Can I Grow an Orange Tree Inside?

I want to grow an orange tree in a pot indoors. Is this possible?

As long as you give it enough light, yes you can grow an orange tree inside. I keep my own orange tree indoors about half the year. The other half of the year, I place it on my porch.

Leaf Curling and White Spots on Fruit Trees

The leaves on our orange, lemon, lime, and grapefruit trees are curling up and have some white to brown patches on them. Others just dry up and fall off.

It sounds like your trees have citrus thrips. These can be a troublesome pest. This article can help:

Orange Trees With Yellow Leaves

I used to have a yard full of beautiful ornamental orange trees, guessing they are at least 10 years old. The leaves are turning yellow and they look terrible. Do I have a water issue? Is it some sort of disease? I don’t recall having this problem last winter, and they even survived the desert freeze. Please help, as these trees serve as a nice barrier between the the yard and ‘the other side’ of the wall.

When was the last time you fertilized the trees? They may need nutrients. If you have not been fertilizing, start doing so and, regardless, have the soil tested to see if you have any nutrient deficiencies that need to be corrected.

Trees in Containers

I have a small orange tree that I want to plant in a container. What is the minimum capacity (liters) for an ideal container?

ANSWERS

The minimum really depends on the plant. The rule of thumb is to make the container at least 5 cm larger than the rootball of the plant. Keep in mind that if you would like the plant to stay in the pot longer without having to be transplanted, you will want to make the container larger.

Dwarf Orange and Peach Tree

I have had the trees in containers for four years and have not had any fruit. The orange tree gets pea size oranges on it and then they fall off. The peach tree gets plum size real fast, but don’t get any bigger. I live in Las Vegas, so it gets very hot. Should I keep the plants in the full sun, or on the edge of the patio where I have them?

ANSWERS

It does sound like a watering issue. Shade will help keep the soil moist longer, but in your area, I would definitely be watering them 2X a day once the heat gets above 80F and 3X a day once the heat is over 100F. You may want to repot the trees in larger pots as well to help keep them watered well, or add a dish to the bottom to act as a water reservoir.

Just in case, I would also add some bone meal to add phosphorus to the soil. Sometimes fruit trees will drop their fruit if the phosphorus is too low.

Pruning Espalier Orange and Lemon Trees

I just planted two espalier trees: a Washington navel and a Meyer lemon. I have never pruned an espalier tree and need some information on how to do it. The trees were both seven-gallon trees. I planted them a week ago. Should they be fertilized now or should I wait a while? Any help you can give me on pruning and fertilizing would be appreciated.

ANSWERS

I would wait at least a year before pruning them. This will allow them to focus on establishing their roots system rather than healing wounds. Fertilizer is a good idea as that will help them get the energy they need to establish. In the meantime, you can keep the plants fertilized but start lightly, just to be safe--maybe half strength. Also, be sure to keep up with watering. This is very important to a tree establishing well.

When they are established, this article will help with pruning:

Leaves Falling of My Orange Tree

The leaves are falling off my orange tree, which is about 4 feet high and eight years old. What can I do to prevent this problem? The tree is blossoming now.

ANSWERS
Nikki

Typically this problem occurs due to inconsistent watering. It can cause confusion because a citrus tree will hold onto its leaves while not getting water and will shed them after water returns. Continue to make sure the tree is getting enough water. It may need additional water now that it is blooming.
