How to Grow Citrus Trees

Updated: Jul 29

Thinking about growing your own citrus trees? That’s a fantastic idea. Citrus trees not only give you delicious fruits but also add a wonderful fragrance to your garden. Whether you’re into oranges, lemons, limes, or grapefruits, growing these trees can be a truly rewarding experience. Let’s walk through the process of growing citrus trees together, from planting to pruning, with some interesting tidbits along the way.





First things first, picking the right citrus variety is key. Are you more into sweet oranges like Navel or Valencia? Or perhaps you’re a lemon lover, with Eureka or Meyer lemons on your mind? Meyer lemons are especially popular because they’re a bit sweeter and less acidic, making them perfect for all kinds of recipes. If you like a little heat, Persian limes might be your go-to. And let’s not forget about the incredibly sweet and easy-to-peel Satsuma mandarins!


Make sure that the tree you pick is climate appropriate for where you live. If you see colder temperatures, you might need Arctic Frost Satsumas for oranges. Maybe you need to move them inside when it's cold. Consider dwarf varieties.


Once you’ve decided on your citrus variety, it’s time to think about where to plant it. Citrus trees love sunshine, so pick a spot that gets at least 6-8 hours of direct sunlight each day. Well-drained soil is a must since they don’t like their feet to stay wet. If you’ve got sandy loam soil, you’re in luck—citrus trees thrive in it. And hey, if you’re in a cooler area, plant your tree near a south-facing wall to give it some extra warmth and protection from the frost.


Now, let’s talk about planting. You’ll want to start by preparing the site. Clear out any weeds and debris, and dig a hole that’s about twice as wide and just as deep as the tree’s root ball. When you take your tree out of its container, gently loosen the roots before placing it in the hole. Make sure the top of the root ball is level with or slightly above the soil surface. Fill the hole back in, firming the soil around the roots to eliminate air pockets. A thorough watering will help settle everything in.


 

Here’s a fun fact: Did you know that citrus trees have been cultivated for over 4,000 years? They originally come from Southeast Asia and were spread across the world by traders and explorers. Imagine the history you’re continuing by planting your own tree!

 

Once your tree is in the ground, it’s time to focus on care. Citrus trees need consistent moisture, especially when they’re young and during fruiting. Water deeply but let the soil dry out a bit between waterings to avoid root rot. Mulching around the base of the tree helps retain moisture and suppresses weeds, but keep the mulch a few inches away from the trunk to prevent rot.


Feeding your citrus tree is also important. These trees are pretty hungry and benefit from a balanced fertilizer high in nitrogen. A good rule of thumb is to fertilize three times a year: early spring, late spring, and late summer. This keeps them happy and productive. Just make sure to follow the package instructions for the right amount based on your tree’s size.


Pruning might sound intimidating, but it’s not too hard. The best time to prune is late winter or early spring, just before new growth starts. Start by removing any dead, diseased, or crossing branches. This helps with air circulation and light penetration, which are crucial for healthy growth. If your tree is getting too tall, cut back the tallest branches to an outward-facing bud or lateral branch to control its height.


Speaking of pruning, did you know that some of the oldest citrus trees are over 100 years old? They’ve been pruned and cared for through generations, producing fruit year after year. With the right care, your tree could be around for a long time too!


Now, let’s talk about pests and diseases. Aphids, scale insects, and citrus leaf miners can be common pests. Regular inspections and treatments with insecticidal soap or neem oil can keep these critters at bay. For diseases like citrus canker or root rot, proper site selection and good watering practices are your best defenses. Keeping the area around your tree clean and free of fallen leaves can also help prevent disease.


When it comes to harvesting, patience is key. Citrus fruits can take several months to ripen. Oranges and mandarins are usually ready in winter or early spring. Lemons can be harvested as soon as they’re fully colored, and limes are often picked green. Gently twist or cut the fruit from the tree, leaving a small stem attached to avoid damaging the fruit.


Here’s another fun fact: The sweet smell of citrus blossoms is not just pleasant for us but also highly attractive to bees. These bees are crucial for pollination, helping your trees produce even more fruit.


Growing citrus trees isn’t just about the fruit—it’s also about enjoying the journey. Watching your tree grow from a small sapling into a mature, fruit-bearing tree is incredibly satisfying. Plus, there’s nothing quite like picking a fresh lemon or orange from your own backyard.


Whether you’re starting with a single tree or planning a mini orchard, remember to take it one step at a time. Enjoy the process, and don’t be afraid to experiment and learn as you go. Your citrus tree will reward you with beautiful blooms and delicious fruit, and you’ll have the satisfaction of knowing you grew it yourself.
