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.

Of course there are lots of factors (soil watering etc.), I\ll point out a few you may have issues with. I'm a little concerned about your night time temperatures harming the growth or steady growth of your tomatoes -- in addition Blossom drop will occur in if daytime temperatures are warm but night temps drop below 55 F. (13 C.) -- a condition that can easily occur in a greenhouse in winter. When you look at days to harvest for tomatoes -- they are assuming spring/summer growing -- which means the NUMBER of daylight hours is HIGHER. Your area may drop from 12 hours of daylight in summer to 9 in winter.... that's a big difference. Additionally the INTENSITY of the sun is not as great in winter as it is in summer. This means the plant is not collecting as much light. I would GUESTIMATE you need to at double the DAYS to harvest to account for your growing conditions. If you decide to go forward I would opt for varieties that tend to grow well in colder climates that NATURALLY have less intense sun and shorter days (or install lighting if you don't have it and perhaps some heat). REMEMBER your soil temp needs to stay at about 16c -- so if your pots are on the ground or if you are planting directly into the soil, the cold may creep into the soil from below. There are specific tomato varietals bred for cold hardiness which will tolerate conditions at or below 55 degrees F. (13 C.). The best choices for colder climates are short to mid-season tomatoes. These tomatoes set fruit not only in cooler temps, but also reach maturity in the shortest number of days; around 52-70 days. I would look to some indeterminate cherry or plum size tomatoes (so small tomatoes) with very low days to harvest. I have never grow this tomato -- but -- Originally developed for cool rainy nights, Quedlinburger Frühe Liebe (or as I like to say, QFL) is a German heirloom tomato variety that’s ready for harvest in just 40 days after transplanting (!!!) and keeps producing until killed by a freeze. This makes it quite an amazing all-season plant and a real keeper in the garden if you’re prone to cold snaps. QFL is sweet and flavorful with small, juicy red fruits ==> tomatofest (internet site in the USA) says : Old German potato-leaf variety means "Early love of Qued Linburg". Small spindly vines produce 1 1/2-inch, round, 4-lobed fruit in clusters of 4. These tomatoes have great flavor with good acidity. Developed for cool rainy nights. Prolific even during colder summers. **** you really need to review the conditions in your green house -- day and night time temps, hours of sunlight --and you need to choose your variety wisely -- and even then, this might be difficult -- a lot depends on your greenhouse.
