Q.Pineapple Plants Not Growing

Zone Delray Beach, Florida | DonR added on July 14, 2021 | Answered

I have 4 pineapple plants, 2 in pots and 2 in the ground. They were growing fine. Then I read a couple of articles that said used coffee grounds were good for the plants so I put some around them. After about 2 weeks I noticed that they stopped growing. I checked this out on line and found some articles that said the acid in coffee grounds could do this. Is there a remedy for this? Thanks

I would say to check soil fertility, and moisture levels. It is much more likely that the soil is too moist. This will stop growth of Pineapples. They need the soil to alternate between moist and dry, preferring things to be on the dry side.

Coffee grounds do not contain enough acid or nutrients to make a difference for one use. In fact, you would have to use it un-brewed coffee grounds all season to notice any difference.

I would suggest getting a meter to measure soil moisture. Don't water until it is completely dry down to about 3 or 4 inches. This article will help:


Feed them well. They use nutrients quite quickly. They can take up nutrients through their leaves faster than they can through their roots, so use that fact to your advantage. This article will help you to grow pineapples successfully:

I haven’t watered the plants in a long time but I live in south Florida. It is the rainy season so unfortunately I have no control over how much rain there is so they are getting a decent amount of water.
