51: The Orchid, Serome Hamlin's Enchanted Gardens, How to Prune an Oak Leaf Hydrangea 05.02.2022

I couldn't resist paying homage to an outdoor plant that made me so happy while I was hanging out all smug in Horticultural zone 10 for a few weeks, but I will be happy to get back to my zone 7B indoor orchids.

49: The Ficus, Julie Hart of Tasmania, Pruning Macrophylla Hydrangeas 22.01.2022

I had no idea that the Ficus incorporates so many different type of plant (including epiphytes) and is even the name for a type of sea snail found near Singapore. But in the episode I concentrate on plants-- house plants mostly. I have a chat with the delightful Nanny Noo (Julie Hart) of Launceston, Tasmania and before going into the normal gardening topic of pruning Hydrangea macrophylla (which y...

44: Amaryllis, Ellen Zachos of The Backyard Forager, bulbs in pots 18.12.2021

Besides learning that the Amaryllis is actually, in most cases a Hippeastrum, you will hear my rationalization for enjoying those bulbs without trying to get them to re-bloom the next year. I chat with Ellen Zachos about foraging for food (and cocktail enhancements!) in your own backyard: why you would even want to do this, and how to do it safely. Tips about planting spring bulbs in pots and thou...

39: Fall Fiesta Sugar Maple, Erin the Impatient Gardener, planting a tree and more 13.11.2021

I highly recommend you get your fall fiesta from the native Acer saccharum instead of that other colorful thing that is taking over our native forests: Burning Bush or Eonymus alatus.

And I take you through some basics of perennials division, planting a tree, and what to do wit...

37: Ajania pacifica, Sister Sue Ann on bulbs, moving peonies and more 06.11.2021

After a scintillating fox update (if you follow me on Instagram, you know that's a thing) I choose the Silver and Gold, or Ajania pacifica as the Plant of the Week. Sister Sue and I delve deep into how to plant bulbs, and maybe what bulbs to plant, and I deal with questions on Vinca minor, moving peonies and what to do in the garden this week. Shout out to the Home Grown National Park-- $20 for 20...

36: Oak Leaf Hydrangea, Lizzie Fox of the Rose Press Garden, Brooklyn Bridge Park 30.10.2021

The color that most Oak Leaf Hydrangea leaves turn this time of year reminds me of a fine red wine sipped by the fire, so that means it has to be the Plant of the Week. You are going to be charmed by Lizzie Fox , a young woman in Norwich, England, who is turning seed shopping a shiny, beautiful and new direction, and other details include pruning hydrangeas, watering chores (at this time of year?...

35: Japanese and native American Anemones, Christy Wilhelmi, more on compost! 23.10.2021

Because we haven't featured a native Plant of the Week for a while, and because I could not ignore the Honorine Jobert in my yard, we double dip with both the Japanese anemone and the Anemone virginiana, which, although it isn't blooming now like our Asian friend, blooms in spring and is pretty too! Christy Wilhelmi and I flit around the garden topics, touching down on compost, no dig gardening, m...

33: The Chrysanthemum, fall gardening thoughts with Sister Sue Ann, and thoughts on noisy blowers 09.10.2021

This week we get all pumpkin spicy autumnal with the mum as our POW, some dried hydrangea and dahlias cutting tips, and a long chat with sister Sue Ann about what is happening in her garden, mine, and others of which we are jealous. Timely information about bringing indoor plants back in NOW is a great preview for next week's visit with Marianne Wilburn. 

33: Asian Jumping Worms, Zinnias, and Gregory Britt 02.10.2021

Gregory Britt, "That Nice Guy Who Creates Epic Floral Artistry" joins me for a wandering (literally, as I chase him around the studio with my lame microphone and we battle traffic noise) chat about flowers, gardening, and house plants. I have collected good basic (read: for idiots like me) info on the Asian Jumping Worm and the classic Zinnia is the Plant of the Week!
