What Are Clementines?
Clementine oranges, also known as mandarin oranges, are small, sweet oranges that are native to China. They are sometimes called Christmas oranges.
The mandarin orange (Citrus reticulata), also known as the mandarin or mandarine, is a small citrus tree fruit. Treated as a distinct species of orange,it is usually eaten plain or in fruit salads. Tangerines are a group of orange-coloured citrus fruit consisting of hybrids of mandarin orange with some pomelo contribution. https://en.wikipedia.org/wiki/Mandarin_orange
They are believed to be a cross between a sweet orange and a tangerine and are named after a French monk, Father Clément Rodier, who is credited with introducing the fruit to the Western world in the late 19th century.
In terms of appearance, clementine oranges are small and round, with a thin, bright orange skin.
They are typically smaller and less acidic than regular oranges and are known for their sweet, juicy flesh.
The bright orange fruit is easy to peel and is often seedless, making it a convenient and popular choice for snacking.
Clementine oranges are commonly used in salads, desserts, and as a garnish for cocktails. They can also be juiced or used in marmalades and preserves.
The fruit has a sweet, tangy flavor that is similar to a tangerine, but slightly less acidic.
Overall, clementine oranges are a popular choice for their sweet, juicy, and convenient nature.
How To Grow Clementines Indoors
Growing clementine oranges indoors is possible. However, to succeed in growing clementine oranges indoors, you’ll need to provide the tree with the right conditions.
They are not difficult to grow but they do need a lot of light so you may need an LED grow light even if you do have a sunny window.
How to grow clementines without seeds
You don’t want to try growing indoor citrus from seeds. The plants will be too large and the fruit may not be true to the parent variety.
For this reason, you want to be sure to buy a grafted citrus tree,
They are small trees and can be bought grafted onto a dwarfing rootstock called Flying Dragon which will keep these fruit trees very manageable.
Make sure not to bury the graft union when planting a dwarf variety. I recommend buying a grafted tree. Seedlings are variable and may not even produce clementine fruit.
Clementine Tree Care Indoors
According to information online, Clementine oranges can be kept outdoors in USDA hardiness zones 8-11.
But I think zone 8 with lows of 10-20 degrees is really too cold. They need warmer climates and I would only keep them outdoors in zone 9 and above.
Clementines should not be kept outdoors in colder climates unless you are prepared to bring them indoors when it freezes.
Here are some tips for growing clementine oranges indoors:
Choose the right pot: Clementine oranges need a pot with good drainage and a well-draining soil mix. The pot should be at least twice the size of the root ball to give the tree enough room to grow. It should have drainage holes
You can place some pebbles in the bottom of the pot to help drainage. Always remove excess water from the plant’s tray to prevent root rot.
Provide plenty of light: Clementine oranges like most other citrus can grow in full sun. They need bright, indirect light in order to thrive. You may need to use grow lights to supplement the natural light in your home.
Water regularly: Clementine oranges need to have their soil kept consistently moist, but not waterlogged.
Always use well-drained soil for your young trees. You can use a moisture meter to check the soil moisture levels and water as needed.
Fertilize regularly: Clementine oranges need to be fertilized in order to grow and produce fruit. Use a balanced citrus fertilizer according to the instructions on the package.
Prune and train the tree: Pruning and training your clementine orange tree can help it grow into a healthy and attractive shape.
Remove any diseased or damaged branches and prune off any branches that are growing too long or out of place.
You can also use stakes or trellises to train the tree to grow in a specific direction.
How long does it take for a clementine tree to bear fruit?
It can take a clementine tree anywhere from 3 to 5 years to start producing fruit.
However, this time frame can vary depending on a number of factors, such as the tree’s variety, growing conditions, and overall health.
In general, citrus trees grow relatively slowly, so it is important to be patient and provide the tree with proper care and maintenance as it matures.
With proper care, your clementine tree should start producing fruit within a reasonable timeframe.
Citrus Pests
There are some pests to keep an eye out for but they are less likely to occur growing citrus indoors. Still keep an eye out for bugs.
Here are several pests that can bother clementine oranges, including:
Aphids: These small insects feed on the sap of citrus trees, and can cause leaves to yellow and curl.
Citrus thrips: These tiny, slender insects feed on the leaves and fruit of citrus trees, and can cause scarring and discoloration on the fruit.
Citrus mites: These small, spider-like pests feed on the leaves of citrus trees, and can cause leaves to yellow and drop off. Spider mites are a common indoor pest.
Citrus leafminer: This insect lays its eggs on the leaves of citrus trees, and the resulting larvae burrow into the leaves, creating distinctive, winding mines.
Citrus psyllids: These small, winged insects feed on the new growth of citrus trees, and can cause leaves to curl and distort.
If you notice any of these pests on your clementine tree, there are several control measures you can take, such as applying insecticidal soap or horticultural oil, introducing natural predators, or removing and destroying infested plant parts.
It is important to carefully follow the instructions on any pest control products you use and to take care not to harm beneficial insects or other non-target organisms.
Do dwarf clementines fruit sooner?
Dwarf citrus trees, including dwarf clementine trees, tend to be smaller and more compact than their full-size counterparts.
As a result, dwarf citrus plants may start producing fruit at a slightly earlier age than full-size trees.
However, it is important to note that dwarf trees can still take several years to start bearing fruit.
About chilling hours
Clementine trees, like many other citrus trees, have a requirement for a certain number of chilling hours in order to produce fruit.
Chilling hours refer to the number of hours that a plant is exposed to temperatures between 32 and 45 degrees Fahrenheit during the winter months.
This period of cold temperatures is necessary for the tree to break dormancy and resume growth in the spring.
The number of chilling hours required can vary depending on the specific variety of clementine tree.
Some varieties may require as few as 300 chilling hours, while others may need up to 500 or more.
If you are growing a clementine tree indoors, you may need to artificially provide the tree with sufficient chilling hours.
This can be done by exposing the tree to cool temperatures for a set number of hours each day.
You could try moving it outdoors for short periods when temperatures are above freezing or you might find a semi-heated garage or basement for it temporarily. 500 hours is about 3 weeks.
Are clementines self-fertile?
Most clementine varieties are self-fertile, which means that they do not require another variety of citrus trees for pollination in order to produce fruit.
However, it is still a good idea to plant more than one clementine tree in order to increase the chances of successful pollination and fruit production.
Additionally, some clementine varieties may produce more fruit when they are cross-pollinated with another variety of citrus tree.
If you are growing clementine trees indoors, you may need to manually pollinate the flowers in order to increase the chances of fruit production.
This can be done by using a small paintbrush or cotton swab to transfer pollen from the stamen (male part) of one flower to the pistil (female part) of another flower.
How do you hand-pollinate clementines indoors when there are no bees?
To hand pollinate clementines indoors, you can use a small paintbrush or cotton swab to transfer pollen from the stamen (male part) of one flower to the pistil (female part) of another flower.
Here is a step-by-step guide on how to hand-pollinate clementines indoors:
Identify a flower that is in the process of blooming. Look for a flower that has a swollen ovary and a protruding pistil, but no visible pollen on the stigma (the top of the pistil).
Locate a flower that has recently opened and has visible pollen on the stamen (the male reproductive organ).
Use the paintbrush or cotton swab to gently collect some pollen from the stamen of the second flower.
Transfer the pollen to the stigma of the first flower, making sure to coat the stigma with a generous amount of pollen.
Repeat the process with additional flowers as desired.
Keep in mind that hand pollination is not a substitute for natural pollination by bees or other insects, and may not be as effective.
However, it can still be a useful technique to increase the chances of fruit production in an indoor setting where pollinators are not present.
