What a difference a month makes.
If you remember from a previous entry, I had put some pumpkin seeds in pots in the hopes of not having to cart any more of the fruits back from Belgium. They had already germinated and seemed to be getting along well. A couple of weeks ago, I was able to transplant the seedlings to larger pots: four were put together in a very large pot, 43 cm diameter by 35 cm tall, while the remaining five seedlings were spread out in smaller pots.
Eight of the seedlings, including the four you see here, continue to do well, but one seems to be struggling a bit; the runt of the litter, no doubt.
I have no idea if this is considered to be a good way to grow pumpkins, but it's worth a try. Each pot has a bottom layer of lava stones, to promote drainage, with a soil mixture of horse manure and potting compost.
