Answer: Browning leaves can indicate over watering or even fertilizer burn. Plants in containers should be watered thoroughly and then the top inch of soil should be allowed to dry out before you water again. To check soil moisture, water completely then wait 3-4 days and dig down into the soil. If it is still moist one inch below the surface, you won't need to water for a few more days. If the soil is dry, it's time to water. When you feed, use a half strength dilution of liquid fertilizer, once a month during the growing season. I use half strength Miracle Gro for my potted trees. Diluting the fertilizer ensures you won't burn the roots with a heavy concentrate, but the roots will still get the nutrients they require. Hope this information is helpful. Best wishes with your trees.
