Fall is the best season to apply lime to color hydrangeas pink. The lime must be incorporated into the soil and must be moist for the soil to react with the lime. First, sprinkle lime around the hydrangea’s base and work it into the ground with a rake. After washing off any lime that accidentally landed on the foliage with the hose to avoid burns, water the hydrangea slowly and deeply to activate the lime.
Third, get ready to have patience. The hydrangea’s surrounding soil will not instantly change color with the addition of lime. It can take months or perhaps three years, depending on the condition of the soil. Check the pH of the soil twice a year. The hydrangea won’t be able to absorb iron if it rises beyond 6.4, and it could get chlorotic. When fertilizing in the spring, add an iron supplement if the foliage becomes yellow.
If soil testing for a pink hydrangea reveal a high quantity of aluminum, fertilizer with a high middle number, such 10-25-10, should be used. This middle number stands for phosphorus, which aids in preventing aluminum absorption, which causes hydrangea blossoms to turn blue.
If you decide to force your hydrangeas to turn pink, keep in mind that it will take time. Your hydrangeas will likely turn blue again if you cease monitoring the pH level and the alkaline begins to decline.
How much lime should be used to surround hydrangeas?
Large, deep green foliage and dense clusters of flowers with colors ranging from pink, blue, and white to red and purple are produced by hydrangea shrubs. The type of soil and its pH have a significant impact on the color of the bloom. To create pink or crimson hydrangea blossoms, apply lime to your soil in the early spring or late fall. Although it might be easier to apply lime to hydrangeas in pots, you can also integrate it into your garden soil to grow a bed of lovely pink French hydrangeas.
Dig a 6-inch-deep hole in the planting location, then remove some dirt. You may either test the soil yourself using a soil test kit or put it in a plastic zipper bag and mail it to your neighborhood garden supply store to have its pH value determined. Pink hydrangeas do best when the pH level is between 6.5 and 7.0. Lime will be added to the soil to raise the pH.

Visit your neighborhood garden supply store to get lime. For every 100 square feet of ground, you should typically apply 2.5 to 5 pounds of lime, or 3 to 4 tablespoons for two to three medium-sized hydrangeas.
At soil level, sprinkle lime all around each hydrangea plant. Don’t sprinkle it on the plants’ foliage. Alternately, mix 1 gallon of water with 1 tbsp of hydrated lime and spread it over the base of the hydrangea bushes.

To make sure the lime reaches the soil’s roots, rake the area. Alternately, turn the soil over and shovel it in. When doing this, take care not to damage or disturb the roots. Mulch made of cedar should be placed over the soil.
Dig a hole the size of the root ball for each of your hydrangea plants before placing them in the ground. Each plant’s surrounding soil should be tamped down and watered until it is moist. Lime will be absorbed by the roots, resulting in pink blossoms on the plant.

Put time-breaking lime pellets in the soil. Every year, in the early spring or fall, add lime to the soil. This allows the lime to combine with the soil and break down before the growing season. Use only the amount that is specified. The plant may suffer damage or perhaps die if you overdo it. After adding lime, fertilize the soil a few weeks or even a few months later. The chemical composition of the soil is altered when lime is added. Verify that your hydrangeas don’t share space with plants that need acidic soil.
Lime: Does it turn hydrangeas pink or blue?
How many of you can recall the argument between the fairy godmothers in Walt Disney’s Sleeping Beauty about the color of the princess’ ballgown? Every time the traditional mophead hydrangeas (Hydrangea macrophylla) bloom in June, I recall that scene. The colors are the stuff of enchantment because they are so vibrant.
Aluminum, not a fairy godmother, controls the color of this hydrangea’s blossoms, whether they are pink or blue. Lack of metal results in pink blossoms, whereas an abundance of aluminum results in blue flowers.
For pink blooms, add lime to the soil; for blue blooms, add aluminum sulfate. The soil composition determines the required amount of lime or aluminum sulfate.
If you are adamant that your hydrangea will be pink or blue, plant it in a container where the pH of the soil may be easily controlled.
Lime—does it benefit hydrangeas?
Although soil enhancements like garden lime can alter the color of hydrangea flowers, they don’t provide the plants with all the nutrients they require to thrive. Early in the spring, as soon as the leaves start to develop, is when hydrangeas benefit from fertilization. After the initial flush of flowers, fertilizer should be added once more around midsummer to encourage plants to produce another set of flowers if you are growing a reblooming variety like those from the Endless Summer series. Just remember to stop feeding your hydrangeas after July because doing so could encourage vulnerable new growth that is more susceptible to frost damage. To provide your plants with a consistent supply of nutrients throughout the growth season, use a slow-release, all-purpose fertilizer ($22, The Home Depot).
How do I get more blooms on my hydrangeas?
Early spring or mid-July through late summer are the blooming seasons for hydrangeas. The methods for extending hydrangea blossoms’ life and producing more of them are discussed below.
Plant the hydrangea where it will receive morning light and afternoon shade, keep the soil continuously moist, and treat it in the spring with a fertilizer that is well-balanced to encourage more flowers. To encourage more blossoms, don’t prune your hydrangea too frequently. Hydrangeas bloom on the growth from the previous year.

