Tomatoes and Corn: A Bad Neighbourhood

Tomatoes and corn might sound like a classic combo for a summer garden, but in reality, it’s a bad neighborhood for your tomatoes. Both these crops are heavy feeders, competing for the same nutrients in the soil. It’s like sharing a pizza with someone who loves the same toppings as you – it leads to a battle for the last slice.

Garlic and Tomatoes: A Smelly Relationship

Garlic is known for its pungent aroma, but that’s not the only reason it shouldn’t be planted near your tomatoes. These two don’t just clash in scent, but they can also inhibit each other’s growth. Tomatoes can stunt garlic’s development, while garlic can deter pests that often trouble tomatoes. It’s a love-hate relationship in the garden.

The Leafy Greens Dilemma

Leafy greens like lettuce and spinach, while nutritious, aren’t the best buddies for your tomato plants. They compete for sunlight and space, which can lead to overcrowding and hinder proper air circulation. This can result in disease and pest issues, creating more work for you.

Tomatoes and Potatoes: A Nightshade Family Feud

Tomatoes and potatoes belong to the same plant family, the Nightshades. While family gatherings can be enjoyable, this one’s a feud. Planting them together can increase the risk of transmitting diseases like early blight or late blight. Keep these nightshades apart for a healthier garden.

The Herbs That Can Help

Not all herbs are troublemakers in the garden. Some, like basil and parsley, make excellent companions for tomatoes. They help deter pests and enhance the flavor of your tomatoes when used in cooking. It’s like having your favorite condiments ready for your pizza.

Marigolds: Your Tomato’s Best Friend

Marigolds are like the best friend your tomatoes never knew they needed. These vibrant flowers not only add color to your garden but also act as natural pest repellents. They keep away nematodes and other harmful insects that can harm your tomatoes. Consider planting marigolds alongside your tomatoes for a healthier, pest-free garden.
