Foolproof Cucumber Seedlings- You Can Grow That!

The other day I blogged about the fun I’ve had this year with growing tomatoes. I’ve been in kind of the same mode with cucumbers (and pumpkins, and squash, and peppers, and several varieties of flowers). There’s a background story to my seed starting obsession that I have to share. In February one of the women who I work with in my job as an adaptive gardening specialist at Bass River approached me with a package of cucumber seeds that were dated 2011 and asked if we could grow them. I thought that starting them successfully was a long shot but I also saw the challenge as a chance for a fun learning opportunity. We decided to plant some of the seeds in pots of seed starting mix, and to try to germinate another group on a damp paper towel in a jar. Within a few days we had a jar full of cucumber sprouts that were flourishing. The seeds planted in the soil never did germinate, not one. We transplanted the sprouts to a container of soil and now we have little cucumbers growing on a trellis in a sunny window. So, we concluded that a little bit of humidity goes a long way in sprouting seeds and even older seeds might respond to this special treatment. I’ve been reading a lot about adding humidity to help the germination process and I brought the idea here to my home garden.  I’m growing all kinds of things in plastic bags and jars!

Here’s a step by step description of my easy foolproof way to grow cucumber seedlings:

IMG_5338I start with a paper towel, a clean jar with a lid, a water spray bottle, some tape and a package of seeds.

IMG_5343I dampen the paper towel and spread the seeds evenly over it.

IMG_5345Roll it up gently…

IMG_5346and place it in the jar and close the lid.

IMG_5354Then I mark it with a sharpie or as in this case I tape the seed package to the jar.  I did this on April 25th, remember that date!

IMG_5355Here’s what I found when I took them out on April 29th. These are a little bit overgrown, they could have come out of the jar on the 28th or even the 27th.

IMG_5357I gently placed well moistened seed starting mix in cups with a hole punched on the bottom… I don’t usually use paper cups but I had these on hand and the seeds needed to be transplanted right away.

IMG_5360I dug a little hole and placed a seedling in each container with the root facing down,

IMG_5362and just barely covered it with soil.

IMG_5363I put the cups under the grow light,

and here they are on May 3rd. The first leaves are sprouting and the second set is close behind!

They would be ready to go out in a few days if our last frost date were closer. Unfortunately it’s not quite time for tender plants to be planted outside here on the New England coast. I’ll move them out from under the light when they get a little bigger and keep them in a sunny window for a few weeks. When transplant time is close I’ll put them outside in a protected spot for the daytime hours for several days to harden them off (help them get used to outside temps) before I plant them in the garden.

Just to summarize the dates; I started them on April 25th and eight days later their well on their way. That makes the turnaround time from putting them in the jar to being garden ready about 12-14 days.

Guess what that means? You have plenty of time to do this! And it’s easy, and I dare say it’s fun!

I hope that you get some seeds started soon!

Remember, you can grow that!

  1. I’ve seen this idea before, but I need a grow light to have anything live inside my cold, dark house! It’s not really that bad, but it is for seedlings. I like that you grew them in simple, paper cups.

    1. It’s amazing what a grow light does. I’ll probably talk about this is a post soon but I’ve become a pretty big fan of the “plant bulbs”… I did some with and some without this year and there’s a really big difference. Hope you get some seedlings growing!
