Espoma Organic Garden-Tone
This is a good fit for gardeners who want a balanced organic amendment to build fertility before setting out garlic cloves in fall and seed potatoes in spring. It suits growers working in lighter or depleted soils who want slow nutrient release rather than fast-acting salts.
Key specs
- Organic, OMRI-listed formulation (check the current bag label)
- Granular, applied by broadcasting and mixing into the top 6 to 8 inches of soil
- Typical NPK analysis around 3-4-4 (confirm on the package)
Pros
- Releases nutrients slowly across the season
- Easy to broadcast evenly over a raised bed
- Suitable for organic gardens
Cons
- Slower response if a plant is already showing deficiency
- Needs thorough mixing for best results
Fiskars Ergonomic Hand Trowel
This suits home gardeners who plant garlic in neat rows and need to set potato pieces at consistent depths. It is especially useful in dense raised beds where a larger tool would disturb neighboring plants.
Key specs
- Stainless steel blade for planting holes
- Contoured, cushioned handle
- Compact size suited to close spacing
Pros
- Helps create consistent planting depth
- Comfortable for repeated use
- Reaches tight spaces between plants
Cons
- Too small for large-scale planting
- Blade can bend if used to pry rocky soil
Gardener’s Supply Company Soil Thermometer
This is a practical choice for growers who want to confirm soil conditions before planting. Garlic goes in cold soil in fall, while potatoes need soil that has warmed to roughly 45 to 50°F before planting in spring.
Key specs
- Long stainless steel probe for reading at planting depth
- Analog or digital dial readout
- Designed for soil and compost use
Pros
- Removes guesswork from planting dates
- Simple to read at a glance
- Useful for both fall and spring planting
Cons
- Readings are a single point, so check a few spots
- Probe can be fragile in very rocky soil
Bonide Captain Jack’s Deadbug Brew
This is aimed at gardeners dealing with soil-dwelling and foliage pests in potato beds who prefer an organic approach. It can be used as part of an integrated plan alongside crop rotation and row covers.
Key specs
- Ready-to-use organic spray formulation
- Labeled for use on many vegetable pests
- Applied as a foliar spray with a standard sprayer
Pros
- No mixing required
- Fits organic gardening practices
- Easy to apply to potato foliage
Cons
- Must be reapplied after rain and is not a permanent barrier
- Read and follow the label for pest and crop specifics
Vego Garden Raised Bed Kit
This suits gardeners who want a defined bed for garlic and potatoes, especially on poorly drained or compacted ground. Raised beds let you control soil quality, which matters because potatoes dislike waterlogging and garlic rots in wet conditions.
Key specs
- Modular galvanized steel panel construction
- Common bed heights around 11 inches (confirm the model you choose)
- Expandable footprint for adding rows
Pros
- Improves drainage and soil control
- Easy assembly without special tools
- Scalable as your plot grows
Cons
- Soil in raised beds dries faster and needs more watering
- Requires filling with a quality soil mix
Ball Mason Wide Mouth Jars
This is a good choice for growers who want to store cured garlic bulbs and cut seed potatoes in a cool, dry place. Wide mouth jars are handy for organizing smaller quantities of harvested produce.
Key specs
- Wide mouth glass jars with two-piece lids
- Available in multiple capacities
- Glass construction for reuse
Pros
- Easy to fill and empty
- Reusable and widely available
- Keeps produce organized in storage
Cons
- Airtight lids can trap moisture on potatoes, so use vents or leave them loose
- Glass is heavy and breakable
Buying Guide
Choosing supplies for garlic and potatoes companion planting depends on your soil, space and how you plan to store the harvest. The main goal is to give both crops the conditions they need while keeping them healthy alongside each other.
Selection Criteria
- Soil drainage: both crops suffer in waterlogged ground
- Planting precision: garlic and potatoes need consistent spacing and depth
- Pest management: choose options that fit your organic or conventional approach
- Storage: cured garlic and seed potatoes need airflow and darkness
Important Features to Look For
Look for soil amendments with clear nutrient information, tools that let you plant at the right depth without damaging neighboring plants, and containers or beds that drain well. For garlic, aim for planting cloves about 2 inches deep with 4 to 6 inches between cloves. Potatoes are commonly planted 3 to 4 inches deep and spaced 10 to 12 inches apart in rows about 30 inches apart, though exact spacing varies by variety.
Specs to Check
- Soil thermometer range suited to spring planting temperatures
- Bed height and footprint that fit your available space
- Fertilizer analysis and whether it is labeled for organic use
- Jar capacity and lid type for your storage needs
Choosing by Need
- New growers with poor soil: start with a raised bed kit and an organic amendment.
- Experienced growers planting in rows: focus on a good trowel and a soil thermometer for timing.
- Growers with pest problems: consider an organic spray alongside crop rotation.
- Anyone storing a harvest: choose jars or containers that let garlic and potatoes breathe.
Things to Watch Out For
- Do not plant potatoes where tomatoes, eggplant or peppers grew recently, since they share diseases.
- Avoid waterlogged spots, which encourage rot in both crops.
- Keep potatoes out of light after harvest to prevent greening, which can be toxic if eaten in quantity.
- Garlic and potatoes are not strongly beneficial companions in every setup; the main advantage is efficient use of space and a tidy layout, not a proven pest barrier. For broader planning, see Vegetable Gardening Basics: Planting to Harvest.

FAQ
Can you plant garlic and potatoes in the same bed?
Yes, many gardeners do. Because garlic is usually planted in fall and harvested in early summer, and potatoes are planted in spring, the two can share a bed if you schedule them carefully. Keep the bed well drained and rotate the crops in future years.
When should I plant garlic and potatoes?
Garlic is typically planted in fall, about 4 to 6 weeks before the ground freezes, so the cloves can root before winter. Potatoes are usually planted in early spring once soil has warmed to about 45 to 50°F. Check local frost dates for your area.
How far apart should I space them?
Garlic cloves are usually set 4 to 6 inches apart. Potatoes are generally spaced 10 to 12 inches apart in rows about 30 inches apart. Adjust for your variety and bed layout.
Do garlic and potatoes help each other against pests?
There is limited reliable evidence that garlic repels potato pests in a meaningful way in home gardens. Use crop rotation, healthy seed potatoes and appropriate sprays or row covers as your main pest controls.
Why are my potato leaves yellowing?
Yellowing can come from several causes, including nutrient deficiency, overwatering, or disease. Check drainage and soil nutrition first. If problems persist, a local extension office can help identify the cause.
Can I store harvested garlic and potatoes together?
It is better to store them separately. Potatoes need cool, dark, humid conditions, while garlic needs cool, dry, well-ventilated conditions. Mixing them can shorten storage life for both.
Is it safe to eat potatoes that turned green?
Green patches contain solanine, a compound that can cause illness in large amounts. Cut away green areas and deeply green or bitter potatoes should be discarded. If you have health concerns, consult a healthcare professional or local extension service.
Conclusion
Garlic and potatoes companion planting works best as a space-saving, well-organized system rather than a guaranteed pest solution. For improving soil, choose an organic amendment like the Espoma option. For precise planting, the Fiskars hand trowel and a soil thermometer help with timing and depth. Growers dealing with drainage problems should look at the Vego raised bed kit, while those with pest issues may consider the Bonide organic spray as part of a broader plan. For storage, the Ball Mason jars suit smaller harvests if you allow airflow.
