Requirements, Plant Care, and Maintenance
Soil
Zucchini grows best in sandy, fertile soils, with a pH between 6.0 and 6.5. Remove all rocks and work the soil several weeks before planting. Summer squash grow best in soil with lots of organic matter. Spread 2-3 inches of compost material on the growing area and mix into the top 8-10 inches of soil.
Fertilize after the first blooms appear.
Water
Water the plants enough to keep them from wilting. If the weather is really dry they should be watered at least once a week.
Can benefit from a 2 inch layer of straw mulch, and/or an olla to assist during the summer.
Support
Many squashes can be staked, trained, and trellised vertically to reduce the space they take in the garden, however it’s not required if you have a large enough area for the vines to spread.
Pruning
It can be beneficial to prune leaves that are below harvested fruit. This makes future harvesting easier and can prevent mold and other decomposition diseases.
Tips and Tricks
- Growing vertically is my biggest tip with these varieties. It can be a great space saver in the garden as well as provide shade for companion plants.
Harvesting and Using
Harvesting
Storing
- Fresh at room temp (short term)
- Freeze-dried
- Blanched and frozen
- Canned (pressure canned)
Seed Saving/Heirloom notes
Leave a squash to mature on the vine long past the point of typical
harvest, likely until the end of the season and the rest of the plant is
dying back. It will get quite large, have an extremely hard shell, and
when opened will have large hard seeds. Seeds must be fermented for 3-4 days before fully drying.
Seeds can only be saved from open-pollinated (heirloom or heritage) to ensure that the fruit will be similar to the parent.
To prevent cross-pollination, an isolation distance of 1/2 to 1 mile is recommended, otherwise hand pollination may be required in smaller gardens.
