Read the top of the page for planting times. Water today and tomorrow stick you finger into the soil 75 mm, if your finger is wet then you don't need to water. Small waterings to start with and then increase it as the plant grows.

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.
