Seeing yellow leaves on your urban planter box plants can be worrying. Don't panic—it's often a fixable issue. The most common cause is overwatering. Check the soil by sticking your finger an inch deep. If it's soggy, let it dry out completely before watering again. Ensure your boxes have drainage holes. Underwatering can also cause yellowing, especially with wilting, dry soil. Establish a consistent watering schedule. Nutrient deficiency is another culprit. Plants in containers exhaust nutrients quickly. Use a balanced, water-soluble fertilizer every few weeks during the growing season. Lack of sunlight may be the issue if plants are in deep shade. Most vegetables and flowers need at least 6 hours of direct sun. Relocate your boxes if possible. Finally, check for crowded roots. If plants are root-bound, gently repot them into a larger container with fresh potting mix. With these simple steps, your urban garden can return to vibrant green.
