Problems with my Gold Mop Cypress
Thanks for writing. Browning of the foliage could be represented by too much or too little water, too much fertilizer, too much direct sun (some varieies of golden false cypress need some protection fom the hottest afternoon hours, especially in your area), or a number of other conditions. Check the soil moisture by sticking your finger in the ground near the base of the plant; if it's moist, you probably don't need to water.
