Soil, Water, Fertilizer for Asparagus Fern Indoor Plant Care 

  • Soil – Use loose well-drained soil when planting your fern in pots or containers. Asparagus fern tolerates slightly acidic soil conditions.
  • Adequate water – Keep the fern well watered in all seasons. Keeping it well hydrated takes a little effort. As we have seen above, this plant thrives on humidity and the indoor climate can often be dry. It may dry out to the point that it appears dead, but outdoor spring temperatures and misting daily will revive it. Make it a habit to mist the plant daily especially the arching stems.
  • Fertilizer – for your asparagus fern to thrive, it will need some fertilizer. Feed it with liquid or water-soluble all-purpose plant food. You can dilute it to ½ strength so that it does not overpower the plant. During summer, the plant may need weekly or monthly feedings.
  • Repotting – They don’t mind being pot bound and can grow for 2 years without repotting. For successful repotting, divide the plants into big clumps and remove the underground roots when dividing. Place the divided plants into good-sized pots in order to retain their tight growth habit. This fern type does not need large pots as they are slow growers.
  • Prune out the Dead Stems. Asparagus fern grows wildly if allowed to. To maintain it, you will need to prune out dead stems. Always wear gardening gloves when pruning mature plants to avoid injury.
  • Toxicity Info – Asparagus fern has a high toxicity level in its red berries. If you eat these berries, they can cause digestive problems, so avoid them at all cost
