We have tested maxsea fertilizer on all of our carnivorous plants and will explain how to get the best results out of it without damaging your plants. Which is pretty hard if 1/4 teaspoon is used per gallon of water.
Plants that benefit from foliar feeding :
Nepenthes - of all the carnivorous plants, nepenthes benefit the most from fertilizing and can tolerate much more than others. If your nepenthes is not catching its own food, simply foliar feed once every 7-10 days or better yet give each pitcher a few squirts of the diluted fertilizer. You can also fertilize the soil directly but this is best done after transplanting or if you want to give it a temporary boost in growth. Not to be overdone and remember if your nepenthes is getting its food from the soil, it will produce less pitchers.
Cephalotus - these are another carnivorous plant that will benefit from the occasional use of fertilizers. Using a spray bottle, give each pitcher a squirt once every 2 weeks and once a month give it a few sprays right down the center of your plant. Growth will be noticeable accelerated
Venus Flytraps - give them a light mist 1-2 per month. Avoid getting fertilizer on the soil as it that can cause mildew unless moss is growing on the surface of your pot. If your soil is compact, you can invert the pot so your flytrap is upside down and foliar feed the traps.
Sarracenia - usually these are gluttonous and continually catch bugs, however during the spring or if small pitchers are forming... We give our sarracenia a liight foliar feed and put a few squirts into any open pitchers. Varieties that are not good at catching bugs will benefit the most from this. We give our Scarlett Belle's a misting every other week.
Sundews - We don't recommend using any fertilizer on sundews... Its better to use flightless fruit flies or freeze dried blood worms to feed them. That being said we have used this on all of our sundews and noticed that one extra diluted feeding every month seems help them grow a bit stronger. If you fertilizer them often, the dew glands will stop producing due and dry up.
Heliamphora - to fertilizer heliamphora, simply foliar feed and occasionally feed the pitchers... A small amount in the pitchers will increase growth and vigor in some varieties.
