If you are thinking about the flower garden outside the window, first you need to identify a few important aspects that should be considered before choosing varieties for growing outside the window:
- You need to think about the size of the mature flower and the depth of its roots, this will determine the size of the box you buy.
- Decide if you want to grow one type of flower in your boxes or create a variety. If you like different flowers, find out how plants behave towards each other.
- Think about growing conditions. Which side does your window face? How much sun or shade will the flower garden receive? The answers to these questions will help you decide what types of plants to plant. Once you determine your growing conditions, you will know if you should buy flowers that prefer full sun, partial sun, or full shade.
- You’ll want to create healthy growing conditions, of course, so use a quality potting mix and make sure the box outside the window has drainage holes so excess water can seep out when the tank is full.
