I fertilizer with K-Mart brand cheap power that you mix with water. I use almost nothing, or very very little when I water. You can do more harm than good over fertilizing. If you don't at all, you still get good results with Sans.

I also use Alfalfa tablets that is used for a dietary supplement. I put 10 in a shaker bottle and add to a gallon water container. Water just a little to each plant. It is a growth hormone. It is safe and can't hurt but it does stink! So I use it only in early summer or late spring so nothing smells when I bring them in for the winter.

I use Jack's or Foliage Pro. I prefer organic but I was told by a nursery owner containers don't have the same microbes as the earth to break down organics so it's best to stick to Osmocote, Miracle Gro, etc. Although, I do put cottonseed meal on other containered plants (blueberries) as it's acidic.

I was told by a forum member (who grows the most beautiful sans) to use Osmocote with the green lid for sansevieria. Three shakes on top of your soil, it's slow release.

Hi akrrm, thanks for the advice!

I found 2 Osmocote products on eBay. The green lid one says for "flowers and vegetables" and is a 14-14-14 mix and feeds for 4 months. There's also a pink lid one that say "indoor and outdoor" plants that's a 15-9-12 mix and feeds for 6 months. Don't know which to get...

I have been using Osmocote too. So easy. I think the 15-9--12 is new. I bought a bottle of it, but the 14-14-14 has been working for a long time. I am going to experiment with the new one.

I was told to use the one with the GREEN lid.

I think nurseries tell you to use the green lid because it gets the plants growing so that they can sell them. It might not be in the plants best interest. I've been using the pink top for 10 years.

I found this (Sanseveria Production Guide):

"Potted greenhouse-grown sansevieria should receive the equivalent of 1.7 pounds of actual nitrogen (N), per 1000 square feet per month from a 3-1-2 or 2-1-2 ratio fertilizer." http://mrec.ifas.ufl.edu/foliage/folnotes/sansevie.htm

"Nutrient Elements and Soil pH. Ten to 12 fertilizer applications per year to stock beds under field conditions or under structures will maintain adequate fertility, plant vigor, and quality. "

If you search in GardenWeb, fertilizer - you'll find some interesting discussions on the topic. It's good to educate oneself on these things so one can make adjustments according to varying conditions including one's wallet and time available.

From Al (Gritty Mix) on another discussion http://forums2.gardenweb.com/discussions/1394063/fertilizer-program-for-containerized-plants-iii?n=150 :

"Production' is when you're pushing a crop to hurry it along to a saleable size. Foliage-Pro markets a lot of their product to commercial growers. 'Maintenance' would be closer to the dosage you would use for most houseplants. When mean temperatures are above 60*, I fertilize weekly with about 4 tsp in 2.5 gallons of water, or about 1.5 tsp/gallon, and I never see any evidence that plants are being pushed too hard. You should be able to use about 1/2 tsp/gallon when mean temps are above 60*, and maybe half that when below 60* with no problems if fertilizing on a 3 of 4 basis - with the understanding that you are watering to beyond saturation so at least 10-15% of the fertigation solution exits the drain, carrying any accumulations of solubles with it. For cacti & succulents, you might want to consider reducing that dosage to 1/4 tsp/gallon."
