What are some of your favorite fertilizers to use on your houseplants?

I'm looking for some new products to try and would appreciate suggestions.

I try to use organic products outside, but the smell from the organic fertilizers doesn't work for me in the house.
(Plus, many don't work well in a soilless mix/container situation.)

I'm really sensitive to smells, so strong chemical odors won't work either.

I'd like to use something complete with micronutrients.

The plants involved would be things like Begonias, Gesneriads, Pilea, etc., as well as seedlings of plants destined for the outdoors. They are grown in a soiless, peat-based mix (Pro-Mix or similar).

Dyna-Gro and Algoplus are a couple of product lines that I'm considering. Opinions? Do they have a strong chemical smell?

Thanks much!

A friendly suggestion - be careful on feeding house plants. Most people get carried away. I have many plants and rarely feed them.
You cannot beat Azomite for micronutrients. No smell.

When it comes to indoor plants, fertilizer is vastly over-rated and over-promoted by manufacturers and retailers. The packaging seems to imply that there is a special fertilizer for every different type of plant species so you will buy lots of different kinds and waste most of them.

In reality, most indoor plants use nutrients in extremely minute quantities and need replenishment infrequently. The specific nutrients needed and in what proportions are well known. (See the Dyna Gro Foliage Pro label for that information.)The addition of vitamins and hormones and anther additives is a waste. Don't waste your money on products like Superthrive.

The use of organic vs commercially manufactured fertilizers is a matter of personal preference. The plants don't care about the source of the nutrients as long as they get an adequate supply of those they need.

Plants that are ailing, languishing or simply growing very slowly in low light do not need any fertilizer. Only plants that are healthy, growing vigorously and have not been repotted in at least 2 years need fertilizer.

Whatever fertilizer you use for your indoor plants should be diluted to half-strength recommended on the label. The label directions are based on plants growing in the ideal environment of the greenhouse, not our homes, so they needed to be diluted.

Dyna-Gro has a variety of fertilizers that are available. If you stick with their Foliage Pro it will be fine for all your indoor plants. It is complete and includes minor and trace elements as well as the macro nutrients. It is a liquid that you dilute and it has no odor that I have detected. If you prefer another product then check the nutrient list on the Foliage Pro label to determine just want nutrients your plants will need from any other fertilizer. Always refer to the small print nutrient list on the label and ignore the bold print marketing hype.

If a plant shows symptoms of what online photos say are nutrient deficiencies, check the soil and water pH first. If the pH is not in the appropriate range (6.0-6.8 for most tropical plants), then even when the soil nutrients are abundant, they will be insoluble and unavailable for the roots to absorb. Improper pH is a much more common problem than actual nutrient deficiency. This is particularly a problem if your local tap water is on the hard side.

Sorry for the lengthy reply, but I know that there is so much hype and misinformation about fertilizing that I have taken the opportunity to present this information.

That was a very informative and helpful reply, Will.

I use the DynaGro Grow liquid fertilizer (7-9-5) which has no particular smell (that I can detect) once diluted. I use it diluted 0.5 tsp in 5 liters (about 1 gal) with every watering, which is roughly the dosage recommended on the label. My indoor plants are all succulents.

I've used Osmacote for years for my houseplants. One application lasts years for me. There is no smell and it feeds a tiny bit with each watering.

I haven't fertilized anything yet, but I'd like to use fish emulsion when I do. Stinks, bur only for a day.

Can't get any better advice than already given.

I used fish emulsion one bottle worth, once. To me, It gave my plant soil a nice earthy rich organic smell like forest soil.

I try to use rainwater and assume it carries tiny amounts of organic matter. I am naive though, it is likely acidic, but potted plants seem happy. I should test it!

I now have MSU fertilizer for my orchids- different case from typical potted plants, and have had a good year with the Phalaenopsis maybe helped by that.

Thanks to everyone for their responses!
I'll be back later with a longer reply, but just wanted to check in and say
