Welcome to the world of asparagus ferns, where the green is greener and the gorgeous is, well, more gorgeous. If you're looking to add a touch of lush, tropical appeal to your garden, you've come to the right place. In this guide, we'll unravel the secrets to growing a thriving asparagus fern garden that will make your neighbors green with envy. So, strap on your gardening gloves, grab your watering can, and let's get started.

Understanding the Asparagus Fern

First things first, let's clear up a common misconception. Despite its name, the asparagus fern isn't actually a fern. Shocking, right? It's a member of the lily family, closely related to the edible asparagus. This cheeky plant got its name from its fern-like appearance, with delicate, feathery foliage that's as soft as a kitten's fur.

Native to South Africa, the asparagus fern is a hardy plant that can thrive both indoors and outdoors. It's a fast grower and can reach up to three feet in height and width. Its vibrant green leaves and tiny white flowers make it a popular choice among gardeners looking to add a touch of the tropics to their garden.

Types of Asparagus Ferns

There are several types of asparagus ferns, each with its own unique charm. The most common type is the Asparagus densiflorus 'Sprengeri', also known as the emerald fern. It's loved for its arching stems and feathery foliage. Then there's the Asparagus densiflorus 'Myers', or the foxtail fern, which is known for its upright stems that resemble a fox's tail. And let's not forget the Asparagus setaceus, or the lace fern, with its delicate, lace-like foliage.

Each type has its own care requirements, but don't worry, they're all relatively easy to grow. So, whether you're a seasoned gardener or a newbie with a brown thumb, you can grow a lush asparagus fern garden with a little bit of patience and care.

How to Grow an Asparagus Fern Garden

Now that we've covered the basics, let's dive into the nitty-gritty of growing an asparagus fern garden. Here's a step-by-step guide to help you get started.

Step 1: Choose the Right Location

Asparagus ferns love bright, indirect light. So, choose a location that gets plenty of light, but not direct sunlight, which can scorch the leaves. If you're growing your ferns indoors, a north or east-facing window is ideal.

These plants also love humidity, so they'll appreciate a location near a water feature or a humidifier. If you're growing them outdoors, they'll do well in a spot that gets morning dew or is near a sprinkler system.

Step 2: Prepare the Soil

Asparagus ferns aren't too picky about the soil, but they do prefer a well-draining mix. You can use a standard potting mix and add some perlite or sand to improve drainage. The soil should be slightly acidic, with a pH between 6.5 and 7.5.

Before planting, make sure to loosen the soil to improve aeration. This will help the roots spread out and establish themselves more quickly.

Step 3: Plant Your Ferns

Once you've prepared the soil, it's time to plant your ferns. Dig a hole that's twice as wide and as deep as the root ball. Place the plant in the hole, making sure the top of the root ball is level with the soil surface. Then, backfill the hole with soil, firming it gently around the plant.

After planting, give your ferns a good watering. This will help settle the soil and ensure the roots make good contact with the soil.

Caring for Your Asparagus Fern Garden

Now that you've planted your ferns, it's time to learn how to care for them. Here are some tips to keep your asparagus fern garden looking lush and gorgeous.


Asparagus ferns like to stay moist, but not waterlogged. So, water them regularly, but make sure the soil drains well to prevent waterlogging. A good rule of thumb is to water when the top inch of soil feels dry to the touch.

During the growing season, you might need to water your ferns more frequently, especially if the weather is hot and dry. In the winter, you can cut back on watering, as the plants enter a dormant phase.


Like all plants, asparagus ferns need nutrients to grow. Feed them with a balanced, water-soluble fertilizer every two weeks during the growing season. In the winter, you can reduce feeding to once a month.

Remember, over-fertilizing can be just as harmful as under-fertilizing. So, follow the package instructions carefully and avoid the temptation to give your plants an extra dose of nutrients.


Asparagus ferns are fast growers, and they can get a bit unruly if left unchecked. So, don't be afraid to give them a good trim. Pruning not only keeps your plants looking neat and tidy, but it also encourages bushier growth.

The best time to prune is in the spring, just before the growing season starts. Use a sharp pair of pruning shears to cut back any dead or yellowing fronds. You can also trim back any overly long or unruly stems to maintain the shape of the plant.

Frequently Asked Questions

Are asparagus ferns toxic?

Yes, asparagus ferns are toxic to pets and humans if ingested. They contain sapogenin, a compound that can cause skin irritation and stomach upset. So, keep them out of reach of curious pets and children.

Do asparagus ferns produce flowers?

Yes, asparagus ferns produce tiny, white flowers, usually in the summer. The flowers are followed by small, red berries. While the flowers and berries add to the plant's charm, they're not the main attraction. The real show-stopper is the lush, feathery foliage.

Can asparagus ferns grow in low light?

Asparagus ferns can tolerate low light, but they won't thrive. They prefer bright, indirect light. In low light conditions, their growth may be slower and the foliage less vibrant.

How often should I repot my asparagus fern?

Asparagus ferns are fast growers, and they can quickly outgrow their pots. You should repot your ferns every 2-3 years, or whenever the roots start to crowd the pot. Choose a pot that's one size larger than the current pot, and make sure it has good drainage.


There you have it, the secret to growing a lush asparagus fern garden. With a little bit of care and attention, you can transform your garden into a tropical paradise. So, what are you waiting for? Get your hands dirty and start planting!

Remember, the journey is just as important as the destination. So, enjoy the process of nurturing your plants and watching them grow. After all, gardening is not just about the end result, it's about the joy of growing.
