My gardenias have yellow leaves. What to do, to stop the problem. |
It's normal for the oldest (innermost and lowest) leaves to turn yellow and fall off. The plant quickly replaces them with healthy new leaves. If the new growth is yellowing, it can indicate overwatering or a need for fertilizer. Gardenias prefer acidic soils. If you did not amend the planting area with peat moss, you can mulch over the soil surface with peat moss or compost and then feed your gardenia with an acidified fertilizer such as Miracid. You can feed every 4-6 weeks (or as recommended on the package). They like moist but not soggy wet soil. Wet soil may also cause yellowing. You might want to probe the soil between waterings to see how moist it is. If it is still moist a half inch beneath the soil surface, you won't need to water for another day or two. If it seems dry, go ahead and water. I hope this info helps. |
