In Austin now in March, you should get them putting out green growth by about 10 days, and hope temperatures don't drop below freezing much at night. I'm assuming you mean bare-root dormant plants that were properly stored, planted and are now well irrigated. But your results may vary depending on their conditioning before you got them, storage at the store and whether you get them in the rig quickly enough.

They will eventually catch up to regular green plugs if all goes well, but unfortunately the likelihood of disease is very high since they are not coming from a certified pathogen-free nursery, so I hope luck is on your side.
