Sow and Plant

Sow seeds 1 inch deep in spring, either in rows or hills. Also may be started from seedlings started indoors or purchased at stores.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.


Keep plantings small, to fewer than a dozen plants. Different types of summer squash help pollinate one another because they are of the same species.


Harvest summer squash when they are young and tender, before the rinds begin to harden. Use a knife to cut fruits from the plants.


Squash bugs and squash vine borers can be serious pests. Exclude them from young plantings with row covers.
