Dragon fruit splitting: Why & how to prevent it

Dragon Fruit Plants 13 May 2020

There are several ideas for the causes of dragon fruit cracking. It may be due to over-watering when the fruits are nearly ripe. Sometimes, growers leave the fruits on the trees for quite a while to wait for better resale prices. This may also cause cracking.

Some growers in areas like California experience this thing while others in Florida usually don't. Along these lines, growers believe the soil may be too dry or it's the uneven heat & humidity causing the fruits to split.

For example, after a long dry & sunny period it suddenly rains, the fruits will tend to crack. This is a somewhat mechanical reaction. Sometimes it might be the variety & their skin characteristics. Sometimes it may also be the lack of calcium (the building material of cell wall) that contributes to the problem.

If the fruits ripe during the rainy season, the chance of fruit splitting is higher. The bite of a fruit fly might create an opening (with little maggots) for the fruits to crack out.

This cracking opens the doors to bacteria & fungi which chew up all the good fruits. To minimize dragon fruit cracking, try:

  • Not to over-water as the fruits are developing for about 10-15 days
  • Misting water around the lower stem
  • Using a calcium spray with 1% boron
  • Harvest the ripe fruits when it seems like it's about to rain soon

As the fruits are becoming ripe, we water less but more often. Also, feed them less so the fruits can grow without any blockages. Specifically, when it's about to rain & we just leave the ripe fruits on the trees, it's almost guaranteed that the fruits will crack on the same day or the next day. So pick the fruits before they split.

We found a YouTube video showing the split dragon fruit, but we forgot what it's called. Let us experiment some more. If you have any experience with this, please share. That'd be incredibly helpful.
