Beyond the Garden Basics Podcast

In today’s podcast, Sacramento County Master Gardener and vegetable expert Gail Pothour explains how to transition garden beds and raised beds from warm-season crops to cool-season plantings. We talk about clearing out tomatoes, peppers, squash, cucumbers, and melons at the end of summer: should you pull out the plant or cut it off at the soil line? It depends. Gail will explain, emphasizing the importance of checking the roots of summer garden plants if they were victims of pests or disease. Gail mentions the advantages of adding compost and lightly working it into the soil rather than doing heavy tilling.

She also discusses winter cover crops such as mustard mix, crimson clover, and soil-builder blends of cover crops, along with how and when to cut them down so they improve the soil.

Here are the main points from the podcast:

* Before you rip out summer crops and jump straight into fall planting, take a beat and deal with your soil first. It makes a real difference.

* When you pull spent tomatoes and squash, check a cross section of the main stem for browning. That’s a sign of fusarium wilt, and it means the disease could spread to your other beds.

* Pull the roots all the way out instead of cutting plants at soil level. Yes, leaving roots to decompose feeds beneficial bacteria, but you need to see the roots to check for root knot nematodes. Gail’s team found nematodes in a bed that never had that problem before.

* Skip granular fertilizers for fall planting. It’s slow release, and cool season crops need something that acts fast. A liquid feed, such as fish emulsion or kelp, works better. And honestly, you might not even need it. Let the plant tell you if it’s hungry through the yellowing leaves.

* Work a couple inches of compost into the bed gently. No tilling needed. Just slide a garden fork in (a broadfork is ideal), rock it a bit, and let the compost filter down naturally so you’re not disturbing the soil structure too much. That helps preserve the existing beneficial soil microbiology.

* Cover crops are a smart move if you’re not planting edibles in every bed this winter. Try a mustard mix (it actually helps suppress nematode populations), crimson clover for nitrogen fixing, or a soil builder blend of oats, vetch, peas and bell beans.

* Timing matters with cover crops. Cut them down while they’re flowering. That’s when the nitrogen benefit to your soil is highest. Let them go to seed and most of that nitrogen gets diverted into the beans or pods instead.

* Fine cover crops like mustard and crimson clover can be left right on the soil as mulch. Woodier ones like bell beans and the soil builder mix need to be chopped up first, or they’ll take forever to break down.

* With a wet winter predicted, mulch is doing double duty. It protects against erosion and it cushions the soil from compaction when heavy rain pounds down on bare dirt.

* Only use disease-free plant material for mulch or compost. If you’re dealing with powdery mildew, fusarium, or nematodes, that spent plant material needs to go in the trash, not back into your growing space.

* Check thick foliage plants like tomatoes for pest eggs before composting them. Leaf-footed bug eggs and similar pests will happily overwinter in your compost pile and come right back to suck on your plants next season.

* Great low-maintenance winter crops for milder zones include lettuce, peas, fava beans, beets, carrots, bok choy, cabbage, kohlrabi, and brussels sprouts.

* Tokyo Bekana Chinese cabbage is worth growing even though it’s technically a brassica. It’s soft and lime green with a thin leaf, so it eats more like lettuce than cabbage.

* Soak pea seeds overnight in tepid water before planting to help speed germination.

* Beet and chard seeds benefit from a shorter (2-4 hours) soaking in water too. That soaking helps break down those seeds’ natural germination inhibitor, speeding the germination process.

* Carrot seeds are notoriously slow and tricky, sometimes taking three weeks to germinate. Cover them lightly with compost, lay a thin row cover or burlap on top, and keep the bed consistently moist. If carrot seeds dry out mid-germination, they die. More info here about growing carrots.

* Soaking carrot seeds for a few hours before planting can speed things up considerably. Some gardeners even rub the seeds on a sieve to rough up the coating a bit, which can help too.

* Don’t skip watering just because it’s cooler out. The soil needs to be moist before you plant, and consistently moist (not soggy) afterward, especially for slow germinators like carrots.

* Winter gardens are lower maintenance than summer ones, but they’re not zero maintenance. Keep an eye out for snails, slugs, earwigs, whiteflies, aphids, cabbage loopers, harlequin bugs, and bagrada bugs. A little monitoring goes a long way.

Getting the Soil Ready for Cool Season Plants

In today’s podcast, Master Gardener and vegetable expert Gail Pothour talks about cool season greens to grow in your backyard garden during the fall and winter. There’s a human-corrected transcript at the bottom of this newsletter. Among the main points in our conversation:

* Cool season vegetable gardening works especially well in USDA zones 7, 8, 9, and 10; but in colder areas you can grow food nearly year round if you plan for it.

* Late summer into early fall is the time to pull tired summer crops, work in some compost and fertilizer, and get cool season seeds or transplants in the ground while the soil is still warm.

* Most cool season crops mature fast, often in 40 to 60 days, so you can have a real harvest within about two months.

* A cold frame, basically a raised bed with a hinged translucent lid, protects plants from frost and heavy rain, and doubles as an insect barrier when you stretch screen across the open top during the day. A must for colder climates.

