Yes, they need drainage holes to allow excess water to escape.  Proper drainage is important for the health of the plants in the window  box because it helps prevent water from collecting at the bottom of the  container, which can lead to root rot and other problems.

Without drainage holes, water can become trapped in the bottom of the  window box, which can suffocate the roots of the plants and cause them  to die.

Drainage holes allow the excess water to drain out of the bottom of the container, which helps prevent this from happening.

If your window box does not have them, you can drill some holes in the bottom of the container yourself.

It’s important to make sure that  the holes are large enough to allow water to escape but not so large  that soil will fall out of the bottom of the container.

Make a few drainage holes to help water get out and if you are concerned  about soil washing out, use a piece of weed fabric in the bottom to  help keep it in.
