How to Grow Garlic

There are a few things you need to know before you plant garlic. First, it likes full sun. Second, it doesn’t do well in saturated soil, so make sure the soil is well-drained.

Below are other growing requirements.

Fertilizer Requirements

When it comes to feeding your garlic plants, you want to offer them a moderate-to-high-nitrogen fertilizer [1]. A balanced fertilizer should also work great, providing your plants with good nutrition.

You can spread manure or compost around the base of the plant every couple of weeks throughout the growing season. If possible, use aged manure or compost.


When it comes to watering your garlic, you want to make sure you’re doing it evenly. Don’t overwater, but also don’t let the soil dry out completely between waterings.

A good rule of thumb is to give your garlic about an inch of water per week, either from rain or from a garden hose.

If it’s particularly hot outside, you may need to water your garlic more frequently. If the weather has been cloudy or cool, then less frequent watering should suffice.

Just make sure that the soil remains moist but not saturated. Don’t allow too much water in the planting area, as this can be detrimental to your garlic’s health and growth.

Garden Pests

Some common plant pests that affect garlic include thrips, bulb mites, and leaf miners. There are also bad nematodes, leek moth larvae, onion maggots, and red spider mites.

However, there are a number of organic treatments that can repel or kill these pests. Make sure to practice regular crop rotation in your garden to reduce nematode populations.

You can also use companion planting strategies like placing garlic close to marigolds or even nasturtiums. These plants naturally repel pests.

Plant Diseases

Some plant diseases that affect garlic include basal rot, damping off, downy mildew, bacterial soft rot, and purple botch.

Fortunately, there are ways you can minimize risks. For instance, practice crop rotation and avoid overwatering.

Furthermore, provide adequate space between your plants to allow for good air circulation. Lastly, make sure to engage in proper sanitation habits, like cleaning up garlic plant debris.

How to Harvest

Harvesting garlic is pretty easy and straightforward.

You’ll want to wait until the bottom leaves begin to dry up, and then you can gently dig them up with a garden fork or spade.

Once dug up, gently brush off as much soil as you can and leave the bulbs to dry out in a spot with plenty of air circulation.

How to Store Garlic

Now that you know which plants to pair with your garlic and how to grow it, let’s talk about how to store it.

The best way to store garlic is in a cool, dry place out of direct sunlight. You should also make sure that the environment is well-ventilated, as this will help ensure that your garlic doesn’t become moldy or mildewed.

If you’re looking for a quick and easy storage solution, you can store them in mesh bags or other breathable containers. This should be placed on the kitchen counter in a basket or pantry since these areas tend to have the perfect temperature and humidity for storing garlic.

You should also pay attention to how long you’re storing it. Freshly picked cloves of garlic will last longer than those that have been sitting around for a while.


When it comes to choosing neighbors for garlic, some plants are great for boosting its production and pest resistance, while others can have a negative impact. By knowing which plants to pair with garlic, you can help it reach its full potential in your garden.
