Potting Up Tomato Seedlings

Posted on March 14, 2010 at 9:58 PM

The primary group of tomatoes for the 2010 growing season were started February 13th.   They are now 4 weeks old and ready to move up to larger containers to give them more root room and fresh soil.   Tomatoes are one plant that I try to re pot at least once before planting them out in their permanent bed in the garden - because each time they are planted you can place them more deeply into the soil and additional roots will form along the buried stem area.   I started 144 tomatoes on February 13th and with some germination failures, I am now at about 132 seedlings and of those, most are now ready for potting up.   Yesterday I re potted 36 of them and this morning I tackled another 15 before we headed off for the afternoon to go see a movie (Alice in Wonderland in 3-D).   If I can manage to do 15 to 20 plants each evening all through this coming week then I should have them all re potted by next weekend.                                             

                                         

When I am doing some potting up, I like to assemble all the items I need prior to getting started.                                                                 

      

  

     

I use a simple dishpan (purchased from a dollar store a number of years ago) and fill it with my potting soil mix.   I also set out two stacked solid seedling trays.   I stack them because the larger pots filled with damp soil are very heavy and one tray is just too flimsy to safely hold them.   I use solid trays because I want to bottom water the pots while working on the others.   I fill the tray with warmish water deep enough that the bottom holes in the pots will be completely submerged when set into the tray.   The plants, pots, permanent marker pen, and plant tags are also set out.                         

    

  

   

I reuse plant marker tags for varieties I routinely grow, but in these pictures I am potting up some Market Miracle tomatoes that I grew from seed provided by Daphne from Daphne’s Dandelions.    Since these are new to me this year, I need to create tags for them.   I use just one tag for each 6-pack initially, so when I pot up to individual larger containers I have to add more tags so each pot can have it’s own.                              

                        

Each pot is dipped into the soil mix to just fill the bottom area.                    

  

    

 

A tomato seedling is then gently popped out of the growing cell and placed in the center of the pot.   Soil mix is placed around the sides of the root ball and gently pressed firm to hold the seedling upright.                            

                  

 

 

The rest of the pot is then filled with the soil mix and gently firmed in around the tomato.                                                                                      

 

   

 

The pot is then placed in the waiting tray of warm water and allowed to begin hydrating from the bottom.                                                                

            

   

     

The last step is to add the individual plant tags.                                    

        

  

 

Here’s the tray of 15 seedlings I finished up this morning.                         

   

    

 

As you can see, I recycle pots.   A lot of my friends and co-workers know that I reuse pots and save them for me, which saves money and is better environmentally.    In addition to bottom watering, I also water the pots gently just at the soil surface to ensure they are fully hydrated before draining off the water from the tray.   These tomatoes are a little stressed from the potting up process so they were placed on the heat mat and under the grow lights to recuperate.   The two trays of seedlings I repotted yesterday were moved out to the greenhouse this morning – joining the 5 older super early Siletz tomatoes.

    

    

 

These young plants were just as stressed after potting up as the ones I did today but are now quite rebounded.  

 

 

They will be brought into the shop at night but will reside in the greenhouse during the day.   The super early Siletz plants (in the back of the last picture) continue to receive extra TLC and actually come into the house at night, which is much warmer.   The Siletz plants were potted up three weeks ago and are almost ready for another potting up.   Hopefully I will get that attended to next weekend.

                                

 

I have experienced an 8% loss from germination failures for the February 13th tomato planting.   It will be interesting to see how many more I lose to transplanting shock, accident, and/or just failure to thrive or disease.   I plant way more than I need because inevitably some losses will occur - some years much more so than others.   So far, things are progressing well and the potted up plants are bouncing back from the transplanting experience. 

               

Lots more tomatoes to be re potted.  I will be spending my evenings in the shop this week to get them all attended to.

Great post! I must say I've been lax on following your plan... posting about that now. But today I replanted a bunch of my tomatoes that didn't germinate. Late I know, but time will tell if I was too late. Sure hope not.

Love your potting up setup. MIne is more hap-hazard. Whatever works.

I plan to catch up and follow your planting schedule to the T from now on. Thanks!

Looking good, Kitsap! I'm trying to hold off starting my tomatoes for now, per my experience with the timing last year. But my peppers and a lot of other stuff will finally be planted tomorrow.

I started some extra early tomatoes too, but they seem to not be germinating for me. I probably won't plant out the main seeds until the middle of April if I can stand to wait that long.When do your tomatoes typically go out to the garden?

Sustainable Eats - It definitely helps to rotate out the earlier crops to make room for the warm season crops. I have been shuttling things out to the greenhouse very quickly this year because I have more than my usual number of tomatoes this year - over compensating for the bad year I had all around with tomatoes.

Rich - Good to see you! I have already had to modify the schedule myself to adjust for the bird predation on the peas and a delayed start with my peppers . It's all good though - just adjusting to the circumstances.

Annies Granny - It's hard to wait when folks post about starting plants in areas that have an earlier planting out date than your own region. It's smart of you to hold off though so you are ready at the right time in your particular growing climate. Our average last frost date is mid April and so to be ready for that with well grown and hardened off plants I start 8 weeks before in mid February. I am beginning to think I need to treat all of my tomatoes like the super earlies because our summer here has such a brief period of actual warmth. I think I may need to have the plants further along sooner to really get the best chance at a good crop. I am going on six years in this location now and I am still trying to figure out how to get a really decent sized tomato crop. When I lived in central Washington (Grant County) tomatoes grew like weeds because of the sunny warm conditions. Now I deal with mildews, rots, and blights and have had to really change how I approach this crop.

