Siltwell is the gardening app that actually knows your garden.
Most garden apps guess. Siltwell plans around your real beds, your real crops, and your real weather — so the advice fits your yard, not a generic calendar.
PLAN YOUR GARDEN (free)
• Visual layout editor — draw your beds and place what you're growing
• Crop-rotation and companion-planting warnings built right into the layout
• A curated catalog of 150+ vegetables, herbs, and flowers with real growing data
• Succession planning — queue what's next and get a nudge when it's time to sow
• A planting calendar built from your frost dates — see what still fits before first frost
TRACK WHAT ACTUALLY HAPPENS (free)
• Garden journal with photos
• Harvest tracking that adds up your yields
• Year-over-year history — build a season record to compare against next year
• Works offline — log and plan without signal; it syncs when you're back
WEATHER THAT KNOWS YOUR YARD (free)
• Watering guidance that reads the forecast — skip the beds it just rained on
• Frost and care reminders tied to your location, not a one-size calendar