* Floating row covers are one of the most useful tools this time of year. It keeps cabbage loopers and imported cabbage worms from laying eggs on brassicas like kale, broccoli, cauliflower and radishes, and it can even help slow down snails and slugs.

* Row covers also help slow-to-germinate seeds like carrots and beets by keeping the soil consistently moist while they sprout.

* Beginners are usually better off buying transplants than starting from seed, since crops like lettuce and carrots can be tricky to germinate from seed.

* When buying transplants, choose smaller, sturdy, healthy looking plants rather than tall or root-bound ones, since cool season crops don’t love having their roots disturbed.

* If you can’t plant right away, move six pack transplants into their own four inch pots with fresh potting soil first. It gives them a chance to build stronger roots before they go in the ground.

* For lettuce, stick with loose leaf types like romaine and butter lettuce rather than Iceberg, which struggles to head up properly in home gardens in the warmer areas of USDA Zone 9. Favorites mentioned include Salanova red butter, Pomegranate Crunch, Lola Rossa and the heirloom Forellenschluss (also known as “speckled trout” or “flashy trout back”).

* Swiss chard, especially “Bright Lights” with its multicolored stems, is easy to grow, good looking enough for a flower bed, and often overwinters into the next summer.

* For kale, go with edible types like Lacinato (dinosaur kale), Tuscan baby leaf, Red Bor, and Red Russian rather than the tough, purely ornamental kales.

* Asian greens like Pak Choi and Bok Choy, including a fast growing All America Selection called Asian Delight, are quick to harvest and tend to have fewer pest problems because they’re in the ground for such a short time.

* Once brassicas bolt in late winter, the flowers are a magnet for bees and other beneficial insects, and the young flower shoots on kale can be cut and cooked just like broccolini.

* For spinach, look for less crinkled varieties like Tyee, which are easier to clean, and treat it as a fast, short lived crop worth succession planting rather than one you let linger in the garden.

Cool Season Garden PLANNING Time is Here

In today’s podcast, we talk with Sacramento County Master Gardener Michael Stinson about the when, how and why of pruning blackberry vines. Don’t want to listen? Here’s a summary. A complete transcript is at the bottom of this newsletter.

Pruning Blackberries: Key Points

From a conversation with Sacramento County Master Gardener Michael Stinson

• Blackberry plants are perennials that can live 15 to 20 years, but each individual cane only last around two seasons, with a notable exception.

• First year canes are called primocanes. Second year canes, the ones that flower and fruit, are floricanes. Fall pruning is all about removing the floricanes.

Pruning Blackberries

We tackle two prickly topics: the spiky, caltrop-like seed balls of puncturevine weed and the “sputniks” of liquidambar (sweet gum) trees. Yes, those sharply pointed spheres that fly in the autumn breeze do resemble Eisenhower-era, low-earth orbiting Russian weapons of no destruction.

Controlling Puncturevine Weed and Liquidambar Tree Seeds

Collecting, Storing and Using Home-Saved Tomato Seeds

If you want to save seeds of a particular tomato variety, remember that many varieties are hybrids; they may not necessarily come back with the same traits as the tomato you enjoyed last season. According to Penn State Extension, the result of these crosses usually only lasts one generation, so the seeds harvested from hybrids may produce disappointing results.

Or, may not be a disappointment. Tomato flowers are primarily wind-pollinated. So, those plants grown in isolation or covered with insect netting during their flowering period may provide satisfactory results. Experiment! One tip: note the tastiest varieties in your garden right now, in September. Save those seeds. Then, next year, put the plant that germinates far away from your other tomato varieties.

Open pollinated or heirloom tomato seeds are fine for saving, as long as they are grown 10-30 feet away from any other varieties. For best results: save the seeds from tomatoes that are overly ripe; rinse off as much of the flesh and protective gelatinous coating from the seeds as is possible. Then, soak the seeds in a jar of water for a couple of days to remove the rest of the coating. The seeds will sink to the bottom, the gel will float. Discard the gel, remove the seeds and let dry on a paper towel. Then, store in an airtight container in a cool, dry location.

Tomato seed saving techniques can vary. Here’s a sampling of methods from across the country.

Saving Homegrown Tomato Seeds...and more about Tomatoes!

“Of all flowers, methinks rose is best”. Shakespeare said that. He lived in Stratford-upon-Avon, about halfway between London and Birmingham, England. However, the roses he saw 600 years ago never endured 100 degree heat…until recently.

Although roses were found originally in Central Asia, they spread quickly throughout the Northern Hemisphere between the 12th and 18th centuries.

Those old roses wouldn’t stand a chance in the heatwaves of the 21st century, succumbing to scorched flowers, leaves, and buds…as well as dying off due to a lack of regular watering in drought-effected areas.

Of course, hybridization of roses in the 19th, 20th and 21st centuries has created varieties that can withstand a number of modern ailments, including air pollution.

So, what are the modern roses that can take the heat, when temperatures hit 100 degrees for several days in a row? What are the traits of a heat-tolerant rose?

