The one with a bit of a butt or root looking area. Look at a clump of garlic and you will work it out.

I planted my elephant garlic on the 21st April, a bit late this year and it is i going great never have a problem with it. I usually plant it on the shortest day of the year and pull it out on the longest day of the year. Good Luck

Not sure if Brisbane is tropical or sub-tropical but here is my question... I planted garlic last weekend without realising that it shouldn't be near to asparagus. Could you tell me why please? There's just one batch there the othets are near tomatoes and in a pot.

I planted my garlic in mid April, and it's coming up really well. At the same time, I planted some elephant/giant garlic cloves a friend gave me (grown in his garden nearby). The elephant garlic isn't showing above ground at all. Is this normal that it takes longer to shoot, or did I plant it at the wrong time?

Some bulbs are slower to emerge from the ground. You could carefully scratch around the bulb site with your finger and see if is coming up. The only negative thing I can think of is that the bulbs may have been damp and have rotted. I doubt this.

Thanks Jack. I might have a scratch around and see. I don't think the cloves would have rotted either. Probably I just need to be patient!

Garlic is normally planted as the season cools down and is harvested in late December. It likes a sunny spot but dislikes competition from weeds so keep it well mulched. Consistent watering is also important for the best yield.

Hi I have tried growing garlic a couple of times now. Generally I plant on the 23 March and harvest 23 June. First few times garlic was small except for a couple decent sized ones. Last year, I ended up with one large bulb only, on each plant; almost like a small onion. What would cause this to happen?

Heres an answer for garlic, I grow about 300 plants a year and get good results with about 90% of the cloves coming in at 5cm in diameter plus. Season. Garlic takes up to 9 months to mature. Plant in autumn, late March to May, harvest November to December. Clove selection. Plant only the largest cloves, at least the size of your top thumb joint, I have big hands so I plant cloves 2- 2.5 cm across. Its easy to eat the biggest and the best, its better to plant the biggest and the best. Spacing. I plant 15 - 18 cloves per square metre, 25cm apart in rows 25 cm apart. With 30 cm + paths between 4 rows. It's easy to crowd them, and the yield in terms of weight may be much the same, but bigger garlic are a lot more fun and much easier to use in the kitchen. Sunlight. Whilst garlic can tolerate low sun during the winter months it needs 8 hours direct sunlight during the early and late growth stages. So lots of clear sky when it's maturing, September onwards. If your nutrition is right, (and soil acidity is right) then water could be the problem. While not much water is needed in winter, the ground should be kept moist through the season, especially in spring. A shallow watering is best the roots don't go down more than 30 cm max. Once to twice week during the maturing season. We cant control the weather, but avoid flooding (and applications of nutirients) during the final few weeks to lessen the chance of fungus attacks and sprouting. Garlic likes a moderate amount of lime (dolomite), you can rely on the recommended amount at least two weeks before planting and once every three years. Maturity. Look for tops fading in colour, a weakening of the stem near the base and a flattening of the top of the bulb when (gently) exposed Thats a lot and there's a lot more. It's a labour of love and a lifetime. And I'm sure others will have other suggestions, this is just a framework of what has worked for me. Planting at the moment actually. Regarding shallots most of the above also applies but Im not much of an authority. Shorter season length, but most of the above applies. I plant under the same conditions as garlic but only a few dozen and get good results.
