10 flowers you should NEVER plant near marigolds
While marigolds are versatile and beneficial in many garden settings, there are specific flowers that should not be planted nearby. These include roses, petunias, geraniums, sunflowers, daisies, lilies, tulips, pansies, chrysanthemums, and zinnias. Each of these flowers has unique characteristics that can negatively impact marigolds when planted too close.
5. 1. Roses: Competing for Nutrients
Roses are heavy feeders, requiring a lot of nutrients to thrive. When planted near marigolds, they can compete for essential nutrients like nitrogen, phosphorus, and potassium. This competition can lead to reduced growth and flowering for both plants.
Additionally, roses prefer a slightly different soil pH, around 6.0 to 6.8, which can create conflicts if the soil conditions are not carefully managed.
6. 2. Petunias: Attracting Pests
Petunias are known to attract certain pests, such as aphids and caterpillars, which can also affect marigolds. Planting them together can increase the likelihood of pest infestations, leading to damage and reduced health for both plants.
While petunias and marigolds can both thrive in sunny conditions, the increased pest pressure can outweigh any potential benefits of planting them together.
7. 3. Geraniums: Clashing Growth Habits
Geraniums have a sprawling growth habit that can overshadow marigolds, especially if they are planted too closely. This can lead to reduced sunlight exposure for marigolds, which need full sun to thrive.
Additionally, geraniums can compete with marigolds for water, as they also require consistent moisture to maintain their lush foliage and blooms.
8. 4. Sunflowers: Overshadowing Marigolds
Sunflowers can grow quite tall, often reaching heights of 6 feet or more. When planted near marigolds, they can easily overshadow them, blocking the sunlight that marigolds need to flourish.
Furthermore, sunflowers have extensive root systems that can compete with marigolds for water and nutrients, further hindering their growth.
9. 5. Daisies: Competing for Space
