Alright folks, let’s talk about my Dipladenia, or Mandevilla, pruning adventure! This thing was getting outta control, vines everywhere, so I figured it was time for a haircut.
First things first, I grabbed my trusty pruning shears. Made sure they were nice and sharp – ain’t nothin’ worse than mangling stems with dull blades. Gave ’em a quick wipe down with some rubbing alcohol too, just to be on the safe side and avoid spreading any potential diseases, you know?

Then I just kinda…stared at the plant for a bit. Needed to figure out what I wanted to achieve. My main goal was to tidy it up, get rid of some of the crazy-long vines, and encourage more bushiness. It was getting leggy, if you know what I mean.
So, I started snipping! I focused on removing any dead or damaged growth first. Yellowing leaves? Gone. Broken stems? Adios! That alone made a HUGE difference. The plant already looked healthier.
Next up, I tackled those super-long vines. I cut them back pretty hard, like maybe a third or even half their length. I made my cuts just above a node, which is where a leaf or another stem grows out. That’s supposed to encourage new growth from that point. We’ll see if it works!
There were a couple of vines that were just growing in the wrong direction, like straight into other vines. I chopped those off completely. No room for drama!
I also thinned out the center of the plant a little bit. It was getting pretty dense, and I wanted to make sure that light and air could reach all parts of the plant. That helps prevent diseases and encourages better blooming.
Key things I learned:
- Don’t be afraid to prune! These plants are pretty resilient.
- Make sure your shears are sharp. Seriously.
- Cut at an angle, just above a node.
- Step back every once in a while to see how it’s looking.
After I was done pruning, I gave the plant a good watering and added a little bit of fertilizer. Figured it deserved a treat after all that work.

Now, all that’s left to do is wait and see how it responds! I’m hoping for a bushier, more compact plant with tons of blooms. Fingers crossed! I’ll try to update you guys in a few weeks with the results.
