|I have a sequoia tree in a pot that is over 5 feet tall. Lately the ends of the branches are turning brown. I feed it 1x a month with a container fertalizer.

|Plants in containers can be overly sensitive to hot temperatures because their roots are confined and the potting soil and container can get too hot. This can cause burning and subsequent browning foliage. Over or under watering or a build up of fertilizer salts can cause the same symptoms. Feeding once a month might be excessive unless you dilute the fertilizer to half strength and plan on flooding the soil every month or so to leach out any excessive salts. Sequoia's can grow into very large trees which means their root systems can be quite extensive. You might consider moving your sequoia to a larger container and using fresh potting soil. This should help. Always water thoroughly and allow the top of the soil to dry out between waterings. Hope this information helps!
