Dwarf Citrus Trees From "The Dirt On..." episode DTDO-118

Dwarf citrus trees are perfect for the gardener with a small backyard, just a patio or even no backyard at all. They stay about eight feet tall when full grown and are perfectly suited to grow in containers — even indoors.

Below, citrus expert Toby Seeger gives the scoop on how to grow these compact trees that produce full-size fruit.

Good drainage is essential for your potted citrus. If the pot you've selected doesn't have enough drain holes, drill more.

How do you plant these trees in a container?

First, you need to make sure you pick a container that's the right size, because you want the moisture to get to the tree, not just the surrounding soil. For a two-year-old tree, choose a container that's 10" to 14" wide. As the tree grows you'll have to transplant it to a larger container. Make sure the container offers good drainage. Turn the container upside down and drill more holes in the bottom if necessary.

The potting soil needs to be lightweight so it drains well. It helps to add cedar hamster shavings, available at pet supply stores, to the mix. That lightens the soil and makes it easier for water to drain though.

To plant, put an inch of soil at the bottom of the container and set your tree on top of it. Fill in around it with your new soil mix, making sure to plant it at the right depth. The top of the root crown should be just barely below the soil. Don't cover the trunk with soil.

How often should you water your tree?

Be consistent with your watering, keeping the soil moist but never soggy. A moisture meter is a great tool to help you out with this. You'll know exactly how much you need to water. If you notice wilting or yellow leaves, it may mean your tree is either under- or over-watered. Sometimes trees will start to drop their leaves or fruit if they aren't properly watered.

What changes should you make if you're going to grow your tree indoors?

Citrus can make great houseplants but they need to be near a window with direct light. They like eight to 12 hours of direct sun, so you may need to use grow lights if they can't get enough sun in your home. Although they can grow indoors all the time, they'll be most successful if you take them outdoors for the summer.
