Crop notes
Tomato: Pinch suckers on indeterminate types. Cage or stake before they sprawl.
Pepper: Slower than tomatoes — start a week earlier. Wait for soil to hit 65°F before transplanting.
Eggplant: Heat lover — black plastic mulch helps in our short Utah summers.
Cucumber: Cucurbits hate root disturbance — use 4" pots or soil blocks if starting indoors.
Zucchini: One zucchini plant feeds a family. Two will overwhelm a town.
Summer Squash: Yellow crookneck and patty pan in this category. Pick small for best flavor.
Winter Squash: Cure for two weeks at 80°F to sweeten and harden the rind for winter storage.
Melon: Stop watering a week before harvest to concentrate the sugars.
Sweet Corn: Plant in blocks of at least 4 rows for proper pollination, not single long rows.
Beans (Bush): Inoculate seed with rhizobia the first time you plant a bed — fixes its own nitrogen after that.
Pole Beans: Trellis 6 ft tall. Pick every other day at peak — they hide on the vine.
Lettuce: Bolts when night temps stay above 70°F — succession every 2 weeks until late June, then resume in late August.
Spinach: Fall is the better crop in Utah — sow Aug 15 for harvest into November under a cold frame.
Kale: Sweetens after the first frost. Lacinato (dinosaur) holds quality longest into winter.
Broccoli: Heads bolt in heat — best as a fall crop here. Start seed mid-June, transplant late July.
Cabbage: Heads split if you let them sit too long once mature — twist 90° to slow water uptake.
Cauliflower: Tie outer leaves over the head once it forms to keep heads white (blanching).
Brussels Sprouts: Long-season crop — start mid-March for fall harvest. Snap off lower leaves as sprouts swell.
Collards: More heat-tolerant than kale. Pick lower leaves and the plant keeps producing all season.
Bok Choi: Bolts in heat — strict spring + fall crop here. Baby bok choi at 30 days is the sweet spot.
Arugula: Peppery flavor sharpens in heat — pick young leaves before flowering for milder taste.
Swiss Chard: Most heat-tolerant of the leafy greens — produces all summer in Utah where lettuce bolts.
Carrot: Don't let the bed dry out before germination — light burlap cover keeps moisture in for the 14-day wait.
Radish: Fastest crop in the garden — kid-proof and confidence-building. Succession every week.
Beet: Each "seed" is actually a cluster — thin to one seedling per spot or you get tangled roots.
Turnip: Greens are arguably better than the root — pick young leaves for salads while roots size up.
Pea: Trellis from day one — they will find it. Pinch the tops to thicken the vines.
Onion: Long-day varieties only at our latitude (Walla Walla, Patterson, Yellow Sweet Spanish).
Leek: Hill soil up around the stems as they grow to blanch the white shanks. Hardy through November.
Garlic: Plant cloves in October, harvest the following July. Hardneck varieties (Music, German Red) for Utah winters.
Basil: Pinch flower spikes the moment you see them — flowering = bitter leaves and shorter life.
Cilantro: Bolts fast in heat — succession every 2 weeks. Let some bolt for coriander seed.
Parsley: Slow germinator — soak seeds 24 hours before sowing. Italian flat-leaf has more flavor than curly.
Dill: Lets itself go to seed and self-sows — designate a "dill corner" and forget about it.
Oregano: Perennial — comes back every year. Greek oregano (O. vulgare hirtum) has the strongest flavor.
Thyme: Perennial. Cut back hard after flowering to keep plants tight and productive for years.
Sage: Perennial. Tricolor and purple sage are decorative AND edible — earn double duty in the herb bed.
Rosemary: Borderline hardy in Utah — bring potted plants inside before hard freeze, or treat as annual.
Mint: Plant in a sunken pot or it WILL take over the bed. Spearmint, peppermint, mojito, and chocolate mint all behave the same way.
Chives: Perennial. Purple flowers are edible and gorgeous in salads. Cut back to 2" mid-summer for tender regrowth.
Tarragon: French tarragon doesn't come true from seed — propagate from cuttings or buy plants. Russian tarragon from seed has weaker flavor.
Strawberry: Everbearing varieties (Quinault, Eversweet) crop spring AND fall. Pinch flowers the first year for stronger crowns.
Raspberry: Heritage (everbearing) gives you a fall crop the same year. Trellis between two T-posts and prune dead canes in winter.
Watermelon: Sugar Baby is the right size for short Utah summers. Tap test: ripe melons sound hollow.
Cantaloupe: Slip-test: ripe cantaloupes detach from the vine with light pressure on the stem.
Zinnia: Cut and come again — the more you cut, the more it blooms. Benary's Giants are the cut-flower workhorse.
Marigold: Repels root-knot nematodes — interplant with tomatoes. Deadhead for continuous bloom.
Sunflower: Mammoth varieties hit 12 ft. ProCut series gives single-stem cut flowers in 60 days.
Cosmos: Self-sows aggressively. Don't fertilize — rich soil makes huge plants with few flowers.
Nasturtium: Edible flowers and leaves — peppery like watercress. Trap crop for aphids — keeps them off vegetables.
Sweet Alyssum: Honey-scented carpet of tiny flowers. Beneficial-insect magnet — interplant with veg beds for pollinator support.
Calendula: Petals are edible — color salads and butter. Resilient through light frost on both ends of the season.
Snapdragon: Cool-season cut flower. Pinch above 3rd leaf set for branching plants. Rocket and Madame Butterfly series for cuts.
