I live in the Coastal Overberg Region and planted my tomato seedlings in containers during March. They seem to be doing well at 50cm. Have I planted too late to enjoy more than one harvest?

Plant seeds Aug and transplant from Sept to Nov. If you planted indeterminate kinds of tomatoes they will crop over several months.

Greetings! I'm hoping to start a small organic vegetable garden. Would now be ok to plant tomatoes, lettuce, onion, green pepper etc. I have a partially covered courtyard so I have the option to plant in containers too. Our winters here are not too bad, lovely days, cool/nippy evenings. Please advise. Regards, Kerry.

This website is for people to look up when to plant different vegetables etc. Work out your climate zone and check each vegetable when to plant.

Had to say what your problem is, too much water, too little water, too hot. Maybe start again.

6.5 is a common pH level for vegetables and works for tomatoes.

You can look up the germination (seed hatching) temperature for various vegetables online. Compare this temperature to your soil temperature (even your air temperature to get an idea) -- the germination temperature needs to be met and sustained for the seeds to germinate (in addition to water, soil and presence of light for some shallow planted seeds). Most likely you will still benefit from starting indoors -- it all depends on temperatures AND which veggies you are planting - some veggies seeds have fairly low germination temps - beans, chard, mustard etc. Other veggies have very high germination temps: tomatoes, peppers etc. Remember that the germination temp needs to not only be met, it needs to be sustained. Since you can control your inside temperature - I would start my seeds indoors -- and potentially add a heating pad under the seedling tray. If you plant outdoors you can use a tarp to help warm the soil; I prefer clear elevated about 6" above the ground (like a green house) to help warm the soil when the sun hits it
