When is the ideal time to start planning a spring garden?

Prof. Samuel Fitzgerald, Ph.D.Half of your spring garden planning starts 6-8 weeks before your last frost date. For instance, coastal gardeners might start planning their layouts in January while cooler, frost-prone mountain areas of the region may wait until March. I planted my tomatoes too early one year in Zone 5. Most of those plants didn't make it through our late frost that year. Make sure you monitor your regional dates. There's no way to prep the soil too early.
Soil Testing
- Collect samples when soil thinks 6 inches deep
- Aim for pH 6.0-7.0 for most crops
- Add compost if organic matter falls below 5%
Seed Starting
- Begin broccoli indoors 10 weeks pre-frost
- Tomatoes need 6-8 weeks under grow lights
- Harden seedlings outdoors gradually
Tool Readiness
- Sharpen pruners to 20° angles
- Oil hinges with linseed oil
- Test hoses for winter cracks
Be vigilant for frost dates. Use your USDA zone map and consider using a soil thermometer. Coastal gardeners know fecundity depends on watching for early spells of warmth. In Oregon, I lost peas to a false spring. Mountain growers notice snowpack where it lingers longer. Be mindful of microclimates. South-facing slopes will thaw first.
Irrigation Setup
- Test drip lines for 1 gallon/hour flow
- Position sprinklers 15 feet apart
- Repair winter cracks with heat-shrink tape
Seedling Care
- Rotate trays daily for even light
- Water from below to prevent damping-off
- Use 40-watt LEDs 6 inches above plants
Consistency beats speed. For tools, clean and disinfect every two weeks - it reduces disease spread by 75%! One client with a blight outbreak reported it completely stopped after we soaked her pruning shears in 70% alcohol for 10 minutes. Test your wheelbarrow tires and make sure they are inflated to 20-35 PSI. Low pressure manifests like back strain due to the vehicle pushing back against you, and overinflated can pop tires on rocks.
