"We had a good flowering, and then all of that rain [in December] helped keep the buds on, probably because of all of that nitrogen in the air," he said.

"We've used a lot of fertiliser this year and put a lot of work [into the orchard] early in September, with all of the mulching and nutrition, so it's been good."

Mr Karlsson admits the huge yields from his farm in December flooded the national market, but the fruit being picked now is steady and of excellent quality.

"This bit of rain and bit of sunshine we're having now is nice. I don't want that monsoon like we had in December. We had around 700 millimetres and that was too much for the fruit," he said.

"We had a record December pick of around 6,500 trays, which is big.

"We're starting another pick today which will be a smaller one, but we had a massive flowering a few nights ago, so hopefully we'll crack last year's farm record [of more than 16,000 trays and 3,000 bulk boxes].

The dragon fruit season in the Northern Territory will wrap up in April.
