There is no requirement at being a seasoned gardener or farmer to grow your very own garlic at home. It's also very achievable and easy to harvest your own good quality garlic with a little patience due to its long growing time and by just following a few steps and keeping track of the seasons.
Garlic is luckily easily grown in almost types of soil with a preferred pH of 6-7, but to grow larger sized garlic bulbs it's recommended that your soil is fertile and high in organic matter which can also be mixed in to the top layer of soil where you will be planting, also make sure you soil has good drainage or you will end up with rotted garlic.
Getting you Cloves
Sourcing your garlic is at the utmost importance as you don't want failed garlic after nine months of looking after them, hence why you will need to be patient with garlic. Avoid using garlic heads bought from the supermarket unless you can source certified organic bulbs or some from your local organic farmers market.
Once you have sourced heads your happy with, then start to break up your garlic head into cloves, as the cloves are what your will be planting. If everything goes well, every planted garlic clove will produce a lovely garlic head, fantastic!
Planting garlic is typically done in the autumn after the first frost sets in, so now is the perfect time to start preparing and selecting those garlic heads for planting in the next few weeks.
Just before planting and after you have separated your cloves soak the cloves in water for 10-12 hours, this makes sure you give your cloves the best start, try to also plan out planting area with a clove spaced every 10cm-15cm.
Ensure you plant the cloves standing upright, so the tip facing upwards, this is where the sprout will shoot. Bury each clove about 6cm-10cm deep and give them a good soaking with a fish emulsion, seaweed fertiliser or homemade worm tea. In colder climates mulching is critical to keep the garlic from freezing and it's also a great idea to keep those weeds at bay.
On Going Care
The cloves should sprout within a month from planting and the wait begins. Keep the newly planted cloves well hydrated in the warmer autumn months, watering every few days; expect for days with rain. Soils that are sandy may have to be watered more regularly to compensate for the faster water loss.
Feed the garlic with liquid seaweed fertiliser every month, and in midwinter, as the bulbs begin to form, apply a fertiliser high in phosphorous to help them swell and grow into lovely large bulbs.
Garlic is typically harvested in summer, but that can certainly change depending on where you are at in the country and warmer spring conditions. Reduce regular water into allow the bulbs to mature in the ground, checking their progress by digging with your fingers along the stem. The key indicator to know when the garlic is ready to harvest is the colour of the leaves, which will turn yellow and tanned when ready.
To harvest, loosen the soil surrounding the garlic without damaging the garlic heads and gently pull on the foliage. You can always select one as a test and determine by looking at it if the head and inspecting for well-developed cloves.
Once harvested hang your garlic in a cool, dry place. This not only helps the garlic keep for many months but you will also have access to new cloves to be planted once again in autumn.
