If you have ferns that are already growing in your garden, you likely won’t need to move them unless they’re showing signs of ill health. Ferns like lots of shade and moisture, and do well under the canopy of a few other larger plants or trees. Plant (or transplant) ferns onto a plot that gets northern sun and no direct sunlight. If ferns are left in an area with direct sunlight, their leaves will burn.
 If it does not rain regularly in your area, you’ll need to water your ferns on a daily basis so that the soil is kept moist. Add a dense layer of pine needle or leaf mulch to the tops of your ferns; about 2–3 inches (5.1–7.6 cm) thick is ideal. This will help to lock in moisture and keep the rate of evaporation relatively low, so that the air near the ferns is a bit more humid.
 Six months after the original planting, you can begin fertilizing the ferns for added growth. Select an organic fertilizer that is spray-on, and apply it to the ferns (following package directions). Additionally, you can add a layer of compost and mulch to the soil to create a better growing environment for the ferns. Do keep in mind that ferns have a lesser requirement of fertilizer than other common houseplants.
 Ferns don’t have many natural predators outdoors, other than slugs and one or two rare diseases. If, however, you notice that your fern has damaged or diseased fronds, use a pair of gardening shears to cut them back. This will keep the integrity of the rest of the plant, and if it is a disease, prevent it from spreading to other plants.
 Ferns can get quite large over time, and require splitting and transplanting. To divide a large fern into several smaller ferns, carefully dig out the plant and its roots. Carefully break apart the plant into sections; typically, the fern will grow in clumps making it easy to split. Then replant each of these, and water them well.
Plant ferns in the ideal location.
Keep the soil moist.
Fertilize the ferns once a month.
Cut back damaged fronds.
Transplant if necessary.
