Cold Tolerant Succulents. Plants for a School Garden. Pepper Seed Germination Tips.

ABOVE: Tips for Germinating Pepper Seeds in Less Than Two or Three Weeks Episode 161 of the Garden Basics with Farmer Fred podcast delved into two popular issues: tips for choosing the easiest to grow succulents; and, the best plants and themes for a school/home school garden. In this newsletter, we expand on those two topics, plus a bonus podcast (above) with information on getting pepper seeds to germinate quicker. More tips are included at the bottom of this “Beyond the Garden Basics” newsletter. There’s no need to wait two or three weeks to see those pepper seeds begin to sprout! (Usually. Your results may vary. All gardening is local.) Succulents That Can Take a Bit More Cold Weather For gardeners just starting off their succulent garden, either indoors or outdoors, our interview with Robin Stockwell in Episode 161 has a lot of good advice on choosing and planting these unthirsty, beautiful blooming plants, which thrive in warmer climates. And what’s true for all plants is true for succulents: choose the right plant for the right place. The beauty of succulents: they do well, indoors, too. In the right sized pot, with the correct soil mix, of course. Robin gets into those details in Episode 161 . But what about for gardeners in colder climates? Are there any succulents that can take a freeze better than others? Robin Stockwell notes those in his beautiful, excellent book, “ Succulents: The Ultimate Guide to Choosing, Designing, and Growing 200 Easy-Care Plants ”. Unfortunately, it may be difficult finding this book, even though it is only five years old. Check with your favorite used book sources for a possible copy, or Amazon . Stockwell highlights those succulents that can tolerate outdoor temperatures at or below freezing: Delosperma (many). Hardy to 20 degrees. Sedum hispanicum . Hardy to 20 degrees. Sedum rupestre ‘Angelina’. Hardy to 20 degrees. Sedum rupestre ‘Blue Spruce’. Hardy to 20 degrees. Sempervivum (many) . Hardy to 25 degrees. Another strategy for growing tender succulents that may be a bit chilly in the outdoors in the winter where you live: grow them in pots , and move them to a warmer location (against a south or west facing wall, preferably with a cover) or…indoors. Starting a School Garden? Tips for the Home School garden, as well. In Episode 161 of Garden Basics , we tackled a question from a school superintendent who wants to start an elementary school garden. Our in-house school marm, Debbie Flower, has first hand experience with this, and offered up plenty of good tips, including making sure that the plant selections can overlap beyond botany lessons to other scientific endeavors in the classroom, such as choosing plants that attract beneficial insects and pollinators to control pests; and, choosing plants that may reflect on the Native-American culture of the area: which plants did the first residents consume and use? Homeschool instructors, as well, can pick up a lot of good tips for providing a well-rounded education, just by growing the right plants, especially native plants. Give it a listen . And if you are interested in attracting bees and other pollinators to your garden, here’s a list of plants that can provide year-round bee attraction in California’s interior. For all zones, check out these regional plant recommendations of the Xerces Society for attracting bees, butterflies, hummingbirds and other pollinators to your garden . More Tips for Germinating Pepper Seeds For many home vegetable gardeners, growing peppers from seed can be an excruciating experience. January is the time for many in USDA Zones 7, 8, and 9 to start those seeds. Colder climates can wait another month or so. Still, it can take 12 weeks or more from the time of planting a pepper seed to the point where it is vigorous enough to be taken outdoors. However, there are some tips for speeding up that process. Home gardeners who grow their tomatoes from seed usually get fairly quick results after sowing the seeds indoors. Given the right germinating conditions - a soilless planting mix, good drainage, plenty of light, plenty of warmth - tomato seeds can pop up in 8-10 days. Pepper seeds are a different story. Why is it some peppers can take weeks to germinate? "The important thing in getting your (pepper) seeds to germinate is to keep them warm – the soil temperature should be in the 80's", says Renee Shepherd of Renee's Garden , a popular seed catalog based in Felton, California. "Germination is very much related to even moisture and warm temperatures. You should see