I have never grown Roma acid tomatoes before. At first I watched the plants growing in leaps and bounds day by day - then they seemed to come to a standstill. I am in Cairns. But this morning went out to look them over and noticed that one plant has 3 tomatoes on it but the plant itself does not look happy. Trish

We had a great crop of mixed tomatoes this year but could you please tell me why the skins on the tomatoes are tough. Many thanks

that depends on the variety you are growing and where you live. In Canberra the nights are COLD and I notice some of them have very tough skin. Now I grow one with no name, Grossie Lissie, s. Marzano and Jersey Devil, they all good.

they would be hybrids which are bred for a tough skin for transport so they don't bruise.

About 7 weeks from when the fruit first appear, varies depending on soil and climate but that's the average.

Hi .Roma normally put out a lot of laterals. If they are all left on the vine not much will ripen quickly as the plant makes more trusses. To ripen I pinch most if not all of the new laterals off , the plant put energy into ripening the green tomatoes . A week or so later new laterals appear with more flowers etc. I do this with all indeterminate plants to make them ripen when I want them to .

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.
