Sounds like someone took it. Should have picked it Sat - they will ripen up inside once they start showing some colour.

Mike, yes. That's what I thought... I took yr advice and pick them as soon as I see them start to ripen now. (Can they be picked green to ripen indoors?)

They need to start to change colour before picking. Best to leave on as long as possible if you can.

Hi I'm building a small 90° double skinned tunnel house on the Nthn side of shed. I have Defiant VF2/PHR seed and wondering the earliest I can raise seed for planting.

Don't really know what a double skinned tunnel house is - a hot house?? I have no idea what Defiant VF2/PHR tomatoes are. I suggest you go to NZ cool/mountain climate zone - tomatoes and read the whole article. It is there if you read it - it is pretty simple - it says plant seeds (S) in Oct Nov - and (T) transplant seedlings in Dec Jan.

We have recently moved from the Derwent Valley in Tasmania to Sandstone Point in Queensland. We formally had to plant our tomatoes under glass and never succeeded in having fruit in time for Christmas.Now we have room for a few raised beds whereas we had acreage in the valley; I'm wondering if, in this warmer climate, I can have tomatoes year round.

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.

I am also from the Central Highlands, though this will be my first year trying tomatoes here. A lady with many years of gardening experience recently told me that tomatoes shouldn't be planted out here until Melbourne Cup day (5th November). It's simply too cold before then, especially overnight, and late frosts are still possible in October. For best results you should raise seedlings beside a sunny window or in a greenhouse in late September - early October, to plant out in early November. Or simply buy seedlings from a nursery - this is a much easier option but the number of varieties they sell is limited. I have researched on cold-tolerant varieties for this season and here are three that I am trying this year: Siberian, Stupice, and Swift. You may want to try to look for these varieties as they will probably be better adapted for this climate. Generally, any variety from Northern Europe is probably better to plant than typical Australian varieties, which are bred for hotter climates. Finally, make sure you are feeding them correctly. A high Nitrogen fertiliser is necessary early on, but once it puts on flowers you want to only feed it with one high in Phosphorus and Potassium. There are very few of these fertilisers that seem to be available at the big box stores (many have way too much N) but something like liquid potash or a 'flowers / bloom' labelled fertiliser should work. Make sure to include some organic fertiliser or organic compost when planting out your seeds / seedlings as well, so that your soil is not deficient in trace elements. I hope at least some of this advice helps and that you end up with a bumper crop this year. Tomatoes are probably harder to grow here than elsewhere but I have also been told there are less pest problems than up towards the tropics. Best of luck!
