ByRimon Chowdhury Updated on

Have you ever walked out to your garden, admiring your thriving garlic patch, only to spot a strange, curly stalk shooting up from the center of a plant? Your first thought might be, “Oh no, what’s happening?!”

I get it completely. Seeing your garlic doing something unexpected can be a little alarming. But let me reassure you, my friend: this isn’t a sign of failure. In fact, it’s a fantastic opportunity and a normal part of the growing cycle for many garlic varieties.

I promise to walk you through exactly what this “flower” is, what it means for your final harvest, and how you can turn it into a delicious bonus crop. This is your ultimate garlic plants flowering care guide.

In this post, we’ll cover everything you need to know about garlic plants flowering. We’ll dive into what garlic scapes are, the crucial decision of whether to cut them (and why you almost always should), how to harvest and use them, and some sustainable best practices for a happy, healthy garlic patch from start to finish.

What Are Garlic Scapes? Understanding the “Flower” on Your Garlic Plant

First things first, let’s clear up a common misconception. That curly stalk emerging from your garlic isn’t technically a flower in the way we think of a daisy or a rose. It’s called a scape, and it’s the flowering stalk of a specific type of garlic.

The scape’s biological purpose is to produce a cluster of tiny, pea-sized garlic clones called “bulbils” at its tip, which can then fall to the ground and grow into new plants. It’s the plant’s way of reproducing itself without relying on the underground bulb.

Think of it as the plant trying to create both a bulb underground and a family of tiny new plants above ground. It’s a clever survival strategy, but it requires a lot of energy.

Hardneck vs. Softneck: The Scape Divide

You’ll only see these scapes on hardneck garlic varieties (like Porcelain, Rocambole, and Purple Stripe). These are the varieties that thrive in colder climates and are known for their complex, robust flavors and—you guessed it—the hard, woody central stalk that gives them their name.

Softneck garlic (like Artichoke and Silverskin), the kind you most often find in grocery stores and that’s ideal for braiding, typically does not produce a scape. If you see a softneck variety sending up a flower stalk, it’s usually a sign of stress from inconsistent watering or temperature fluctuations.

The Big Debate: To Cut or Not to Cut Your Garlic Scapes?

This is the central question for every gardener who discovers their garlic plants flowering. The short answer is almost always: yes, you should cut the scape.

But as with all things in the garden, understanding the “why” is key. This isn’t just a random chore; it’s a strategic move that directly impacts the quality of your harvest. Here are some detailed garlic plants flowering tips to help you decide.

The #1 Reason to Cut: Boosting Your Garlic Bulb Size

Remember how we said producing that scape and its bulbils takes a lot of energy? When you let the scape grow, the plant diverts its resources—sugars, nutrients, and water—away from the underground bulb and sends them upward to the flower head.

By snipping off the scape, you perform a simple act of redirection. The plant, no longer needing to fuel its aerial reproduction, sends all that precious energy back down into the bulb. The result? Studies and gardener experience have shown that this can increase your final bulb size by 25-30% or more. That’s a huge difference!

When to Let It Grow: Propagating with Bulbils

There is one main reason you might choose to leave a scape or two on your plants: to harvest the bulbils for replanting. This is a fun, sustainable way to increase your garlic stock over time.

Just know that growing garlic from bulbils is a long-term project. The first year, they’ll grow into small, non-cloved “rounds.” You’ll need to replant these rounds in the fall, and in the second or even third year, they will finally mature into full-sized, cloved heads of garlic. It’s a patient gardener’s game!

A Complete Garlic Plants Flowering Guide: How and When to Harvest Scapes

Okay, so you’re convinced. It’s time to cut the scapes. But when is the perfect time, and what’s the best way to do it? Getting the timing right is easy once you know what to look for. This is the core of our garlic plants flowering guide.

Identifying the Perfect Harvest Window

You’ll want to watch your hardneck garlic closely in late spring or early summer. The scape will emerge from the center of the top leaves as a straight green shoot.

Let it grow a bit. The ideal time to harvest is when the scape has formed one or two full curls or loops. At this stage, the scape is tender, packed with flavor, and hasn’t yet drawn too much energy from the developing bulb.

If you wait too long, the scape will straighten out and become tough and woody, losing its delicate flavor. Don’t worry—even if you miss the perfect window, cutting a tougher scape is still better for your bulb’s growth than leaving it on.

The Best Technique for Cutting Scapes

This is the easy part! You don’t need any special tools, though a clean, sharp pair of scissors or pruning snips makes the job quick.

  1. Locate the Base: Follow the curly scape down to where it emerges from the topmost leaves of the garlic plant.
  2. Make the Cut: Snip the scape as close to the leaves as you can without damaging them. A clean cut is best.
  3. Gather Your Harvest: Collect your scapes in a basket. You’re now holding a delicious, gourmet ingredient!

