Re the tip on 13 Aug re "savagely clipping" the tomatoes: When tomato bushes are more or less fully grown, flowering and/or bearing fruit, continually prune the bushes, by about 10 - 20% every week (just enough so the pruning matches the regrowth). Prune from the "inside out" ie remove most of the material from the middle of the bush. This opens it out, lets air circulate, reduces wind damage, discourages pests and diseases, and encourages fruiting. Avoid pruning stems which are flowering - they will produce fruit later. PS I forgot to add to my tip about letting fruit drop and self sow for next season - once the seedlings appear, transplant them. Having tomato crops in the same place each year will attract nematodes. (if you do get nematodes, a solution of molasses and water into the soil will often remove them - the molasses slurps them up).

Thanxs for the reply David. I haven't tried the boiling method yet but was going to try is as a option. Might try the topsy turvy upside down method for a bit of fun!

HBP: I would think pouring boiling water would kill everything GOOD & BAD. There are microorganisms that convert humus into plant food and you have just killed them :( I wonder if this is the problem???

Has anyone heard of pouring boiling hot water in the area that is allocated for tomatoes, wait till it cools then plant your tomatoes to kill dieseases in the soil.? I never have any luck!

We have had cherry tomato plant self seed in the garden bed next to our worm farm. It is producing a lot of fruit but quite a lot of the the fruit is ripening when the tomatoes are still tiny (pea sized). Any thoughts on why this might be? I am a novice gardener without the greenest thumb - I should be happy that we're getting any fruit at all! :D

John, can you give more details on the "savage clip" please.

Another tip - split or half eaten tomatoes on the bush - just let them drop. Next year you will automatically have self sown seedlings.

Grown tomatoes for years. Last summer pruned / clipped quite savagely. Results amazing. 5 times the fruit and the more I trimmed the more fruit I got.

I live in the Dandenong ranges, victoria, I am inspired to raise seedlings of tomato rather than plant out seedlings from the nursery. It is August now, so, is this the time to plant the seeds for transplanting to garden in late September early October?

I'm ready to start my first vegie patch with beetroot, lettuce, carrots and tomatoes (applying companion gardening). Can anyone suggest a really good tomato? These so many varieties all boosting to be the best. Thanks!

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.
