Lemon trees are generally hardy to the warmer parts of the country (to zone 7), and each growing zone has specific varieties best suited to the local growing conditions. Before selecting a variety, contact a local nursery or your state's Cooperative Extension Agency to get advice from experts on which varieties grow best for where you live. Agricultural commerce among various "citrus regions" is strictly regulated in order to avoid transmission of disease. This means you will generally buy your plants locally anyway, unless you are planning to grow them indoors.
All citrus trees, including lemons, like plenty of sun and heat, so if you live in the cooler edge of a variety's hardiness range, make sure to plant it in the sunniest, warmest, most protected part of the yard possible. If your area is very hot, some relief from the sun will be appreciate, especially at during the afternoon. If drying winds are a problem, consider protecting your tree with a windbreak.
Like other citrus trees, lemon trees prefer a soil pH that is lightly acidic-between 5.5 and 6.2. Many parts of the country feature alkaline soil, so unless you're growing trees indoors, it's wise to start with a soil test so you can make any necessary corrections well ahead of planting. Lemon trees can tolerate heavier soils, as long as they are well drained. They need ample amounts of moisture for growth, but they won't tolerate standing in water.
Because they bloom and produce all year round, lemon trees can be planted at any time of the year. Because the trees are almost always grafted, it's usually necessary to plant them a bit higher than they were growing in the nursery-ideally so that the graft union (usually seen as a diagonal scar near the base of the trunk) is between 4 to 8 inches above soil level. Water new trees thoroughly and keep a careful eye on moisture levels throughout the tree's first season.
Supermarket lemon trees: It's possible to grow lemon trees from the lemons you buy at the supermarket, but if the seeds are from a hybrid variety, they may not produce lemons, or the lemons may end up tasting quite different than the original. Some seeds will actually grow into productive trees, however, so it's worth a try! To plant the seeds you have saved from a supermarket lemon, follow these 6 easy steps:
Watering: Lemon trees planted in the ground have shallow roots that extend well beyond the drip line. Although they need ample moisture to maintain growth, it's okay to let the top 4 to 6 inches of soil to dry out a bit between watering. Too much water can be just bad as too little. Constantly saturated soil may stunt growth, encourage disease and affect the taste quality of the fruits.
Feeding: Citrus trees need a good supply of nitrogen. Trees growing in lighter soils will benefit from a top-dressing of compost and well-rotted manure several times a year. Container plants should be fed a liquid organic fertilizer that is higher in nitrogen than phosphorus or potassium (3-1-1, or 2-1-1). Apply according to label directions.
Weeding: Keep the area around the base of your lemon tree free of weeds. The roots of the trees are shallow and may not compete well with other plants-even grass. Use mulch to suppress weeds and conserve moisture, just keep the area within 6 inches of the trunk mulch-free. If gophers or rodents are a problem in your area, avoid using mulch as it gives them a good place to hide.
Pruning: Your lemon trees will not need much pruning. In fact, a good scaffold of branches and ample foliage will protect the fruit and lead to greater yields. As lemon trees mature they may need some light pruning to keep their form round and compact. Always remove any dead, damaged, or diseased wood as soon as you notice it. Container-grown trees may need to be root-pruned every few years to control growth.
Aphids, mealy bugs, and red spider mites can all attack lemon trees. They can be controlled to some extent by spraying with a strong stream of water or by using an organic, insecticidal soap. Fungal disease problems are much more prevalent in humid areas than they are in drier regions. Good cultural practices are the best way to prevent these diseases. Start with disease resistant root stock planted in quality soil with good drainage. Keep your landscape clean by destroying all plant debris and cutting off suckers as they emerge from the roots.
Lemons can be harvested year round, but like all citrus trees, they must be fully ripe on the tree before you pick them. It is sometimes hard to tell if lemons are ripe, but they should look bright yellow and smell lemony. If you have to work too hard to remove a lemon from the tree, it's probably not ripe yet. Lemons will keep quite a long time hanging in the tree, so there's no urgent need to pick them until you're ready to use them.
