Title: African shadock x rubidoux trifoliate - Poncirus
Post by: Perplexed on October 14, 2018, 05:21:22 PM
Thinking about getting this variety to test it out? Anyone got information about this hardiness wise?

Might be similar to citrumelo, I would guess. Citrumelos seem to do well in zone 8. Sometimes they can survive and fruit in zone 7b.

Could also be less cold-tolerant than citrumelo since african shaddock is a pomelo. But who knows until it is tested!

Yeah apparently the seeds are $77 for I think a pint. I’ll give them a try.

Lol! That's going to be a hell of a lot of seeds. I doubt they will be as hardy as swingle & will produce large trees that are more prone to cold damage.

Yeah it’ll be a lot. I’m on border 7b-8a so I think it wont survive that long Or at all in my climate.

I would guess they have about a 50 percent chance of surviving if planted out after the plant has reached 3 feet tall.
You might cover with a cold frame to give it a chance to establish its roots the first year.

Mhm, I might try that out to establish a root system.

It will get way to large to fast to be able to protect long term.

Why do you want to grow this cultivar?  Is it for root stock seedlings?   It wonl't be very good to eat.

According to experiences from grower from Czech Republic, it survived 3 weeks of -7 °Celsius, but the taste is bad, only flowers are big and ornamental.

I really only what it for it’s look. I don’t really care about Taste because I don’t even like eating citrus in general.