Cosmos (Sensation): Tall variety — 4 to 5 ft. Stake or grow against a fence. White, pink, magenta single blooms on airy foliage.
Cherry Tomato: Sweet 100, Sungold, Sweet Million — pick a yellow + a red so kids ask for both. Indeterminate — they don't stop.
Roma Tomato: Determinate paste tomato. Fruits ripen together — best for canning, salsa, sauce. Less juice, more flesh.
Beefsteak Tomato: Big sandwich slicers — Brandywine, Mortgage Lifter, Cherokee Purple. Long-season; Utah barely fits the window.
Grape Tomato: Smaller and more elongated than cherry. Juliet and Five Star are reliable producers, crack-resistant.
Early Girl Tomato: First ripe tomato of the year — earlier than anything else for slicing. Indeterminate but compact.
Yellow Pear Tomato: Mild flavor, ornamental shape. Indeterminate — keep producing until frost. Great for salads and kids.
Rapunzel Tomato: 40+ cherry tomatoes per truss in a long pendant. Showstopper at farmers markets. Indeterminate, vigorous.
Sun Sugar Tomato: Honey-sweet golden cherry. Crack-resistant where Sungold splits. Our staff favorite — they don't make it inside.
Jet Star Tomato: Classic mid-size red slicer. Disease-resistant, low-acid, reliable. Indeterminate, heavy producer.
Big Boy Tomato: The classic 1-pound red slicer. Stake heavily. Use one slice per sandwich.
Red Bell Pepper: Sweet, no-heat. Most varieties start green — leave on the plant 2-3 more weeks for full red color and triple sugar.
California Wonder Pepper: Heirloom 4-lobe blocky bell. Thicker walls than many newer cultivars. Best harvested green or red.
Sweet Canyon Pepper: Long Italian-style sweet pepper. Prolific producer. Excellent fried, stuffed, or sliced raw.
Cayenne Pepper: 30,000–50,000 SHU. Dry whole pods or grind for cayenne powder. Pick when fully red for best heat.
Serrano Pepper: 10,000–25,000 SHU. The salsa pepper. Use green for fresh salsas, let ripen red for hot sauce.
Rainbow Bell Mix: Mix of red, yellow, orange, and purple bells. Plant 4-6 in a row for a colorful market harvest.
Gigantia Pepper: Extra-large bell. Each fruit can hit half a pound. Stake plants — they tip with the weight of fruit.
King of the North Pepper: Bred for cool climates — sets fruit at lower temps than most bells. Reliable producer at our elevation.
Iceberg Lettuce: Crisphead — needs 60-day cool window. Spring crop only at our elevation; bolts in July heat.
Asian Baby Lettuce Mix: Mizuna, tatsoi, mibuna, baby bok choi. Cut at 4" tall for spicy salad mix. Regrows 2-3 times.
Red Onion: Red Wing and Cabernet are reliable long-day reds for Utah. Sweet enough for raw use, store 4-6 months.
Bunching Onion (Scallion): Evergreen and Tokyo Long White produce all season. Cut tops to 2"; they regrow.
Sweet Basil: Genovese-style. The pesto basil. Fast bolting in heat — pinch flowers aggressively.
Italian Basil: Larger leaves than sweet, similar flavor profile. Good for layering whole leaves on caprese.
Spearmint: Classic mint for tea, mojitos, lamb. Aggressive runner — keep in a sunken pot.
Peppermint: More menthol than spearmint. The hot-cocoa, peppermint-tea mint. Same containment rules.
Chocolate Mint: Hint of cocoa scent. Pairs with vanilla ice cream and dessert garnishes. Same containment rules.
Mojito Mint: The Cuban mint for actual mojitos — smoother and less menthol than peppermint. Same containment rules.
Tricolor Sage: Variegated cream/green/purple foliage. Decorative AND edible. Perennial, drought tolerant.
Purple Sage: Deep purple foliage all season. Same culinary use as common sage but striking in mixed planters.
Garlic Chives: Flat-leaf chives with a mild garlic flavor. White flowers in late summer — edible. Perennial.
Geranium: The hanging-basket workhorse. Pelargonium, technically. Deadhead for continuous bloom all summer.
Petchoa Supercal: Petunia × calibrachoa hybrid. More vigor than calibrachoa, larger flowers than petunia. Mother's Day basket favorite.
Pansy: Cold-tolerant — flowers through 28°F. Perfect for early spring planters and fall mums replacements.
Horned Violet (Viola): Smaller flowers than pansy but more of them. Trails nicely from edges of containers.
English Daisy: Tasso Mix — pompom blooms in pink, red, white. Cold-hardy biennial; treat as cool-season annual here.
Forget-Me-Not: True blue is rare in flowers — Bluesylva delivers it. Self-sows; you'll have it forever once established.
Wallflower (Bowles Mauve): Tender perennial — blooms spring to fall in mild winters. Sweet fragrance. Cottage-garden classic.
Hellebore (Lenten Rose): Blooms when nothing else does — Feb through April. Evergreen. Deer ignore them. Slow to establish, lives 30+ years.
Thrift (Splendens): Cushion of grass-like foliage with pink pom-pom flowers. Drought-tolerant rock-garden perennial.
Stonecrop (Lime Zinger): Succulent perennial — chartreuse leaves edged red. Drought-tolerant, deer-resistant. Pink flowers in fall.
Anemone (Harmony): Plant corms in fall for spring bloom. Long-lasting cut flower. Soak corms 4 hours before planting.
African Daisy (Harvest Moon): Osteospermum — closes at night and on cloudy days. Heat- and drought-tolerant once established.
