I just received my key lime tree. I ordered this tree as a valentines gift for someone and was expecting to receive a twig (as all reviews for other websites say they received). I have never been so pleasantly surprised!! The tree shipped very quickly (within a week) and is almost five feet tall!!! It already has fruit blossoms on it!!! Great great purchase! I hope everyone chooses to order their trees from this site. I truly am shocked by how great this tree looks! Best bang for your buck out there.

Wasn't too sure about ordering a tree online, but they had an incredible sale on this key lime tree so I decided to take the plunge.Well, I read the FAQ and it clearly states that west coast orders ship Sunday and Monday. I ordered on a Thursday and they shipped Friday. Unfortunately, it sat all weekend in the FedEx warehouse before making its way west. The tree dropped about two dozen leaves the first week and I was worried it wasn't going to make it.They did send a nice tree. I ordered a 3-4 footer and I received a 3 1/2 foot tree with lots of leaves and several branches. Even though it dropped a bunch of leaves it had plenty to spare.I'm happy to report it is doing extremely well now and I will probably order other trees from here in the future

I have four fruit trees from FGT; the key lime is one of the least successful. The tree is beautiful but I have had it for over one year and the tree has its first and only lime.

I ordered a lime tree for my fiance. I was nervous because I have had very bad luck ordering plants online in the past. He received a beautiful tree that was around 4 feet tall and was very full. The customer service of this company is wonderful. You cannot go wrong ordering your citrus trees from here! ( I ordered 2 more citrus trees for him for a late valentines and I cannot wait for him to get them! :-) )

Well the review for the Key Lime is similar to the Moro Orange I bought. In both cases I ordered a 3 - 4 foot tree. The tree arrived healthy and 54"" (4 1/2 ft) from soil line to highest lead. The tree is planted in a 10 gallon plastic pot in rich 'manufactured' soil like you use in garden beds. I was expecting sandy Florida type soil like you find in Orlando for some reason. I like eating limes and lemons like oranges and grapefruits, off the tree, so I hope it has a lot of fruit. The top isn't as 'bushy' as I had hoped but I imagine they prune them like this to grow them taller and also for shipping purposes. The trunk itself is about 3/4"" in diameter, straight, and sturdy.I plan to buy from Fast-Growing Trees a clementine, ruby red grapefruit (I'd buy the yellow grapefruit if they had them), a Meyer Lemon, and a Calamondin Orange

A happy tree!
This little guy survived the mountain summer with flying colors on the patio and has now started to grow like crazy since we moved him inside. It's a healthy and happy plant, and a fun family project.

My lime tree, bloomed beautifully and smelled awesome.... then died. I have no idea what went wrong. I was in the desert and couldn't find my order number so I couldn't get a replacement tree. I was very sad about the whole thing

I planted the tree in a huge pot because I have to put it in my greenhouse during the winder. The tree has put out new growth and appears to have adapted quite well to the pot . I water it once or twice a week and use a fertilizer for citrus plants on it. Also, I use a water soluble fertilizer for acid loving plants (citrus plants love an acid soil) on it once a month.

We received our key lime tree last week. It arrived in excellent condition. It is bigger than we expected and has lots of new growth coming on and even a flower is starting to bud. We live in VA and are looking forward to lots of limes!

Planting & Care

It's Easy to Plant & Care for Your Key Lime Tree

Key Lime Tree Planting Diretions

The Key lime tree (Citrus aurantifolia) makes an excellent houseplant, patio, or even landscape tree depending on what climate you’re located. Key limes do well outdoors in USDA growing zones 8-11. They can be planted in a full sun spot but if you’re in zones 10-11, offer the plant some afternoon shade to protect it from extreme heat. If you’re in zone 8, keep the plant in full sun. If your plant is containerized, keep it in full sun (8+ hours) during the spring and summer while it is outside. Supplement with a grow light while inside so that the plant gets the necessary 6-8 hours of bright, direct light. Reaching a mature height of 6-10 feet tall by 6-8 feet wide, they will grow at a rate of about 12-18 inches per year if in the ground. They will grow slightly slower if containerized as the roots do not have the same amount of room to grow, which will decrease the growth rate.

Selecting a location: Choose a spot where your tree is going to get plenty of sunlight, 6-8 hours per day is best. They can tolerate some shade in hotter zones, but thrive in full sun. These trees also do better in areas with high humidity so you may need to create some for your tree by misting the leaves daily with water. Potted plants do enjoy a daily misting for humidity but placing a tray with rocks filled with water under the plant will feed humidity to the tree as the water evaporates.

Planting Directions (in Ground): If you are located in zones 8-11 and your winter temperatures stay consistently warm, your Key Lime will do well being planting outside in the ground. Be sure the area has well draining soil.

1) Dig a hole twice as wide and just as deep as the root system.
2) Place the tree in the hole and back fill it with your sandy, well-draining, acidic soil. If you have clay soil, try amending it with sand, stone, perlite or fine potting soil.
3) Tamp the soil down as you back fill the hole to cut back on any pockets from forming.
4) After planting, be sure to give your Key Lime tree a deep watering until the ground is wet but not saturated. Mulching around the tree will help insulate the roots and keep your plant warm in the colder winter months as well.

