This has been a tough winter for snow and ice and we're starting to see more damage on some of our bricks and other paving areas that were salted this winter. To the left is some of the salting along our front paths just recently. Of course, visitor safey is extremely important so we do make all efforts to keep this entry path clear and are quite aggressive with clearing paths particularly during the Holiday Lights Show. However, de-icing salts can have a detrimental effect on garden plants, particularly during rough winters when salt applications seem to follow every snow and ice storm. It is important to remember that de-icing salts should be used to loosen snow and ice for removal and not used as the primary pavement "clearant". Over 11 million tons of road salt are spread on U.S. Highways each year which is an amazing amount of salt. I frequently see signs of salt (and salt spray) damage along the highways with browning pines, declining maples and other sensitive plants that wont tolerate salt and the increasing accumulation of salts in those soils. Of course, plantings along our highways in Northern climates should be selected for salt tolerance as it is an inevitability. Spring salt damage may appear as brown or yellow scorched leaves, stunted leaves or curled leaves. High salt levels in soils induce a "physiological drought" that affect the ability of plants to absorb sufficient water although it may be present in the soil. Excessive soil salts may also restrict the uptake of nutrients, induce twig dieback, induce early fall coloration on deciduous plants and can potentially be toxic. We use magnesium chloride de-icing salt at the gardens and although this type of salt, along with calcium chloride and potassium chloride, are less damaging than sodium chloride, there is no such thing as a "safe salt" when it comes to affecting plants. Consider the use of sand as an option and again, the minimal use of de-icing salts. A thorough and repetitive spring soaking of the soils with high salt concentrations may flush those salts deeper in to the subsoils and help mitigate some of the potential damage. However, the best approach is to minimize the applications of potential heavy salt loads in garden spaces and/or focus on those plants that are more salt-tolerant.
We had another good crew today with Larry, Marv, Terry and Dick W. heading out to remove and haul off about six trees that we've been waiting to take down. Dick H. was also here to assist as needed. We have some other "targets" out there and will address those this month. Urban was out to prune more crabapples while Pat and Dr. Gredler worked on painting the last our obelisks for this year. Dave, Vern, Bob A. and Jim worked on some special carpentry projects and have a full month ahead of them with carpentry projects (bench creation, etc.). Bill was in to help Larry later and Kay came in to work on her label processing. Janice was here in the afternoon and worked with Big John on their presentation for this Thursday evening (7 pm) entitled The Right Tool for the Right Job. Below is one of the ergonomic tool options that will be mentioned. We hope to get a great turnout for this event. We also saw Dave E., Jenny E., Chuck, Gary, Dick P.
More saturation marketing... Don't forget the Wednesday evening, March 30th (6 pm - 8 pm)talk on Herb Gardening by Patty Bailey of Patty's Plants - Natural & Organic Garden Supply. Check out her website at www.pattysplants.com. I've known Patty ever since I moved to Janesville (13 years ago) and am looking forward to her sharing her plant knowledge and palpable enthusiasm! Remember that RBG members are free with all others asked for a $5 donation for this lecture. I'm sure she'll say something about dill (Anethum graveolens) and my favorite variety, 'Fernleaf', can be seen below.







I've been working on more plant ordering and finalizing some presentations for early March. I speak at Olbrich tonight and will hopefully finish some other projects tomorrow. With my involvement with education this year, I attended the youth education com
Lots of planning and event preparations were in full swing today. I spent much of the morning compiling details on four of our six workshops that will be offered this year. In yesterday's blog I mentioned the mosaic birdhouse workshop on April 9th. This morning we finalized the details for some other exciting workshops. Sue M. did a nice job putting everything on our website and details for all four events can be viewed at
On July 30th (Saturday), there will be two opportunities. Unfortunately, they conflict in terms of timing but both should be well received. Shelley Ryan, host of the popular WPT show The Wisconsin Gardener, will be offering her silk scarf dyeing workshop (9 am - 11 am) that will utilize plants found out in the gardens. She will guide participants thru all the steps of this process and all participants end up with four scarves; three prepared by them and one done in advance by Shelley (see sample above). On that same day, Karen Mezera will be leading a rose workshop/tour (10 am - noon) that will address proper selection, soil preparation, maintenance, insect/disease issues, winterization, etc. regarding roses. She'll give a tour of the RBG rose collection and will address participant questions and provide rose care handouts. Karen is a past RBG volunteer, Master Gardener and is a consulting rosarian for the American Rose Society (ARS). She has been an ARS judge since 2005 and travels extensively for rose events and lectures on roses often.
Aside from workshop planning, I was able to make some more orders and continue to work on upcoming presentations. I'll present up at Olbrich Botanical Gardens (Madison, WI) tomorrow night on annuals and have a presentation this Saturday as well. Dr. Gredler and Bill worked on painting obelisks while Larry spent most of the day working on our CASE endloader and getting it ready for spring. Kay came in to work on plant sale labels and once that was complete, was drafted to help get handouts ready for upcoming presentations. We also saw Mary W., Gary, Jumbo Jim, Deb, Mike and L.P. Tree Service was here to grind up the pines (Holiday Lights Show) in to mulch for the gardens. Busy day! Dr. Gredler's gloves (below) always let you know what colors he's dabbling with that day! :)





Janice was in doing some work regarding our spring plant sale offerings which include lots of neat vegetable varieties. This prompted my blog topic for today. For the past five years, we've been offering plants of heirloom tomatoes and a wide range of variable veggies and herbs selected each year. Above is a shot of freshly sliced heirloom tomatoes f





I've been away in Pewaukee for the Midwest Perennial Conference and it was a fun and well attended event today. Above is the purple coneflower (Echinacea purpurea) variety 'Vintage Wine'. Coneflowers and many other perennials and plants were mentioned today with the five speakers. Jim and Shelly Garbe (Shady Acres Nursery), along with George and Liesl Radtke (W.E. Radtke Nursery) ran another successful event which was apparently the 25th symposium in this series. Last night, we all had dinner and I was able to meet the other speakers: Pam Duthie (author, landscape designer from the Chicago area), Steve Folz from the Cincinnati Zoo & Botanic Garden, Chuck Martin (Dow Gardens, Midland, MI) and Susan Martin (Walters Gardens, MI). The "plant speak" was fun and we had a great time. Pam and I realized that we were co-speakers over 10 years ago at a different event. All the presentations were well received. I went last and made sure I could fit my 180 images in my 1 hour time slot. There were about 300 attendees and I saw many people that I knew and was able to spend time with Ed Lyon and Richard Hawke (Chicago Botanic). Back to seed ordering tomorrow.



I did overlap with some of the Grumpies this morning and noted that the carpenters (Jim, Vern, Bob and Dave) were making great progress on our "blue pyramids". Look closely, does that pyramid look odd to you for any reason? They were scratching their heads on figuring out some measurements but were being well supervised by the characters below (Dick H., Pat, Marv and Urban from left to right respectively). We had a good crew this morning that also included Larry, Bill, Marianne, Janice, Mary and others. I was a bit out of the loop with everything going on but our focus will shift heavily to finishing seed organizing next week.
