Oranges are best ground outside for the best size of the fruit. However, they will most likely die in a period of frost. So in colder climates, you will need to grow your oranges indoors during winter, early spring, and late autumn. If you check a frost calendar for your area you can then see when you can put your orange plants outside for the summer. Usually, this will be around May for UK or places of a similar climate. If you live in a warmer climate with very little chance of frost you can keep them outside for the whole of the year. A consideration to make is that a orange plant will grow to be around 3 - 5 feet tall. This means it may be ,difficult to move around frequently. An ideal area to grow orange trees indoors would be a bright and airy conservatory or heated greenhouse.

Citrus trees such as lemons, limes, oranges and graprefruit prefer being in the full sun. In most of the United states they can be grown outdoors. In more northern states and countries similar to the UK they can be grown better inside heated greenhouses or conservatories. They can also be taken outside in summer.

You can tell when citrus are ripe from both their colour and with some the softness of the fruit. When they are growing all citrus will be green. Oranges become orange as they get ripe. You will also be able to tell when Oranges are ready and ripe by the softness of the fruit. They soften over time as they become ripe.

Growing tips

Try to keep atmosphere temperature above 50 degrees farenheight.

To fully fruit they will need to be pollinated and if they are growing outdoors animals such as bees will pollinate without you having to do anything. If you keep them indoors you will need to pollinate the plants yourself.

They also need full sunlight to fully develop large fruit. If it is impossible to grow outdoors consider a grow bulb on a 16/8 rotation 16 on and 8 off. Oranges can flower and fruit all year round and the fruit can take up to 12 months to ripen.

Oranges are very nutrient hungry heavy feeders and should be fed a nitrogen-heavy fertiliser during summer. This is important as the plant may start to cannibalize itself when undernourished. They also prefer slightly acidic soil. A fertilizer such as ammonium nitrate is wise. You can also use peat or ammonium sulphate. There are a number of slow release fertilizers on the market that you can buy to reduce time spent replenishing feed.

These plants are usually brought as small bushes or small plants. Keep in mind they can grow up to 3 - 5 feet tall and will need a large pot to maintain a healthy root system.

It is important to keep the root ball healthy and avoid root rot. This will damage or even kill your plant. To combat this try not to overwater and use a healthy soil compost with a water absporber such as perlite.

When they start to produce fruit make sure they get extra sunlight, especially in spring and summer. This is especially important if you are growing citrus indoors.
