Position
Full sun in a spot sheltered from the wind is best. 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 full-grown lime tree can be 5 metres tall and 5 metres wide. A seedling will take between 3 and 6 years to begin to bear fruit and reach full production at 8 to 10 years old.
Soil Type
Lime trees thrive in warm, moist soil well-enriched with nutrients, whether in a pot or the garden. However, the soil needs excellent drainage, as any residual moisture will threaten your tree’s survival. Pack the soil firmly around the roots when planting. The air around the roots will be detrimental to your plant.
Watering
Water your lime tree frequently, but conservatively. They do better with regular sprinklings than with a heavy soaking.
Mulching
Add a thick layer of pine bark mulch, keeping it about 20 to 30 centimetres away from the tree trunk (any closer may cause excess moisture and damage the trunk). This will retain soil moisture and prevent weeds from taking over.
Fertilising
Apply 1 teaspoon of our slow-release nitrogen-rich berry fertiliser 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 conditions, 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.
Pests and Diseases
Aphids, citrus psylla, red scale, citrus greening. Spraying regularly with Agricultural Neem Oil or Effective Microorganisms (EM Control) will assist in prevention or in after-the-fact control. If you already have aphids or mites, wash the tree with a harsh hosing, and when dry, spray with Neem oil or EM Control.
Practice good garden hygiene (remove fallen fruit and leaves).
Watch for root rot (if overwatered) and fungal infections during wet periods.
Harvesting
Your lime tree will likely produce fruit during the summer, but some produce all year round. Pick the delicious limes when they are a vibrant green and are juicy inside. By the time they turn yellow and wrinkled, they are over-ripe and bitter.
