  • Soil Testing with Amy Ellard-Gray

    Soil Testing with Amy Ellard-Gray
    Nov 25 2025
    This week on the podcast, Joanne discusses soil testing with The Hobby Homestead's Amy Ellard-Gray, who grows 75% of her family's fruits and vegetables in her Guelph backyard. About Amy Amy runs The Hobby Homestead in suburban Guelph, where she cultivates over 100 varieties of native plants to support the local ecosystem. Through her YouTube channel, Instagram, website, and in-person consultations, she helps people design and troubleshoot their own food-growing spaces. Her mantra, "growing food in harmony with nature," guides everything she does, from tending soil life to welcoming wildlife into the garden. Topics discussed in this episode: "How much compost is too much?" Amy questioned the popular "just pile on compost" / no-dig approach (e.g., growing directly in municipal compost).After consulting an agronomist, she learned you can overdo compost, especially because compost often has high soluble salts that can stress plants.General rule of thumb from the agronomist: for established beds, about ½ inch (1 cm) of compost as a top-dressing per year is usually enough, but every garden is different. Why test compost and soil? Amy now plans to lab-test her own compost (about $20) for salts and nutrients before using it widely.Lab tests are often similar in price to store-bought kits and usually include a quick consult to interpret results.Soil tests are especially valuable for: New builds or new-to-you properties.High-value plants (e.g., Japanese maples, fruit trees).Chronic problem areas like failing lawns or veggie beds. Home test kits vs lab tests Simple garden-center test kits can be unreliable, especially if old or poorly stored.Nitrogen is hard to test accurately because it changes quickly in the soil; even lab reports often base nitrogen recommendations on plant symptoms, not just numbers.Labs can tailor tests to what you're growing (lawn, ornamentals, vegetables, etc.). pH: the quiet troublemaker Amy's big lesson: pH controls nutrient availability. Low pH can lock up phosphorus.High pH (common in parts of Ontario) ties up iron, manganese, and zinc. Just adding fertilizer won't help if pH is off and plants can't actually access those nutrients.Raising pH with lime is relatively straightforward; lowering pH (for blueberries/azaleas) is hard, requires repeated sulfur, and soil tends to drift back—Amy has nearly given up on blueberries because of this. Choosing soil: bulk vs bags, municipal compost Amy strongly prefers high-quality bulk triple mix from a trusted supplier (often with nutrient analysis available).She's wary of: Bagged soil/compost of unknown origin, age, and quality.Municipal compost giveaways, due to uncertain inputs (treated lawns, herbicides, diseased plants) and inconsistent processing. Leftover bulk soil gets used in pots, extra beds, or stored for future top-ups—she never feels like she has "too much soil." Building and maintaining soil in raised beds & pots Raised beds: start with good triple mix, then top up yearly with a thin layer of compost and mulch (leaves, straw, chop-and-drop).Containers: use potting mix or triple mix plus perlite for drainage; reuse soil but amend and top up rather than dumping it every year.She only uses extra fertilizer (like fish emulsion) when pushing density in containers (e.g., many beets in a small pot). Rotation, disease, and "messy" gardens Classic crop rotation is more critical at farm scale; in small backyards, many diseases are airborne, so simply shifting crops a few feet often doesn't prevent them.Rotation still matters for certain soil-borne diseases (Amy rotated tomatoes after Alternaria collar rot), but it's not the magic solution some make it out to be.Leaving more plant material, leaves, and roots in place supports soil life and natural pest-predator balance, instead of resetting everything with a "clean" fall garden. Amy's message for gardeners Shift your mindset from "feeding the plants" to "feeding the soil."Healthy, living soil is what ultimately feeds healthy, productive plants.

