How to plant
In this section we will learn how to plant Flowering rush (Butomus umbellatus), know its needs in terms of soil, watering and sun exposure.
Flowering rush (Butomus umbellatus) is not a demanding plant regarding the type of soil and can grow in clay, loam or sand.
Clay soil is composed of more than 25 percent clay particles. These particles have a high moisture holding capacity and the soil is heavy to dig and can be waterlogged in winter (dry in summer).
The loam soil is dark, rich in organic matter but balanced in minerals. It offers the best of all worlds, retaining enough water for the plants, but allowing excess moisture to drain away. This is the most desired type of garden soil, perfect for most plants.
Sandy soil is light, porous and very easy to drain. It is a soil poor in organic matter and nutrients. It is composed of relatively large mineral particles that allow water to drain quickly.
It is not very sensitive to soil acidity or alkalinity and grows well in soils with pH acid, alkaline or neutral.
Regarding drainage, Butomus umbellatus likes to grow in humid or poorly drained soil.
Flowering rush (Butomus umbellatus) should be grown in full sun places.
