Many vegetables require soil pH levels between 7 and 8, making home testing kits or visits to your state Cooperative Extension office an invaluable way of determining your garden’s current soil pH level.
Lime powder should be mixed into acidic soil before planting any vegetable plants. Ideally, this step should take place several hours prior to transplanting any seeds or transplanting vegetables from seedling to pot.
Fall
Garden lime is an integral component of any vegetable garden, particularly those growing acidic soil. Garden lime helps rebalance its pH level so it becomes slightly alkaline instead of acidic, providing more favorable conditions for many vegetables as well as helping prevent diseases associated with acidic soil conditions. But to maximize its effectiveness it must be applied correctly at just the right time and in just the right manner.
Fall is the ideal time of year to add garden lime, as this gives the soil time to adjust its pH after reacting with it and absorb it, ready for spring planting. Furthermore, garden lime should always be applied prior to applying high-nitrogen fertilizers which may react adversely with it and reduce their effectiveness.
Utilizing a soil test kit, determine the natural pH balance of your garden soil. Below 7 pH is considered acidic and additional garden lime is required for acidity; while over 7 is considered neutral and no additional fertilizers should be required.
Purchase a soil testing kit online or from any home and garden store and follow its directions for taking samples of garden soil to send off for analysis in a laboratory. When you receive your results, you will know whether any amendment is needed – as well as in what amounts.
There are certain vegetables that prefer acidic soil conditions, like potatoes and sweet potatoes. Meanwhile, other species prefer slightly alkaline conditions like tomatoes, peppers and brassica family members like cabbage cauliflower kale that thrive best with garden lime treatments. These are examples of plants which would most benefit from being planted around your garden.
Garden lime comes in several forms. Quicklime is solid limestone that can be purchased and applied using either a garden sprayer or hand-held spreader; before planting the seeds it must be worked into the soil with care. Garden lime also comes in pellet form that can be broadcast and raked into place.
After applying garden lime, water it to activate its chemical reaction that changes soil’s pH level. Soaker hoses or watering cans work best as these allow the lime to slowly soak into the soil over time. Once completed, allow for at least three weeks before sowing new seeds.
As soon as garden lime has been applied to soil, it should not be tilled over immediately as this can cause it to be scattered and washed away by rain or wind. Spread it out evenly by scattering in rows along a row rather than blanketing an area, to ensure all areas of soil receive equal amendment.
Spring
Vegetables generally do well in soil with a pH level between 5.8 and 6.3, so if your garden soil falls significantly below this mark, lime can help raise it gradually over time. It’s best to apply lime in advance of planting season – fall is ideal as cool temperatures and winter moisture allow pelletized lime to slowly dissipate into the ground before spring arrives.
As well as vegetables, gardens with legumes such as beans, peas and lentils can benefit from regular applications of garden lime. Legumes prefer slightly alkaline soil which helps them avoid clubroot disease; members of the brassica family (kale, broccoli and Brussels sprouts) also thrive best when grown in slightly acidic soil conditions.
Lime can be purchased at most garden centers. It comes in various forms, from agricultural limestone to dolomite; with dolomite being an especially effective plant food. Dolomite should be applied two to three months before planting for optimal results, although soil testing services offer this information for a nominal fee.
When applying garden lime to your vegetable garden, choose a day that is sunny and windless. Wear protective clothing such as gloves and a dust mask while mixing the lime into the soil – this should prevent it from becoming overly acidic; otherwise wait one year after applying manure before adding garden lime.
Gardeners utilize various soil supplements to prepare their soil for gardening, including fertilizers, compost and garden lime. Regular pH tests should be performed and adjusted as necessary; gardeners must also be aware that certain plants don’t respond well to garden lime applications – in particular areas with Rhododendrons, Azaleas or Magnolias growing nearby should avoid using garden lime in this regard.
As well as maintaining an optimal soil pH level, other important considerations when cultivating vegetables and flowers in your garden include selecting an ideal location, purchasing fresh seeds or transplants, and having adequate water access. It is wise to create a checklist of all these tasks before planting your crops so as to remain on track and ensure all requirements for successful harvesting have been fulfilled. Spring soil testing is another good practice.
Summer
If you need to add garden lime during the summer, apply it on a cool or mild day when weather is not too hot or windy. Spread it across the soil surface then work it in with either a spade or rototiller before applying any more lime. Be wary of over-liming as too much lime can make the soil too alkaline; overly-alkaline soil prevents plants from taking in essential nutrients that they require for healthy growth, leading them to either stunt or die.
Soil needs time to absorb and adjust to any additional nutrients present before planting can begin. Gradual addition of lime helps give this time, as it provides the soil time to adjust as well. Eventually it may neutralize any excess nutrients.
Vegetables require a certain level of acidity in their soil for healthy growth, yet commercial fertilizers often exceed this threshold and exacerbate soil acidification beyond what’s necessary. Gardeners should conduct soil testing prior to applying any type of fertilizer – including lime – and only add as needed for maximum soil health.
Fall is a perfect time for applying garden lime. Cool temperatures and snowmelt allow pelletized garden lime to seep into the soil without overly limeing it; then by spring gardening season rolls around, your soil is ready for vegetable plants to flourish!
Some gardeners enjoy applying a light application of lime in the spring as well; however, it’s important to remember that your soil may still be altering itself through summer and if this is done then retest your soil in fall so as to know whether or how much lime needs to be added the following year.
If you’re growing tomatoes in your garden, a small dose of lime may help prevent blossom end rot caused by calcium deficiency. A sure sign that more calcium should be present is the presence of dark spots on the ends of tomatoes; these could indicate the need for additional calcium in their soil.
Some gardeners favor dolomite lime for vegetable gardens as it helps balance soil pH. When applying dolomite lime, be careful not to apply too much as too much can suffocate and stunt plant growth. Also avoid applying manure at the same time; its nitrogen can react with the lime and keep it from being absorbed into the soil, instead put down your manure one year and lime the following – giving plants all of their necessary nutrients at once!
