What Is The Best Depth For A Planter Box?

Planter boxes allow you to grow plants in even small spaces such as the balcony or patio. But plants need adequate soil and space for proper root growth and development and if the planter box is not deep enough, it can restrict the plant’s ability to thrive. So if you’re wondering what is the best depth for a planter box, we’ve got a few tips and tricks to help you determine which planter box designs will work for you!

For most plants, a 6 to 8 inch deep planter box is sufficient enough to develop healthy roots. However, the depth may vary according to the type of plant and its size. If you’re planning to grow a kitchen garden with fresh herbs and microgreens, a shallow planter box such as our rectangle moss planter boxes with inner lining will also work perfectly.

Similarly, flowering plants often have a shallow root system and can grow well in plastic planter boxes that are about 8 inches deep. We suggest that you opt for our large decorative planter pots to allow your floral plants to reach their full potential and optimal health.

However, if you’re looking for decorative planter boxes to hold artificial plants and flowers, the depth of the box doesn’t really matter as you can adjust the stems of your faux floral and foliage arrangement according to your planter box. Our vertical raised planter box stand and natural wooden planter boxes are the ideal choices to stylishly arrange a gorgeous assortment of artificial flowers, faux succulents, and fake foliage elevating your decor up a notch.  

Thus, we can say that the best depth for a planter box is 6 to 8 inches as it gives the plants enough room to spread out their roots. We offer an unmatched collection of planter boxes, pots, and stands at unbelievably low prices to help you achieve your indoor garden dreams.
