Kauai County Vegetable Planting Period Guide
UH CTAHR Kauai County table for vegetable crop-window rows, seasonal cool-crop timing, spacing fields, harvest days, and source-age caveat.
Climate signals
- UH CTAHR Planting, Harvest Periods and Spacing of Vegetables is a University of Hawaii Cooperative Extension table compiled by Richard Ebesu in April 1993 for Kauai County.
- The source says planting and harvest periods will vary depending on variety, temperature, and climates.
- The table labels crop rows with C meaning cool climate, M meaning mild climate, and W meaning warm climate.
- The table provides best time to plant, row spacing, plant spacing, and days to harvest fields for each crop row.
- The PDF cautions that it may no longer represent the most up-to-date information, especially if it contains pesticide uses that are not currently licensed or labeled for Hawaii.
Planning notes
- Use the crop windows as Kauai County crop-window timing signals, not cultivar-specific guarantees or current pesticide guidance.
- Bush beans are year round; Swiss chard, sweet corn, and cucumber are year round; eggplant, okra, green onion, radish, and tomato are year round.
- Cool-climate rows include beets Sept-Apr, broccoli Sept-Apr, head cabbage Sept-Feb, carrots Sept-Apr, leaf lettuce Sept-Feb, spinach Nov-Mar, and turnips Sept-Apr.
- Other source rows include bell pepper Sept-Apr, pumpkin Mar-Aug, and watermelon Jan-June.
- The table also has source rows for summer squash and winter squash, but this guide does not link the catalog's winter-squash varieties because the source row split is too easy to overstate.
- Use these priority catalog links as crop-level examples, not UH CTAHR cultivar recommendations.
