More Seed Starting Tips

Gail Cook has been a Master Gardener since 2003. She has worked at The Raincatcher’s Garden for many years and now has a new job with us. She is planting herb, flower and vegetable seeds. It’s a perfect job for her; she a nurturer. 

Gail, I heard you are doing a wonderful job with seed starting for the edible landscape. In December, I had the privilege of hearing from Jim about his seed starting methods.
I was wondering what equipment you use. Seed starting mats? Grow lights?Any tips you want to give our blog readers about seed starting. Do you mind letting me know of the potting mix you use? Do you purchase or make your own?

Hi Ann, How nice to hear from you!

Honestly, I’m in one of my happy places starting seeds and, with everyone’s help, we’re doing well with the seedlings. I don’t even have a back yard these days, just a long narrow brick patio with a bit of sun and a small utility deck with a 4-shelf zip-up greenhouse.

I have one warming mat and it does speed things up. To save time ( I can plant 72 seeds in minutes this way)and space, I’ve been starting most seeds in 72-count plug trays from amazon in clearance and seed starting mix from Walmart. There are 300 plugs germinating on my upstairs bathroom counter now. Then I pot them up in 4” pots right after germination.

I’m still working on mixing potting soil with perlite and/or vermiculite to get a lightweight soil because I haven’t found a brand I love yet. Northaven Gardens has a recommendation in a recent email that I plan to try when I can look it up. Some seeds go straight to the greenhouse once planted, depending on weather. It can be tricky to keep the soil at the just right level of moisture but we haven’t had a problem with damping off, even though they stay fairly wet with almost daily misting.

I’m also experimenting with diluted organic liquid  fertilizer after the 2nd set of leaves appear to get them to transplant size as quickly as possible. This requires patience. 

 The Raincatcher’s greenhouse is a huge help during colder weather, as are the other edible garden volunteers who check on the seedlings. I’ll come back to you on soil mixes. Don’t hesitate to remind me. Busy time at work just kicked in, another reason I enjoy the seeds.

Best, Gail

Gail writes again:

A couple more tips: Peat moss can be difficult to moisten so add water to the seed starting mix before filling pots. A bucket and your trowel are useful for mixing. 

When using a heat mat indoors or a greenhouse on warm days, monitor closely, preferably twice a day. The soil dries out very quickly and seedlings will fail to germinate or grow. Seedlings should be removed immediately from the heat map as they germinate, as they no longer need the warmer temperatures.

Gail’s Greenhouse

 

This little greenhouse is from Tuesday Morning  and is on it’s 4th winter. It is in a protected area and doesn’t get much direct sun. There are a few patches over tiny holes but it still works. I’ll probably buy another next year.

 My husband has started referring to the seedlings as our children because they are taking up so much of my time.                                                        

 

 

 

 

If you are feeling overwhelmed with all the information and purchase recommendations, Gail suggests starting with easy lettuce and greens for the first season. Simple can be better for beginners. Have fun!

Thank you, Gail.
