Sure, it’s still late March. But it’s never too early be thinking about how you are going to get your garden plot ready as soon as planting season rolls around.
From getting a handle on what’s in your soil to additives like compost, Kate Garland, a horticulturist with the University of Maine Cooperative Extension Office, has some suggestions and steps to take before you put the first seeds into the ground.
Why you should get soil tested
Your plants spend their entire lives in the soil. For them to have the best chance possible, you need to know what’s in that soil before dropping in a single seed or seedling.
“Test your soil,” Garland said. “Whether you’re starting a new plot or getting ready to dig into an existing garden bed, it’s a good idea to test your soil every three to four years.”
Soil test kits are available from most farm and garden supply stores for the gardeners who feel confident to collect the samples, conduct the test and read the results on their own.
University Extension offices and many state soil conservation offices are a great resource with pre-packaged test kits. All you need to do is collect the samples and bring them to the local Extension office or soil conservation office who will take care of sending them to a laboratory for testing. There is often a fee associated with these services, but the results are reliable.
“The most important thing to keep in mind is that the report you get back is only as good as the sample you bring in,” Garland said. “Follow the instructions [on the test kit] and you’ll have some useful information.”
Probably the most useful information included in the soil test results is the pH levels in your garden soil. Simply put, the pH number measures the acidity of your soil. The lower that level, the more acidic the soil which can hamper a plant’s ability to properly absorb nutrients.
High pH — or too little acidity — can also create problems resulting in stunted and malnourished plants.
How do you change pH levels?
If soil were a fairytale character, it would be Goldilocks. Under ideal conditions it should not have too much or too little acidity. It should be just right at pH neutral.
To get the productive, pH neutral level, Garland said growers can use a variety of fertilizers or other soil amendments based on the pH levels shown in their soil test.
The best way to bring up the pH levels — or neutralize the soil — is with the addition of lime.
Commercial lime additives can be purchased, but gardeners can also use wood ash.
To lower the pH, additions to the soil of sphagnum peat, iron sulfate or organic mulches will bring up the acidity to those desired neutral levels.
“Don’t guess,” Garland said. “Adding too much of any soil amendment can have some significant downfalls [and] more is not better — staff in your local Extension office can help interpret soil report recommendations and are happy to discuss specific scenarios with homeowners and commercial farmers.”
Can you over-till?
Dedicated gardeners can’t wait to get into the dirt and start digging, and Garland understands that desire. But she also cautions against jumping the gun.
“Don’t dig too soon,” she said. “And avoid ‘recreational rototilling’ where you are working wet soil [and] tilling too frequently.”
This, Garland said, can lead to the soil breaking down and compacting. When soil is compacted, air, water and nutrients are blocked and unable to move through the soil to a plant’s roots.
Over-enthusiastic tilling also promotes weed growth.
“Weed seeds are often resting lower down in the soil profile,” Garland said. “When tilling occurs, those dormant seeds have a better chance of getting exposed to the proper conditions to germinate.”
Do you need walking space?
When planning what you will plant where in your garden, take some time to also plan establish walkways and stepping areas to avoid soil compaction from foot traffic.
“I personally like to establish wide planting beds with narrow walkways to maximize production space,” Garland said. “But I usually make [planting] beds narrow enough to also step across.”
What about compost?
Gardeners can never go wrong by adding compost to their soil. By combining organic matter like food scraps, garden waste, sawdust, straw or grass clippings in a bin or other container over time the natural process of decomposition breaks everything down into a nutrient-rich soil conditioner.
Known as “black gold” among gardeners, compost improves the quality of the soil’s structure and texture which helps it hold nutrients and moisture.
Compost also adds nutrients to the soil including nitrogen, phosphorus and potassium, the three most needed for healthy plant growth.
By starting to think about your garden now and formulating a plan for testing, boosting the soil and laying out the configuration you will be ready to jump in and plant this spring.
