It’s spring…flowers are emerging and so are the podcasts. Here’s the first of our eight episodes for the season. The theme this week is “Spring Cleaning” and it’s the wide world of weeds. The podcasts are now hosted on i-Tunes, so I can follow you anywhere you go. Just sayin’.
I’m trying to get some listener questions “on air” as it were, so if you have a burning desire to be on a podcast with me, just drop an email to firstname.lastname@example.org and let me know.
I’ve been AWOL this week with a massive research project (more on that next week). But I want to usher 2011 out with my last podcast, appropriately entitled “Resolutions.”
Hope you enjoy it – have a safe and happy new year!
Gardeners are spending more time indoors than out this time of year, so this week’s podcast features an interview with Dr. Rita Hummel. Dr. Hummel teaches a course on interior plantscaping and is also an expert on plant cold hardiness. Here she combines both areas to explain chilling injury on tropical houseplants.
The greenhouse that this plant lives in lost its heating system and is now showing signs of chilling injury.
Comparison of three leaves on the same plant. In the back is a healthy leaf; in the middle is one with initial signs of damage (bronzed areas on leaf), and in front is a severely injured leaf that has already begun to turn yellow.
The podcast also has a couple of interesting news items on compost safety and treating disease with thermotherapy, and finally a discussion about the wisdom of wound sealants.
Enjoy! And keep warm!
The next podcast is up and running for your listening pleasure. I’ve got an interview with Dr. Gary Chastagner, WSU’s Christmas tree expert. He’ll tell you about his latest research and share some tips for keeping your tree happy and your carpet needle-free.
Here are some photos from Gary’s “dungeon” where he’s been comparing needle retention with some new promising conifer species from other parts of the world:
In the dungeon with Gary Chastagner
What dungeon would be complete without a rack or two?
I know which one I’d choose…
If you are really hard core, here’s a link to some of Dr. Chastagner’s research. Just look for the Christmas tree heading and click on it.
I got so excited about our live tree hunt (posted yesterday) that I forgot to put up the podcast! So here it is…Winter Winners.
The interview of the week is at the Washington Park Arboretum in Seattle, with Director Dr. Sarah Reichard. We visited the Winter Garden, where she (wearing her taxonomy hat) picked out her favorite plants. They include paperbark maple (Acer griseum)…
(the sun shining through the bark is incredible)
…and contorted hazelnut (Corylus contorta)…
(hard to see, but love the bare twigs)
…and Garrya x issaquahensis…
(these most amazing catkins get longer and longer)
…and Rhododendron strigillosum with the coolest bristly petioles:
(a very tidy rhododendron)
As always, I would love questions and suggestions for future podcasts!
We’re popping out the podcasts like crazy! This week the theme is “Gifts that keep on giving.” Along with the news tidbits and myth busting, I had a lot of fun interviewing shoppers at some Seattle nurseries. I started out with two relatively simple questions about gardening gifts, and you’ll enjoy hearing the responses. There are some great ideas out there!
As always, feel free to let me know if you’ve got suggestions for future topics. We’re halfway through Season 2, and I’m collecting spring ideas for Season 3.
While our US readers enjoy the Thanksgiving holidays, you can all enjoy this week’s podcast, entitled “Leftovers.” We discuss good leftovers (transforming orange peels into useful chemicals) and bad leftovers (fertilizer runoff), and then take a trip to an innovative company (Recovery 1) that recycles building demolition materials:
Huge piles of wood, wallboard, and other materials left over from demolition.
The initial sorting process – metals like nails are pulled out, wallboard is separated into components, and wood continues…
…to the end, where it’s chipped into different sizes to create a recycled mulch product.
Discarded carpet awaits separation into components that might eventually be used to help mop up marine oil spills.
All surface water from the site ends up in this detention pond, where it’s filtered and tested before it’s released to the environment.
Be sure to let me know if you have questions about the podcast, or even better if you have ideas for future topics and/or interviewees.
