Your sandy soil garden might be difficult at times, but do not despair! Using these “best plants for sandy soil” perennial lists, you can create a beautiful extended-bloom garden. The key to success in your sandy soil garden is to understand the properties of this soil type and to choose plants that have adapted to thrive there.
That way, instead of fighting with nature for plants that don’t want to live there, you can sit back and enjoy a great looking garden with very little maintenance.
How to ID and Understand Your Soil Type
Soil plays a critical role in determining what plants will grow happily and thrive, or what plants will struggle and die. Learning what type of soil you have in your garden is important to help choose what will succeed there. In general, soil is made up of a percent of each clay, sand, and silt. Clay is the smallest soil particle while sand is the largest, with silt finding the happy medium in between.
Most soils lean towards one of these components, but still encompass smaller percentages of the others. There are strengths and weaknesses of all types of soil. Some drain better, while others hold onto water tighter. Some hold nutrients while others are more sterile. Some erode quickly and some have little aeration.
Understanding what type of soil you have and its strengths and weaknesses will help you determine what plants will live happily in your garden.
So what does it mean if you’ve determined that your soil is dominated by sand? Because sand is the largest soil particle it means that water can move through the large pore spaces rapidly. This fast drainage is an advantage for growing plants that like to be dry.
However, sandy soils are typically low in nutrients. This is because the large pore space and fast drainage washes out any available nutrients.
Sandy soils also warm up and cool down relatively quickly from the air temperature changes, meaning growth in the spring will start quickly but cool nights in the autumn will make the perennials go into dormancy earlier as well.
In general, perennials that prefer sandy soils are happy being on the drier side and function well with little nutrients – a great recipe for a lower maintenance garden!
Here is a list of some of the most reliable perennials for your sandy soil garden. Whether you are looking for a specific color, height, or bloom time in your region, this list will help you identify what would be perfect for what you need!
