Try googling what NPK fertiliser tomatoes like.

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.

For tomatoes what is the best ph level

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

I live on the North Shore, Auckland and have done container growing for several years now, This is the third year of growing tomatoes on a large scale - predominantly determinate varieties. I source my seeds from Kings Seeds who supply a determinate variety called Sub Arctic Plenty which I have experimented with variable results. All plants raised indoors, gently hardened off then potted out into 15L tubs. I use 50/50 new compost/previously used container soil from a non-tomato pot mixed well with added slow release fertiliser and half a cup of powdered eggshell.. The top is mulched with straw and 4 marigolds to attract the bees. They also need a 5ft stake. Generally the plants like the morning and late sun and need shade from the glaring hot midday temperatures. Each year I am growing them earlier to avoid the heat of summer. The pots on the decking facing North fully exposed struggled, the pots that were shaded midday grew much better. Next year I plan to plant out in July/August and see how they get on then. They have a mild taste, personally I prefer the richer flavours of the dark toms but they are good for dehydrating. I also found that they prefer dryer soil than some of my other varieties. I liquid feed them once a week using a litre of water. Don't let them stand in trays, they need full drainage. Any run off from the trays I use on something else (the pineapple sage is very grateful). Spay every part of the plant with a brew of bicarsoda to pre-empt and control powdery mildew weekly. Please let me know if you want any other info - happy to share. Let me know how you get on.
