(April) I had a penta plant and a lantana plant in the garage all winter. I took
them out the first of April. The lantana already had leafed out and had a bloom.
The penta had leafed out on the end of stalks with brown leaves, it was also
growing new growth from the roots. I didn't do anything to the lantana, but cut
the penta back down to the new growth from the roots. Thinking it wasn't going
to be cold that night, I left them uncovered in the yard. Evidently it was still
too cold because the leaves were brown on the ends the next morning. Should I
just cut them back to the roots now?
A lot of people got anxious this spring and moved plants outdoors a bit early-there were temperatures from the low 30's - mid 40's many nights. Hopefully, the root system is fine and will go ahead and re-sprout new foliage. Be patient and see where growth begins again when the weather stays warm. It is helpful to prune them back some to encourage new growth. Sometimes they get awfully leggy after being protected all winter. Fertilize lightly now, and more when they get growing.
