplasma flyer.pdf for details and photos.

From Larry Cipolla, Former MG State Advisory Board President and UMN Ext Master Gardener - Hennepin Cty:

On behalf of the State Master Gardener program and the Minnesota State Horticultural Society, I would like to invite you to join me and our many local experts on this very special garden and cultural tour of Singapore and Vietnam. We will tour a wide range of tropical public and private gardens, including a visit to one of the largest collections of Orchids in the world.

P1090965.JPGThe tour will include travel by air, boat, bus, train, and even some walking. Ever taken a ride on the world's largest Ferris wheel? We will and you can too. We will enjoy Chandon champagne, chocolates, and strawberries as we do. We will go on a night safari to experience the sights and sounds of wildlife in a tropical jungle. We will take some refreshments at the famous Raffles Hotel. We will stay overnight on a traditional Chinese-style Junk in Halong Bay (Gulf of Tongkin). You will even learn how to cook Vietnamese food in one of the premier cooking schools in Hanoi. And, just in case you like to shop, there will be time to shop for silk clothes, Batik shirts, ceramics, and pretty much whatever you are looking for. Leave space in your suitcase!

 Want to learn more? Click Singapore & Vietnam Tour.pdf to download the brochure. It details this 12-night 13-day journey to one of the most modern countries and one of the most picturesque in all of SE Asia. The tour is limited to 20 people.

 I look forward to having you join us!

  • How to work with communities and homeowners as a Community Tree Inventory Volunteer
No experience or special knowledge required - just dedication volunteers who want to help your community. (Master Gardeners - get your friends and neighbors involved!)

8.5 hrs continuing education to become a Community Outreach Volunteers about urban forestry. By completing both the 12-16 hours and the additional 8. 5 hours of education, you will be certified as a Tree Care Advisor.

P1130177.JPGMaster Gardener Summer School in Andover was a day of great education including hands-on opportunities with turfgrass, diagnostics, tree pruning, noxious weeds, and fruits. Fifty-two Master Gardeners completed the day and earned 7.5 hours of continuing education that they can REALLY use!

Some comments from the post Summer School survey:

"Instructors knowledge was wonderful and they were all very good at sharing their knowledge. A winning combination."

"The Turf class by Bob was excellent! I finally figured out how to tell creeping Bent from a Rough Bluegrass! Yeah!"

"What a great way to share the latest and greatest field tested information. As new research comes in it changes how we practice gardening. This summer school session was a great way for us to obtain this cutting edge knowledge. Being able to bring this knowledge back to our MG peers and our community - priceless!"

"The hands on approach was the best way for us to not only get the information but allow us to put it to practice it in the field. This field based learning approach definitely increased my retention of the new information."P1130532.JPG

Answer from John Loegering, Associate Professor -- UMC Agriculture/Nat Resources

There is no way to move an active nest. Either you wait or you just kill the babies . . . both are messy.  THEN, clean the old nest from the building.  Nothing says 'try to nest here' more than an old nest.

Dissuading swallows in the first place is all about harassment.  Do not let them start a nest.  If they start, knock it down.  Knock it down twice a day during building and they get the hint after a few days. . . . . usually.  Some are more stubborn than others (just like people).

A good place to nest is just that, so any place a swallow has nested before is a good place for another to try.  It is very unlikely it is the same bird coming back.

P1030295.JPGSome of you know I have long been a proponent of vermicomposting and find worms quite interesting! I had a worm bin for quite a few years, but no longer keep one. There's a great bit of news for all of you who are worm-lovers including some very cool, one-of-a-kind video of worms doing their thing. Cick here