Lemon trees make fine container plants, especially in cooler climates. Grow them as small trees in containers on your patio in the summer, and move them to a sunny spot indoors to spend the winter. Their growing needs are the same as lemon trees grown in the ground-plenty of sun, the proper amount of moisture, and good drainage. Plants growing in pots should be put on a fertilizing schedule to ensure that they get consistent nutrients.
Containers should be as deep and wide as you have room for (bigger is better), and should be placed on castors to make moving heavy pots outdoors as easy as possible. In spring, move them into partial shade first before exposing them to bright outdoor sun. In fall, do the reverse. Give them a bit of shade before moving them back inside to minimize the shock. Indoor air can be dry in the winter, so keep plants on a pebble tray or mist them regularly to maintain some humidity.
Lemon trees grown in containers are much more susceptible to cold and drought, so keep an eye on temperatures and moisture. Because these trees are almost always grafted, the main root stock may eventually send up suckers to try to overtake the tree. If you see suckers coming up from the base of the trunk, remove them with a clean pruning shears as soon as possible. Popular indoor varieties include, Meyer Improved Dwarf, Lisbon, and Ponderosa Dwarf.
I am planning on planting a Lemon Tree this spring - good to know that they produce year around. I tried Grapefruit and am just now picking them and they are wonderful. Hoping Lemons will be good also.
This is a guide about growing lemon trees from seed. Growing fruit trees from seed is fun, despite the long wait for them to reach maturity.
We brought our small Meyer lemon indoors because it was getting colder out. It seems to think it's spring because it started flowering right away.

I love how you can see the green fruit along with the white flower. I wonder if it will ever turn yellow. :)
Has anyone out there ever grown a lemon tree from seed? I have heard it is done in Siberia. If they can do it, surely we can. Will supermarket lemons give good seed? Should I just buy a started tree? I now have a nice, sunny window and have wanted to give this a try since forever!
By Coreen from Rupert, ID
It is possible, I've done it and had mixed results. I don't have a green thumb but wondered the same thing one day about growing a lemon tree. All I did was remove a few seeds from a grocery store lemon, put two seeds in each of two pots with potting soil.
Eventually they sprouted and I gave one to my sister. Hers really took off and today (years later) is a six-foot tree and it has always been in the house. Mine reached a few inches in height and then died. Don't know what happened! Both were kept in sunny windows. Give it a try. It's a fun experience. I was really proud of myself (til it died!). And now you've inspired me to try again. Good luck!
I have a lime tree and I keep it outside in the summer and bring it in in the winter. It is not real fast growing and I have never gotten a lime from it. It also has sharp thorns on it. The leaves get real dark and glossy so it is a pretty plant whether or not it produces fruit.
Hi, I have sent lots of links chock full of information on planting lemon seeds.
Remember if you want to clean your own potting soil, heat it to 160 degrees in the oven and keep it that way for 30 minutes once the soil is heated to that degree. Or you could just buy potting soil. You can have good results with paper towels and a baggie.
I love to plant seeds. Here are some ways to plant lemon pits and grow them.
First you wash the seed, very well, very well washing the seed (notice how I wrote that two times...) NOT letting it get dried out. Lemon seeds will not tolerate being dried out....like being left in your purse on the way home from the fast food joint.Other seeds can can be dried, not so with lemon seeds.
You might choose to plant the lemon seed in soil a half inch deep in a styrofoam cup of potting soil with holes a plenty punched in the bottom for drainage, or place immediately in between two folded paper towels and keep moist.
You can put them in a baggie or on a plate in a warm spot like the top of a refrigerator but not too warm where it would dry out. If they dry out they are done for. Did I mention how a lemon seed will not sprout if it is allowed to dry out?
You don't need to have light until the seed sprouts.
Of course, if there is any sugar on the seed and you plant it in the soil the sugar will cause a problem and kill the plant.
Keep the lemon seed moist at all times, but remember the cup and soil must have drainage holes at the bottom. This is a good way to recycle styrofoam cups into something useful.
Without drainage holes in the cup, the seed would be attacked by fungus which would kill the seedling when it sprouted or before.
Once they do sprout give them several hours of bright light, or direct light each day. It does not have to be direct light.
They need to be replanted into soil once they sprout if you are using the baggie method.
