"Any other advice would be welcome."

Next time, don't order from TyTy!! This place has a terrible reputation for both plant quality and customer service. In fact, they got so many negative reviews from the Garden Watchdog that they threatened a lawsuit unless they were removed from that review site.

But you can still research them online and the reviews continue to be uniformly bad as is their BBB rating. They also do business under a whole bunch of aliases as well.

Good luck with your trees.......I hope they are at least alive when they arrive :-)

Cancel your order if you can. They don’t have a good track record of sending the right varieties

Other than the advice to cancel your order (please follow that advice), you need to know that it takes several months to effect a change in pH with an application of lime. Six months in advance is a good rule of thumb.
