Citrus × limon
Ever-blooming, self-fertile citrus that fruits year-round in warmth — or in a pot by a sunny window anywhere.

About lemons
Lemons are among the easiest citrus for a home orchard or a container: self-fertile, precocious, and quick to flower and fruit even while young. They need consistent warmth and cannot take hard frost, so outside the mildest zones they are grown in pots that spend summer outdoors and winter in a bright, cool room. Meyer lemon, a lemon-mandarin hybrid, is the most cold-tolerant and container-friendly type.
When to plant and harvest lemons
Timing is relative to your frost dates. Find your USDA zone for exact dates, or browse the month-by-month calendars.
Start seeds indoors
Not applicable — plant a grafted nursery tree; a seed-grown lemon takes many years to fruit, if ever, and will not come true to the parent variety
Transplant outdoors
Outdoors after all frost danger, once nights stay reliably above 50°F; container trees can move out for the frost-free season
Direct sow
Not applicable — nursery trees only
Harvest
Year-round in warm climates; often heaviest in winter

How to grow lemons step by step
- 1
Buy a grafted lemon tree — Meyer is the most forgiving for pots and marginal climates; Eureka and Lisbon are true lemons for warm-winter gardens.
- 2
Plant in the ground in full sun where frost never touches it, or in a well-draining pot sized to the rootball plus a few inches.
- 3
Water deeply when the topsoil dries, then let it dry again — citrus roots rot quickly in soggy mix.
- 4
Feed monthly through the growing season with a citrus fertilizer that includes micronutrients like iron and manganese.
- 5
Move potted trees outdoors for the frost-free months and back to the brightest indoor spot you have before nights drop near freezing.
- 6
Prune lightly to remove crossing or dead wood and to control size; lemons flower and fruit on new growth nearly year-round.
Common problems growing lemons
⚠ Leaves yellow between the veins
Usually a micronutrient deficiency (iron, zinc, or manganese) from cold soil or high pH — switch to a citrus fertilizer and warm the root zone.
⚠ Flowers or small fruit drop
Normal to a degree, but heavy drop often means underwatering, a sudden temperature swing, or a recent move indoors — keep watering and light as consistent as possible.
⚠ Sticky leaves with sooty black coating
Scale or aphids excreting honeydew, which grows sooty mold — wipe down leaves, treat with horticultural oil, and check the undersides regularly.
⚠ No fruit despite healthy growth
Young trees need time to mature, and indoor trees often lack pollinators — hand-pollinate open flowers with a small brush.

🧺 Harvesting lemons
Lemons do not ripen further once picked, so judge by color and feel rather than the calendar — a ripe fruit is fully yellow (or, for Meyer, deep yellow-orange) and slightly soft to a gentle squeeze. Clip rather than pull to avoid tearing the stem, and taste-test one before a big harvest, since fruit can hang ripe on the tree for weeks.
Lemons: frequently asked questions
When should you plant lemons?＋
In most regions you transplant outdoors after all frost danger, once nights stay reliably above 50°F; container trees can move out for the frost-free season. Timing is relative to your last frost, so find your USDA hardiness zone for the exact planting dates where you live.
Can I grow a lemon tree from a seed I saved?＋
You can sprout it, but expect years of waiting before it flowers, and the fruit likely will not match the parent since most citrus does not come true from seed. For real fruit within a few years, plant a grafted nursery tree instead.
Do I need two lemon trees to get fruit?＋
No — lemons are self-fertile, so a single tree will set fruit on its own with no pollinator partner needed.
