Certified ExpertA.Your grapefruit tree will benefit from a slightly nitrogen rich or balanced NPK fertilizer (such as 8-8-8). Additional information on citrus tree fertilizer can be found here:

Charleston, SCQ.Grapefruit tree
I read your article on why my grapefruit tree won't bear fruit. I have a 15 year old grapefruit tree that is about 30 feet tall. It started bearing beautiful grapefruits after about 5 years but 2 winters ago we had a very bad winter and the tree lost all its leaves and didn't produce fruit the following season, then the next winter the same thing - a very cold icy winter and lost all its leaves again. Right now the tree has very healthy looking leaves but I don't see any signs of grapefruits again. When do you think I will get fruit again? I did have to cut the tree back some because it was planted too close to my house and it was growing into my bedroom window. Any advice would be appreciated because I miss my grapefruits.

August 5, 2015Q.grapefruit tree needs root ball trimmed
Someone told me several years ago I should use kitchen shears to cut off a couple of inches all around and under the root ball. It's in a huge pot now. Can't put in bigger pot. I couldn't move it all if I put it in a bigger pot. I love it. I grew it from a seed and it got 2 stories high. I lost my house and had to cut it down as much as I could to get it into the apt. I qualified for. It's about 8 feet tall now. I know it needs to be taken care of soon.

August 9, 2015Q.grapefruit skin turning brown
My grapefruit tree appears healthy. The fruits are growing well. The skin looks rusty, especially on the underside. The leaves are nice and green. Is this a problem? The brown areas are flat and does not interrupt the rind.

Pacific coastQ.Grapefruit tree
I have a grapefruit tree in my backyard in Los Angeles that I planted about 12 years ago. It started giving fruits a couple of years ago, but the fruit is smaller than a small orange, very bitter and the skin turns yellow in August. Is there a chance for this tree to produce normal grapefruits or I should cut it?

August 21, 2015A.I wouldn't throw in the towel yet.
I would first recommend a soil test. This can really help determine what may be missing in the nutrients or what corrections can be made in amending the soil. Since you said you have had poor fruit since planting this could very well be the issue.
Water and proper amounts on Nitrogen and Phosphorous are very important.
Environmental issues can be responsible for many citrus fruit issues.
I have listed a few links for you to refresh you on the care requirements.https://www.gardeningknowhow.com/edible/fruits/grapefruit/growing-grapefruit.htm

August 22, 2015A.Yellowing leaves can indicate a watering issue, to much or to little.
Add water if you feel it's dry. Mulching with 2 to 3 inches of hardwood mulch.Here are some links for you with more information.

September 5, 2015Q.when to remove fruit
When grapefruit is not ripe, must we remove it when the new blossoms come in?
- Answered by

September 8, 2015A.I would not pick them before they are ready. Most citrus fruits, especially grapefruit, do not ripen once they are picked. In fact, grapefruits are best left on the tree awhile, as they will become sweeter. Grapefruit harvesting normally takes place in fall. When the fruits are yellow or golden in color, then they are ready for harvesting.