That’s it! You’ve successfully managed your flowering garlic and secured a bonus harvest. It’s one of the most rewarding two-for-one deals in the vegetable garden.

Beyond the Bulb: The Amazing Benefits of Garlic Plants Flowering

The biggest benefit of garlic plants flowering is, without a doubt, the scapes themselves! They are a true culinary delight with a flavor that’s like a milder, fresher, greener version of garlic, often with a hint of onion or chive.

Don’t let this bonus harvest go to waste. Here are a few simple and delicious ways to use your garlic scapes:

  • Make Garlic Scape Pesto: This is a classic! Simply replace the basil in your favorite pesto recipe with chopped garlic scapes. It’s incredible on pasta, sandwiches, or as a dip.
  • Grill or Roast Them: Toss whole scapes with a little olive oil, salt, and pepper. Grill or roast them until they’re tender and slightly charred. They make a fantastic side dish.
  • Chop and Sauté: Use chopped scapes just as you would use garlic or green onions in stir-fries, omelets, soups, or sautés.
  • Pickle Them: Pickled garlic scapes are a zesty, crunchy treat that can be enjoyed all year round. They’re a wonderful addition to a charcuterie board or a bloody mary.

Troubleshooting: Common Problems with Garlic Plants Flowering

Even with the best care, you might run into a few issues. Here’s how to handle some common problems with garlic plants flowering.

“Why Didn’t My Hardneck Garlic Produce Scapes?”

If your hardneck garlic isn’t flowering, it could be due to a few factors. Young plants grown from small cloves may not have enough energy to produce a scape in their first year. Additionally, insufficient chilling hours over the winter (a requirement for hardneck garlic) or poor soil fertility can prevent scape formation.

“My Softneck Garlic is Flowering! What’s Wrong?”

As mentioned, softneck garlic doesn’t normally produce a scape. If you see one, it’s called “bolting,” and it’s a sign of plant stress. This is often caused by a sudden heatwave, inconsistent watering, or a nutrient deficiency. Cut the stalk off immediately to encourage the plant to refocus on its bulb.

“I Cut My Scapes, But My Bulbs Were Still Small.”

Cutting scapes is a huge factor in bulb size, but it’s not the only one. Small bulbs can also result from planting too late, nutrient-poor soil, weed competition, or not enough water during the critical bulb-swelling phase (which happens in the last month before harvest).

Sustainable and Eco-Friendly Garlic Plants Flowering Best Practices

Growing garlic can be a wonderfully sustainable practice. Embracing eco-friendly garlic plants flowering techniques ensures you’re giving back to your garden’s ecosystem.

One of the core tenets of sustainable garlic plants flowering is using the whole plant. Harvesting and eating the scapes is a perfect example of this “waste not, want not” philosophy. You’re getting two harvests from a single plant, reducing food waste and increasing your garden’s yield.

To further your sustainable efforts, always amend your garlic bed with rich, organic compost before planting. This provides slow-release nutrients, improves soil structure, and reduces the need for synthetic fertilizers. Mulching with straw or shredded leaves also helps retain moisture, suppress weeds, and regulate soil temperature—all eco-friendly wins!

Frequently Asked Questions About Garlic Plants Flowering

Why is my softneck garlic flowering?

If your softneck garlic sends up a flower stalk (bolts), it’s a reaction to stress. This can be caused by extreme temperature swings, drought, or nutrient issues. Cut the stalk off right away to help the plant redirect its energy back to the bulb.

Can you eat the bulbils from a garlic scape?

Yes, you can! The bulbils have a potent, fiery garlic flavor. They are quite small, so they’re best used minced in dressings, sprinkled over dishes like a spicy garnish, or infused into oils.

Does cutting the scape harm the garlic plant?

Not at all! In fact, it helps the plant thrive. Removing the scape is like pruning a fruit tree—it directs the plant’s energy where you want it most, which in this case is into growing a big, beautiful bulb underground. The plant recovers very quickly.

What if I miss the window to cut the scape?

Don’t panic! If the scape has already straightened out and become woody, it’s still better to cut it off to help your bulb. The scape itself won’t be as good for eating, but you’re still doing your future garlic harvest a huge favor.

Your Garlic Adventure Continues!

There you have it—everything you need to know when you see your garlic plants flowering. What at first seems like a mystery is actually one of the most exciting moments in the life of a garlic grower.

Remember these key takeaways: that curly stalk is a scape, not a problem. Cutting it when it has one or two curls will give you bigger garlic bulbs and provide a delicious, gourmet ingredient for your kitchen.

So embrace the scape! See it as a sign of a healthy, happy hardneck garlic plant and a reward for your hard work. Now go out there, snip with confidence, and enjoy every part of your amazing garlic harvest.

Happy gardening!
