Beginner Begonia,
I'm from the North and I put begonia's in pots (because they don't over winter up here)
But I'd say if you weeded around your begonia's and now they are yellowing.........
I'd have to ask some questions????
When you pulled out the
weeds were the roots intertwined with the begonia's roots?.......
Did you firmly place the dirt back around your begonia's roots?????
Did you give it some Miracle Grow?
(10-60-10)????
That will help with the root shock and reroot growth and then flowering.......
What type of day??
And time of day???
Now you live in Fla., a hot place.......
On days when it's really hot and the roots are disturbed and maybe not refirmed up and in shock your leaves will show the effects...
Try this, let us know how it turns out..
Weezie
