How long does it usually take for a pineapple to be ready to pick after it forms? I have 2 and one is about 4-5 months old and only about 6-7 inches tall, not counting the crown(very firm still) and 4-5 inches in diameter. The other is also 4-5 months old but only 4-5 inches tall and 4-5 inches in diameter. This one looks like a pineapple softball. lol
