Stay the course. its possible the plants are just recovering and setting up to grow around the cuts. Look for signs of swelling at the leaf nodes nearest to the cuts. IMO 8 inch pots seem to be under size but maybe hold off on that for later.

Thanks for the info! The 8" pots is what they were in.... I transplanted them into 14" containers. I know that may seem a bit extreme, but once they leaf out they turn into sails.... The slightest bit of wind seems to blow them right over.

14 inch doesn't sound extreme to me. I have plants 3-4 ft tall in 22 inch whiskey barrel containers. The leaves will rip off before they blow over. The taller ones will blow over at about 40-50mph.

Sounds like the plant just had to deal with the tip damage. Good to read.

If you want to get to the bottom of why the tips blackened in the first place and how to avoid that in the future, we'd have to know more about their winter conditions...temperature, humidity, light, duration of time 'dormant', watering, when you brought them in in the fall, etc.

Typically when tips are damaged this way, they abort and it can take a lot longer for them to regenerate new growing tips. Sometimes even into July or August. So your growing season this year is severely shortened. Best to keep your plants from stressing to the point where they get black tip in the first place.
