Garden Visit: Riverhill, The DiMattio Garden


There are many wonderful surprises one could encounter on a garden visit, but discovering there’s a garden potter amongst us in the Hudson Valley ranked high on the list of memorable for last season (2014). A September outing to Saugerties for Garden Conservancy Open Days brought us to Riverhill, the garden of Tamara and Joe DiMattio.


Five acres of hillside sloping down to the Hudson River are mighty impressive, but I couldn’t take my eyes off the ceramics that were to be seen everywhere – as ornament in the gardens and as part of the extensive potted plant collection distributed throughout.


Check out those hedges!


Luckiest cactus collection in the HV – with a front row seat to prime river view.




Now this is a window box. Are you feeling inspired too?


This garden photographer apologizes for being so predictable…but if there’s a begonia collection to capture and share, it’s going to happen.


We’re waiting patiently, sort of, for the Garden Conservancy to announce the Open Days schedule for 2015. In the meantime, you can check out their brand new website and be sure to sign up for email updates too.

DSC_0126HVGArdeners l-o-v-e garden outings, and everyone is welcome to join us. Invitations for future outings will be posted on our Facebook page. Don’t be shy! Garden and nursery exploring is more fun with other plant enthusiasts, don’t you agree? Who knows where this season will take us…suggestions are always welcome.

Program Spotlight: CCE Putnam Horticulture Hotline & Diagnostic Lab

Contributed by Susan Horan,
Master Gardener Volunteer Cornell Cooperative Extension of Putnam County

HVGA.DiagnosticLabPutnam County residents have questions about their soil, home landscape improvements, plant selection, wildlife control, plant care, eco-friendly garden practices, pest management and composting.

Where do they go for evidence-based advice? Master Gardener Volunteers staff the Horticulture Hotline and Diagnostic Lab to provide answers to these and other questions. They also identify plants and insects, test soil samples, and supply sound control recommendations with local conditions in mind.

The Cornell Cooperative Extension of Putnam County Horticulture Hotline receives over 500 calls a year and 100 plant, insect, disease and weed samples are brought in for diagnosis.  The abbreviated list of calls that come in include questions about plant, tree and lawn care, vegetable and flower gardening, and home and garden pest management.


Though they may look sinister, these are harmless firefly larvae. Master Gardener Volunteers were able to identify these insects, even as the homeowner was poised to spray them simply because they did not know what they were.







Master Gardener Volunteers (MGVs) answer many specific (and sometimes crazy) questions like, how do I stop the woodpecker from ruining the siding on my house, or how can I make the tree frogs outside my window be quiet at night?

Anita Conway, an experienced Master Gardener who volunteers on the hotline, feels that she is providing a very important service to the community whether she is helping someone save their dying memorial Japanese maple or if she is talking to a new gardener about environmentally safe gardening practices.

The examples mentioned above are a small percentage of the type of situations our Master Gardeners in the lab deal with.  In one case a community member brought in just the leg of an insect in a plastic bag and the MGV was actually able to figure out what the insect was and to offer help, suggesting ways to get the insect to stop eating the garden.  Using evidence based recommendations Master Gardener Volunteers help community members with least-toxic pesticide management options, invasive species identification, ecological lawn care, propagation of plants and tons of questions regarding why the Brown Marmorated Stink Bugs are invading homes in such large numbers.

10502346_728370367250118_8578955775617784448_nAs you can see, the hotline has a broad reach and is utilized extensively by the community. Our Master Gardeners tackle every challenge small or great – one leg or two. We hope you’ll call us with a question this year!

The Horticulture Hotline and Diagnostic Lab are open 9am to Noon weekdays (845)278-6738. If you wish to bring in a sample for testing or identification, please see our website here: www.cornell/edu/putnam and read the “horticulture diagnostic forms” for specific instructions.
