Pineapple Collection 2015
|The pineapple (Ananas comosus) belongs to the bromeliaceae
family. It is a terrestrial (soil growing) bromeliad, and it is native to the
tropical and warm subtropical regions of Brazil and Paraguay.|
The pineapple is a slow-growing, herbaceous, perennial. It has a short stem which is covered by long, narrow, sword-shaped leaves arranged in a rosette pattern. Some varieties have spines along the leaf edges. The plant grows about 3 feet (100cm) in height and spreads up to 6 feet (183cm). A large plant can have as many as 80 leaves. At the time of flowering, a flower stalk appears from the plant's center bearing a reddish cone-shaped leaf cluster. A purple or red flower appears between each leaf. Flowering starts from the bottom and progresses towards the top. No special pollination is required. The fruit is seedless; however, if two different varieties are grown near each other, the cross pollination produces tiny black seeds. The fruit slowly develops and ripens in 4 to 5 months after flowering.
|Obtain a pineapple fruit that has an unbruised, dark green leafy crown. Hold the fruit and grab the crown at the base and remove it by twisting it off. Pull a few of the bottom leaves off until 3/4" to 1" ( 1.9 to 2.5cm) of the stem is exposed. Along the exposed stem, roots will form. Set the crown aside for a few days in a warm, airy place out of direct sunlight until a callous forms. After that, the crown is ready to be planted.|
|Plant crown in a 10" (25cm) or 12" (30cm) pot. Any soil mix that is well-drained, moisture retentive, and acidic with a high organic matter content can be used. Gently firm the soil up around the crown's base to support it. Move to a warm, bright area with filtered sunlight. Keep the soil moist, not wet. About 4 to 8 weeks later, the leaves will begin to grow out. Gradually introduce to full sun.|
|Pineapple plants have a high demand for nitrogen and potassium.
They grow very well when needed elements are supplied at a slow, constant rate.
Apply a slow release, non-burning dry fertilizer to the soil every 3 months
or water with a very weak fertilizer solution at every watering.
If you're into organic gardening, there are several organic fertilizers you can use. Bat guano, feather meal, and blood meal are rich sources of nitrogen. Rock phosphate, steamed bone meal, and bat guano supply phosphorus. Sul-Po-Mag supplies potassium, magnesium, and sulphur. Rock powders such as Azomite or Green Glacier supply all necessary trace minerals to feed both plant and soil. Seaweed extract and Kelp meal are excellent growth enhancers. Worm castings or aged compost can be added to improve soil structure and plant growth.
|There seems to be a common misconception that all bromeliads like water
poured in the center of the plant. This is NOT true! The "tank" bromeliads,
like Aechema fasciata, need water held in the center. When water remains in the
center of a pineapple plant, it can lead to rot. Water the soil thoroughly
until it drains into the bottom saucer. Don't let water stand in saucer. Allow
the soil to dry slightly between waterings.
Bromeliads like the pH of the water to be slightly acidic. Check with your local water department to find out about the pH. If your water is hard (alkaline), add 2 tbsp of vinegar per gallon of water.
|Pineapples enjoy evenly warm temperatures all year long. A warm growing environment with a daily average temperature
between 75°F (24°C) and 80°F (26°C) is optimal for excellent growth and fruiting. Move plants outdoors when both
days and nights are consistently warm. Plants can tolerate occasional lows in
the 50's (10°C - 15°C), but prefer 60's (16°C - 20°C). Highs
should be 75°F to 90°F (24°C to 32°C). When temperatures reach
90°F (32°C) or more, plants should be placed in filtered sunlight to
Humidity can be a problem indoors during the heating season. The humidity level should be maintained at 50% to 55%. A room humidifier placed on a timer provides an effective way of maintaining humidity levels.
|Plants are grown under a six bulb T5 high output fluorescent lighting fixture.|
|Having adequate light indoors is absolutely essential for good growth
and fruiting. Pineapple plants require at least 12 hours of bright light a day. Artificial lighting can be used as the only light source
or a supplementation to natural daylight.
High intensity discharge, T5 high output, T5 very high output, and LED lighting systems are excellent choices for growing pineapples. Check out my online garden suppliers page.
When it is time for your pineapple plant to go outdoors for the summer or indoors for the winter, it needs to be acclimated to its new environment. The plant should gradually be introduced to more shade over a period 3 weeks before going indoors. When going outdoors, place plant under a shade cloth or in an area that only receives the weak morning or evening sun. Over a period of 3 weeks, gradually introduce to more sunlight.
|When leaves start getting out of bounds, prune them back with a sharp pair of scissors. Cut the leaf straight across then shape the cut like an arrow. This will make the pruned leaf look more natural. To remove yellowing and dead leaves, split them straight down the middle and pull apart from the stem.|
|Indoor pineapple plants are not usually bothered by many pests or diseases.
However, mealy bugs and scale insects do attack them. These pests can be
effectively controlled by using a 1% to 2% light horticultural oil spray or neem oil.