Master Rosarian Debbie Arrington of the Sacramento Rose Society (and the Sacramento Digs Gardening blog) enumerated several in the podcast at the top of this page. Sacramento (City Motto: “At Least It’s a Dry Heat”) is no stranger to prolonged, triple digit heat waves, which can occur anytime from May through September. So, the area is a good testing ground for roses that maintain their color, health and vigor throughout spring, summer - and sometimes fall - heatwaves. One trait many of these have in common: these rose bushes produce light-colored blooms of white, pink or yellow. Most red roses, Arrington explains, absorb more of the heat, and will be among the first to scorch. Sorry about that, Bobby Darin.

Among the roses on Debbie Arrington’s list of heat-tolerant roses:

Heat-Tolerant Roses

Blossom end rot is generally considered the most common tomato problem for backyard gardeners in the US. It causes a dark, sunken, leathery spot on the bottom of the fruit, and it’s usually caused by inconsistent watering (not actually a soil calcium deficiency in most cases) that disrupts calcium uptake in the plant.

For those of you at home keeping score, close runners-up are early blight and septoria leaf spot, both fungal diseases that cause yellowing and spotted leaves, especially in humid climates.

The big difference between blossom end rot and all those runner-up problems? Blossom end rot is an abiotic disorder, not something you can blame on a disease or an insect (“Abiotic disorder” is plant nerd talk for “it’s the gardener’s fault”).

Dealing with Tomato Blossom End Rot

Today’s podcast and newsletter of Beyond the Garden Basics is something a bit different, but very important: what to do around your home, both inside and outside, if a wildfire is in the area, and you have a few hours before an evacuation becomes mandatory.

That was the topic in a Youtube video presented by Todd Lando, a battalion chief and wildfire mitigation specialist for the Central Marin Fire District. Marin County is in northern california, just north of San Francisco, a bucolic area with hills, mountains and forests abutting the Pacific Ocean. As you might imagine, especially with its proximity to San Francisco, it is one of the more heavily populated areas that can be described as the urban-wildland interface, where suburbia meets a very fire prone area. More information can be found at the website fire safe marin dot org.

Among the practical tips that Lando discusses in the video include what should be done to prepare if a wildfire is getting to be an imminent situation. Of course, if you hear the order to evacuate immediately, you do want to leave immediately. 

Here’s a summary of his advice.

What To Do When a Wildfire Approaches Your Home

Before we attempt to rid our zinnias of powdery mildew disease, let’s first hear from Debbie Flower, who has plenty of zinnia growing tips for us in today’s podcast. Here’s the quick summary of our chat, which included how to cut outdoor flowers for indoor use. A complete transcript can be found at the bottom of today’s newletter.

* Plant zinnias in full sun. They’re heat and drought tolerant, and bloom most prolifically when days are under 12 hours (expect peak blooms in fall). Planting zinnias where they get full sun, with proper spacing (18”-24” apart) is also great cultural controls for thwarting a powdery mildew breakout.

* Succession-plant every two weeks through early summer for a continuous supply of cut flowers. This is also a good powdery mildew control strategy. Trash (don’t compost) heavily infected zinnia plants. Plant new seeds where you want them to grow!

* Wait until soil is at least 70°F to sow seeds. Germination requires warm soil.

* Cover seeds lightly with vermiculite. It marks where seeds are planted and retains moisture during germination.

* Don’t plant two seeds per spot if using fresh seed. One is enough; double-sowing is only needed to compensate for old/marginal seed.

* Avoid overhead irrigation. It spots flowers and splashes soil onto foliage, promoting disease. Use drip or soaker hoses instead. Another powdery mildew prevention strategy.

* Space plants so they never touch neighboring plants. Good airflow prevents powdery mildew and Alternaria leaf blight.

* Transplant zinnias early. Don’t let nursery starts become root-bound; roots disturbed at that stage cause double-flowered varieties to revert to singles. And don’t buy zinnia plants with powdery white substances on the leaves!

* Pinch young plants (at 4 nodes, remove 1–2) for a bushy, branched plant with more but shorter stems. Skip pinching if you want tall stems for large bouquets.

* Cut flowers in the morning. Plants move carbohydrates (food) into flowers overnight, so blooms are fullest and will last longest when cut early.

* Cut stems at a node, leaving at least one axil bud on the remaining stem. That bud becomes the next flower stalk. More axil buds left = more future stems; fewer = longer current stem.

* Strip leaves that will sit below the waterline and remove side branches from the cut stem before putting in a vase.

* Use floral preservative in vase water, or try hot water. Zinnias last 5–7 days as cut flowers. They will last longer if you do refresher cuts from the bottom of the stem every other day, and add fresh water.

* Use California buckwheat (Eriogonum fasciculatum) as filler in zinnia arrangements. Outdoors, California buckwheat attracts pollinators and has attractive clustered flower heads.

* Support tall varieties in windy or rainy locations with a small tomato/pepper cage. The small cages sold at big-box stores that are useless for tomatoes are well-sized for large zinnias.
