Usually, acidic soils have a pH range of 6.0 and below, and they are naturally found in areas with high rainfall. While a few vegetables do perfectly in neutral or alkaline soils, there are also many that can adapt and thrive in acidic conditions.
If your garden has acidic soil, you can still grow some vegetables known to do well in such soil. Here are a few of them.
Potatoes

The presence of acidity acts as a guard for potatoes from fungal diseases, such as scabs, triggering the formation of lesions. Potatoes need well-drained soil; they benefit from acidic soils due to their organic complexes that promote better drainage. Well-drained soil minimizes waterlogging and keeps the roots healthy.
Carrots

Carrots get their sweet flavor and tender texture from acidic conditions. The pH of the soil is also very important for carrot growth, as carrot plants benefit from well-drained soils. Also, under acidic conditions, root diseases are less likely to occur in carrots.
Blueberries

Blueberries thrive in acidic soils. They do well in cool, high rainfall conditions, which makes them a great choice for naturally acidic soil regions. Additionally, the low pH helps blueberries take up essential micronutrients such as iron, magnesium, and manganese from the soil more readily.
Radishes

Quick-growing root vegetables, radishes, will tolerate a wide range of soil conditions. Some varieties perform well in more acidic soils. They like well-drained soils and do well in high pH. Radish plants help to neutralize the acidity in a covering of soil, and it is then beneficial for other plants.
Peppers

Pepper plants are very heat-tolerant, and they do grow well in full shade and require good drainage. They also thrive in slightly acidic soils. Peppers require lots of sun and warmth for the peppers to form well.
Tomatoes

Tomatoes thrive in acidic soil with a pH as low as 5.5, as an article on bestjuicytomatoes.com attests. Tomato plants are not particularly fussy about soil, and they do well in acidic conditions, which helps to avoid some diseases and promotes good fruit sets. However, do make sure you give them good drainage and full sun.
Lettuce

The lettuce thrives in soil with a slightly acidic pH. The key to sowing this cool-season vegetable is to keep its soil moist, especially if you grow it during summer, which is off-season! Lettuce will grow leaves that are tender and full of flavor when growing in acidic soil. On the same note, because of its low pH, it repels bugs and fungi, which often attack lettuce plants.
Garlic

According to EOS Data Analytics, Garlic prefers slightly acidic soil in the pH range of 6.0 to 6.5. They grow best in well-drained soil with moderate water retention. The acidic soil helps prevent the scourge of white rot, a fast-moving disease in neutral or more alkaline soils.
Onions

Originating in Europe, onions are a common and versatile vegetable that thrives in acidic soils. They do well in sandy loam or loamy, well-drained soils, as they do not like waterlogged soils. The lower acidity levels also encourage good root structure and ensure that fungal diseases are less likely to develop.
Spinach

Another nutritious leafy green that sure packs a lot of beneficial rewards is Spinach. It grows quite fast; for each season, there can be many harvests. Spinach loves acidity in the soil and absorbs all its essential nutrients through acid.
Cabbage

Cabbages are hardy vegetables that will grow in soils that are too acidic for many other crops. It does best in well-drained, slightly acidic soil for optimum growth. A reduced pH level reduces the number of diseases attacking cabbage plants -for example, clubroot and blackleg.
Broccoli

According to PlantVillage, broccoli needs slightly acidic soil with a pH of 6.0-7.0. It is an easy-to-grow, fast-growing vegetable packed with nutrients that appreciates moist but well-draining soils. Highly acidic conditions help cut down the incidence of pests and diseases.
Rhubarb

Rhubarb is a perennial vegetable that likes well-drained, fertile soil and can tolerate cold temperatures. Rhubarb will handle a little more acidic soil conditions than the other veggies, and once it gets going, it can produce for numerous years.
Parsnips

Parsnips are root veggies that want slightly acidic soil, with a perfect pH of around 5.5 to 7.0. And since they need a long growing season, most appreciate the well-drained but loose soil that acidic land provides. These vegetables stand up well through all the cold weather and become even sweeter following a frost.
Cucumbers

Cucumbers like slightly acidic soil. These heat-loving plants need full sun and water, and they do well in the nutrient-rich, acid soil that drains well, too. It is much easier to grow healthy cucumbers on acidic soil, as the soil helps to ward off pests and diseases.
