I'm new to my house, and I have a half dozen containers just underneath a giant sequoia. I now see a small amount of the needles are falling into the containers. Will the sequoia needles harm the plants in the containers? Should I remove the needles or move the containers?

I can see nothing grows directly under the tree where there are lots of needles. And I've always heard cedar(-like) trees did something to the soil to prevent plants from growing. I've also read that while needles are acidic, they break down in compost pretty quickly, but here they're falling directly into the containers not being composted. Any advice would be helpful!

  • what's growing in the containers? Annuals, perennials, vegetables???

In permanently potted plants, you can remove the buildup if it becomes too great. It shouldn’t pose any threat in small amounts, or over the course of a single season.
