How to plant a window box?
Before you proceed to planting flowers into your window boxes, there are some factors you should consider beforehand. First, you need to measure the length of your windows and decide what design you are going for. You can either make your planter yourself or buy a new one.
Whatever your choice is, your window box should be well-secured and installed on the wall outside. In fact, there aren’t too many steps one should follow to install window boxes properly. But if you think you don’t want to mess up with that, feel free to hire professional landscapers who will do this for you.
Apart from asking yourself how to plant a window box, perhaps you are also wondering how deep a window box should be or what to put in the bottom of a planter for proper drainage. Well, first of all, pick a container that has drainage holes and then add a layer of broken terracotta pots to prevent water lodging.
After that, add a layer of compost to feed the soil as well as gravel to allow the water to drain easily. You can add another layer of compost to your container, too. All that is left to do now is to plant the flowers of your choice.
Carefully take your plants and flowers out of their pots and place them into your window box container along with their soil. Make sure you don’t hurt their roots while doing so. Remember not to put your window box flowers too close together as this will create an ideal atmosphere for plant diseases to spread.
As soon as you are done planting, apply some more compost between the plants to fill the gaps. Press the compost down using your fingers and water your plants. Some people prefer to do so before planting, but you can water them after you add them to your window box. This is how easy it is to plant a window box. If you haven’t decided what plants you want to grow, we hope that our suggestions below will serve you well.

How to combine plants?
Combining various plants in the same pot can result in a great-looking window box project. However, the growing conditions of all the plants you want to grow together should be taken into consideration. Some plants need frequent watering, others prefer less water.
Overwatering or underwatering plants may actually lead to killing them. Sunlight exposure is also another major factor to consider. Therefore, in order to grow healthy plants, they should all be given the care they demand.
Your container gardening companion plants should have the same preferences in order to thrive successfully in window boxes. As mentioned above, try not to mix sun-loving varieties with shade-loving window box flowers. The best way to decide what plants and crops you can grow in window boxes is to check the direction your window is facing.
If it gets plenty of sunlight daily, then sun-loving plants will do just fine for you. Yet, you can go for plants for window boxes in shade if your window doesn’t get enough bright light during the day.
Tips for a perfect window box
- Choose the right potting soil – If you want your window box flowers to grow happily and thrive, then plant them in a good quality potting soil. This way you won’t have to replace it every year.
- Don’t forget to fertilise your plants – This way you will provide them with the necessary nutrients they need to grow well. First, we’d recommend that you start with a slow-release fertiliser. After that, you can start applying liquid fertiliser regularly to ensure your plants get the minerals and nutrients they need.
- Water your window boxes often – Soil tends to dry out quite fast so try to keep it moist by watering your plants frequently. This is an absolute must-do task to make sure your window boxes get really impressive. Otherwise, the plants will dry out and die.
- Provide proper drainage in your window boxes – “What to put in the bottom of a window box?”, you may ask. Well, a few pieces of old broken terracotta will work just fine. They will help improve the drainage of the soil in your window boxes but make sure the containers have drainage holes.
Window boxes bring walls back to life with their vibrant-coloured flowers. They can easily increase your property’s curb appeal and make a great addition to your overall landscape. No matter what type of plants you choose to go for, give them time to thrive and take care of them regularly.
