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.

For tomatoes what is the best ph level

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

My tomato vines are full of fruit, all of it green. I've often had the problem of ending up with lots of unripe fruit at the end of the season so I was wondering it there is a sure-fire way of ripening the tomatoes on the vine before the first frosts?

My dad said he used to pull the whole plant out and hang it in a shed and the tomatoes would vine ripen then finish off on the windowsill.

Ethylene gas ripens tomatoes and some other fruit. Add a few bananas to them. Suggest you read up about how to ripen tomatoes on the internet. Read different articles. Also see if you can start your seedlings earlier in future so that they grow/ ripen earlier in future.

Hi. Thanks for the info which was informative. I tried last year to grow tomatoes and failed miserably. The bottom of the fruit was black and I have been advised this was overwatering and lack of calcium. They were in 15L pots outside and exposed to a fairly windy area. This year I have a geeenhouse and a bit more knowledge thanks to the likes of you:). I am just deciding what to grow in the greenhouse and in my small vege patch but definately have tomatoes on the list a bit later in the year, although I might try growing some now and keep in the greenhouse. Appreciate your comments and advice thanks. I live in Somerville near Howick. Cheers Derek
