My Thomasville citrangequat has had yellow leaves on the lower branches since late fall. The yellowing seems to be advancing upward. I planted the small seedling last spring and it's now 3 ft tall. When I planted it , it had yellowed leaves and it greened up after treatment with miracle grow water soluble acid fertilizer. I saw a post about a yellowed grapefruit and everybody told her to give it magnesium and micronutrients . Should I wait until spring to give any kind of fertilizer? |

Depending on local conditions, Citrangequat and other Poncirus hybrids can have a tendency to yellowing leaves and even leaf loss during the winter. This trait results from the fact that the parent trifoliate orange is normally deciduous. |

My coldest night last year was one night of 14 degrees, this winter so far my coldest temp was 19 degrees. I've only had about 10 nights at or below freezing here this "winter". I'm usually 10 degrees warmer up here than than in the surrounding valleys over night, and 5 degrees cooler during the day... |

I was wondering about this. My citrangequat is doing the same thing (Metro Atlanta). I've tried citrus fertilizer, magnesium, with not much effect. I was hoping it was just a deciduous trait. |

Citrus leaves have a normal life span of about 2 years + or -. In the early spring of the year when a citrus tree begins to produce a flush of new leaf growth, it is also the time when a lot of the old leaves are ending their two year life span, and begin to fall from the tree. Before the old leaf actually falls from the branch, the tree pulls out most the nitrogen remaining in the old leaf to be reused once again by the tree, which causes the dropped leaves to have a yellow appearance. Nothing is wasted. Leaf abscission at this time of year is a very common part of a citrus tree's life. - Millet |
