Last week I went on vacation and some of my plants got too dry without me there to take care of them. I know that this has happened to all of us.
Almost always the damage can be repaired and with very little effort.
First, get out the pruners or your favorite scissors and trim off everything that has been damaged or dried out. Next add water. That’s it! Nothing more difficult than that.
I will caution you not to use fertilizers until you see noticeable improvement and do not repot as a lot...
