Description
LSU Purple is an often-overlooked fig variety, mainly because it struggles with dry soil—while the fruit won’t drop, it may fail to ripen properly. However, once the tree matures after a few years, this sensitivity becomes far less of an issue.
LSU Purple figs ripen earlier than most, making them a reliable choice for those eager to enjoy their harvest sooner. This variety is fairly rain resistant and do not split as easily as most. This variety is robust and well-suited for warmer climates, making it a valuable addition to any garden.
Position
Choose a sunny location with full sun exposure—fig trees need at least 6 to 8 hours of direct sunlight daily.
Space trees 3 to 5 metres apart to accommodate mature size and ensure good air circulation.
Plant at the same depth as in the nursery container. In colder regions, protect the base with mulch and cover the tree with frost cloth when necessary. For potted figs, move them indoors to a cool, sunny spot during cold spells.
Soil
Figs thrive in well-draining soil—loamy or sandy loam is ideal. They do not tolerate waterlogged conditions.
Incorporate compost or other organic matter to improve drainage and support strong root development.
Add organic matter such as compost to improve soil drainage and ensure good soil structure for root development. Adding half a bag of our Volcanic Rock Dust and a bag of Superfrass will assist in rapid growth. They also protect the roots from insects.
Watering
Keep the soil consistently moist after planting, but avoid overwatering. Water deeply once a week, letting the top few centimetres of soil dry out between waterings.
Once established, water only when the top 2–5 cm of soil feels dry. Reduce watering during cooler months. Avoid excessive moisture, which can cause root rot.
Mulching
Apply a 2–5 cm layer of pine bark mulch to retain soil moisture, protect roots from heat, and help maintain pH levels.
Keep mulch away from the trunk to prevent rot and infection.
Fertilising
For young trees use our slow-release, Berry/All-plant fertiliser. Apply 1 teaspoon every 4–5 months. The plant will absorb nutrients as needed.
Pruning
Prune to control size, shape, and overall health. Remove dead or diseased branches and any that grow inward toward the centre.
Best done in late winter or early spring before new growth appears. Light summer pruning can help improve fruit quality and manage shape.
Pests & Diseases
Common pests include aphids, scale, and fruit flies. Check regularly and treat promptly if needed.
Figs are also prone to fungal issues like rust, leaf spots, anthracnose, and root rot—ensure proper spacing and avoid overwatering to minimise risk. Its unique resistance to root-knot nematodes further enhances its appeal among fig cultivars.
Fig Mosaic Virus is a benign virus that exists in all cultivated fig trees. Yellow spotting of the leaves is a cosmetic symptom that shows more in container culture, but is quickly outgrown once trees are planted in the ground.
Use Agricultural Neem Oil or Effective Microorganisms (EM Control ) for prevention and treatment. If aphids or mites are present, spray the tree with a strong stream of water, let it dry, then apply Neem or EM Control.
Harvesting
Figs are ripe when soft, fragrant, and slightly drooping. Harvest gently by twisting or cutting them from the tree—handle with care, as they bruise easily. Figs typically ripen from late summer to early autumn.
