How to plant
In this section we will learn how to plant False acacia (Robinia pseudoacacia), know its needs in terms of soil, watering and sun exposure.
Soil
False acacia (Robinia pseudoacacia) is a plant that adapts to all types of soils, chalk, clay, loam or sand.
-
The chalky soil is pale and contains chunks of calcium-rich rock. It is a fertile and well-draining soil, almost always alkaline.
-
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, Robinia pseudoacacia likes to grow in moist but well drained or well drained soils.
Sunlight
False acacia (Robinia pseudoacacia) should be grown in full sun places.
