In case your wondering, I'm new to the forum. I purchased a Snake Plant 3 months ago and it's doing well (thanks to this forum for answering some important questions about care - specifically about watering). I'm watering it about every 3 weeks when the soil feels dry and my Water Meter reads 3. Now, it's spring and time to fertilize. I've read that the Miracle-Gro spikes are not good for snake plants and I should use Miracle-Gro for Succulents. I've ordered some and now I need to know the proper dosage. It's in a 10" pot and I'm attaching an image of the plant so you can see the size (about 46" tall). I'd appreciate any input.

Unless your Snake Plant is very close to a sunny window, it will need little or no fertilizer at all. In low light, this plant uses little water and few nutrients.

Fertilizer spikes do tend to create mineral "hot spots" where they are inserted. Using a water-soluble fertilizer is easier to manage. If you do use it, dilute it to half strength and apply it a few times per year at most.

Thanks Will C. I'll be very careful with the fertilizer. I keep the plant in the kitchen but it doesn't get very bright. Your comments are very well appreciated.

If your Snake Plant is not in good light, then skip the fertilizer altogether. There is a greater risk of burning tender roots with excess nutrients.