germination within 2 to 3 weeks if it's warm enough. I strongly suggest using bottom heat to achieve the warmth the seeds need – most good nurseries carry electric seed starting mats which will keep your seed soil at the right temperature in order for the pepper seeds to sprout. A local mail order source is Peaceful Valley Farm Supply ." For those who want to comparison shop, another source for heating mats for your pepper seeds: Amazon . Another trick that some gardeners employ is soaking the pepper seed for awhile - even overnight - before sowing, in order to soften the seed coat. The value of that is open to debate. "I have never heard of soaking pepper seeds overnight and have never done it in 20 years of running a trial garden," says Shepherd. On the other hand, Professor Debbie Flower, formerly of the American River College Horticulture Department, sees the benefits of some "immersion therapy" for pepper seeds. "We soaked our pepper seeds in hydrogen peroxide for 10 minutes," explains Flower. "That's not enough time to scarify (soften or break the seedcoat), or even get them soaked, but enough to kill exterior diseases." Many sweet pepper varieties will show their initial leaves about two weeks after planting the seeds. But some varieties of peppers take longer to pop up than others. "The hot pepper varieties take longer to germinate, some to three weeks," says Flower. But if you are experimenting with the really hot pepper varieties, such as the Bhut Jolokia (Ghost Pepper), it could take up to four months, says the Trade Winds Fruit website: "Chinense species (e.g. Habanero's) generally take longer to germinate than most common peppers. Keep soil warm to very warm (75-90F) for better germination. Do not use acidic soil. Some Chinense peppers, in particular Bhut Jolokia, Naga Morich and related peppers are very slow to germinate, averaging 1-4 months germination time." By the way, if you are growing the Bhut Jolokia...you're playing with fire. The Ghost Pepper is rated at 850,000 Scoville units of heat. For comparison, the habanero rates 200,000; the Jalapeno is 5,000; the Anaheim equals 1,000. And sweet bell peppers? 0. This is as hot as I can stand. The Inferno: 4,000 Scoville Heat Units Another factor that can determine the rate of germination of pepper seeds: the pH of your seed starting mix. One of the most common ingredients in most seed starting mixes is peat moss, which is highly acidic, with a pH around 4.0. Pepper heads, including the Horticulture students at American River College, have found quicker germination when Coir (coconut fiber) is substituted for peat moss. Coir has a closer-to-neutral pH: around 6.5. The tests at American River College bear this out after trying Coir in their pepper seed soil mix. "We've had the best germination of peppers ever!" says Flower. And don't be in a rush to set them out in their permanent garden home. "Pepper seedlings need to be grown out until they have at least several sets of true leaves, and it is at least 55° at night before you plant them out," explains Renee Shepherd. "And they will need a little time to get used to being outdoors, as well." Here in the Central Valley of California, that would be around mid-May. Be patient. Now, for the MORE tips portion: Since first posted years ago, this Farmer Fred Rant Blog page has received a lot of attention. The beauty of that...lots of pepper growers have chimed in about their preferred methods for growing peppers.One method that was seconded by many: germinate your pepper seeds in between two moist paper towels in a room that is between 70 and 80 degrees. For many, that room might be the kitchen or bathroom. When the "tails" appear after about 6 or 7 days (the tails, by the way, are the emerging roots), gently transplant them into a moist, seed starting mix, preferably one that uses the more neutral coir instead of the lower pH peat moss. Or, make your own. My preferred home mix consists of equal parts coir, perlite and fine compost. The improvements I would make to that germination suggestion? Use coffee filters instead of paper towels. That way, the emerging root doesn't get tangled, as happens when using fibrous paper towels. Pulling out germinated seeds from paper towels may be hazardous to their health.Also, to insure a warm environment, here's something you could do in just about any indoor room: place the moist coffee filters, containing the pepper seeds, inside a glass baking pan. Place that on top of a germination mat. Cover the baking pan with plastic wrap to keep it warmer. I tried this at home, and the pepper seeds germinated with six days.