  • Transitioning to Indoor Gardening

    Transitioning to Indoor Gardening
    Nov 11 2025
    This week on Down the Garden Path, Joanne shares her passion for indoor gardening with practical winter houseplant care tips and a reminder that there's always something new to learn and grow. Topics discussed: 1. From Annuals to Houseplants It's time to turn your attention to houseplants as gardening shifts indoors.Don't rush out to buy new plants: friends and family often have extras or cuttings to share. 2. Winter Care Basics During shorter days and lower light levels, houseplants slow down their growth.Do not fertilize in winter; they're not actively growing.Keep watering moderately: it's better to underwater than overwater.Use a moisture meter or finger test to check the soil before watering. 3. Refresh and Repot Check plants for dryness, dust, or signs they've outgrown their pots.Wipe dusty leaves with a damp cloth to help them absorb light.Consider repotting if roots are showing through the drainage holes.Use potting soil, not garden soil, and choose soil types suited to plant varieties (succulents, orchids, etc.).Avoid decorative pots without drainage for valuable plants. 4. Easy Propagation and Gift Ideas Take cuttings from plants like pothos, philodendron, and peperomia.Start them in water using clear containers to monitor root growth.Plant swaps are a fun and inexpensive way to expand your collection.Propagated plants make meaningful, affordable holiday gifts. 5. Learning and Experimenting Joanne shares her experiences with low-maintenance plants (snake plant, ZZ plant, pothos).Recently inspired to try more demanding varieties like Alocasia.Discusses challenges like insect issues and learning about proper soil mixes. 6. The Joy and Benefits of Houseplants Houseplants add life, colour, and calm to indoor spaces during the winter.Handling soil can improve mood and mental health.Every room benefits from having at least one plant.Notes the outdated NASA air-purifying study—plants don't clean air significantly but do add humidity and beauty.

  • Mythic Plants with Ellen Zachos

    Mythic Plants with Ellen Zachos
    Nov 4 2025
    This week, Joanne welcomes Ellen Zachos, author of 11 books on plants, including her latest, Mythic Plants: Potions and Poisons from the Gardens of the Gods. About Ellen A Harvard graduate, Ellen's first career was on Broadway (Les Miz), but the gift of a peace lily on opening night opened her eyes to the wonderful world of plants. Ellen taught at the New York Botanical Garden for many years and also served as Coordinator of the Gardening Department in Continuing Ed, before moving to Santa Fe, NM. She was named a Great American Gardener by the Epcot Flower and Garden Festival. Her 11th book, Mythic Plants: Potions & Poisons from the Gardens of the Gods, was published this year. Inspiration & Research Grew from Ellen's Greek heritage and lifelong love of mythology and plants. Greek mythology felt personally significant; she wasn't drawn to Norse or Indian myths. Extensive research across historical texts; citations couldn't fit in the print book, but are available online. Plant Stories & Mythology Connections Nepenthe (Poppy): In Homer's Odyssey, Helen of Troy prepared Nepenthe—an "anti-sorrow" drink of wine and opium poppy. Calmed grief temporarily. Linnaeus later named the tropical pitcher plant Nepenthes after this myth, believing its beauty could lift sorrow. Moly (Snowdrop): Hermes gave Odysseus "Moly" to protect him from Circe's spells. Described as a plant with black roots and white flowers—likely the snowdrop (Galanthus). Contains galantamine, which counters hallucinations—aligning with the myth's antidote effect. Modern research explores galantamine for Alzheimer's treatment. Fig: Valued food in ancient Greece, consumed fresh or dried before refrigeration existed. Special laws governed fig harvesting; penalties for theft were severe. Ancient figs required complex pollination (caprification). Some myths surrounding figs are notably "saucy." Pine Tree: Associated with violent origin myths, but also practical uses. Pine nuts were a staple food; pine resin sealed wine vessels, the origin of Retsina wine. Modern Retsina has a milder pine flavour, enjoyed especially in Greek summer settings. Aconitum (Monkshood): Misunderstood as poisonous to touch—false. Dangerous only if ingested. Blooms beautifully when few others do; it is resistant to deer and rabbits. Ellen wishes for a "Plant Mythbusters" show to debunk misinformation about plant toxicity. Daffodil (Narcissus): Linked to the myth of Narcissus falling in love with his reflection. Also central to the Persephone story, Zeus created a daffodil to lure her before Hades abducted her. Explains the origin of winter and spring cycles through Demeter's grief and renewal. Themes & Insights Plants in Greek mythology were deeply symbolic, medicinal, and magical. Many ancient uses align with modern scientific knowledge. The book groups plants thematically into short, easy-to-read chapters, ideal for bedtime or book clubs. Appeals to gardeners, historians, herbalists, and mythology enthusiasts. Ellen's Life & Work Today Now based in Santa Fe with a small, fully edible garden. Enjoys discovering new drought-tolerant plants in a vastly different climate. Former rooftop gardener in New York City; designed and maintained terrace gardens. Also teaches and speaks across the U.S.—including the upcoming Herb Society of America Conference in Texas (April). Other popular books: How to Forage for Wild Foods Without Dying, Backyard Foraging, The Wildcrafted Cocktail, The Forager's Pantry. Advocates for safe, informed foraging and appreciation of wild edibles. Mythic Plants features beautiful botanical illustrations by Lisel Ashlock. Mythic Plants makes a great gift and is available on Amazon! Find Ellen Zachos on Instagram.
