Growing potatoes in wood chips is an innovative technique that offers several potential benefits. Wood chips provide drainage suppress weeds, and add organic matter to the soil as they break down. Follow this guide for tips on using wood chips to grow potatoes successfully.
Overview of Growing Potatoes in Wood Chips
The basic steps for growing potatoes in wood chips are
-
Select a site with full sun exposure and well-drained soil.
-
Spread a 6 to 8 inch layer of wood chips over the site. Hardwood chips like oak or maple work best.
-
Cut seed potatoes into smaller pieces, ensuring each piece has at least one sprout.
-
Plant the potato pieces shallowly in the wood chips, spacing 12 to 18 inches apart.
-
Cover potatoes with a thin layer of additional wood chips.
-
Water thoroughly after planting and regularly throughout the growing season.
-
Add more wood chips as mulch as plants grow to retain moisture and suppress weeds.
-
Harvest potatoes when vines start to yellow and die back by gently digging in the wood chips.
Advantages of Using Wood Chips
There are several potential benefits to using wood chips for growing potatoes:
-
Excellent drainage – Wood chips prevent soggy soil and promote healthy tuber development.
-
Nutrient release – As wood chips break down, they provide organic matter and free nutrients to the soil.
-
Weed suppression – The thick wood chip layer blocks light to prevent weed seeds from sprouting.
-
Soil aeration – Wood chips create air pockets in the soil for better oxygen circulation to the roots.
-
Temperature moderation – Wood chips insulate the soil and protect potatoes from extreme highs and lows.
Selecting and Preparing Wood Chips
For best results, use fresh hardwood chips without leaves or needles, free of diseased wood. Oak, maple, ash and other dense hardwoods are ideal. Avoid using wood chips from treated, painted or chemically contaminated wood sources.
Before planting, spread wood chips in the chosen site 6 to 8 inches deep. Rake and smooth out the layer of chips. If the soil is compacted, loosen it slightly before applying wood chips.
Planting Potatoes in the Wood Chips
Be sure to use certified disease-free seed potatoes. Cut potatoes into smaller pieces, making sure each piece has at least one good “eye” or sprout. Plant the potato pieces shallowly in the wood chips, spacing them 12 to 18 inches apart. Place them just deep enough to keep pieces stable and upright.
Cover planted potatoes with just a thin layer of additional wood chips, about 1 to 2 inches. This protects sprouts while still allowing them to emerge. Water the potatoes well after planting.
Ongoing Care and Hilling
Potatoes require consistent moisture, so check soil frequently and water when the top few inches of wood chips are dry. Avoid overwatering, which can lead to tuber rot.
As plants grow, hill more wood chips around them, burying about two-thirds of the stems. This hilling provides more space for tubers to expand and protects them from sunlight exposure. Add 4 to 6 inches of wood chip mulch at a time.
Harvesting Potatoes from Wood Chips
Harvest potatoes once the vines start yellowing and dying back, indicating tubers are mature. Dig carefully through the wood chips with a garden fork to lift out the potatoes while minimizing damage. Cure harvested potatoes by storing at 60-70°F for 1-2 weeks. Store cured potatoes in a cool, dark location for several months.
Tips for Success with Wood Chip Potatoes
-
Use fresh, disease-free seed potatoes each season for best results.
-
Ensure potatoes receive consistent moisture, especially during tuber formation.
-
Avoid over-fertilization, which can reduce yields.
-
Control pests like potato beetles by handpicking or using organic methods.
-
Rotate potato growing sites each year to prevent disease buildup in the soil.
-
Cure and store potatoes properly after harvest to maximize storage life.
Growing potatoes in wood chips offers an innovative way to cultivate tubers while improving the soil and reducing maintenance. Follow the tips in this guide for site preparation, planting, care, and harvesting to get a bountiful wood chip potato crop. Monitor soil fertility and plants closely when trying this method for the first time. With practice, you can enjoy thriving potato harvests grown sustainably in wood chips.

FAQ
Do potatoes grow in wood chips?
What grows well in wood chips?
How long does it take for wood chips to turn into soil?
Can you grow potatoes in pine shavings?
How do you grow potatoes in a raised bed?
Potatoes growing in 2ft deep raised beds, surrounded by wood chip mulched paths. We then fill the remaining bed up with a mix of compost and the topsoil that was on the paths around the beds. The paths are then backfilled with wood chips to prevent mud and keep down weeds. Over time, the wood chips in the path slowly decompose from the bottom up.
Should I mulch my Potatoes?
If you mulch most of your beds with wood chips, straw, or leaves, you’ll want to mulch your potatoes too. If you have access to large quantities of compost or aged animal manure, you may want to go the “Charles Dowding” route and cover the topsoil of your beds with compost. Growing potatoes in compost-amended beds looks like growing any other crop.
How do you grow no-dig potatoes?
The second, and possibly more popular method of growing no-dig potatoes is covering them up with a generous layer of mulch. You might not have heaps of compost readily available, in which case, use what’s on hand: These are all excellent choices to serve as a medium for growing no-dig potatoes.
Can you use woodchips in a garden?
Mulching with woodchips is just one of the ways to use them in the garden, but it’s perhaps easiest. The benefits of woodchip mulch, especially for perennials, are enormous: Weed Control – If applied in thick layers, around 2-3 inches deep, wood chips can effectively eliminate the need for weeding a garden.
