How To Grow Gerbera Daisies Indoors

Gerbera Daisies (Gerbera Jamesonii) can in fact be grown as perennials indoors, flowering all year long. Caring for them as a houseplant not only livens up your home but purifies your indoor air of toxins. They are listed in the top 12 “Green” air cleaners by NASA. People are catching onto this fact, but they haven’t quite figured out how to grow them and care for them. gerbera daisies

You can purchase giant gerber daisies at your local garden center or you can buy them online. The other alternative is to purchase seeds and grow your own. Some people are successful at germinating the seeds of the gerbera daisy plants they bought. The seeds have a short shelf life so you will want fresh seeds wherever you get them.

How to Grow Gerbera Daisies From Seeds
For earliest flowering start the seeds indoors. The seeds have fuzz on one end. The thin ones can sometimes be infertile, so you want to look for the fat ones. When you plant them make sure to place the seeds vertically with the fuzz on top. Plant them directly in a shallow container with moist soil. Peat moss or peat moss pellets work well. You want them just under the soil line so that the little fuzz is almost poking out. They need light and warmth to germinate so place the pot in a warm sunny location that’s about 70 degrees. Germination takes around 15-20 days at 70 degrees. I recommend covering the pot with clear plastic wrap as this will keep the soil warm and moist. Always make sure the soil is moist when germinating. 

After the seeds sprout provide plenty of light and avoid excessive watering and drafts. When 4 leaves develop you can transplant them to larger pots. Gerbera roots are quite sensitive  so you have to be gentle when handling them.  If you want to grow them outside set the pots outside in a protected area to harden for 3 days. Then plant them in compost rich garden soil with plenty of sun and water them well initially.  Adding some high energy fertilizer (high potassium) in with the water will help grow vibrant flowers.

How to Care For Gerbera Daisies
Gerbera daisies flower best when planted in 6 or more hours of direct sunlight each day. A high source of light can give an abundance of flowers. Gerber daisies need to be kept evenly moist but they should be allowed to dry slightly before watering. Gerber daisies require well-drained potting soil that is nutrient rich. In Mel Bartholomew’s book “All New Square Foot Gardening” he states that the very best soil for anything, plant or vegetable, is 1/3 compost, 1/3 peat moss, and 1/3 vermiculite. Healthy Gerberas are rarely ever bothered by pests, however fungus and stem rot is a common problem with over watered plants. You might want to remove old leaves regularly to prevent fungus infections.


Gerbera Daisies Purify Indoor Air


If you have a home, a window, and some sunlight, why not have Gerbera Daisies somewhere near? It’s a known fact that these happy, colorful, wonders of nature purify your indoor air unlike any “cover up” spray could pretend to do.

Commercial air purifiers can be toxic because they emit ozone gases or ultraviolet rays. Not only that, they are not removing those chemicals in your home. With closed windows in the cold months, and air conditioning in the summer, those chemicals have no place to go.

Wait what chemicals? Well, there are many, but some of the most lethal and common chemicals found floating around in the typical home are:

  • Formaldehyde
  • Tricholorethylene
  • Benzene.

And where do they come from you ask? Formaldehyde comes from such places as foam insulation, plywood, particleboard, clothes, carpeting, furniture, paper goods, household cleaners, and water repellents. And tricholorethylene comes from dry cleaning, inks, paints, varnishes, lacquers, and adhesive. And the always present benzene comes from tobacco smoke, gasoline, synthetic fibers, plastics, inks, oils, and detergents.

Most people know that plants give us fresh oxygen and take in the stale carbon dioxide that we exhale. A life sustaining relationship that we all too frequently take for granted. Well, recently we discovered that certain plants go a bit further and filter out these deadly toxins and pollutants in our air. Recently, NASA researcher Dr. Bill Wolverton placed houseplants in sealed chambers and exposed them to hundreds of chemicals, and found plants like the gerbera daisy suck the chemicals out of the air.

There has never been a more appropriate time than now for people to get back to their roots and embrace plants for pollution free homes and work places.

Top 12 “Green” Air Cleaners

Besides Gerbera Daisies, there are several other species that perform this air purification miracle. Wolverton found the top 12 houseplants that help to filter and clean indoor air most efficiently are:

  1. Chinese evergreen (Aglaonema pseudobracteatum)
  2. Peace lily (Spathiphyllum ‘Clevelandii’)
  3. Arrowhead vine (Syngonium podophyllum)
  4. English ivy (Hedera helix)
  5. Corn plant (Dracaena fragran ‘Janet Craig’)
  6. Devil’s ivy (Scindapsus aureu)
  7. Bamboo palm (Chamaedorea seifrizii)
  8. Rubber plant (Ficus robusta)
  9. Gerbera daisy (Gerbera jamesonii)
  10. Florist’s mum (Chrysanthemum morifolium)
  11. Boston fern (Nephrolepis exaltata ‘Bostoniensis’)
  12. Dwarf date palm (Phoenix roebelenii)

Air Filtration and Purification with House Plants

I think many people underestimate the benefits of having plants in your home. Not only to they provide oxygen for you to breath while removing the carbon dioxide you exhale, but they purify many toxins and pollutants from the air. Through a process called “off-gassing” many chemical compounds are released into our air and they often come from everyday items present in our homes and office. And as we all know, our air is polluted as a result of all the processes in manufacturing and big industries as well.


Because of present day air pollution levels I can’t think of a better time for people to get back to their roots (no pun intended) and begin to use these little wonder plants in their home to renew stale indoor air. Did you know plants even remove tobacco smoke as well as dust from the air? They can even help with allergies. While it is safe to assume all plants purify our air, NASA showed that some plants are better than others.

The most efficient removal of formaldehyde:

  • Philodendrons
  • Spider plants
  • Pothos

The most efficient removal of benzene (a known carcinogen):

  • Gerbera Daisies
  • Chrysanthemums

Not only are these the best plants to use for purifying indoor air but they are some of the easiest to grow. As a rule of thumb, allow one houseplant per 100 square feet of living area. The bigger the plant, the more air it can filter.
