Growing garlic is easier when the plants next to them help instead of compete. Companion planting is simply choosing neighbours on purpose. Some plants share the soil well, some attract helpful insects, and some keep pests busy elsewhere. This free planner gives you a clear list for garlic: good neighbours, plants to keep away, and flowers that help. You type in your row length and planting date, and it works out how many plants fit and when to expect a harvest.
Companion planting is not magic, and it does not replace good soil, water, and sun. Think of it as stacking small advantages. A taller neighbour can shade tender leaves in hot weather. A fast crop can use the space between slow rows before they fill out. A strong scent can confuse pests that hunt by smell. None of these effects is guaranteed on its own, but together they often mean healthier plants and less work for you in the garden.
The best companions for garlic in this planner are tomatoes, lettuce, beets, carrots, strawberries. These are plants that gardeners commonly grow beside garlic without trouble. Some use different soil depths, so their roots do not fight for the same layer. Others grow at a different speed, so they are picked before garlic needs the full space. Plant them in the same bed, but still leave the spacing this tool suggests, because crowded plants stay damp and invite disease.
Keep garlic away from peas, beans, cabbage in this plan. These combinations are best avoided because the plants may compete hard, share the same pests, or slow each other down. Keeping them apart does not mean you cannot grow them at all. It only means giving them their own bed or a different corner of the garden. If your garden is small, a path or a row of flowers between them is a simple buffer that often works well.
Flowers earn their place in a vegetable bed. For garlic, this planner suggests marigolds, calendula, nasturtiums. Flowers attract bees and other pollinators, and some attract hoverflies and ladybirds that eat aphids. Plant a few flowers at the ends of rows and in gaps, rather than in one separate flower bed far away. That way the helpful insects are already where your vegetables grow, and your garden looks far better while you work in it.
Spacing matters more than most new gardeners expect. This planner uses about 15 centimetres between garlic plants. Enter your row length in metres and the number of rows, and it tells you how many plants fit in each row and in total. Do not squeeze in extra plants to use up seedlings. Full-size plants need air around their leaves to dry after rain, and dry leaves mean fewer fungal problems through the season.
Timing is the second half of the plan. garlic usually needs about 180 to 240 days from planting to harvest, depending on weather and variety. Enter your planting date and the tool shows a harvest window, not a single promised day. If spring stays cold, expect the later end of the window. If summer is warm and you water well, expect the earlier end. Sow a small second batch two or three weeks later for a longer harvest.
Use the print button to take your list to the garden. A printed list is easier to follow outdoors than a phone screen in bright sun, and you can tick off rows as you plant them. Water garlic steadily rather than in big floods, feed lightly if the leaves look pale, and check under the leaves once a week for aphids or slugs. Small weekly checks catch problems early, when hand-picking or a strong spray of water is usually enough to fix them.
