Due to their special construction, mound beds function in a similar way to raised beds, except that they are lower and do not require a special "box". For the first three to four years, mound beds are more suitable for heavy-feeding plants, although this includes both vegetable and ornamental plants. A common culture of crops and flowers is particularly pretty, which also offers many benefits for plant health.
Flowers also feel comfortable on the hill bed
The hill bed as a pure ornamental bed
While you have to be careful not to put any plants that store a lot of nitrate in the hill bed for useful plants in the first three years, this point is completely irrelevant for flowers and perennials - after all, you normally do not want to eat them. Only if you want to use herbs or medicinal plants (such as marigolds) accordingly should you consider this point and only plan the planting from the fourth year of use. Otherwise, all flowers feel comfortable on a hill bed, provided they like sun and warmth and have a high nutrient requirement. On the other hand, ornamental plants for meager and/or shady locations are not suitable for hill beds.
Mixed planting on the hill bed
A raised bed is wonderful for a mixed planting that not only looks attractive, but also has positive effects on plant health. Matching certain flowers and crops often offers significant benefits, especially when trying to keep pests and diseases at bay. For example, garlic is a real friend of roses because it keeps aphids away. However, some plant combinations also have a harmful effect on each other, so that a mixed culture should be carefully planned and coordinated. However, with such a mixed planting, always make sure that ornamental and vegetable plants do not deprive each other of nutrients, light and water. Ideally, you place the flowers on the outer areas of the hill bed, as a kind of border and in the apex, if they are higher species.
tips
Make sure to place the flowers according to their height on the mound: tall species such as sunflowers should be sown at the top, and lower species at the sides accordingly. The bushier a flower grows, the more it belongs at the edge, preferably at the northern end of the bed: this ensures that all other plants also get enough light.
