A deck is a great gathering space for family and friends when the weather is nice, but it can become overcrowded quickly. Most decks quickly become cluttered with tables and chairs, a grill, kids' toys and more; so bringing in plants, herbs or flowers often feels out of the question.

However, if you're looking to add some pops of color, grow herbs or simply create some colorful ambience, you might benefit from a deck rail planter. A deck rail planter is a great way to add lush vegetation to your deck without taking up valuable space. These planters are made to go directly on top of or on the side of your deck railings to keep them secure and off the ground.

There are a few types available, too. There's the saddle planter, which is an over-the-rail planter that you put directly on the top of the railing. These sit snug on top, but you'll need to measure the width of your railing to ensure it fits properly. There are also ones that clamp on with brackets, which allow the plant boxes to hang over the railing rather than on top and are more of a universal fit.

Whichever style may be best for you, a deck rail planter will add some botanical beauty to your deck and allow you to have a nice herb or vegetable garden accessible to your kitchen without clutter. It's a great way to style a deck this summer, and we've rounded up our favorites you can buy online below.
