From sow date to harvest window - automatically
Every vegetable has a predictable timeline from sowing to germination, from germination to transplant (for indoor-started plants), and from transplant to harvest. The problem is that this data is scattered across seed packets and supplier websites - and it changes based on your actual sow date. The today marker line crosses all bars on the chart, so you can see at a glance: are your tomatoes still germinating, in the grow phase, or approaching harvest?
Understanding Gantt charts and succession planting
A Gantt chart shows each phase (germination, transplant, growing, harvest) as a colored bar on a horizontal timeline. Succession planting means sowing the same crop in batches 2-4 weeks apart, so you get a continuous harvest rather than everything ready at once. For lettuce, radishes, and herbs this prevents a glut followed by nothing.
FAQ
How long does it take to grow tomatoes from seed?
Tomatoes take 7-10 days to germinate, then 6-8 weeks before transplanting outdoors. From transplant to first harvest is another 6-8 weeks depending on variety. Total from seed to first ripe tomato is typically 75-120 days. The calculator shows the full timeline from your actual sow date.
What is succession planting?
Succession planting means sowing the same crop in batches 2-4 weeks apart, so you get a continuous harvest rather than everything ready at once. For lettuce, radishes, and herbs this prevents a glut followed by nothing. The calculator shows when to start your next succession sowing for continuous harvest.
Can I track multiple vegetables in one garden?
Yes. Add as many vegetables as you like, each with their own sow date. The calendar shows all of them on one page with a today marker line crossing all bars so you can see at a glance which plants are in which phase right now.
