My balcony veggie patch!

It's been more than 3 weeks since I bought the Rockets & Brussels Sprouts seedlings, and all these time they were living in their original tiny containers as I haven't got around to get them their own self-watering planter box!
 

 
After 3 weeks in their small containers, their leaves have started to turn yellow and are starting to fall. So, I couldn't delay their transplantation any longer and have to get moving even when it was approaching mid-winter with the weather getting cold, windy and wet! I planned to pick the Rockets leaves quite frequently, so have decided to plant all the Rockets seedlings into the one planter box, and the Brussels Sprouts will be in another. They are now living inside my mini greenhouse together with my Baby Carrots and Spring Onions.

While I was getting extra potting mix for these seedlings, I decided to get another 2 kinds of salad leaves to join my balcony: Mizuna & Baby Spinach! I also planned to pick their leaves for salad regularly, so have planted both Mizuna and the Baby Spinach into one planter box!

I read on wiki that Mizuna is "highly resistant to cold and grown extensively during winter months in Japan." I thought to myself, "perfect timing to plant them then and I won't have to worry about leaving them unprotected on my cold & windy balcony!" But then I also read that their growth is "vigorous"... Oh dear! the mizuna might suffocate the baby spinach that are in the same container! LOL. I guess I will wait and see if I need to relocate the baby spinach elsewhere later.
