Juliet Grape Tomato
Solanum lycopersicum 'Juliet'
vegetableJuliet is an indeterminate grape, or saladette, tomato that produces heavy clusters of shiny, elongated red fruit on vigorous vines. A 1999 All-America Selections winner, it ripens in about 60 days and keeps bearing until frost, and the meaty, crack-resistant fruit stores unusually well. Reliable and disease tolerant, it is a favorite for snacking, salads, and quick roasting.

🌱 Growing Guide
Start seed indoors 6 to 8 weeks before the last frost and transplant after the soil warms past 60F and nights stay above 55F, setting plants deep. Give full sun, fertile soil, and a sturdy cage or trellis for the long, productive vines, and water evenly. Grape tomatoes resist cracking better than most, but steady moisture and mulch still give the best fruit.

Good neighbors that attract beneficial insects or deter pests
- Basil — Deters whiteflies and thrips
- French Marigold — Reduces nematode pressure in the soil
- Calendula — Acts as an aphid trap crop
- Borage — Draws pollinators and beneficial wasps

🛡️ Pest & disease prevention
Proactive ways to stop trouble before it starts — tap a name with an arrow for its full guide
Plant dill nearby to attract parasitic wasps; inspect the undersides of leaves weekly
Interplant basil; use yellow sticky traps to monitor populations
Keep soil moisture even with consistent watering and mulch
🌾 Harvest & storage
Pick when deep red and firm. Juliet resists cracking and holds on the vine longer than round cherry types, so clusters can be harvested every few days without splitting.
🥗 Nutrition & benefits
Tomatoes are low in calories and a good source of vitamin C, potassium, and vitamin A, and they are the leading source of lycopene, the red antioxidant linked to heart and prostate health; firm grape types keep well and are eaten raw, skin and all.
⚠️ Toxicity & safety
Eat the ripe fruit only. Tomato leaves and stems (and large amounts of very unripe green fruit) contain solanine-type compounds and are not for eating.
