Best Top Soil

Declaring any topsoil the absolute “best” would be misleading as their value truly depends on your specific needs and what you prioritize. For example, the best top soil when growing blueberries is very acidic while a plant like lavender grows well in alkaline soil.

It may sound confusing, but the topsoil recommendations below are broken down by plant type to make it easy for you.

Best Acidic Topsoil

I don’t recommend buying acidic topsoil by the bag. It would be expensive and unnecessary. Instead, simply amend your current topsoil with an organic acidifier. Here are a few of the best products to make your top soil acidic.

  • Epsoma Organic (Check Price on Amazon): Use Espoma Organic Soil Acidifier for azaleas, hydrangeas, rhododendrons, blueberries, evergreens, strawberries, camellias, and all plants that thrive in acidic soils
  • DTE 4-3-6 Acid Mix (Check Price on Amazon): Natural fertilizer blended especially for acid lovers. Encourages lush flowers and fruit, apply Acid Mix in early spring for vegetative growth and again when blooms appear.
  • True Organic Soil Acidifier (Check Price on Amazon):  Made With 100% Organic and Natural Ingredients: True Organic plant fertilizers exceed industry requirements for clean sourcing and testing for pathogens and are pet friendly.

Here is a list of popular garden and houseplants that prefer acidic topsoil:

Fruits and Vegetables Preferring Acidic Top Soil

  • Blueberries: These delicious berries crave acidic soil and respond poorly to neutral or alkaline conditions.
  • Cranberries: Like blueberries, cranberries require acidic soil for optimal growth and fruit production.
  • Strawberries: While they tolerate a wider range, strawberries tend to produce sweeter and larger fruits in slightly acidic conditions.
  • Rhubarb: This tart-tasting fruit thrives in acidic conditions and often struggles in highly alkaline soil.
  • Potatoes: Although adaptable, potatoes generally prefer slightly acidic conditions for optimal growth and quality.

Acidic Soil Flowers

  • Rhododendrons and Azaleas: These popular blooming shrubs require acidic soil for vibrant flower displays and healthy foliage.
  • Hydrangeas: The blue flower color of hydrangeas is closely linked to acidic soil, while higher pH levels can produce pink or purple blooms.
  • Camellias: These elegant evergreen shrubs also favor acidic soil and produce stunning flowers from late winter to spring.
  • Hollyhocks: These tall and majestic flowering plants thrive in acidic conditions and add a touch of whimsy to garden borders.
  • Dogwood trees: The delicate white and pink blossoms of dogwood trees prefer acidic conditions, particularly the Kousa dogwood variety.

Other Plants Preferring Acidic Topsoil:

  • Ferns: Many fern species flourish in acidic soil, creating lush and textured groundcovers in shady areas.
  • Evergreens: Certain evergreen shrubs and trees, like hollies and pines, often prefer acidic soil and thrive in areas with naturally acidic environments.
  • Mosses and lichens: These low-growing plants contribute to healthy ecosystems and often indicate the presence of naturally acidic soil.

Best Neutral Ph Topsoil

Just about every bag of topsoil you find will be neutral ph, but a well balanced slow release fertilizer is not included with the cheap bags of dirt labeled as top soil.

Determining which is the best fit for your garden comes down to the fruits and vegetables you are planting. Generally, most garden vegetables prefer a well balanced NPK ratio from the fertilizer you use with the topsoil.

Best Neutral Growing Medium

  • Wonder Soil Coco Coir (Check Price on Amazon): These compressed coco coir bricks from Amazon are perfect for homebodies that prefer to spend their time in the garden rather than the local nursery. Coco Coir is a completely neutral growing medium with great drainage. It also allows your plants to grow a robust root structure.

Best Neutral Fertilizer

  • CalMag Pro Nutrient Fertilizer (Check Price on Amazon): Contains Guaranteed minimum 10% Calcium (Ca) and 3% Magnesium (Mg) in the optimum ratio for plants. Also has Potassium and other elements to facilitate uptake and benefit your plants. Highly absorbable and fully water soluble forms of Calcium, Magnesium and Potassium. The 3lb size makes 700+ gallons due to the concentrated dry form. In other words, CalMag Pro requires mixing/diluting. Keep that in mind if you are looking for a fertilizer that is ready to use out of the box.

Fruits and Vegetables Preferring Neutral Top Soil

  • Apples: These crunchy kings prefer neutral turf for bountiful harvests.
  • Melons: Watermelon, cantaloupe, and honeydew crave neutral ground for sweet, juicy rewards.
  • Peas, Asparagus, Tomatoes, Etc: The truth is, the majority of vegetables prefer neutral soil. Even those that have a preference to acid/alkaline will typically still grow in neutral soil.

Neutral Top Soil Flowers

  • Zinnias: These vibrant and cheerful annuals come in a dazzling array of colors and bloom profusely through summer. They’re low-maintenance, attract pollinators, and tolerate a range of conditions, making them a true garden favorite.
  • Marigolds: These bright and bold annuals not only boast stunning shades of orange, yellow, and red, but they also act as natural pest deterrents, protecting your garden from unwanted critters. They thrive in full sun and well-drained neutral soil.
  • Cosmos: These delicate and airy annuals offer a soft touch with their daisy-like flowers in shades of pink, white, and purple. They attract butterflies and bees, thrive in full sun, and readily adapt to neutral soil conditions.

Best Alkaline Topsoil
