To keep the slugs, caterpillars from Tomatoes and other vegetables away break egg shells up and spread around plants. Works great

We have been experiencing very hot, dry days. Up to 42 degrees Celsius. Could this be the reason that my tomato plants died? They were watered regularly & kept in the shade.

I think it could just be seasonal. My tomatoes were going great (Nov and into Dec picking) and towards the end the whole plant just died off quite quickly. Same conditions as you, hot weather. In a lot of crops you can have early mid and late season varieties.

My butter beans plants are producing lots of beans that are growing and then curling up at the ends. What could be causing this and can i treat it with a fertilizer or a spray? I also have Zucchini that the flower covers all of the end rather then the tip they grow about 3-4 inches and then go yellow and shrivel up?

Research on the internet, what causes curly beans. Go the Gardening know how webpage and read. I think the zucchinis are a bit of a mutated seed or whatever. I had a plant like that, big fat end zucchinis with a big flower. Sounds like the female flowers are not being pollinated. Try it by hand.

Check the plant day and night for grubs.

My tomato bushes are great and promise a bumper crop again this year. As my mother before me, I dig cow manure (from the shop) into the bed six weeks before planting the seedlings. My mother added liquid manure to hers as well.

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.
