Davis Garden Show, July 29, 2021: Water 50% for ornamentals, 100% for food producers

NEW, EASY WAY to figure out your drought watering! Don shared the research from the University of California, Division of Agriculture and Natural Resources -- Center for Landscape & Urban Horticulture, showing how little water different plants can survive on. Not be happy, but survive.

Lots of info about watering -- trees, shrubs, food plants, and beneficial insects. (Lois asked about making an insect watering hole with wet sand.) One listener writes about her "spider mite apacalypse" and wonders how to keep her melons alive until harvest. 

Why do plants look stressed the third year in the ground when "they did fine last year"? How much water a plant needs depends upon how big it is! So as a young plant grows bigger, you need to give it more water (either water longer or add another sprinkler head).

"Grad Students Help with Soil" is the Davis Enterprise headline; "providing soil diagnosis [texture and pH test] and advice to gardeners" is the service; Saturdays (9:30-11:30) at Davis Farmers Market is the when/where. The service will continue every Saturday thru August 21.


Davis Garden Show, July 22, 2021: Tree roots, watering, and redwoods

Watering in  a drought. Reducing lawn water while keeping your trees alive. Root distribution of trees, "circle watering" strategy.

Coast redwoods in interior California. Many redwoods were planted in Davis years ago; should we add new ones now? What might we substitute for them?

What's wrong with these struggling tomato plants? 

Compacting soils can cause problems.  

"Mulch is for on top, not underground."

And more answers to listeners' questions. Submit yours for inclusion in a future show by emailing Don Shor and Lois Richter at DavisGardenShow@gmail.com

Davis Garden Show July 15 2021, Summer Pruning

Don Shor and Lois Richter talk about July pests -- what 's around now and how to handle things -- and lots about fruit trees -- including broken branches, thinning possibilties, reduced size method, and summer pruning. From that Facebook @ re feeding squirrels -- just don't!

And, of course, we talk about the GLORIOUSLY WONDERFUL WEATHER this week.

Davis Garden Show, July 8, 2021: Heat wave prep

Too many  questions to get to all of them! Come back next week and hear the rest.

Mid-June topics: 

La Niña and rainfall patterns. How to water -- and how not.

What plants want you to do when there's a heat wave. Or, better still, BEFORE one!

Privacy plants -- including avoiding undesired co-habitants (like raccoons and rats)!

Figuring out how/when to plant seeds. Some tips and tricks for certain seeds!

and more ...

Davis Garden Show, July 1, 2021 -- What's a hybrid?

What's a cultivar? What's a hybrid? What's a selection? What's a variety? We get a long answer to a short question about Ceanothus "Concha" and Ceanothus "Ray Hartmann."

Also today we have a discussion of soil pH (probably not the problem in the situation described); the challenges of planting in compost instead of soil; raised planter woes; and  details on local water issues and Davis' good situation. 

Davis Garden Show, June 24, 2021 -- perennials or reseeders?

"See you again next year!"  Today we discuss Don's list of Favorite Summer Perennials, and then we start going through his list of plants that "reseed freely." Both strategies mean we will see the same species in our garden year after year -- with perennials the plant stays in the same place, with re-seeding the species moves around (and sometimes changes color). We also discuss common name confusion, weed cloth over plum tree roots, the city's "Tree Watering" flyer, fruit set on tomatoes and zucchini and their expected yields, and (as usual) the weather and how it is affecting our plants.

Don Shor and Lois Richter are your hosts each week on the Davis Garden Show. To submit a question, email them at DavisGardenShow@gmail.com

Davis Garden Show, June 17, 2021 -- Leave It To Beaver

Did your tree-removal company leave you with a bunch of chips?  Stump grinding can lead to problems with your replacement bushes. How, you ask?  Listen up!  

Don Shor and Lois Richter answer garden questions -- including dealing with drought, lawns, ant farming, ant management, mistaken culprits, and more. Ask your questions by emailing us at DavisGardenShow@gmail.com.

Davis Garden Show, June 10, 2021 -- Herbaceous Fall Flowers

Cool week ahead!  But we still have watering challenges. A few questions (about new plantings and fungus gnats) lead to several important discussions about:

  • Proper planting techniques (why planting trees ONLY with native soil is so important);
  • How roots grow (and get damaged), and how that shows up in a full-grown tree;
  • Home remedies (which have no research done on them and are NOT labelled for pesticide or herbicide use).

A large portion of the show is a discussion of each of Don Shor's 20 Favorite Summer Herbaceous Perennials. An "herbaceous perennial" is a plant that blooms every year but dies down every winter (different from a shrub, bush, or tree). These twenty bloom from the late summer into the fall.  (We only got part way thru before running out of time, so listen to the 24 June show for the rest of the story.)

Davis Garden Show June 03 2021 -- Weather-related Troubles, Easy Vines, Raccoons

Weather-related troubles:  Can X veggie take full sun?  Should we "shade" our tomato plants?  Don says "no".  There's a difference between hot sun on the foliage and the sun-scald of ripening fruit.  Can we keep our trees alive in this year's bone-dry ground?  Signs of stress to look for, and what to do to help while watering most effectively.

Easy vines to cover a fence, wall, trellis  ... including "Cup and saucer vine" (Cobaea scandens) pictured here.

