Description: Pollination Fruits are formed without pollination.
Cultivation and Propagation: Ananas is an valuable ornamental bromeliads due to the beauty of its foliage, inflorescences and fruits along with the facility of cultivation. Some ornamental varieties, including variegated cultivars are very valuable landscape plants that require very little care and create exotic tropical look.
Growing substrate: It requires a well-drained, aerated, porous and moisture-retentive substratum which is rich of organic substance (e.g. 2 parts peat moss to 1 part loam to 1 part sand or perlite). Use only acidic soil. Root rot can be a problem if the soil is too moist.
Exposition: It prefers prefers a sunny site but tolerates partial shade.
Watering: It enjoys constant moderate moisture from rain or sprinkler, but allow the plant to dry in-between waterings. However it is quite drought-tolerant and may be also planted in dry succulent gardens. In dry and hot climate, humidity can be increased with nebulisations utilizing water at room temperature and not calcareous. In summer, some distilled water can be left in the central cavity formed by the rosette of leaves, whilst in winter it is better to leave it dry, thus avoiding possible rottenness. Requires complete and perfect drainage.
Fertilizing: Fertilize every 4-week during the growing season with a balanced fertilizer diluted to ½ the strength recommended on the label. Apply mild solutions (one-quartet strength) of foliar fertilizer at 3-month intervals to both garden and container plants.
Hardiness: It is cultivated in open air in the tropical and humid subtropical climate countries, with temperatures which it is good to keep over the 14°C, best 20-24°C , but can withstand light frost for short periods if very dry (hardy down to -2 to -4º C, even if with damage to the foliage) in these situations it will better resist if sheltered by the winter rains, seen that the humidity and low temperatures render it more sensitive to rottenness. USDA Zone 9b to 11
Pest & diseases: It is susceptible to scale, trips and mosquitos that will sometimes breed in the pools of water that are trapped between the leaves. Mealybugs infestations are also a frequent problem.
Pruning: Remove old leaves from plant base and dead ﬂower spikes only. Remove older plant crown when it begins to fade.
Use: Specimen plant; mass planting; container plant; tropical foliage and colourful ﬂowers.
Propagation: Remove and replant stout offshoots from the base of the parent plant. May also be grown from seed: remove seeds from inﬂorescence and lay them uncovered on a bed of crushed tree fern ﬁber; keep constantly but moderately moist. The seeds should be dipped in diluted sulphuric acid to increase germination rate. Starting from the seed, at least 5-6 years are needed for the blossoming, whilst at least 3 years are needed by division.
Warning: Plant has spines or sharp edges that deter some gardeners; use extreme caution when handling.
