With our diverse weather, what watering should we do?And Oblige Brian

It is a bit of trial and error. Have good draining soil. Little plants need little waterings more often, daily, big plants a lot more water less often, 2-3 times per week. General rule dig down into the soil 50-70mm to see how moist the soil is. You will quickly learn that say a crop of lettuce might need 60 sec of watering. Whereas some mature tomatoes plants need 2-3 minutes.

In Berwick Vic. Have grown garlic with great success for years but this year virtually all plants have segmented in the ground pre normal harvest time. Plants are still strong, green and upright although have grown slimmer leaves as they segment. I do not believe I have done anything differently this year. Any thoughts?.

Maybe the hotter weather.

Hello. Our purple garlic is out of the ground. We tie them in bunches with dead stems intact . We take the roots off them. Question: the shed they are suspended in has a moist atmosphere due to the rain today. It has a dirt floor and no doors.Will this moisture cause them to rot or make them susceptible to pests or mites. We have about 800. Thankyou

My experience is with shallot bulbs. I just keep them loose in a pot tray/dish drying tray about 2-3 (??)

I am western Australia perth . I would like to ask you about garlic . Can it be planted in early or mid December, would it still grow to its full potential if planted around that time.thank you very much.

This is the way I see it. They recommend planting May to July for temperate - Perth. The reason is, this is when you will have the best results. Now if you go and plant it in Oct/Nov you will probably produce a smaller crop or no crop. You have to look at your local conditions also. It is like if a seed requires 20 degrees soil temp to germinate why plant it when it is 15 degrees.

Suggest you read all the notes here about growing it, especially the calendar when to plant.

This is a transcript of a article on growing garlic in central Australia (desert). It is on ABC Rural News and may be a help to you. Trials reveal potential for garlic-growing in Northern Territory Posted 7 Oct 2016 MAP: Alice Springs 0870 A trial exploring the capabilities of seven garlic varieties in the red centre is showing some early positive results. Seven varieties of garlic are being trialled at the Northern Territory's Arid Zone Research Institute (AZRI), alongside the standard industry garlic variety, Glen Large. The Alice Springs environment will demonstrate how varieties that have never been grown commercially in the Northern Territory respond to extreme cold and extreme heat. Central Australian Horticulture Development Project manager and researcher Stuart Smith said despite challenges such as poor water quality, the results so far had been positive. "We're hoping, because we're just south of the Tropic of Capricorn, we're just a bit a little subtropical, that we're in the right area," he said. "We've got the right heat profile, right day length and we're able to grow some good bulbs. "If it'll grow here, it'll grow anywhere. "Central Australia is a bit isolated from the rest of Australia so it doesn't have the pests and diseases of the other garlic-growing areas." Plan to get garlic onto market early in season Mr Smith believes there is a market opportunity for garlic that grows early in the traditional growing season. We thought we could get a few varieties to come early on the market, so we can get some good prices for them and replace the imported garlic," he said. The first successful harvested trial crop has reached a stage of maturity that would be ready for market. "It's got a code name called AF. We're getting some good-sized bulbs out of this," Mr Smith said. "I estimate we're getting 6-8 tonnes per hectare."

(ABC Rural: Katrina Beaven) Mr Smith said the early trial results were encouraging despite poor water quality and salty soils. "We have to keep watering them pretty constantly to keep moving the salt out of the root zone," he said. "The water we're using at AZRI is pretty low quality. "Most of the water other people are using in horticulture around the Central Australian region is a lot better quality than this." Mr Smith said the research results would also add value to what was being learned by a grower at Orange Creek Station, south of Alice Springs, who is conducting a commercial garlic trial this year.
