Soil

Loose, well-drained sandy soil is ideal. Avoid heavy or waterlogged soil, which rots the roots.

Watering

Water weekly while establishing; once established yuca is very drought tolerant.

Fertilizer Schedule for South Florida

Mix compost into the planting area and feed a low-nitrogen fertilizer (such as 4-6-8) once or twice during the season. Too much nitrogen grows leaves instead of roots.

Pruning

Little pruning needed; cut back to keep the plant compact. Save woody stem pieces to replant.

Cold Protection

Frost kills the top growth; roots may resprout. Harvest before a hard freeze in colder areas.

Container vs. In-Ground

Can be grown in a large 15-25 gallon container with loose mix, though roots will be smaller.

Spacing

Plant 3 ft apart in rows 3-4 ft apart.

Flowering and Fruiting Timeline

Plant in spring; roots are ready 8-12 months later, and can stay in the ground up to 18 months.

Harvest

Dig carefully around the base and pull up the roots. Use within a few days; roots spoil quickly.
