I recently saw some trees grafted on Sun Chu Sha Kat for the first time. Does anyone have any experience with the plant, either as a rootstock or with the fruit?

I've considered it as a rootstock for my inground trees due to it's ability to tolerate and utilize magnesium when planted in calcareous soils but have been waiting on some solid information about it's effect on fruit quality. I found some information suggesting that fruit quality for trees budded on CSC is sub par and that fruit size is also below average. I'm also unsure of it's cold hardiness. A commercial citrus nursery that I visited in Central Florida recently was budding sweet oranges on it for a client that wanted to see how it performed.

Thanks. If you do try it out, let me know how it does with regard to the cold.

Sun Chu Sha mandarin seems to have a lot of strikes against it. It is poor in wet soils, susceptible to both burrowing nematodes and citrus nematodes, plus being susceptible to foot rot, and root rot. The root stock generally produces low yields, and small size fruit. It is a large tree when grown as a tree. - Milllet
