| I planted an August Beauty Gardenia last spring. It did extremely well. Grew large and lush, perfectly green leaves. Now that winter is halfway through season, I have noticed brown on the leaves starting in stripes straight up the middle of the leaf. Then the browning moves outward throughout the entire leaf. Is this winter damage or more that I should worry about???? The whole plant seems to be affected by this..I covered the soil with straw in late fall. I haven't fertilized the gardenia with anything acidic..and it did great through Spring and Summer/Fall. I have Semi-clay soil with good drainage. |

| It looks as though your 'August Beauty' may have experienced cold damage. How low have your temperatures been this winter? Our 'August Beauty'gardenias have come through several thirteen degree nights without being injured here in SC. |

| I may be completely off base, but, when I saw Laccanvas's post in the Tennessee Forum, I was looking for some other explanation because of the specific pattern on the leaves. Most cold damage that I'm used to seeing doesn't manifest itself exactly like that. The plant is borderline for this area. Knoxville (where Laccanvas and I both live) is officially zone 6b and realistically somewhere around 7b, in recent years. Gardenia jasminoides is often listed as only marginally hardy in zone 7b (with a few exceptions). This year, early January brought several days in a row in the low teens. Foliar damage should be expected with temperatures like that. |

| We've been down in the low teens, but I have covered the base of the plant with straw....it seems like winter damage, but I maybe it is suffering from a deficiency???? I don't know..anyways thanks for the replies. |

| winter damage can be increased.. or caused solely by transplant shock.. until the plant is fully re-established ... your plant is less than one year in situ .. it is not established .... since we have no other facts about its size, planting or aftercare .... i can speculate no further... i wouldnt worry about it too much ... i have had small zone appropriate pines fully denuded after transplant after the first winter .. and they came back without a problem ... good luck ken |

| Awesome! Thanks! I am concerned for it..I love that plant. It seemed to do well throughout the summer..gaining height and color and width. Was my best plant with perfect foilage. That makes more sense that it is not fully established. Thanks again. |

| Gardenias can be hit or miss in upper zone 7. They really like some protection from wind. I've killed a lot of different (supposedly hardier) varieties. So far, my 'Frostproof' is doing OK. It gets some wind protection and part sun. |

| It hasn't been windy...just wet and cold then semi-warm then cold again. |

| That is cold damage. After tax day, April 15, put down some manure and nice pine mulch for it. Cut off the damaged part. If it is alive, it will spring back to life for you, just like it did last year. Don't wait til after April 15, or you won't get blooms this August. |
