Q.Sago Palm Brown Leaves
My sago palm leaves begin to turn brown shortly after growth, this only occurs during warmer/summer months whereas winter the leaves stay green all season. I’ve tried trimming the infected leaves each year but they keep regrowning and turning brown over and over every end of spring/summer.

There are a lot of plants under the sago which may be taking water and nutrients from the sago palm or holding water close to the sago. Also, if you are constantly watering the plants under the sago, it may be getting too much water. Sagos need well drained soil and will succumb to root rot if they get too much water. Nutrient deficiencies can also contribute to yellow/brown leaves.