Fungus gnats can be a real nuisance indoors. They love damp areas and moist soil rich in organic matter. The adults fly around and lay eggs in the soil. Then a few days later, the larvae emerge damaging young roots. There are two effective controls: biological, Gnatrol WDG, and predatory mites, Hypoaspis, that feed on gnat larvae.
Diseases that appear on indoor pineapple plants are sometimes due to incorrect cultural practices. Overwatering can cause root rot. Heart rot can happen if water is poured and allowed to stay in the plant's center for long periods of time. Leaves staying wet from misting without adequate air circulation can encourage leaf spot disease if spores are present.
Anthracnose is a fungal disease which attacks the leaves. When conditions are favorable ( cool and wet ), it first appears as a brown patch or streak on the underside of the leaf. Then, the leaf's surface becomes discolored with pale yellow to brown spots. An effective preventative and control for this disease is neem oil.
|Leaf edges curl under||Low humidity, underwatering, acclimation||Buy humidifier to increase relative indoor humidity, water when the top 2" (5cm) of soil is moderately dry, gradually introduce plant to new environment|
|Brown spots on leaves||Fertilizer burn, salts in water||Fertilizer should be slow release, use distilled water or clean rainwater|
|Small brown or black lesions on leaves||Fungal infection, Anthracnose||Cool, wet conditions favor growth, avoid wetting leaves, temps above 80°F retard fungal growth, use neem oil or biofungicide|
|No plant growth||Cool temps, underwatering, overwatering, low light or not enough light||A mean temp between 75°F (24°C) and 80°F (26°C) is optimal for excellent growth, check rootball, water when the top 2" (5cm) of soil is moderately dry, move to brighter area|
|Brown leaf tips||Low humidity, fertilizer burn, underwatering||Buy humidifier to increase humidity, fertilizer should be slow release to avoid burning, water when the top 2" (5cm) of soil is moderately dry|
|Fruit not large||Plant was forced to bloom when young, inadequate leaf surface||Force bloom when the plant has a minimum of 35 mature leaves on it. Plant should measure 2 to 4 feet across depending on variety. This insures a decent fruit size.|
|Yellowish, white, or red spots on leaves||Mealy bugs or scale insects||Look for pests in the leaf axils and treat with a light oil spray or neem oil.|
|Lower leaves yellow and dry up||Underwatering, rootbound, acclimation (high light to low light), dimming artificial light||Water when the top 2" (5cm) of soil is moderately dry, check rootball and repot if necessary, gradually introduce plant to a new environment, change light bulb|
|Yellow-green leaves||Nitrogen deficiency, root rot, improper acclimation- low light to high light||Use a 2-1-2 ratio fertilizer preferable organic, check rootball and let it moderately dry out between waterings, gradually introduce plant to a new environment|
|Flowering occurs naturally in mature plants when the days are
short and cool. However, pineapple plants seldom flower on their
own under indoor cultivation. A technique called
"forcing" has to be used to initiate the flowering cycle.
Forcing can be achieved by using plant growth regulators, calcium carbide, acetylene gas, or ethylene gas.
Chemical growth regulators such as Ethephon, Florel, and Omaflora are used commercially and are not available for retail sale.
Calcium carbide needs to be handled with caution. A small lump is added to the plant's center, then water is added. A violent reaction takes place releasing acetylene gas (flammable) into the air and water.
Ethylene gas is produced naturally from apples, pears, peaches, and other fruits. To maximize ethylene exposure, place ripening fruit at base of plant for one week. Approximately 45 days later, a flower cluster should appear in the plant's center.
Forcing is most effective when done during cool to moderate temperatures (60's to low 70's/16°C-23°C) and at night.

|For maximum sweetness and flavor, it is best to pick the fruit when it is fully ripe. Once the fruit is harvested, it will not improve in quality! Depending upon the variety grown, a ripe pineapple can either be yellow-orange, orange-red, yellow, red, green, or purple. To harvest fruit, use a sharp knife or pruning shears and cut stalk one inch below the fruit.|

|Pineapple plants, like all bromeliads, slowly fade away after
flowering. Before this happens, the plants will produce one or more types of
leafy offshoots: crowns, slips, suckers, and ratoons. Crowns are shoots which
grow on the tops of the pineapple fruits. Slips are shoots which grow on the
flowering stalk. Suckers are shoots which originate from the leaf axil on the
stem above ground, and ratoons are suckers that grow from the stem below soil level.
Crowns should be the first type of propagating material used if you want to establish new plants quickly. Suckers and ratoons are generally larger, stronger, and bear fruits sooner. Remove suckers with a sharp, serrated knife when they're at least half the size of the mother plant. Plant suckers the same way as crowns. Slips can be numerous on some pineapple varieties, like as Sugarloaf. If you want your fruit to be as large as possible remove them before they fully develop. If you want more plants, allow them to grow at least 4 to 6 inches (10 cm to 15 cm ) before removal.
|There are hundreds of pineapple varieties but only a few dozen are good enough to be grown on a commercial scale.
