Frequently Asked Questions About Companion Plants For Garlic
Winter squash or pumpkins can be a good crop to plant after harvesting your garlic. Other crops are tomatoes, peppers, or bok choy. Just make sure not to plant onions or beans in the area where you harvested your garlic.
Onions and garlic can be planted together. Both are ready to harvest around the same time, and both repel plenty of unwanted pests and insects. Be careful though with planting all of your onions and garlic together, as onion maggots can travel easily from plant to plant. If you end up with an infestation of onion maggots and all of your onions and garlic are planted together this could result in a total loss of both crops.
Cucumbers do not do well with other crops that have a pungent smell. It is best to keep cucumbers and garlic in separate areas of your garden.
