You can grow all year round. Summer can become a but hot and very wet (as in inches of rain in hours) -use mulch around the plants. Best to grow a crop from late Feb for a winter picking crop and plant in mid August for crop into summer. Or even plant a succession crop each time also - 4-6 weeks between each planting. Only need 2-4 plants each time. .

I have sown various and different tomato seeds (climbing and other) trays in the greenhouse and now they are seedlings. 1. How big must they be before I plant them out(sown 25/5/18) and 2. How can I stop bugs/insects from attacking/destroying the tomatoes? 3.I want to put up a frame and netting/shade cloth all around but my concern is that if I do so then how to the tomatoes get pollinated if the bees can't get to them (and other plants)? :( Thanks.

Use derris dust or some other home made organic spray - look on the internet. Plant as soon as they have a few true leaves. They grow better in the ground than in a pot. Tomatoes are self pollinating - by the wind - or give them a gentle shake. Google about this if you like. Try Greenpatch Organic for vegetable netting 3.5 and 6m wide $4 and $7.50 by the meter. We are going into cool/cold weather so next time plant earlier (Feb- March) or leave it until spring time.

My tomato seedlings keep shrivelling up and dying, they grow really well and then one day they justshrivel up. When I look just below the soil they seem to have a brown part on the stem, almost like it has rotted? Someone suggested it was some type of worm?

Hi ,im out at West Wyalong and i thought it was to early to put in tomato seeds. We are still having warm weather so can you start early plants. Going off the sowing chart it says not for a couple of months. Not sure but advice most welcome

Tomatoes are frost sensitive. You can grow from seed trays indoors about 6 weeks before the end of winter and then plant out when the danger of frost has passed. They grow best under shade cloth as the hot summers are too testy for them and they get sunburned. Best to water well, in composted well drained soil. Stagger planting times for long harvest but best to finish planting in December. My plants are still producing fruit but with frost coming, producing days are numbered.

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.
