My tomato vines are full of fruit, all of it green. I've often had the problem of ending up with lots of unripe fruit at the end of the season so I was wondering it there is a sure-fire way of ripening the tomatoes on the vine before the first frosts?

My dad said he used to pull the whole plant out and hang it in a shed and the tomatoes would vine ripen then finish off on the windowsill.

Ethylene gas ripens tomatoes and some other fruit. Add a few bananas to them. Suggest you read up about how to ripen tomatoes on the internet. Read different articles. Also see if you can start your seedlings earlier in future so that they grow/ ripen earlier in future.

Also most fruit take a few weeks from being fully developed to then ripen, 3-5 weeks. Same applies to pumpkin, rockmelons, watermelons etc.

Any advice on best cool climate tomato varieties for a greenhouse in Melbourne between March and October? Thanks in advance

You are temperate, a greenhouse will raise the temperature in it. Most varieties would grow in it. Ask at your local nursery etc.

Hello, what kind of tomato variaties can be grown in East African conditions more so in central Uganda.

Look up on the internet or phone seed selling companies. Go to local nurseries and ask.

If you set your climate to summer rainfall and look in tomatoes, it is right in front of you, plant SEPT TO MARCH.

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.
