Tag Archive: saving leggy seedlings


It’s been a bit over a month since I started my experiment to see if leggy seedlings could be saved by planting them deeper than normal into soil – and I have good news! Don’t throw out your leggy seedling, because so far a lot have survived….

The verdict for the veggie seedlings:

 

Kale – huge success! All three types of kale (Red, Tuscan and Blue) that I’ve been growing have continued to grow and do well. Even so large now I transplanted a couple into the garden. While doing this I found than new roots had formed in the section I had planted up.

Red and Tuscan kale leggy seedlings out in the garden!

Broccoli/Cauliflower – mixed success… some have done quite well, others growing slowly. They haven’t died, but when checked hadn’t formed new roots either… will have to keep watching these ones

Purple Sicily Cauliflower

Silver beet/Ruby Chard and Kohl Rabi – all died. Don’t bother trying to save these ones.

Cabbage – will have to let you know for next time, because unfortunately these were all eaten by snails in the first week…

And in the flower department:

Honesty & Stock: Mixed success – still alive but growth extremely slow

Cornflower & Calendula – huge success! Growing well and looking good!

 

So there you have it. Turns out you can plant up leggy seedlings – some will form new roots and others will benefit from a bit of extra support. Overall leggy seedlings are certainly not a waste!

About a month ago I got quite keen and started my first round of autumn and winter seedlings (see Preparing for Autumn and Winter – New Seedlings post). Not long after this I went on holiday…. Most people would have waited until they came back from holiday before starting their seedlings – but I’ve never been known for my patience. I decided not to leave them outside while we were away in case of extreme weather days, so they stayed under a window inside. I came back to an overgrown mess of leggy seedlings!

I was pretty impressed by the amount of growth, but a lot were just too leggy to plant as they were. A quick internet search about what to do lead to mixed results… a lot of people said leggy seedlings will simply die – just start again. There were a few sites/posts however saying it was possible to plant them up (similar to what you would do with tomatoes) and roots grow in the newly planted section. A whole lot else said the seedlings will rot if you try this… As it felt like such a waste to throw my seedlings away, I thought it was worth a try!

I firstly cleared out all the seed pots that hadn’t germinated at all and then I separated out the seedlings that were ready to go straight into the garden and planted them. I then selected out all the seed pots that hadn’t gone leggy and moved them aside. This really helped to reduce the chaos in the seed trays!

With the remaining seedlings I placed them (still in their paper pots) in the bottom of a standard small plastic pot. Then I filled up around the seedlings with soil to what visually felt like a normal seedling size/length (…the real scientific approach….)

Initial....

...after one week....

...Kale seedlings after two weeks...

Unfortunately I lost a few seedlings to snails in the first week (it really is a constant war… forget and lose the battle) but I’ve put some copper tape around the other pots to help keep the remaining ones safe. Two weeks later and a lot are still going strong! While some have died, there are still many alive and doing well. I’d say a successful experiment so far – more updates to come.

I also have the next round of seedlings are off and running! This time I’m moving them daily to get the best of the sun and so far their growth (and even the colour of the seedlings) has been a lot better.

Next round of seedlings

So yes, initial care is the best method – but is seems not all is lost when it comes to leggy seedlings.
