Q. Amount (Gallons) of Water for Citrus Trees

I want to install a drip water system for my three citrus trees: 1 grapefruit and 2 orange. In far southern Texas, how many gallons of water do I need weekly per tree? I will be gone, so it needs to be set. How about Hibiscus bushes?

Q. Grapefruit Leaf Drop

I live in Stuart, FL. and have a small grapefruit tree, which was infested with Sri Lanka weevils. I sprayed the tree with dish soap and water, the same as I did when my gardenias had aphids. A few days later the tree had severe leaf drop and fruit drop. Will the leaves grow back, and did the soap make the leaves fall off, or could it have been the hot, dry weather or the weevils or what? I would like to avoid this ever happening again.

Q. Leaves Rolling at Tips

My potted grapefruit tree has leaves at the top that are rolling at the tips. The bottom leaves are nice and flat. What is wrong, and how do I fix this problem?

If the leaves turn black and curl up, the plant is probably being kept too cold. It prefers warm, tropical-like temps. If the leaves stay green but curl up, that is a sign of too little light. Try and keep the plant in full sun at least 4-6 hours a day for best results. This article will help: https://www.gardeningknowhow.com/edible/fruits/grapefruit/growing-grapefruit.htm

Q. Many Yellow Curled Leaves

I have a potted grapefruit tree. The cause may have been putting it out too early (a slight freeze) or my stupid watering/not watering regimine, but it has lost about 20% of its leaves. About 3/4 of the remaining leaves are sort of a lighter green and curled. It is potted in Miracle Grow citrus potting soil. The soil is pretty moist right now. What to do?

It might need fertilizer. Even planted in fertilize potting soil, they need fertilizer regularly to replenish what gets washed out when watering and just what they use. This article will help:

Q. grafting to a root sucker

I started a grapefruit tree from a seed of a hybrid. I want the tree to bear fruit. I saw a root sucker forming on the trunk close to the soil line. Can I graft to the root sucker? It is in its infancy stage, but maybe it will grow larger and could it be used to graft to. Or should I graft to a branch?

Grafting to a sucker may work. I would separate it though and allow it to develop its own solid root system first, otherwise, it would never quite get enough from the mother plant to really do well. If this is not what you want, I would graft to the branch then.

Q. Rooting a Grapefruit

I was eating a grapefruit and 3 of the seeds in it had roots on it, so I planted them in pots and they sprouted nicely. Well they got too big for the pots, so I put them in the ground. Will they bloom and produce a grapefruit?

If it was a store bought grapefruit, the fruit you get from the trees will be inferior to what you are use to. Store bought citrus grows on trees that are grafted so that they produce a better fruit. Yours is not, so the fruit will not be as good.

Beyond that, citrus trees can take up to 10 years to produce. It may be many years before you see fruit.

But, they actually make very nice houseplants. Just make sure they have enough water and sun and they are very lovely.
