How to prune Beach Sunflower?

When you want to keep your Beach Sunflower looking its best, a little pruning in late spring or early summer is just the thing. Using a sharp knife or garden shears, gently trim away the damaged or dead stems and any stems that don't look right. Next, cut the plant back to the exact shape you have in mind. Make sure there's plenty of room for air to circulate, and don't forget to remove those spent blooms regularly. That way, you can prevent your plant from going crazy and sending out bunches of flowers all on its own.

I have beach sunflowers, which I adore, and I always prune them in late spring.
First, I use garden shears or a sharp knife to cut off damaged leaves or flowers that aren't looking their best.
Second, I make cuts at a 45-degree angle near a leaf node to encourage new growth.

Spring is the perfect time to give your plant a little boost and help it grow in the shape you want! Here's what you can do:
First, pick a dead stem or one that's a bit damaged.
Next, snip the part that might start to grow leggy.
After you've cut it, care for it like you would any other plant. Ensure it has enough water, especially during dry periods, and add fertilizer during the growing season to help it thrive!

I haven't tried it yet because I don't have this plant, but I'm looking forward to trying it soon!

I totally get it, sometimes a clean pair of scissors is all you need!