Adding lime after planting is possible.
The conclusion of the fall growing season is the ideal time to apply lime to your garden soil, according to seasoned gardeners. This will provide the soil enough time to absorb the lime and regulate the pH. The lime must penetrate the soil for a number of weeks. The pH level of the soil at the time and the type of soil both play a role. Lime should be added right away following your most recent harvest.
Adding Lime in the Spring
You’re not required to add lime solely throughout the autumn. You can wait until spring to add lime to your garden soil. But you should do this well in advance of when you want to plant your garden. The better the lime nutrients are incorporated into the soil, the more lead time you have.
What is the shelf life of lime in soil?
An 8-mesh sieve should catch almost all of the lime, while a 60-mesh sieve should catch half of it. The apertures of an 8-mesh sieve are about 1/8 inch wide. Lime particles with a fineness greater than 60 mesh react more quickly than those with a coarser size (between 8 and 60 mesh). Remaining neutralizing power is provided by the larger lime particles.
What is calcic limestone?
A naturally existing rock largely made of calcium carbonate is called calcic limestone. It is also known as calcitic limestone or high calcium limestone. It typically has 90 to 95 percent calcium carbonate and fewer than 5 percent magnesium carbonate.
How much magnesium does dolomitic limestone contain?
The magnesium carbonate content of dolomitic limestone sold in Michigan ranges from 15 to 45 percent by weight, with the remaining 85 to 55 percent primarily composed of calcium carbonate. A material analysis is necessary to ascertain the precise response. Magnesium is often expressed as a percentage of magnesium carbonate in the limestone analysis report. Add 0.29 to the percent magnesium carbonate to get the elemental form. For instance, a ton of dolomitic limestone with a magnesium carbonate content of 30% has 174 pounds of elemental magnesium (0.30 times 2,000 times 0.29). In order to convert tons to pounds, multiply by 2,000.
When should I use dolomitic lime?
When a soil test shows that the magnesium content is low to marginal, use dolomitic lime. Use either calcitic or dolomitic lime when the magnesium content of the soil is sufficient. There is no proof that dolomitic lime is detrimental in any way.
What is pelletized lime?
Very fine calcitic or dolomitic limestone converted into pellets with a soluble binder makes up pelletized lime. The efficiency of pelletized lime is nothing exceptional. It neutralizes soil acidity in the same way as conventional agricultural lime chemically speaking. To obtain the same result, the rate must be the same as for agricultural lime.
What are the materials called fluid lime, liquid lime or lime suspension?
Limestone that has been finely ground is suspended in water or a nitrogen fertilizer solution. Typically, the suspension contains 25 to 40 percent water, 55 to 70 percent fine limestone (finer than 100 mesh), and 1 to 4 percent colloidal clay.
Are liquid lime materials better than dry lime?
No and yes. These liming substances respond swiftly and boost the pH of the soil quickly, but their long-term effects on pH maintenance are minimal. The fact that less lime may often be applied overall than with dry limestone may be a negative. As a result, lime treatments must be made more frequently. Additionally, these items frequently cost more than dried agricultural lime.
Are wood ashes good for liming?
Yes. First, check the pH of the soil. Do not add wood ashes to soil with a pH of 6.5 or higher. Apply up to a twofold increase in lime every three years when necessary. Limit the application of wood ashes to six tons during a three-year period, for instance, if the required amount of lime is three tons per acre. This translates to 275 pounds of ashes per 1,000 square feet on a garden. Before adding additional, check the pH.
What are the benefits of using lime?
By a) increasing soil pH, b) enhancing nutrient availability generally, c) lowering soluble aluminum, and d) enhancing microbial activity, liming acidic soils improves crop yields. Aluminum and manganese are toxic to plants when present in excess because they prevent root cell proliferation and stunt growth. Aluminum-toxic plants could also be deficient in calcium or magnesium. Maintaining proper soil pH maximizes the availability of several plant nutrients. Fertilizer application effectiveness is increased by proper liming.
Will liming pay?
Yes. Where necessary, each dollar invested in lime will yield a return of $5 to $10. In mineral soils, increasing the pH from 5.7 to 6.5 may increase alfalfa yield by at least 35% and corn or soybean yields by at least 20%.
How much lime should I apply?
The quantity of lime required can be determined via a soil test. The pH of the soil cannot be used to determine how much lime is needed. To calculate the required amount of lime, the majority of soil testing facilities employ a unique buffer pH approach. The SMP buffer technique is employed at Michigan State University.
How long will it take for lime to react with the soil and how long will it last?
Although benefits from lime may be seen during the first few months of application, lime will totally react with the soil in two to three years. The kind of lime used, the total acidity of the soil, the amount of organic matter, the type and amount of clay, the cropping and management techniques used will all affect how long the effects of lime last. Three to four years after applying lime, a soil test will assist reveal the solution.
What if my leased land needs lime?
Applying lime to land that may or may not be used for crop production the following year makes farmers reluctant. Farmers must understand the advantage in crop productivity they can experience during the application year, and landowners must understand that lime preserves the condition of their soil. When lime is required on rented land, a farmer must either ask the landowner to share the expense of the lime, prorated over a four-year period, or seek a multi-year lease to ensure the return on his or her investment.
Should I lime my soil to pH 6.0, 6.5 or 6.8?
Liming to pH 6.5 is advised for most crops. Liming to a pH of 6.8 is crucial while growing alfalfa. Liming to a pH of 6.0 is sufficient for low-maintenance grass graze, vegetables, and potatoes. Certain crops, like blueberries, that thrive in acidic soil don’t typically benefit from liming. Lime is used for the crop that is most sensitive to pH when multiple crops are grown in succession.
Will fertilizer replace the need for lime?
No, soluble aluminum and manganese concentrations significantly rise when soil pH falls below 5.5. Plants can acquire lethal levels of these two elements in extremely acidic environments. Regular liming lowers the risk of producing an acid subsoil, boosts the effectiveness of fertilizer applied, and results in higher crop yields because many fertilizers are acid generating.
Should I topdress lime on my established lawn?
If the soil’s pH is below 5.5 in the top 3 inches of the soil, topdress with 25 to 50 pounds of lime per 1,000 square feet. Test the soil before creating a lawn, then add fertilizer at the suggested dosage and stir it in.
