Tips for starting your window box flower project 

1. Map out the space 

It’s important to remember that window box flowers grow outwards and the window box they are growing in tends to get heavier over time as more soil and water is added. Ensure that your window ledges are sturdy enough and invest in a box bracket to keep the window boxes in place.

2. Think about the colours

What colours best match the personality and style of your home? Put time into thinking about this as your window box flowers will be the first thing you see when you get home from work. A little extra thought could go a long way. What colours best match your personality and the mood you would like to create? 

3. Match your maintenance to your availability 

When it comes to being a plant mom or dad, our downfall is often rooted in the fact that we take on too much too soon. If you don’t envisage yourself having a lot of time to care for your plants, go for the easy to mind variety that don’t require too much watering or pruning. Hardier varieties that can cope no matter what the climate work best for busy bees. 

4. Remember that variety is the spice of life 

Remember that variety is the spice of life! The more plants you include in your window box, the better it will look. Include vibrant flowers to command attention as well as “spiller” plants that will grow over the sides of the window box. Always double check the best soil varieties and weather conditions to match the flowers you are planting.
