How To Grow Asparagus Indoors

Asparagus is a vegetable loved by many to use as a side to their dish or to simply give it that green picturesque perfection. When grown properly it’s very tender and quite scrumptious. The benefits of Asparagus keep going on, it has been proven tremendously beneficial for medicinal purposes, to such an extent that it is even used to make medicines! However, all these ups come at a cost. Choosing to grow asparagus indoors is not an easy task and not for one who lacks patience. If you are a gardening enthusiast who likes to grow their own healthy food, we have just the right information to get you going! 

Growing Asparagus Inside

Asparagus is a relatively huge vegetable, they grow fern-like foliage that goes up to 3-5 feet high and 1-3 feet wide. It is a complicated enough task to grow them outside, but to grow it inside without the right guidance and tools is nearly impossible. But that’s why we are here to help you through it! We will make sure that you get the optimum yield of what you plant. Asparagus outside may yield for a decade, but inside it can at best yield for three to four years after maturing. 

Materials Required to Grow Asparagus Indoors

The first thing you will need to do is find big containers, 8” deep and 3-6 feet wide. Depending on how much you plan on planting in a single container, we recommend you only plant one crown per container. As asparagus is preferred to grow outside, we need to make our conditions meet as similar as that, hence you need a well-lit room with direct sunlight getting to the containers. You need a growing medium, such as soil. However, you need to make sure the medium is not too clayey or the water will not drain well enough. Asparagus grows best in well-drained soils. 

1. Containers 8” deep, 3 – 6 feet wide

2. Potting soil

3. 5-10-10 fertilizer

4. Water

5. Sunlight

6. Live Asparagus crowns –

This is a shortlist of what you will require to grow your asparagus indoors. We suggest one-two-year-old crowns as they are easily available in the market even though a bit costlier than seeds but these take significantly less time to yield a crop. To make things easier you can get all-male hybrids so the hassle of plucking out the ones that grow seeds that ruin the crop doesn’t have to be done. 

The Planting and Care of Asparagus

It is best to plant asparagus in March as they grow best then. Here’s How to plant asparagus crowns:

1. Fill the containers with soil.
2. dig six inches’ holes in the soil
3. Place the asparagus crown in the hole, spreading the roots evenly
4. Fill the hole with two inches of soil. Keep adding soil and a bit of fertilizer, a total of two inches by the end, as the ferns grow along during the season. 

Plant all the crowns following the above steps. Plant them at least 18 inches apart from each other as asparagus best grow by themselves. You need to add compost and balanced fertilizers during the growing season and after harvesting. Keep the medium well moist with water. 

Now if you bought the crowns that produce little red seeds along the way you must pluck them out otherwise, they will use up all of the nutrients making your yield less than optimum. For winter seasons of dormancy, your plant needs cooler temperatures which can be achieved by moving your plant outside for that period. Asparagus requires an entirely weed-free environment so make sure you pick out the weeds in time.
