How big do citrus trees grow?
I want to grow a citrus tree indoors, how high do they grow?
1. Some are only a couple of meters. I've climbed an orange tree that was like 25 meters before.
2. About 6 to 8 feet.
3. It would depend on the variety but they are slow growing and would give many years of enjoyment before you need dispose of or sell it!
4. here in Hawaii at my house we have 2 citrus tree's. they are about 6-7 feet tall. pretty wide but this is because we do not trim them or anything. take into consideration these tree's are not properly fed fertilizer on a set schedule. if it was fed i would assume it could get bigger and produce more fruit as well.
they are both orange tree's not sure what kind though. we also got a tangerine tree but it's pretty small only about 1-2 feet tall. these are not my plants my dads
5. Don't count on your tree to get anymore than 4ft to 5ft best indoors under average indoor culture.
In these conditions they turn into bonsai. LOL
If you put it in say a nice bright sunny warm greenhouse you depending on the greenhouse's size you can expect 12ft to 20ft tall!
Also other factors like species, cultivars, and rather the plant is grown on it's own roots or grafted will also affect size. Ponderosa and meyer lemons grow the largest while mandarin oranges grow the smallest as do dwaft and compact cultivars.
6. Here is a reference to a book that was written by a backyard citrus enthusiast who lives in Great Britain. If you can find a copy of this book it will answer a lot of questions for you.
Page, Martin. Growing Citrus: How to Grow Citrus Trees in Containers,
Conservatories and in the Open Garden.
Portland, OR: Timber Press, 2008. 193 pp.
At long last, we have a citrus book more focused on container culture in sunrooms, windowsills and greenhouses than outdoors in the ground. The author, Martin Page, is an ecologist and a citrus hobbyist in the United Kingdom. The truth is that there are not all that many tropical fruits that grow well indoors or in small greenhouses, but the smaller citrus varieties do beautifully in such environments and they are actually reliable producers of fruit under these conditions. More and more people in cold climates are discovering how decorative and fragrant these trees are and how rewarding it is to grow them.
The first part of the book covers the origins and history of the various citrus fruits, their botany and taxonomy, economic uses, soil and nutrition, different types of containers, fertilizing, the peculiarities of growing citrus trees in different environments, as well as pests and diseases. The second part of the book is a detailed encyclopedia of the various citrus varieties. In this section, Page describes the major cultivars of sweet oranges, sour oranges, mandarins, tangerines, clementines, grapefruits, lemons, limes, citrons, kumquats, calmondins, limequats, tangelos and others, pointing out those which are unsuitable for container culture. The last chapter deals with citrus rootstocks used in propagation. It is followed by appendices of frequently asked questions, a glossary of terms, a description of the major citrus collections in Europe, Australia and the United States that are open to the public, and a brief listing of suppliers of citrus plants, planters, fertilizers and other products in the United States, Europe, Australia and New Zealand. A bibliography of sources and an index are also provided.
This book is one of the best sources of information on the indoor/outdoor growing of citrus in colder climates. The author has an accessible, nontechnical, easy to read style. Unbelievably, I read most of it on the treadmill at the spa. Most specialized plant book just don’t lend themselves to reading while exercising!
The only minor quibbles I have with the book are a certain lack of precision in the discussion of citrus nutrient deficiencies and an overdependence on pesticides (The British names and products wouldn’t help us much anyway!). What is wrong with ultrafine horticultural oil? It works well on citrus. Remember, these plants are located where you live. That’s the air you are breathing day in and day out. Even if it’s in a greenhouse, you are in there a lot, so it makes sense to steer clear of pesticides.
All in all, this book is highly recommended for all who grow citrus indoors and in greenhouses. Most other books out there aren’t of much help when you grow in containers.
