Dragon fruit cracking or splitting up may be because of over-watering when the fruits are nearly ripe & some other mechanical factors. Sometimes, growers leave the fruits on the trees for quite a while (to wait for the prices to go up) which can also cause cracking.

A crack on a dragon fruit can look a bit like this:


Some growers in areas like California experience this thing while others in Florida usually don't. While finding a cause for this problem, they 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 and it suddenly rains, the fruits will tend to crack. This is a somewhat mechanical reaction. Sometimes it might be the variety & their skin characteristics. Other times it may also be the lack of calcium (the building material of cell wall) that contributes to the problem. It can be thought of like a cracking bone (although this is not the best analogy).

This red one is probably too plump that it cracks open:

If the fruits ripen 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 flesh inside. To minimize dragon fruit cracking, try:

  • Not to over-water as the fruits are developing for about 10-15 days
  • Misting water around the base
  • 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 ripening, 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 they will crack on the same day or the next day. So pick them before they split or before it rains.

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 it with us. That'd be incredibly helpful. Thanks for visiting & see you again here at the garden next time for more dragon fruit stuff.
