Position
Full sun in a spot that is sheltered from any cold snaps. Limes do not tolerate very cold temperatures well and will not thrive in places that dip to 10-degrees Celsius or below. If your garden is exposed to very cold conditions, plant your lime tree in a pot that can be moved indoors. Plant your tree with a space of at least 5 metres all around it.
Size
A sweet lime grows to over 2 metres. A seedling will take between 3 and 6 years to begin to bear fruit and reaches full production at 8 to 10 years old.
Soil Type
Lime trees thrive in warm soil that is well-enriched with nutrients; whether it is in a pot or the garden. However, the soil needs to have excellent drainage, as any residual moisture will threaten the survival of your tree. Pack the soil firmly around the roots when planting. Air around the roots will be detrimental to your plant.
Mulch
Citrus trees, in general, do well with an organic mulch that keeps the soil pH optimal and retains moisture. Use material like pine needles, leaves, straw or bark. It’s best to replace the mulch each time, rather than turning it into the soil (as this may disturb or damage the roots).
Watering
Water your lime tree frequently, every 7-10 days if it is in the ground and everyday if in container. They do better with regular sprinklings than with a heavy soaking.
Fertilising
Lime trees tend to feed quite heavily on the soil around them, depleting its natural nutrient content quickly. Use our slow-release nitrogen-rich all plant fertiliser Apply 1 teaspoon every 4-5 months.
Pruning
Lime trees are particularly easy to care for because they don’t require much in the way of pruning. However, for optimal condition, it’s wise to prune them at least once every year or two. This helps to prevent disease, strengthen the limbs and produce better, healthier fruits.
Harvesting
Your lime tree will likely produce fruit during summer, but some produce all year round. Pick the delicious sweet limes when they are yellow orange in colour.
