What’s wrong with my Knockout Rose bush??

by Amanda Broach Stanaker

Answered

Hi, I’m a very new at taking care of ANY kind of plant. We recently added beds around our pool in the backyard and I’m trying very hard to keep everything alive in this Texas heat (Houston). Can anyone tell me what is wrong with this knock out rose bush and how to treat it? Could it be overwatering or that the soil is staying too wet? It is located in a spot close to where the water drains. Any advice would be appreciated! TIA.

  As you're new to gardening, note that some mulches have been treated with chemicals which can damage some plants.
  Never place mulch up against the center stem growth. Leave at least an inch on all sides.
  Because you're in TX, you may want to consider installing a drip hose system, as roses dislike overhead watering.
  Bayer makes a granular rose food that's applied around the drip line, every 6 weeks.
  Roses do well interplanted with Artemesia.
  Pick up and dispose of all leaf litter.
  Epsom salts, used lightly and dug into the top two inches of soil can intensify your rose's color.

Knock out Roses are really easy to keep up. Here in Texas were use to watering but not their leaves they do not like that. I trim ours back a few times a year because they get too tall. Basically ignore them and they do good fertilize one x a year.
