Growing tomatoes in Zone 1 can be challenging due to the short growing season and cooler temperatures. Selecting the right companion plants can help improve growth, deter pests, and maximize your garden space. Here are the top five companion plants for Zone 1 tomatoes.
1. Basil
Basil is a classic tomato companion that enhances flavor and growth. It also helps repel pests like aphids, mosquitoes, and whiteflies. Plant basil near your tomato plants to enjoy these benefits and improve your garden’s aroma.
2. Carrots
Carrots and tomatoes make good neighbors because carrots help loosen the soil, making it easier for tomato roots to grow. Additionally, carrots can deter pests such as nematodes that might otherwise attack tomato roots.
3. Marigolds
Marigolds are known for their pest-repelling properties. They deter nematodes, aphids, and other insects that can harm tomato plants. Planting marigolds around your tomatoes creates a natural pest barrier and adds vibrant color to your garden.
4. Spinach
Spinach is a great shade provider for tomato plants, especially in warmer zones. It also grows quickly and can be harvested early, making efficient use of garden space. Spinach’s shallow roots do not compete with tomato roots, making them compatible companions.
5. Lettuce
Lettuce is another leafy green that pairs well with tomatoes. It grows fast and can be harvested multiple times, providing fresh greens throughout the growing season. Lettuce also helps keep the soil cool and moist around tomato plants.
Additional Tips for Growing Tomatoes in Zone 1
Start your tomato seeds indoors early to extend the growing season. Use row covers or cold frames to protect plants from frost. Choose hardy tomato varieties suited for cooler climates to ensure a successful harvest. Companion planting, proper soil preparation, and season extension techniques can make a big difference in Zone 1 gardening.
