How to plant it
General steps for this plant. Save a garden and these become specific to your location, soil and light.
Step 1When to plant
Plant during March to May, once the risk of frost has passed.
Timing depends on your last frost date.
Step 2Where to put it
Choose a position in full sun for most of the day. Allow 2.5 m of room around it — mature spread is 2.5 m and mature height 2–4 m.
Light in your garden is not answered, so this is the plant's own requirement.
Step 3Preparing the ground
Dig a hole twice as wide as the root ball and no deeper, loosen the sides, and plant so the top of the root ball is level with the surrounding soil.
Soil is not answered. This plant grows in average conditions.
Step 4Watering while it establishes
Water thoroughly at planting (5–10 litres), then only when the top few centimetres of soil are dry, through the first growing season.
Even a drought-tolerant plant (3/5 here) only becomes drought-tolerant once established.
Step 5Mulch
Spread 5–7 cm of composted bark or garden compost around the plant, keeping it clear of the stem.
Mulch cuts water loss and suppresses weeds through the first summer, when losses are most likely.
Step 6The first year
Check watering weekly in summer, remove competing weeds, and tidy dead growth at the end of the season.
Maintenance level on the plant record is medium.
Step 7What to watch for
Frost-tender; needs feeding and free drainage.
Taken from the plant record and your measured climate figures, not from a general description.
Spacing: about 2.5 m apart — roughly 2 plants for every 10 m² if planted as a group.
What this guide could not use
- No location saved, so planting times are general rather than local.
- Soil moisture is not answered, so soil preparation is general advice.
- Light is not answered, so the position below is the plant's own preference.
- Whether you can water is not answered, so watering assumes hand watering.

The lemon (Citrus × limon) is a species of small evergreen tree in the Citrus genus of the flowering plant family Rutaceae. A true lemon is a hybrid of the citron and the bitter orange. Its origins are uncertain, but some evidence suggests lemons originated during the 1st millennium BC in what is now northeastern India. Some other citrus fruits are called lemon. The yellow fruit of the lemon tree is used throughout the world, primarily for its juice. The pulp and rind are used in cooking and baking. The juice of the lemon is about 5–6% citric acid, giving it a sour taste. This makes it a key ingredient in drinks and foods such as lemonade and lemon meringue pie.
