What soil type works best for pineapples?

Prof. Martin Thorne, Ph.D.Pineapples require specific soil conditions that many gardeners neglect. My early mistakes showed me fast-draining mixes are essential, because the first three I had died because of clay-based soils, and finally switched to a better, more gritty cactus mix. Good soil prevents root rot, which mimics their natural habitat on volcanic soils.
Base Mix
- 3:1 ratio of cactus soil to perlite
- Add coarse sand for heavy rainfall regions
- Top dress with 1" gravel to prevent compaction
pH & Drainage
- Test soil annually, target 5.5-6.5 pH
- Use sulfur to lower pH if above 7.0
- Avoid water-retentive additives like peat moss
Mixing the soil is akin to baking; propose a recipe, and the ingredients must be exact. I utilize a 5-gallon bucket to measure 3 parts of cactus potting soil to 1 part of perlite. For acidic pH, use pine bark fines in the mixture. My Florida plants love this soil mixture, even through heavy rain, and the gravel base prevents soggy roots.
Do not buy bagged potting mixes that state they have "moisture control." These water-retaining crystals will drown your pineapple roots. I lost two pineapple plants because of that before realizing the problem. Rather, mix your substrate, which is 60% less than popularity premixed tropical soil.
Before planting, test drainage! Pour 1 quart of water into your mix and it should drain completely in less than 90 seconds. My homemade mix drains in 45 seconds, and standard potting soil takes 4 minutes. Adjust the ratios and mix until you find the right balance.
