Around August 20th, I planted coleus and snapdragons in a Park Starts block, set between my minis. These plugs are similar to the AG3/6 bound-peat sponges, and work as replacement sponges. At that time (and maybe still not in stock at this time), there was no such thing as a Master Gardener kit for the mini. Anyway, these are slow-growing ornamentals, so wanted to keep my old flower garden until the replacement plants grew a bit.
The lettuce gardens really have nothing to do with the coleus & snapdragons, except proximity. I've grown a lot of lettuce gardens, though.
This first set of images is the products at Park Seed.
Then transferred them to the mini... Easy transfer, since the starter plug simply replaces the sponge in the pod holder.
9 weeks from seed, both snapdragons are in full bloom. These pictures are after cutting half the spikes off and putting them in a vase. (I let the plants get too big because I wanted the spikes.)
