Fish emulsion is good for root development but not good for leaf and flower/fruit. I use compost, dynamic lifter and powerfeed liquid fertiliser. I use seasol when transplanting seedlings to help prevent root shock. Occasionally use Seasol after that but not much

Tomatoes don't like to be planted near cucumber and capsicum plants. It is also recommended not to plant tomatoes in the same patch as cucumber and capsicum plants for a few years afterward. I am hazarding a guess to say that this maybe a cause to your problem.

What I have found is the plants are getting to much nitrogen in the soil mix... Therefore :- look at burning some green material( once it drys out with paper etc) or buy a bottle of POTASH, and mix into water, and give regular feeds of it. This counters the non- flowering stage, and kick starts ya fruiting cycle on your plants ! I had the same problems years ago, and a old bloke passed this trick onto me. I now use potash to self induce my passion fruit vines, with the best results ever seen and recorded for the fruiting vines around us here.... # my own dad swore by the use of potato e manure on his! but I never found it doing much for my plants! until meeting another old hand from the market days of yesteryear. Hope it helps ya..

Sadly I can't offer help, but I have had the same problem. Above ground, mulched garden bed, seasol & water regularly. Plants receive lots of sun & are planted with capsicum, with lime & lemon plants nearby.

We have planted 5 Royal Flush Tomatoes bushes and they are thriving a producing an abundant crop. However, internal (all bushes are planted on the outer edges of the garden is a circle) all leaves and branches are dying, being eaten and there a black egg like things on a lot of the tomatoes and leaves. Some tomatoes in the inner circle are also being eaten? What can I use to spray? thank you

is it too late to plant tomatoes from seeds ?

Hi I planted Zucchini, Cucumber and Tomatoes in September, and they don't seem to be getting any higher than 40cm...they are fruiting, but I find it unusual that they are not higher now...Should I rip these out, and start again.

Sam, We are borderline cool to temperate. We find that Roma will be later than cherry tomato type or beefsteak type. Try some Powerfeed Red for vegetables and also some potash to boost growth and flowering.

I read somewhere, but I can't locate the source, that over fertilising produces lush foliage but inhibits flowering. Have you been smashing the fertiliser? That includes Seasol and Powerfeed too. Do a little research on nutrient needs for tomatoes. I do know that as they begin to fruit they benefit from a potash rich dressing.

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.
