Hi guys,
Complete newbie here!
A few months ago I started with a few veggie seedlings just to experiment (and see if I enjoy tending a veggie garden).
I planted peppers, spinach, strawberries and cherry tomato seedlings directly into the ground. This was end November.
We had water restrictions and a very hot & dry summer, so they suffered a bit. Growth was slow and insects or birds terrorized my veggie patch.
Few weeks ago I decided to transplant what was left (only peppers, strawberries & spinach) into pots, which allowed me to move it into a cooler part of the garden during the hot months, and move it to the stoep when the winter freeze comes, and finally to water it better.
I've used potting soil and compost for the pots. Also bought the fish fertilizer which I'll administer about every 6 weeks.
Here is my biggest spinach plant which is still too small to harvest (I guess)

You'll notice the leaves have some damage - I'm not sure if this is caused by bugs or birds?
Also, you'll see some small tomato seedlings coming up on the sides. This was an experiment to see how easy tomato seeds grow from a slice of fresh tomato (very easy!). I'll transplant them when they're bigger.
And here are my peppers, also too small to harvest

You'll notice similar leave damage.
The strawberry plants are still alive, although not bearing fruit currently (not in season)
A few more questions:
What can I do to accelerate growth further? These plants are almost 5 months old already!
Should the peppers, spinach and strawberries be able to survive the winter?
I also want to plant onion and swiss chard seeds. Is this a good time of the year?
When is the spinach ready to harvest?
Any advice appreciated as always!
