> My orange jubilee gets yellow leaves. Is there a fertilizer I should use? Does it seem like too much water?
Yellow leaves usually indicate a nitrogen deficiency which is often a result of overwatering which can wash the nutrients away from the plant's roots. Water plants deeply to a depth of two feet every two weeks during the bloom season to promote more flower production, then after September, reduce watering to 3– 4 week intervals and don’t fertilize . You could fertilize lightly every 4-6 weeks just before and during the bloom season with a complete fertilizer like 19-5-9 but it is often not necessary. Or you could apply a slow-release fertilizer once, very lightly, at the beginning of the flower season.
