Grow Sequoia Strawberries Like This If you want big, sweet, juicy berries that actually taste like strawberries, plant Sequoias. Here’s the secret: Soil: Use loose, well-draining potting mix. I like a blend with compost and a little perlite so roots stay airy. Strawberries hate soggy soil. Container: Minimum 12-inch wide pot, but bigger is better. Think wide and shallow so they can spread. Hanging baskets work beautifully too. Size: Sequoias produce large berries. Not the tiny grocery store kind
