Citrus garden

There is something thrilling about growing a citrus garden at home. It almost defies nature. I think that's because when you think of citrus, you inevitably imagine a sunny oasis where citrus trees line an orchard and the fragrance overwhelms you with every step.

Create your own homegrown citrus garden

But citrus is sometimes grown where the climate gets a little colder. In these climates, the trees need to be brought inside until they are mature enough to keep them from getting too cold. So, yes, citrus trees are grown indoors. Let's take a look at how to start growing citrus from a seedling, how to grow citrus indoors, and finally, some interesting citrus garden fun.

Choose the seeds

Growing citrus from seeds is surprisingly straight forward, and something that anyone can do if they have a warm, sunny windowsill. You can either get citrus seeds through a gardening supplier or, even easier, collect your own from the citrus you eat. Choose organic, naturally grown citrus as you will eliminate the added chemicals, especially the ones used to prevent seed germination, which you definitely don't want when trying to sprout your seeds.

Cut the citrus open to expose the seeds. Remove the seeds and wash lightly. Place the ‘clean’ seeds into a bowl or glass of fresh water. This is in order to sort good seeds from bad seeds. Discard any seeds that immediately float to the surface or are cut or split, as these are not going to germinate. Once you have culled your seeds, they can be either germinated or dried and stored in a paper envelope until you're ready for them.

Time to germinate

Citrus seeds require a period of dormancy in cold temperature in order to initiate germination. To get your seeds 'in the mood' to germinate, you'll need to refrigerate them.

Prepare a little germination chamber by first laying the seeds on a paper towel, then fold the paper towel over the seeds, completely encasing the seeds inside. Now slip the paper towel into a ziploc plastic bag or airtight food container, then place in the produce drawer in your refrigerator. It should take about four to six weeks to germinate the seeds this way.

Time to plant

When you unwrap your germinated seeds, you'll see a little sprout. It's time to condition your seeds and prepare your pots. Put the seeds in cool, clean fresh water and allow to soak for a few hours. Meanwhile, prepare small pots, about 2 to 3 inch size, one for each seed. Choose a tray for draining that fits under the pots. If you have a somewhat sunny, not scorching hot, windowsill, a long narrow tray with several small pots works well.

Fill the pots with a handful of pebbles then a light, fluffy potting soil. Moisten the soil so it's damp, but not waterlogged. Carefully take each seed, sprout side up, and push a hole in the soil, then drop seed in, making sure most of the sprout is above the soil. Tap down lightly around the sprout and gently sprinkle a little water in each pot.

Watch the sunlight and water carefully. The sprouts need to be warm, not hot. The soil needs to be moist, not waterlogged.

The seedlings can be left in these pots until they are about 4 to 6 inches tall. Then you'll need to prepare bigger pots, but be sure to only go up one size. A plant that has too much room for the roots won't spend any time growing up. It will put all it's effort into growing more roots to fill the pot. You need a good amount of green leaves for your plant to mature, so you want your plant to grow upward and not just into more roots.

Your citrus plants grow up

Once your citrus plants are in their next size pot, you can start to 'harden off' the plant if weather in your area permits. This just means they can be moved outside to a sheltered area where they will get some warm, indirect sunlight and gentle breezes. Remember, they're still baby plants, so avoid hot sun and strong winds.

If you're ambitious, you can take the plants out daily, then return them to shelter overnight. It all depends on your weather and your set up. You will want to keep in mind your citrus plant's native lands when you consider the environment you give them. Citrus plants like warm days and cool nights, so try to mimic that for them.

When the plants appear to be toppling over in their pots, you'll need to transplant them again. Remember just to go up one pot size at a time. You may do this several times until your citrus plant has reached the desired size. Most people who grow citrus fruit at home choose small varieties of lemons and limes to start with because the plants are smaller and easier to handle.

Once your citrus plant has reached a healthy size, you can choose a spot outside for it to live during temperate seasons. During months where freezing weather occurs, you'll need to move your plants inside. You'll just need to make sure they get enough sunlight and water. You'll also need to research fertilizers and choose one that works for you to keep the plant nourished and fed.

Blossoms and fruit may not appear for several years. Don't be frustrated. Let the plant mature, keep it healthy, and you will be rewarded for your patience.

Indoor citrus gardening in a nutshell

Your very own citrus garden will take planning and work, but it's something you can do, even in very small spaces, and with very little experience. The following is an overview and a few tricks to help give you a citrus green thumb.

  • Pot plants correctly - A deep container, either clay or ceramic, works well. Citrus roots are fairly deep, so you'll need a pot that allows roots to grow down deep. Be prepare to have about 3 or 4 pots in progressively larger sizes on hand for the transplants.
  • Use a sterile all-purpose potting mix - If you can't find a potting mix designed especially for citrus, just make sure your potting mix is slightly acidic. Peat moss is a good additive to bring acidic levels up. If you're unsure, ask at any garden shop and they can help you. You can also add citrus rind peelings to the soil to get the acid levels up.
  • Give mature citrus trees a chilly bedtime - During the day, you want a warm location, but citrus likes to be chilly at night. A temperature around 50 to 60 degrees is good for a citrus tree's bedtime, but only after your citrus plant grows up.
  • Lots of the right light - A southeast facing window works well in most regions. The plant will get sunlight, but not get scorched, as they might in a southwest window. If you don't have enough natural light, think of adding plant lights to create a 'grow station.'
  • Maintain an evenly moist soil - Don't let the soil dry out between watering. Keep the soil moist, making sure you don't add so much water that the plant is sitting in a puddle. Stick your finger in the soil and if it feels dry more than an inch below the surface, add water.
  • Keep the humidity high - Citrus plants want a humidity level around 50 to 60 percent. Keep that in mind when you choose the location for growing your citrus tree. Mist your plants daily and group the plants together. This helps both to make it easier for you to mist your plants, and it also creates a little ecosystem where the plants are sharing their humidity with each other.
  • Pest control - The most likely pests are white-flies and spider mites. Insecticidal soap controls virtually all the pests for houseplants. Do the research and choose a method that works best for you and your environment.
