Every year it seems, I adjust my tomato seed planting schedule. This year is the latest I’ve ever started my tomato seeds-April 5th. Still trying to tweak it out about when the best time is to start them. If I plant seeds too early, the plants will get too tall before I transplant them outside in wall of waters. Last year I started seeds March 29th. So we will see how they do.
A couple of things have allowed me be able to start them later and get them in the garden earlier.
First, since I changed to Batch 64-Moonshine soil mix (from Agua Fria Nursery), the plants take off growing like a rocket as soon as they germinate. The list of ingredients in it is unbelievable. Once the seeds germinate, there is enough nutrients in this soil mix to basically fertilize your seedling for 6 weeks without adding anything else (except maybe liquid seaweed and Vitamin B at transplanting time to reduce transplant shock). Now I can plant them outside in 5 weeks instead of the 7-8 weeks in years past.
Secondly, I now start my seeds in these germination trays (see pic) where the cells are close together. The trays being shallower, seem to speed the germination process too—less soil to heat. These are a 20 row seedling flat.
Thirdly, it seems to be getting warmer sooner in the spring here in Santa Fe or at least that is my experience. Using wall of waters to protect the young tomato plants from cold nights, I was able to transplant my tomato plants outside on May 3rd, shaving 13 days off the ‘frost free’ date of May 15 that we have here in Zone 6b. They did just fine in their wall of waters. But last year we were in a warm drought and this year may be different with all the precipitation we got this winter. We’ll see.
And lastly, maybe, just maybe, I’ve become a better gardener through the years…
