FAQS

How do I plant low maintenance plants in window boxes?

From drought tolerant plants to shrub that love a whole lot of sun, there are many low maintenance plants to choose from but if you're wondering what would be the best way to plant them in window boxes — then we've got you covered.

Laura tell us: 'Make sure to read your labels. Make sure you use plants that will stay small enough and not outgrow or crowd out other plants. Use moisture-control soil, which contains water-retaining pellets that release moisture as needed, can help maintain the ideal moisture level, ensuring healthier plants and less frequent watering'.

She says you also need to ensure your window boxes have adequate drainage to keep soil from becoming waterlogged which could lead to root rot, especially when using plants that prefer drier conditions. Laura adds: Depending on the size of the window box, we like to incorporate anywhere from three to eight plants of any one variety. We tend to place our taller, more dramatic thriller plants in a zigzag or wave pattern toward the cente'.

As for spiller plants that cascade down, Laura says you can tuck these into corners and dot them along the edges. 'Make sure to walk away from your container often so you can take a view from afar and make sure you are spacing your plants correctly. It is easy to get carried away and find you've run out of plants due to having them spaced too closely!' Laura adds.

How do I care for low maintenance window box plants?

Remember, 'low maintenance doesn't mean no maintenance,' Laura emphasizes. 'Window boxes by nature dry out quickly because they are often shallow and are placed under eaves where they don’t receive rainfall'.

Be sure to regularly water your plants 'especially if your boxes are in full sunlight or you’re experiencing a heatwave' and last but not least, Laura says 'aim to keep the soil evenly moist and your blooms will reward you all season long!'
