Balmoral Squash A compact summer squash with a neat growth habit producing white scalloped fruit throughout the season. The plant has a relatively open habit and large leaves and is quick to establish in pots and containers. Balmoral is also an ideal product for open ground production and will thrive in most soil types. Fruit can be harvested young, when they are about 3-4in (7-10cm) for uses similar to Zucchini or left to grow larger for use as a squash.