"What's digging up my plants at night?  Not eating them; just digging down underneath and pushing them out."  Raccoons might be digging up the blood meal fertilizer.  What?  They're smelling the blood meal that's UNDERGROUND!!?!  Yep.  On a brighter note, Don is growing tomatoes in a gopher-infested plot -- successfully!

Davis Garden Show, May 27, 2021 -- Questions Answered

Water, water, everywhere! "How much? How often? What happens if I get it wrong?" A large part of today's show is devoted to "basic watering knowledge" and also specific differences for watering in this drought year.

Plus we get LOTS of questions answered! Scorched leaves, geranium budworm, upright evergreen tree suggestions, and more. Lois wanted to know how to tell which plants will die if cut down and which will re-sprout. Don's answer is "It depends. ..." Well, he was a little more specific -- "It depends upon the general structure of that plant."

In all, another fact-filled Davis Garden Show with Don Shor and Lois Richter.

I just discovered you as a replacement for the now-defunct Farmer Fred radio show. I listen to the podcast. It's extremely useful to have timely and local garden coverage again. Thanks! John, Fair Oaks, March 2021

Don and Lois,

Hi! I am back! I was recently given a little beet seedling along with a strawberry plant that I had bought at a yard sale. Before I go on, I want to let you know that this woman did a great job taking care of her plants and the ones she was selling also looked great. However, I forgot to ask her how to take care of the beets. I have never grown them before. Anything you can tell me that I should know about beets? I also would like to know how long these plants can live. I want them to do well. I may not harvest them, but instead enjoy the pretty plants that they are. I am, however harvesting the strawberries.

Don and Lois,

Hi! This might be unusual to ask, but can you tell me how to take care of Hulda Klager Lilacs here in Southern California? I had requested some from the author of a book I read. This author wrote about Hulda Kalger and all she went through in her life and to hybridize plants, especially lilacs. I have two small ones that the author shipped me through the mail along with some seeds. The plants will be possibly the creamy white blooming ones and the seeds pink blooming ones. I have the plants in a nice plastic pot of miracle grow infused potting soil. They are located in part sun and part shade. Anything you can tell me would be so helpful because I want to keep these plants alive. They have great meaning to me.

Thank you so much and it is great to ask you another question.

just wanted to say that Don has been excellent fill-in host and guest for Farmer Fred lately. Esp good was when he and Debbie Flower hosted together but he needed to let Debbie talk a little more. Have not heard the 1 hour show yhet on this Davis station but will start listening now. Its difficult to remember about a Thursday show but i see there's a Saturday rebroadcast, which is great because there is now almost a solid block of gardening shows to listen to on Saturday from 9 AM to 2 PM. Too bad this Davis radio station seems to be a little left of center and anti-business though from what i can see at first glance. Maybe Don can take over FF's show if/when he ever retires.

Don and Lois,

Hi! Miss me? I know I have not written in awhile, but I have been busy. But not too busy to really work on our new back yard garden. And not too busy to listen to the podcasts of your show. I know that tomatos are very popular lately, but do you have any advice on strawberries, such as how much water do strawberries need? Also, how do I keep my cat grass lasting a long time. The lady at the pet shop I bought the cat grass at said that it should last me a long time, but my last pot of cat grass died after about 2 months. It had been slightly chewed on by my neighbors' cat whom I bought it for in the first place. Would this shorten the grasses life expectancy? Your advice, as always, is welcome. Our back yard is turning out beautiful (with some help from Eric and my daughter.)

Looking forward to your next podcast and many more,
Robin in Southern California

What can you do about nutsedge?

HELP

Lois and Don are the BOMB! This is my favorite radio show!

I'm in Sacramento and found this show on Itunes podcasts. I started listening to the DGS podcasts and now I have to listen every week LIVE during lunch hour. It has helped me with my gardening. Because the Sacramento valley is so full of microclimates, there really no replacement for this show for us gardeners here. And the hosts are so delightful and interesting to listen to. I wish Don and Lois would write a book about gardening here! I would buy it! Keep up the good work KDRT!

YAY, Davis Garden Show!!!

What a nice note! Thanks so much for posting it, and thanks for listening!

Don and Lois,

Hi! Thank you so much for answering my African Violet pot question. Your answer was very helpful when I chose a special pot for the varigated African Violet leaf that I had rooted. It looks so cute in the pot with the resievor and wick.

As for my next question, Eric suggested that I ask you if it is ok to prune some plants and trees in wet weather. I do not mean a deluge, but either after a rain storm, between rainstorms, or during a light rain. I do some of my weeding during this weather because the weeds pull up easier, though they do stick to my hands which is not fun.

Thank you for answering my past questions. My ears always perk up when I hear mine and Eric's questions/comments on your show. Very exciting for us both. That is partly why I listen to your podcast first in my lineup of gardening podcasts to listen and watch. The other reason is that your show has the most useful gardening information.

Robin in Southern California

I think it depends upon the species. Some of our California native shrubs (like Ceanothus and Redbud) should NOT be pruned when the cut might get wet. (That's whether in the winter OR in the summer just before the sprinklers come on.) But lots of fruit trees are regularly pruned in winter and then get rained on. I'll ask Don to explain more on our show next week.  -- Lois