Planting Instructions (potted): If your winter temperatures are consistently below 40 degrees, plant your tree in a container that can easily be brought outside in the summer months and inside in the winter. A planter with built-in casters is a good choice so it can easily be moved. Choose a pot slightly larger than what it was shipped in that has plenty of holes in the bottom to allow for drainage. Be sure to plant in well-draining potting soil preferably recommended for acid loving citrus plants.

1) Fill your pot halfway with soil. Remove the tree from it’s original pot and gently place it in the potting soil.
2) Fill in around the tree with the remainder of the potting soil but be sure not to cover the grafted area of the tree. Leave about an inch from the soil surface to the rim of the pot for easy watering.
3) Lightly pack down the soil. Immediately after planting, give your tree a deep watering until it flows from the holes in the bottom of the pot.
4) Place your tree in an area of your home, preferably a south-facing window, where it is going to get plenty of sunlight. Supplement with a grow light if it will not receive at least 6-8 hours of sunlight a day. You may also need to create humidity for your tree by placing the pot on a saucer of pebbles or misting the leaves daily with water.

Watering: Key Limes do not like wet feet. Be sure to give your tree a deep watering so that it can penetrate into the root system. After watering, allow the top 2-3 inches of the soil to dry out completely before watering again. Yellowing and droopy leaves is a common sign of overwatering while brown, dry leaves are a sign of under watering. Mulching can help retain the soil moisture and also combat competing grasses/weeds.

For potted Key Lime, stick your index finger into the soil down to about 2 inches. If there is moisture present, hold off on watering until it feels more dry at that depth. When ready to water, stop once you see it escaping the drainage holes at the base of the pot.

Pollination assistance: You can pollinate your indoor trees by hand since most people do not keep a healthy bee population within their home. Simply take a small, dry, fine tipped paint brush and stick it into the center of the bloom. Swirl it around and collect the pollen on the brush. Go to the next bloom and repeat the process until every bloom has been treated. Do this once daily and don’t wash the paintbrush until after the blooms have been pollinated. The bloom will fall of naturally and the fruit will begin to form.

Fertilization: Feed your Key Lime tree during the warmer spring and summer seasons with a citrus specific fertilizer once every six weeks. Espoma Citrus Tone is highly recommended but any organic fertilizer specifically for citrus should suffice. This will help keep your tree on a healthy growth cycle but also replenish the nutrients in the soil. During the fall and winter season, ease back to fertilizing once every 2-3 months. Once the tree has matured a bit and has got a few years on it, you can skip the cold season fertilization. The same fertilizing regimen should be followed for potted Key Lime trees as well. Make sure to follow the application instructions written on the fertilizer bag.

Pruning: Pruning can be done at any time of the year for in ground planted key lime trees, except in the winter. Make 45-degree angle cuts to remove dead or crossing limbs and also to thin out the tree to allow more light to flow between the branches. “Leggy” looking branches may indicate that there is not enough light getting to the tree’s interior. After the tree fruits, remove any dead wood and ventilate the center of the tree. Remove suckers as they form/grow from the base as they will steal away nutrients from the primary trunk of the tree. Pruning can be done at any time of the year for the potted Key Lime.

We've had much success with the Meyer Lemon tree (which we sadly lost last year due to an unexpected ice storm) so the lime presented another opportunity for a "You grew this" moment. FYI - it is doing very well so far!

I read the reviews and this tree seemed perfect for my back yard area. I have bought fruit trees in stores before and they did not catch on, so thought I would try purchasing through the mail from a company that had many good reviews. I live in florida and would love to walk into my back yard and pick enough limes to make a pie, or garnish a drink! I retire next year!

I have had my key lime tree for a couple of years. It flowers but no limes develop. Why?
Kathy G on Mar 14, 2015
BEST ANSWER: You might need to do some hand pollination. Here is a link to one of our blogs for instructions:
is the key lime tree self pollinating?
David H on Jan 16, 2015
BEST ANSWER: Yes they are self pollinating. The Key Lime Lime trees are self-fruitful, meaning their flowers contain both male and female parts, so they provide their own pollen. If kept indoors at all times we would suggest to hand pollinate.
Is this a thornless key lime tree.?...I googled thornless and this site came up, but it does not say that it is thornless.
Andria D on Mar 19, 2017
BEST ANSWER: The one I have for Florida has thorns.
Are the key lime tree resistant to deer?
Leroy B on Feb 14, 2017
BEST ANSWER: It is is deer resistant. However if food is sparse deer will eat anything.

Louis on Aug 23, 2016
BEST ANSWER: Yes they have seeds.
Why do citrus trees that grow in region 7/8 in TX, not ship to this area?

Do the limes produce seeds in them?
Shy G on Aug 14, 2016
BEST ANSWER: No, the Key Limes are seedless.
Why won't my lime bloom?
Mike k on Jun 29, 2016
BEST ANSWER: There could be a number of reasons why your Lime tree is not blooming. Could be a lack of nutrients or not getting enough heat/sunlight, improper watering. Sometimes with fruit, they just wont produce for a year, it could be environmental stress, or the tree could be reserving its energy for next years production.
Want to keep in pot. Do you offer Dwarf key lime? Or just keep it pruned?
