What to plant this week in Syracuse, NY
With average last frost dates around April 21, Syracuse gardeners are currently in the late spring transition window where early cold snaps can still damage tender crops like Basil and Zinnia. While you cannot sow new seeds this week due to lingering chill risks, it is the perfect time to transplant your warm-season harvestables like Bush Beans and Cucumber into the warming soil.

Seasonal tips

- Pinch back the tips of basil and okra to encourage bushier growth rather than flowering too early.
- Add a thin layer of straw or shredded leaves around heavy feeders like pumpkins and squash to retain moisture.
Pest & disease watch
- Spider Mites often surge on stressed Bush Beans and Zucchini during our humid spring weather; inspect undersides of leaves daily.
- Slugs and snails are active now in wet Syracuse soil, targeting low-growing lettuce substitutes like Malabar Spinach before they harden off.
- Aphids frequently colonize new growth on Zinnias and Cosmos as temperatures rise above 50°F.
Watering this week
Provide about 1 to 2 inches of water per week, applying it deeply in the morning to reduce evaporation and disease risk.
Harvest zucchini and summer squash early in the day when they are most tender and flavorful for your table.
Syracuse gardening questions
3Can I plant Tomato or Pepper seeds indoors this week?
No, Syracuse soil is too cold for immediate outdoor planting, and you must wait until mid-May to harden off seedlings safely. Start warm-season transplants like Basil now under lights if they are not yet hardened.
When should I stop watering my newly planted Cucumber and Squash?
Continue consistent watering during our variable Syracuse springs, especially as the soil is often dry from winter freeze-thaw cycles before rain arrives.
Is it safe to harvest my Potato crop now?
Check for small, firm potatoes if you planted early varieties, but wait until after the first frost of October 17 to fully mature storage tubers.
