Cultivation in Ohio

Primary Uses:

 Fresh fruit

 Planting:

 Crowns, slips, suckers and ratoons are used for vegetative multiplication of the pineapple rather than seeds.  Planting depth ranges from 2 to 4 inches depending on which type you are using.

 Seeding Rate:

 Plants are set in double rows with 12 inches between plants and staggered settings on the opposite row.  Typically the rows are 2 feet apart with a 3-5 foot alley between the row pairs.  Total plants per acre range from 14,500 to 18,000 plants.

Fertility:

 Ideal pH should be within a range of 4.5 to 6.5.  Nitrogen is essential to the increase of fruit size and total yield. Some fertilizer trials have shown that a total of up to 420 lbs N/acre (471.7 kg/ha) in 4 equal applications during the first year is beneficial, whereas no advantage is apparent from added potassium and phosphorus.

Insects:

 Nematodes, Mealybugs, pineapple mite, sap beetle, cutworms.

Diseases:

 Top rot, root rot, base rot, yellow spot virus, crookneck

Harvest:

 Harvest of seedlings may start 16-30 months after transplanting. The same fields may be maintained for 2-4 harvests.

Comments:

 Green pineapples are poisonous.    TCS
