Expert tips
The key tip
Very well-draining, preferably rocky soil, full sun. Plant it slightly raised to prevent winter water accumulation, the main cause of failure.
The common mistake
Watering it regularly: an Agave survives only if it endures slight periods of drought.
The pro's trick
Wait until spring to remove dead leaves from the base; they protect against winter humidity and frost.
Care
Sparing watering
Water moderately during growth (spring-summer), then reduce drastically in autumn-winter. Let the soil dry completely between waterings: excess water is the main enemy of agaves. In a pot, ensure drainage is perfect to prevent root rot.
Full sun exposure
Place your agave in full sun for at least 6 to 8 hours daily. Maximum light guarantees intense blue-grey colouring and optimal compactness. Indoors, prefer a south or west-facing window.
Very well-draining soil
Use a cactus and succulent-specific potting mix, or prepare a homemade blend (standard potting soil + coarse sand + pumice in equal parts). Impeccable drainage is crucial for the plant's longevity.
Moderate feeding
Apply a light succulent fertilizer once or twice in summer only. Agaves are undemanding and excessive feeding risks deforming the rosette. Avoid any feeding in autumn-winter.
Little to no pruning
Remove any dry or damaged leaves at the base. No structural pruning is needed: the agave naturally forms a beautiful compact rosette. Wear gloves: the leaves are spiky.
Watch for pests
Monitor for mealybugs and spider mites, especially indoors. Excess humidity encourages rot. Ventilate regularly and avoid watering the foliage.
Did you know?
Agave ovatifolia owes its nickname 'whale's tongue' to the massive, rounded shape of its blue-grey leaves, which spread in an impressive rosette. Originating from the mountains of Chihuahua in Mexico, this species has become popular in ornamental gardening for its relative hardiness and graphic elegance, particularly in Mediterranean and modern xeriscaping designs.
Where to buy it
Plant in spring, once all risk of frost has gone. Pick a plant with healthy foliage and roots that are not exposed. Best time: from April to June.
