Deadheading vs Cutting? And Then There's Pinching? What To Do When?

I received some questions from one of our fellow gardeners regarding deadheading, cutting and pinching with regards to her Zinnias and Marigolds. I thought that there were probably other gardeners in our community that have pondered these same questions with regards to these garden terms.

I wanted to answer those questions here so anyone that is wondering when to do what would benefit from the discussion.

𝐎𝐮𝐫 𝐦𝐞𝐦𝐛𝐞𝐫𝐬 𝐪𝐮𝐞𝐬𝐭𝐢𝐨𝐧: "What I wanted to ask is for my Zinnias and Marigolds, how to I cut them so they will grow more flowers. But also I want to have them in vases in my house. I keep hearing about deadheading and cutting. Can I do one or do I have to do both? I keep hearing about pinching Zinnias too. When would I do that?"

𝐌𝐲 𝐫𝐞𝐬𝐩𝐨𝐧𝐬𝐞:

Hi! Great questions and the good news is that Zinnias and Marigolds are both "cut-and-come-again" flowers, which means the more you harvest them, the more flowers they usually produce.

𝐃𝐞𝐚𝐝𝐡𝐞𝐚𝐝𝐢𝐧𝐠 means removing old blooms 𝐚𝐟𝐭𝐞𝐫 they start to fade or go to seed. This tells the plant, "Don't make seeds yet, make more flowers instead!"

𝐂𝐮𝐭𝐭𝐢𝐧𝐠 𝐟𝐨𝐫 𝐛𝐨𝐮𝐪𝐮𝐞𝐭𝐬 does the same thing, as long as you cut the stem back to a set of leaves or a branching point. Every time you bring flowers inside for a vase, you're essentially deadheading and harvesting at the same time.

So no, you don't have to do both. If you're regularly cutting flowers for bouquets, you're already encouraging the plant to produce more blooms.

When harvesting Zinnias, don't just snip the flower head. Follow the stem down and cut just above a set of leaves or where another side stem is growing. New stems and blooms will emerge from those leaf nodes.

The same idea applies to Marigolds. Remove spent flowers or cut stems for bouquets back to a leaf set. This keeps the plant looking tidy and encourages continuous blooming.

Pinching is something you do when the plant is still young. When a Zinnia seedling is about 8–12 inches tall and has several sets of true leaves, you can pinch or snip off the top few inches of growth.

It feels scary the first time, but it encourages the plant to branch out, giving you:

More stems
More flowers
Stronger plants that are less likely to flop over

If your Zinnias are already flowering, it's probably too late to pinch them, but that's okay! You can simply start harvesting blooms regularly and they'll continue producing.

🌱 𝐄𝐚𝐬𝐲 𝐫𝐮𝐥𝐞 𝐭𝐨 𝐫𝐞𝐦𝐞𝐦𝐛𝐞𝐫:

𝐘𝐨𝐮𝐧𝐠 Z𝐢𝐧𝐧𝐢𝐚𝐬 = 𝐩𝐢𝐧𝐜𝐡 𝐨𝐧𝐜𝐞.

You'll end up with more flowers outside and fresh bouquets inside!

𝐏𝐒: Do the "𝐰𝐢𝐠𝐠𝐥𝐞 𝐭𝐞𝐬𝐭" before cutting Zinnias. Grab the stem about 8 inches below the flower and gently wiggle it. If the stem feels stiff and doesn't flop, it's ready to cut for a vase. If it bends easily, leave it on the plant another day or two. That little trick dramatically improves vase life. 🌸🌿
