How to Use a Ten-Day Forecast for Planting
Turn temperature, rain, wind, and frost risk into a short list of garden decisions.
Why this label: Plant temperature tolerances, frost injury, water needs, and safe working conditions are established horticultural principles.
Read the overnight lows first
The large daytime number is rarely the whole planting decision. Look at each overnight low and any frost or freeze warning. Cool-season crops tolerate cold that can damage tomatoes, peppers, basil, and other tender plants. When a crop is near its lower limit, waiting a few days is usually cheaper than protecting it every night.
Then look for the establishment window
Transplants often settle in well during a mild, cloudy period with light rain. That does not mean planting immediately before a downpour. Saturated soil can compact, roots can lose oxygen, and exposed seedlings can be battered by wind. Choose the calmer part of the pattern and water the root ball even when rain is expected.
For direct sowing, compare likely rain with seed depth. A hard storm can move shallow seed or crust the soil surface. A dry forecast is workable if you can keep the seedbed consistently moist through germination.
Make four decisions, not forty
Use the forecast to answer: What can go in? What should wait? What needs protection? When is the best work window? Then check conditions again the morning you act. Sonic Weather and the planned Sonic Garden dashboard are intended to make that final check quick.
