In South Carolina, where many of our ponds have been constructed in clay soils, pond water quality may be less than ideal for fish management. Liming can be an important step in a productive and healthy fish pond as lime can improve pH, hardness, and alkalinity conditions, all important factors in fish health. For highly-fished, low-flow ponds where fertilization may be needed to support a beneficial phytoplankton community, liming may be required for effective fertilizer applications. (Contact your local Extension agent to find out more information on pond fertilization and if it is appropriate for your pond.)

By now, everyone involved with gardening or growing plants has heard the term “soil health” thrown around. What is soil health, and why is it important?

If you said Heuchera, you’re right. Perhaps you’re going to reshuffle some shady beds this spring, and know that Heuchera, with their great foliage, can help make garden pictures work–but wonder which ones, and how best to use them. I invited George Coombs, trial garden manager at the must-visit Mt. Cuba Center in Delaware, with 50 acres of native-plant display gardens and 500 acres of natural land, back to the radio show to help make the best choices and grow them to perfection.George knows from Heuchera, having trialed 83 varieties side by side (the exhaustive results are in this pdf). “I say to people, ‘I’m doing Consumer Reports for plants,'” he explains. Though there are countless varieties on the market, many are duplicative in appearance or just not distinctive. “I can honestly say that when it

In the early 1990s, when I was working on a book called “The Natural Habitat Garden” with my friend Ken Druse, we traveled the country interviewing native-plant enthusiasts and photographing their gardens. One memorable stop was the home of Mrs. Lammot du Pont Copeland, outside Wilmington, which today is the botanic garden called Mt. Cuba Center, with more than 50 acres of display gardens on more than 500 acres of natural land.I’d never seen native terrestrial orchids before, or the vivid red and yellow wildflower called Spigelia marilandica anywhere, and that day I learned that some discerning and forward-thinking experts such as Mt. Cuba’s first horticulture director, the great Dick Lighty, were already busy selecting “better” forms of native plants for garden use–a trend that has accelerated and become one of the hottest areas of contemp

We’ve talked before on the show about your past trials of other native plants like Baptisia and Heuchera—and native plants are the mission of Mt. Cuba, which is both a garden for visiting and a research center, right?A. Mt. Cuba Center is actually a former du Pont family estate, the Copeland family estate, and they left their estate to become a public garden. What kind of sets us apart from others in the area is that we focus on native plants. We broadly define our nativity region as the Eastern United States.We do a lot of work promoting plants in a display capacity in the gardens itself, and then we also do research like what I do, trying to help

George Coombs managed the Trial Gardens at Mt. Cuba Center native plant garden and research facility in Delaware. In past conversations, George–who in 2019 was promoted to Mt. Cuba’s Director of Horticulture–has helped me make our way through the daunting selections of Heuchera, Monarda, and Baptisia. George and the trial garden team spent three years evaluating 94 different sun-loving selections of Phlox for eye and butterfly appeal and mildew resistance, plus 43 shade-garden choices, too.  Read along as you listen to the February 26, 2018 edition of my public-radio show and podcast using the player below.

Plus, various butterflies use the foliage as their host plant, and bumblebees find the flowers particularly delightful.George Coombs of Mt. Cuba Center in Delaware is one gardener who has not overlooked baptisias, the so-called false indigos, at all.In fact, he has planted and evaluated 46 selections with genetics from 11 different species as part of the trials conducted at Mt. Cuba from 2012 to 2015, and when the full-color report on those side-by-side assessments arrived recently in my mailbox fro

Learn from him when and how to plant them for best results; which varieties stand up to wind and rain best without toppling; how to have a peony season that extends to about seven weeks of beauty, and even when to cut flowers and prepare them to be longest-lasting in a vase (that answer may surprise you). And yes, he’ll explain why those ants like peony buds so much. Read along as you listen to the June 10, 2019 edition of my public-radio show and podcast using the player below.

It got me thinking formal.The Mt. Cuba press release described the redesign of a formal garden originally created in the 1940s to complement the estate’s impressive Colonial Revival home (one that’s now on the National Register).  And the photos looked inspired by a proper English-style mixed border–except the headline and captions all made it clear: the new plant palette is n

We all want groundcovers to do weed-suppressing duty and tie the garden together aesthetically, but the wrong choices can definitely backfire. Native groundcovers are a smarter alternative that will provide those and other benefits and they’re today’s topic.I talked about making the change is Duncan Himmelman of Mt. Cuba Center, the noted native plant garden and research center in Delaware, where he’s the education manager. A course on native groundcovers taught by Duncan—from low perennials like heucheras or tiarella (above) or sedges to shr

Duncan Himmelman, currently the education manager at Mt. Cuba Center, a renown native plant garden and research site, earned his doctorate in ornamental horticulture at Cornell before teaching college for 24 years. He’s also managed a large private estate and designed gardens for private clients, so he knows from weeds and weeding.We talked about weed ID, and why it matters to know a weed’s name and life cycle (that’s chickweed, Stellaria media, a winter annual, above; photo from Wikimedia). We also discussed removal tactics and why skipping the chemicals makes the best sense, and more.Read along as you listen to the November 2, 2020 edition of my public

But how good are all these new cultivars as garden plants? And maybe more important, how good are they at supporting pollinators? The native plant experts at Mt. Cuba Center in Delaware have just released a report on the results of a multi-year trial of Echinacea, and their insights are our topic today.Today’s guest, Sam Hoadley, is manager of horticultural research at Mt. Cuba Center, a longtime native plant garden and research site, where he trialed 75 different Echinacea. Before joining Mt. Cuba, Sam was lead horticulturist for Longwood Garden’s h
