I have four purple salvias, which are beautiful. They bloom nice but they get large and lay over. They are dense and they are four years old. I need to know how to get them to remain upright for the season.
Salvia Too Large and Falls Over
Certified GKH Gardening Expert
If your plants are getting too large to support the weight of the flowers, they will normally flop over like this. While you can prune the plants back to encourage bushier growth, I would simply provide additional support for the plants using plant stakes to help support them. These are available at most nurseries.
