Do I Soak Nasturtium Seeds Before Planting? A Gardener’s Perspective
Gardening can feel like an endless experiment in patience and faith, especially when you’re working with nature’s tiny treasures like seeds. Over the years, I’ve learned that the smallest details can make a world of difference in the success of my plants.
Nasturtium seeds, with their unique round shape and hard outer shell, are no exception. I’ve often asked myself, “Do I really need to soak these little guys before planting?” It seems like a minor step, but as any seasoned gardener knows, sometimes those small tweaks have the biggest payoffs.
So, what’s the deal with soaking nasturtium seeds? Is it a trick to speed up germination, or just another unnecessary step in the gardening world? Before I started soaking, I had plenty of questions. Would it actually make a difference in the health and growth of my plants? And if so, how long should I soak them? These are the questions I want to tackle because, let’s face it, we all want to get the most out of our gardening efforts.
By the end of this blog, you’ll understand the science and reasoning behind soaking nasturtium seeds, and whether it’s worth adding to your gardening routine. I’ll break down my own experiences and tips, giving you a roadmap for success. Regardless of your experience level, this guide will assist you in making the most informed choices for your nasturtium garden.

Why Soaking Seeds Matters
Soaking seeds isn’t just some gardening folklore—it’s a legitimate method that can help speed up germination and improve plant health. Nasturtium seeds, in particular, have a thick, somewhat impermeable seed coat. The coating makes it tougher for water to penetrate and initiate the germination process. If you don’t soak the nasturtium seeds, they may take a long time to sprout, potentially leaving you waiting for days or even weeks.
Let’s look at the science behind it. When you soak the seeds, you soften that tough outer layer, allowing water to get to the seed embryo faster. It’s like pre-soaking beans before cooking—it helps them swell, absorb moisture, and eventually sprout more quickly. Essentially, soaking gives your seeds a head start. In my garden, I’ve found that this small step leads to a more robust plant from the very beginning.
Benefits of Soaking Nasturtium Seeds
- Faster Germination: Seeds sprout more quickly once they’ve absorbed moisture, reducing the time you spend waiting.
- Higher Success Rate: Soaking can help ensure that a higher percentage of your seeds actually germinate.
- Healthier Plants: Well-hydrated seeds often lead to stronger, more resilient plants that can withstand pests and diseases better.
| Pros | Cons |
| Faster germination time | Additional step in the planting process |
| Improved success rate | Requires careful timing |
| Better hydration for seeds | Possible over-soaking risks |
How to Soak Nasturtium Seeds: My Go-To Method
Over the years, I’ve developed a simple routine for soaking nasturtium seeds. It doesn’t require any fancy equipment, just a bit of planning and patience. Here’s how I do it:
- Gather Your Supplies: You’ll need a shallow bowl, some water (I prefer room temperature), and, of course, your nasturtium seeds.
- Fill the Bowl with Water: I usually fill the bowl just enough to cover the seeds. Room temperature water is ideal—nothing too cold or too hot.
- Soak the Seeds: I let the seeds sit in the water for about 12 to 24 hours. I’ve found that this time frame softens the seed coat without over-soaking them.
- Check the Seeds: After soaking seeds, the seeds should be slightly swollen. If they look ready, drain them and plant immediately.
The key is not to leave the seeds soaking for too long. Just like with anything else, there’s a balance to be struck. If you leave them in water for too long, they could start to rot instead of sprout.

When You Might Skip the Soak
While soaking works wonders in many cases, there are times when you might choose to skip it. If you’re planting nasturtium seeds directly outdoors in warm, moist soil, you might not need to pre-soak at all. T
he natural moisture in the ground can provide enough hydration for the seeds to break through their hard shells on their own. Additionally, if you’re dealing with older seeds, soaking may not bring them back to life as effectively as you’d hope.
In my experience, soaking is particularly helpful for indoor planting or in regions where the soil tends to dry out quickly. But if you live in a more humid climate, or you’re planting in the height of the growing season, you might find that your seeds germinate just fine without the extra step.
| When to Soak | When to Skip Soaking |
| Indoor planting | Direct planting in moist soil |
| Dry or arid climate | Humid environments |
| Older or harder seeds | Fresh seeds in warm conditions |
Alternative Methods to Enhance Germination of Nasturtium Seeds
Getting nasturtium seeds to sprout quickly and evenly requires more than just planting and waiting. Since these seeds have a tough outer shell, breaking through that barrier can speed up germination. One effective technique is scarification, which involves gently nicking or sanding the seed coat before soaking. This process allows moisture to penetrate the seed more easily, leading to faster and more reliable sprouting.
Beyond basic soaking, gardeners often use natural additives to boost germination. Some options include:
- Chamomile tea – Acts as a natural antifungal, preventing seed rot.
- Hydrogen peroxide solution – Helps disinfect seeds and promotes quicker sprouting.
- Warm water soak – Softens the seed coat for easier germination.
| Method | Germination Speed | Ease of Use | Best For |
| Scarification + Soaking | Fast | Moderate | Tough-coated seeds |
| Soaking in Chamomile Tea | Medium | Easy | Preventing rot |
| Direct Planting | Slow | Easiest | Minimal effort |
While direct planting works, combining scarification with a soak in a natural treatment enhances germination rates, leading to healthier, more vigorous nasturtium seedlings.

My Personal Verdict on Soaking Nasturtium Seeds
After years of trial and error, I can confidently say that soaking nasturtium seeds before planting makes a noticeable difference. The faster germination and stronger plants speak for themselves. But the decision ultimately comes down to your specific gardening situation. For me, I’ll always soak nasturtium seeds when I start them indoors or if I’m planting early in the season. The results just make it worth the extra step.
That said, gardening is as much about intuition as it is science. Sometimes, you have to try things out for yourself and see what works best in your garden. So, if you’re wondering whether to soak your nasturtium seeds this season, I encourage you to give it a shot. You might just find it’s the key to a more vibrant, thriving garden.
By taking the time to soak your seeds, you’re setting yourself up for gardening success. A small investment of time and effort could lead to big rewards when your nasturtium plants burst into full bloom. Happy planting!
