From a crop (3-4 plants) of tomatoes ( I mainly grow Cherry) a lot fall on the ground - grub holes etc. In a few weeks/months time heaps of seedling come up. I just transplant them. I can grow tomatoes all year round.

Another method is to just cut slices and place them in the soil and cover them over. Or just take a tomato or a few if small and squash them up in a tray of water - in a few days they will ferment - leave for a few days. Then plant the seeds or separate the seeds and dry them out and keep for later on.

I have read that you can pinch out the laterals (the new shot where the leaf joins the stem) of tomatoes and put that in water and start a new plant. Maybe try that. Can only give it a go or buy some seeds from :The seed collection company" - out of stock at the moment. 200 seeds for $1 + postage.

Yes, doing that really works and I have been doing this all year. I also grow plants from tomato slices placed in seed raising mix. Wonderful results.

Hi there, to tie up all my tomatoes etc I have used an old cotton/polyester sheet that I have torn into strips about 2cm wide. You get heaps of “ribbons “ and can even buy an old sheet from vinnies for $6. The polyester makes them last and they are soft on stems unlike twine and the like. Also old stockings are excellent! Cheers.

I have used old clothes sheets towels all my life. I'm now trying a couple of posts with wire mesh between them. Train the plant in and out of the wire mesh and can use twine etc to support them also. Saves having dozens of pieces of cloth.

Hi I love tomatoes but don't have any luck growing them without white fly or aphids impregnating them. I've tried white oil but with no luck. Does someone out there have the solution as I love growing them and especially eating them. Cheers

Try a mix of LUX soap flakes. Mix 2 table spoons of flakes with 500mls of warm/hot water. Then mix with 5 liters of water and spray both sides of the leaves - do this every 4-5 days. Do the leaves curl up and not grow? Try growing in a different spot. .

Hello, is it too late to sow tomatoe seeds now (mid October)?

You could probably grow tomatoes all year round. Maybe better to plant some good strong seedlings - like about 6-9" tall. Next year plant a bit earlier. I transplanted some small seedlings out 2 days ago. If your soil is nice and fertile mulch around the plants and keep the water up to them.

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.
