https://xuatkhautraicay.com/shop/xoai-cat-chu-xanh-cao-lanh/Farmers started bag up individual fruit at 45 days old. Depending on the color of the bags used, black and yellow bag gives pale yellow Cat Chu, and white bag give Green Cat Chu, even when ripe, but the fresh with deep orange color and taste are the same for both yellow and green varieties. To develop the best taste, farmers wrapped each fruit in newspaper and stored in cool place for 3 days before sale. Majority production is located at farm land near the river where the land is covered with rich silt from annual flooding.
I got some Cat Chu budwoods from Alex and grafted them last weekend. I hope my fruits will be just as good as those fruits from Vietnam that had been grown hundreds of year ago.