I have also included some links to online nurseries with information on planting lemons from pits. It takes about 15 years to grow fruit from seeds which you plant yourself.
I like to have homemade plants too. I enjoy planting pits of avocados, and such.
Some of the seeds from fruit require a cooling off period if I am correct, but I have not found the need to do that for lemons. Someone can correct me if I am wrong.
Check out the links below for fun things like drawing a face on a recycled styrofoam cup, poking holes in the bottom, and putting potting soil in it and planting grass seed. You can give this little " plant person" a hair cut as the grass grows....Is that not the cutest idea?
Also, you can plant the tops of carrots between two toothpicks in a glass of water. The bottom part without the leaves goes in the water.
(This is the same way to peel an avocado seed and put three toothpicks in it and sprout it also. I sometimes do not peel mine. It helps to peel them though. On avocado seeds there is a paper like covering around it once it is dry you can peel it off.)
I used to order plants all the time from a different nursery, but I forget which one it was.
The link below to the online nursery is a great place, too. Have fun researching all these links! Here they are below, I have looked at them all:

And remember do not let your lemon seeds dry from the time they come from the lemon to the time you wash and plant them or put them in paper towels and a baggie or they won't grow at all.
I am working on this now in Oregon and it took off really well with the sunny weather we had. Now it seems to have stopped growing, but is very green, looks healthy and has 6 leaves on it. I am being patient to see what it does next. It's on the window sill with my orchids that are just thriving.
Amazingly enough, I happened upon an idea of what to use to feed my Meyer lemon tree in a large pot. I use the cold beet liquid that remains after you cook beets on top of the stove in boiling water. Make sure to water it only with the beet water at room temperature! My lemon tree loves it, and thrives with very dark green leaves, and it produced 8 large lemons this year! I also put it outside in our very hot side of the house for the summer! I live in Olympia, Washington, believe it or not!
I tried to fix my previous post. Do not feed your lemon tree beer- my stupid spell check put beer instead of totally cooled down to room temperature beet root water left over after cooking cooking your beers on top of the stove.
I have a Meyer lemon tree planted in a container that I keep outdoors. It has bloomed and produced plenty of lemons for the last 4 years. Earlier this year it bloomed and small fruit started to appear. We have experienced extremely hot weather, but I made sure the tree was properly watered. Eventually, the majority of the leaves, blooms, and small fruit fell off the tree. It did recover and is fully covered with beautiful green leaves but no fruit. What happened and what should I do?
By Willie B.
That usually means it was over watered. If it has rocks in the bottom for airiation and a hole, make certain it is on something where the excess water can drain and is in enough light to help the dirt to dry and it may get new leaves. Good luck. Don't feel bad, we've all done it.
Sorry, my bad, I didn't see your whole post. Wait a while, fertilize (sic?) and it should bear fruit the next season. It's on the mend.
I live in south georgia and I own a meyer dwarf lemon and the lady is correct on the too wet. Be sure you have good drainage and I planted mine in decomposed pinebark mulch and potting soil. I placed it in the sun and it got water each day or so but the bark held too much water so I repotted the plant got it right and it started to grow leaves now you can start to feed it and it keeps blooming and bearing year round if you don't freeze where you are. If too cold it will drop fruit, if you over feed it will drop fruit, too wet of soil, and otherwise it will bear year round. I place mine in a window in the winter sun shines in and it keeps on bearing. In winter less water is the key, only when dry or almost dry. The same in summer.
How do I cure scale on my lemon tree?The branches have a green slime and a fungal scale 30mils in diameter on average is present on the branches.
Try the extension office website for your area to get good advice on this. There are several commercial fungicides specifically for citrus trees too, have a wander through the chemicals section of a good quality plant nursery or garden centre in your area.
To find the extension office website for your area, Google the name of the nearest university along with the words extension service. The advice there is free, printable, and geared specifically to your location.
Frugal is correct. The extension service will give you the best advice. I have had scale on a few plants and it is very difficult to eradicate. But they will give you the best advice.
My lemon tree is having problems with it's leaves curling. Anyone have any ideas what is causing this and what to use to eliminate it? What is the best stage to pick the lemons?
