PlantSowGrow
For gardeners who forget what comes next
Know what to do in your garden, and when.
Add the plants you want to grow. PlantSowGrow works out your frost dates from your town and gives you each job on the right day — sow, pot on, harden off, plant out, feed, harvest.
What it does
A growing plan that keeps itself up to date
Every plant comes with its whole season mapped out. You tick jobs off; the next one appears with its date already worked out.
📅
Jobs on the right day
Sowing windows, potting on, hardening off and planting out are timed from your own last and first frost.
🌍
Frost dates from your town
Search your town once. We average ten years of local temperature records to find your frost dates.
🔔
Reminders
A reminder the day before and on the morning of each job, so nothing slips by.
🏡
Indoors, outdoors or greenhouse
Start seeds on the windowsill and plant out later, sow straight into the ground, or grow under glass.
🌳
Trees and perennials
Pruning, feeding and mulching come back every year at the right time, without you setting anything up.
📷
Photo journal
Keep photos of each plant as it grows and share a before-and-after card.
How it works
From seed packet to harvest in three steps
