It's not recommended to put grass seed over beans that have been planted for a week. Here's why:
* Competition for resources: Beans and grass will compete for the same resources like water, sunlight, and nutrients. This competition can hinder the growth of both plants.
* Shading: Grass can quickly grow and create a dense canopy that will shade your beans, depriving them of the sunlight they need.
* Soil disturbance: Planting grass seed over existing beans will likely disturb the soil and potentially damage the bean roots.
Alternatives:
* Separate planting: Plant your beans and grass seed in separate areas to avoid competition.
* Staggered planting: Plant beans first, and then wait until they are established before planting grass seed in a different section of the garden.
* Companion planting: Some companion plants for beans (like marigolds) can help deter pests and improve soil health without competing for resources.
If you are determined to plant grass seed over your beans, ensure it's a thin layer and water sparingly to prevent the beans from being suffocated. However, it's best to choose a different approach to avoid potential problems.
