Why is your grapefruit plant turning brown from the tips toward the trunk and what can you do about it?

Your grapefruit plant may be turning brown from the tips toward the trunk due to factors such as underwatering, overwatering, or nutrient deficiencies. To address this issue, check the soil moisture to ensure it's not too dry or soggy, and adjust your watering schedule accordingly. Additionally, consider fertilizing with a balanced citrus fertilizer to replenish nutrients. Pruning the affected areas can also help promote new growth and improve overall plant health.
