What Not to Plant with Geraniums

Introduction

Geraniums are a popular plant that can add color and fragrance to any garden. However, not all plants make good companions for geraniums. In this article, we will discuss some plants you should avoid planting with geraniums to help maximize their health and beauty.

Plant to Avoid #1: Tomatoes

Tomatoes are a frequent companion plant to many garden vegetables, but they should not be planted near geraniums. This is because tomatoes and geraniums have different soil requirements, and they also attract different pests. Tomatoes require a lot of nitrogen, which can cause geraniums to become stunted and less vibrant. Tomatoes are also susceptible to a fungal disease called verticillium wilt, which can spread to geraniums and other plants in the area.

Plant to Avoid #2: Brassicas

Brassicas, such as broccoli and cauliflower, should also not be planted near geraniums. These plants have similar soil requirements to tomatoes and also attract similar pests. In addition, brassicas are susceptible to a disease called clubroot, which can linger in the soil and infect geraniums and other plants. Clubroot infects the roots and causes them to become distorted, which can lead to stunted growth and eventual death.

Plant to Avoid #3: Nightshades

Nightshades, such as peppers and eggplants, are another group of plants that should not be planted near geraniums. Like tomatoes, nightshades require a lot of nitrogen and can deplete the soil of this nutrient. Additionally, nightshades can attract pests like aphids and spider mites, which can also harm geraniums. In some cases, the pests can even transmit diseases like tomato spotted wilt virus, which can affect geraniums and other plants.

Conclusion

In conclusion, planting the wrong companion plants with geraniums can lead to a host of problems, from stunted growth to disease. To ensure that your geraniums thrive, avoid planting them near tomatoes, brassicas, and nightshades. Instead, try partnering them with plants like marigolds, petunias, and snapdragons, which have similar soil requirements and can help ward off pests. By following these tips, you can enjoy healthy, vibrant geraniums throughout the growing season.
