Just Grow Something | Evidence-Based Home Gardening

Fall is the best time of year to plant native perennials, and it's also the easiest. The seeds of most native wildflowers need a winter outside before they'll sprout, and plugs planted while the soil is still warm get a head start on roots before they go dormant. In this episode I'm walking you through why it's worth making room for natives at all, including what researchers are finding about the decline of butterflies, bumble bees, and the insects that birds depend on. Then we'll get into how fall and winter planting works, from dormant seeding after a few hard frosts to the six-week window for plugs, and how that changes if your winters are snowy, rainy, or barely there. After that we'll go plant by plant through milkweeds, coneflowers, black-eyed Susans, bergamot, asters, goldenrod, golden alexanders, and mountain mint, with whether each one is best started from seed, a plug, or either. We'll also talk about the plants that feed the lady beetles, lacewings, and tiny wasps that eat your garden pests. Let's dig in.

Every fall I look at my pepper plants loaded with fruit and my rosemary at its biggest, and I hate the idea of handing them over to the first hard freeze. The good news is you don't have to. Peppers, rosemary, and geraniums are all perennials somewhere in the world, and basil will keep going for a while on a windowsill if you start it right. But whether a plant makes it to spring gets decided mostly before it ever comes through the door. In this episode we're talking about which plants are worth the space, when to bring them in, and whether to keep them growing, put them to sleep, or just take cuttings. Then we'll get into my step-by-step for leaving aphids, spider mites, whiteflies, and fungus gnats outside, including why dish soap isn't the same as insecticidal soap and how long to keep new arrivals away from your houseplants. We'll finish with plant-by-plant care for peppers, rosemary, basil, and geraniums, plus a place where the experts don't agree. Let’s dig in.

Every fall somebody asks me if they can save the seeds from that amazing tomato or melon they just ate, and the answer is "maybe." Whether a saved seed grows into the plant you loved gets decided twice. The first time is months earlier, when the flower was pollinated, and the second is after harvest, when the seed either stays in the right conditions or doesn't. In this episode we're covering both. We'll talk about hybrids versus open-pollinated and heirloom varieties, which crops are easiest for beginners, why your zucchini and your pumpkin can cross but your cucumber and your cantaloupe can't, and why peppers cross more often than most people think. Then we'll get into harvesting and cleaning seeds, including what tomato seed fermentation does and doesn't do for seedborne disease, how to dry seeds without cooking them, the simple temperature-plus-humidity rule for storage, and why seed longevity charts don't agree with each other.

Canning gets most of the attention, but for a lot of what comes out of the garden, it isn't the best way to put food up. In this episode, we're opening up the rest of the preserving toolbox: freezing, drying, fermenting, refrigerator pickles, and good old-fashioned cold storage. We'll talk about why skipping the blanch (or cutting it short) costs you flavor and color in the freezer, which vegetables you can freeze raw, and why a full freezer rides out a power outage twice as long as a half-empty one. Then we'll get into drying in a humid climate, why vegetables need a blanch before the dehydrator, and what the research does and doesn't say about home freeze dryers. We'll make a simple, safe batch of sauerkraut, cover the one rule for fridge pickles, and wrap up with the temperature and humidity each storage crop wants, from potatoes and onions to carrots, sweet potatoes, and apples. There's a crop-by-crop quick-reference chart to download, and a fantastic fermenting book to check out. Let’s dig in!

A jar that seals is a jar that seals, and that's about all it tells you. In this episode, we're taking on four home canning myths that keep circulating in gardening groups, on food blogs, and in family recipe boxes: oven canning, open-kettle canning (and its cousin, flipping jars upside down), packing tomatoes and garlic in oil, and the idea that a salsa recipe can be tweaked however you like as long as it tastes right. For each one, we'll look at what the research from the National Center for Home Food Preservation and university extension services shows, why these methods fail, and what to do instead so your harvest stays on the pantry shelf and out of the danger zone. We'll also look at a study that checked 56 salsa canning recipes from food blogs, and what it found might make you rethink where your recipes come from. Let's dig in!
