What Weeds Reveal: Using Garden AI to Diagnose Soil Problems

What Weeds Reveal: Using Garden AI to Diagnose Soil Problems

After publishing our recent article on what weeds reveal about your garden soil, we decided to put our research to the test in the field. We collected photos of various weeds growing in the garden and ran them through the garden’s artificial intelligence, which quickly identified each plant. With correct identification, we were able to determine the specific soil conditions that allowed each weed to thrive. Understanding these conditions is imperative to correcting soil imbalances that encourage weed growth and hinder robust crop production. Here are our findings.

	Lapsana communis/Nipplewort Saturated, fertile and shaded soils – often well-off in nitrogen. Clay or silty soils with good organic matter. Areas with little soil disturbance (e.g. under bushes, near fences or shady beds).
	Lady’s Thumb/Wisdom/Redshank Saturated, compact soil. However, this plant can grow almost anywhere.
	Yellow sedge/nutgrass Needy drainage or saturated soil. compact. high fertility.
	Crabgrass Compact soil/low fertility. Bare or lean turf. droughty and warm areas.
	Cypress Vine / Cardinal Climber While it is not technically a weed (it is often cultivated intentionally for its attractive red, trumpet-shaped flowers and fern-like leaves), it can behave like a weed if it self-seeds and spreads aggressively. This vine suggests robust, moderately fertile soil.
	Wild Arugula / Wall Rocket Fertile, nutrient-rich, damp soil.

	Hairy Galinsoga You may be overfeeding with nitrogen-rich fertilizers (compost or manure). Next season, reduce your seeding a bit and focus on balanced fertility.
	Golden rod It is a native, perennial wildflower in the Asteraceae family, often incorrectly referred to as a “weed” because it spreads aggressively throughout gardens, fields and borders.
	Yellow Nutcracker It is a perennial grass-like weed from the Cyperaceae family, one of the toughest garden weeds due to its underground tubers. This spot is too saturated, probably compacted and sultry – perfect for tomatoes or peppers, but unless drainage is improved it will be a nut spot.
	Chickpeas This place is frigid, damp, nitrogen-rich and partially shaded – perfect for growing lettuce, spinach or brassicas, but also chickpea nurseries.
	Spurge The soil is warm, droughty, compact and not very fertile. It is most likely on a path, edge of a row, or a loaded area.
