The recommended spacing for planting zucchini varies somewhat depending on the growing method and variety, but generally:
- When planting seeds directly, sow them about 3 to 4 inches apart in rows that are 2 to 3 feet apart. Once seedlings are 4 to 5 inches tall, thin them to be spaced 6 to 8 inches apart
- For mature plants, spacing can range from about 1 foot apart for compact varieties to 2 to 3 feet apart for larger vining zucchini plants. Rows should be spaced at least 3 feet apart to allow for growth and access
- If growing vertically or staking/pruning, plants can be spaced closer, about 1 foot apart with rows 1.5 feet apart, since pruning controls spread
- Another approach is planting in hills of 2 to 3 plants spaced 3 to 4 feet apart within rows spaced 4 to 6 feet apart, which is common for larger squash varieties
In summary, for most home gardens, planting zucchini about 1 to 3 feet apart within rows, with at least 2 to 3 feet between rows, works well. Closer spacing is possible with pruning or vertical growing, but adequate space ensures good air circulation, reduces disease risk, and allows plants to reach full size and productivity
