Deer tend to prefer tastier plants, meaning they will avoid giant ostrich ferns. Smaller ostrich ferns thrive in a large planter or container on a deck or balcony, provided they are not in full sunlight. Giant ostrich ferns are perennials, so they can be expected to grow in lawns or gardens year after year. Their hardiness makes them ideal for difficult-to-plant regions, including those receiving frost and snow in the winter. This fern produces a new set of new fronds, called crowns, each year surrounding the previous year's growth. This means that the fern will consistently grow in size year after year. Once the fern reaches its desired size, it can be easily divided by splitting the root ball and replanting each half. Website: https://www.gardenplantsnursery.com/ostrich-fern-for-sale/
