Anyway I left my Paris Market carrots to themselves after a few thinnings and only now are they really starting to get larger, way behind schedule. It's because I've been busy with other things and not applying Powerfeed. Next time I'll use slow release granules. Also I would probably need a much wider/larger container, because while there's been zero issues with the depth of a windowbox they do need room to expand and after thinning you really don't get many.
Seeing as it's getting colder I might sow some silverbeet or spinach in the boxes, or as they're an heirloom variety I could just let the carrots go to seed.
Right now the only plants I'm really keeping an eye on are my cat's continuous sow pots of cat grass, and the rosemary cuttings growing into bushes in some paper cups. I think one died but the other is having new growth and might want a bigger pot.