Daphne - When you are planning to plant the main seeds is when our last average frost occurs. I try to shoot to plant out tomatoes (with some protection) somewhere between April 15th and April 30th. This is a month ahead of when I used to plant out when I lived in central Washington.

That's a lot of tomatoes. Mine will get planted in a few weeks when the cool weather crops go outside and I free up some space. Since tomatoes don't get planted out until may 15-30th or so, I have plenty of time.

I'm amazed that you have enough room for this many seedlings. That's a lot of tomatoes! I'm debating whether to use my homemade 4 inch blocker or newspaper pots to pot up my tomatoes for the precise reason that you can't pot them up deeper with the blocker. How many of these will you actually keep for yourself?

When you plant out your tomatoes will you do black plastic and hoop house cover?

I am trying to start a "victory garden" for the first time and found your blog. I am amazed at how much work you put into your garden with a full time job. I am having second thoughts about if it worth all the effort???

hsheather - It IS a lot of tomatoes but some years I end up with almost 50% losses by the time I get plants in the ground - so I hedge my bets by overplanting significantly. In addition, I grow tomatoes for my sister's garden (she lives close in the general area) and I also purposefully grow extras to give to my staff at work.

Thomas - If I did not have the greenhouse to overflow into this many plants would be very hard to manage. At the end of the day I will be keeping for myself 26 plants - 4 Siletz tomatoes that they will be in containers outside ultimately, 4 Celebrity tomatoes that will be in containers in the greenhouse for the entire growing season, and in the regular garden beds - 2 Fantastics, 2 Cherokee Purples, 4 Market Miracles, 4 Early Girls, and 6 Oroma (paste). I will provide my sister with 14 plants - so combined I need 40 for the two of us. I started with 144 plants knowing that I have in the worst of my experiences lost 50% from seed to planting out in the garden (poor germination, disease, transplant shock deaths, accidental dropping of seedlings, and then freak freezes or other problems just after planting out). Assuming a bad loss year (50%) that get's me to 72 plants. I need 40 which leaves me at least 32 plants to give away to my staff (11 people) and my coworkers. This is pretty much the minimum amount I would want to have and plans for the worst case scenario losses. So far from seeding to the start of potting up - I have suffered an 8% loss. I expect to lose more in the potting up process (always happens) but so far this is turning into a fairly low loss year and I will have alot more seedlings to give away (or pot up in more containers!) . I could plant less and just not give the plants away if I suffered alot of losses but everyone enjoys the plant give away so much I would hate to have that happen.

Sustainable Eats - For the past two years I have been using the red plastic and then I cover the bed in plastic using the tomato cages to drape the plastic over rather than hoops. Black plastic works well too but I am liking the growth I am getting with the red plastic and plan to keep using it. I leave the clear plastic cover on until the weather really warms up and is stablized. Here's the url for a picture of the tomatoes last April shortly after I planted them out:

Firsttimegarden - Goodness, I hope nothing I post discourages you. I DO spend alot of energy and time on my garden because my goals and experience are quite high. I never started out that way though and certainly my goal of 100% vegetable production is not what everyone should necessarily aspire to - particularly when you are just getting started. Rather, I think it best to start small and enjoy some success, grow your skills and find out just how much more YOU want to do. While I hope sharing my experiences with others proves useful, nothing that I do should be taken as a prescription of how it should be done for anyone else. Our gardens should be tailored to our individual goals, needs, energy levels, and lifestyles. For me, my garden is not just about producing food - it's also where I spend time relaxing, getting exercise, and being outdoors. I enjoy the time I spend there - so I do it willingly. During the garden season I average about 4 hours over the course of a weekend in the garden and less than a half hour each weekday between harvesting and minor chores. Some weeks more - some less but that is a typical week. Someone with a much smaller garden can easily cut that more than in half and still have a great harvest. Please do not be discouraged, plant a small garden and enjoy it! Learn and decide how much more you want to do from there.

I grow Juliet tomatoes in large pots(5 and 10 gallon size) on my pool deck. Try some different varieties that do well in your area(ask at the gardening center) and see what does well for you.

It gets real hot in my part of Texas and Juliets are like small cherry tomatoes... they are so good that I eat them off the plant while I am gardening. Try it, you'll like it! And write and let us know how and what you are doing successfully and unsuccessfully.

I just went to your profile and saw you are from Dallas. I'm from Plano. So I definitely recommend the Juliets because the heat of the summer won't affect them too much. Another tomatoe that does well is Celebrity, a larger juicier tomatoe.

Locally, try Northaven Gardens, Calloways, Home Depot and Lowes.

I'm another re-user of pots. When we buy plants for the village flower-beds I always get to take the pots home!
You've got some very perky toms there.

GarlicMan76458 - What helpful info for Firsttimegarden!

Kath - It's amazing how many perfectly good pots end up in the trash. The tomatoes really are looking pretty good so far. I potted up another26 last night but have another pretty sizeable group yet to repot.

Those tomato plants look excellent! Good idea to save labels from year to year. My siletz died the other day, poor fella. I started another yesterday, it is still fairly early to start tomatoes here. They are not planted out until mid May so maybe I will still get some early tom's.

Dan - Sorry to hear about the demise of your early Siletz. :( He was looking pretty peaked in your last photo update on it. I repotted another 26 tomatoes last night and was quite merciless... culling quite a few less than strong seedlings. It sounds like you have more than enough time if you start now to have an early tomato ready by your planting out date.
