How To Raise Soil Ph – Most ornamental and edible plants prefer relatively neutral soil, but some gardens may be naturally acidic, or the soil may become acidic due to other factors. Fertilizers and new manures, as well as environmental problems such as acid rain, can cause soil pH to drop.
Some soils are naturally acidic, and some soils can become more acidic over time due to changes and environmental factors.
How To Raise Soil Ph
By definition, a neutral soil pH is between 6.6 and 7.3. Acid soils have a pH below this range, while alkaline soils have a pH above this range.
Understanding Ph And How It Affects Cannabis Plants
Depending on the plants you want to grow, you may need to adjust the pH of your soil before planting. Correct pH levels are important to plant health because they affect the plant’s ability to properly absorb nutrients. In this guide, we will teach you how to create alkaline soil by naturally increasing the pH.
Natural products and amendments can help “sweeten” garden soil (make it less acidic and alkaline).
When your plants aren’t blooming, it’s time to test your soil for nutrients and pH. If your soil test indicates that you need to increase the pH of your soil, here are some methods you can use.
Compost is (or should be) neutral, so it can dilute the acidity of the soil and bring it back into balance.

Compost is an amazing soil additive that can make a huge contribution to your garden space. It is also one of the best ways to balance soil pH problems.
Compost and old manure have a neutral pH. Adding it to garden beds can gradually adjust the pH of the soil over time, which is best for your plants and garden. Although this method takes longer to raise soil pH than other treatments, it is natural and can improve the health of your garden.
Compost not only adjusts pH but also improves soil structure. Compost can help loosen compacted clay and help sandy and loamy soils better retain water and nutrients. Compost also provides plants with many nutrients to support their health and growth.
To use compost in the garden, add about 2 inches of compost to the bed and spread it over the top 6 inches of soil.
Liquid Lime For Lawn & Garden
Whether you buy bagged compost online or at a garden center, for a more affordable solution, consider investing in a home compost bin and making your own. The more you use your home composter, the more it will reduce your costs and pay for itself.
Lime is a very popular soil additive made from ground limestone or shale and used to “sweeten” or condition the soil. Lime is easy to use, readily available at most garden centers, and is very effective at raising soil pH. That said, it’s best to apply lime sooner rather than later, as it can take a year or more to improve soil pH.
If you are growing an organic garden, you can use calcite lime or dolomite lime. Both types of lime work well, but orange dolomite also contains large amounts of magnesium, which your garden doesn’t need. If your garden soil is rich in magnesium, you should choose calcite lime.
Quicklime is also available for purchase, but this type of lime is not approved for use in an organic garden. It is also more reactive, can burn plant roots or skin during application, and can leak easily.
Wood Ashes For Garden Soil Primary And Micro Nutrients, Adjusting Ph
Lime gardens can be spread over the bed by hand and then spread with a rake. How many oranges you need depends on your garden, so follow the manufacturer’s instructions when using them. In general, 20 to 50 pounds of lime is needed per 1,000 square feet of garden in slightly acidic soil, but more lime may be needed if the soil is acidic.
People have been using wood ash in their gardens for generations, and it’s a great way to add nutrients to the bed and raise the pH of the soil. Using wood ash in this way also recycles the ash so that it does not become waste. This is especially useful if you have a wood stove or fireplace that you use regularly.
Wood chips don’t just change the pH of your soil. It also contains calcium and potassium, as well as small amounts of magnesium and phosphorus, which are great for increasing soil fertility. It also contains iron, zinc, boron and other nutrients that plants need.
However, not all wood chips are created equal and you want to avoid wood chips that come from treated or painted wood. Wood ash from pellet stoves is also not recommended for use in the garden, as it may contain polycyclic aromatic hydrocarbons (PAH) and other toxic compounds.
The Easiest And Most Reliable Way To Test Soil Ph
To sprinkle wood ash on your garden, use dry ash and spread 20 pounds (or 5 gallon buckets) of ash over the garden bed. This will create a dust layer 1/4 inch deep in a 1,000 square foot garden, which is enough to restore slightly acidic soil, but more layers may be needed if your garden is very acidic or has a larger planting area.
For a very simple solution, standard baking soda can be used to adjust soil pH in small garden beds and container gardens. Baking soda (also called sodium bicarbonate) is easy to find and inexpensive, especially if you buy it in bulk. It also raises the pH of the soil faster than lime, but does not stay in the soil as long and needs to be applied more often.
For a standard application, add one tablespoon of baking soda to one gallon of water and add to a garden sprayer. Apply this mixture to the soil every few months for best results.
Dried oyster shells can be purchased at chicken feed stores, garden centers, and online.

Crushed oyster shells, oyster shells, and eggshells contain calcium carbonate, which can raise soil pH. You can collect these things and crush them yourself, or you can buy pre-shredded peels in bulk or from most garden supply centers.
Although these materials are easy to use and effective, they contain high levels of calcium that can disrupt the magnesium-calcium balance in the soil. To avoid this, test your soil before deciding whether oyster shells are suitable for your garden. You can also combine oyster shells with magnesium-rich Epsom salts to balance out the added calcium.
Once you’ve chosen a soil amendment that’s right for you, follow the manufacturer’s instructions and recommended rates for applying it to your garden. The soil is then modified to activate it.
After a few months, test the soil again to see how the amendments are working. Depending on the results and the amendments you choose, you may need to add more supplements to the soil to raise the pH. Also, remember that baking soda and wood ash work faster than lime and compost, but require frequent applications.

Additionally, since soil pH is affected by many factors, there are a few things to keep in mind if you want to keep your soil healthy.
First, it’s a good idea to test your soil every three years. This will help identify nutrient and pH problems before they cause real problems for your plants.
Second, consider adding compost or old manure to your garden. This will maintain soil health, work to neutralize pH, and replenish nutrients as plants use them.
Finally, you may want to use synthetic fertilizers instead of organic fertilizers or compost. Synthetic fertilizers, especially those containing ammonium sulfate, ammonium nitrate, and sulfur-coated urea, can lower soil pH and create an acidic environment, especially when over-applied. Natural fertilizers are generally better for plants and do not affect soil pH.
How To Make Your Garden Soil More Acidic: 5 Ways And What To Avoid
Hydrangeas are known for flower color changes that are influenced by soil pH. Acidic soil will produce blue flowers, alkaline soil will produce pink or even red flowers. If you want your hydrangea to be pink, raise the soil pH above 7.0.
Different plants have different needs, so the plants you want to grow will be affected by the pH of your soil. A good rule of thumb: most garden plants prefer a neutral pH between 6.5 and 7.0.
PH affects a plant’s ability to absorb nutrients. Unbalanced soil pH can cause nutrient deficiency symptoms such as yellowing of grass or leaves, stunted growth, visible leaf veins, and poor yield.
Yes, you can test the pH of your soil at home using a simple test kit or soil probe. However, for more accurate results, it is best to send a soil sample to your local cooperative extension office. They can’t give you definitive proof
