Here are the basics to growing carnivorous plants in your home! It’s pretty easy but it’s not a no-brainer, which is what makes growing these plants so rewarding!
Water: Carnivorous plants need pure mineral free water. This means distilled water, reverse osmosis, or rain water. Tap water tends to have too high of a TDS. If you’re curious to check the TDS of your tap you can buy a cheap TDS meter here, the TDS needs to be under 50 for the water to be safe to use on carnivorous plants.
How much water: You don’t want your soil to dry out, you want to keep the plant wet to damp at all times. The best method of watering plants is the tray method, this way you only have to water about once a week and you don’t disturb the plants by top watering.
Soil: Carnivorous plants grow in nutrient poor mineral free soil. This means peat moss and sand. The best mixes to use when potting your plant is an equal 1:1 peat moss and pumice mix. Sand can be tricky because it can have a lot of “junk” in it that your plants won’t like. If you are able to find horticultural sand sold at garden nurseries, that is your safest option. There cannot be any added fertilizer in the soil, fertilizer will kill your plants. Stay away from anything with the Miracle Gro brand.
Light: Carnivorous plants generally grow in full sun, meaning at least 6 hours of direct sunlight per day. If that isn’t possible, then giving them partial sun which is 4 hours of direct sun per day, along with as much indirect light as you can give them will be best. These plants love the sun, they grow faster and are more healthy when they get the light they need. Sunny windowsills that get 4 hours of direct light should work!
Pots: You should avoid potting your plant in the ground since they require nutrient poor soil. Plastic pots with drainage holes should always be used, clay and terracotta pots can leach minerals into the soil over time. The plastic pot should be at least 4 inches tall, many carnivorous plants have long roots, if the pot isn’t tall enough it stunts the growth of the plant and leaves the plant susceptible to root rot and crown rot. The taller the pot the better!
Dormancy: Most carnivorous plants go dormant and need that dormancy period. Dormancy means the plant will either die back or stop growing during the winter months. It gives them time to recuperate, gain energy and come back stronger and bigger the next year.
Feeding: Carnivorous plants don’t need to eat a lot, you can feed them one bug a month and that’s more than enough nourishment for them. You don’t want to over feed them because that is like over fertilizing a plant. If the plant is outdoor it will have no problem catching its own food. If the plant is grown indoor you can feed it freshly caught bugs or these safe fertilizers. Maxsea is a seaweed based fertilizer safe for spraying on sundew and putting a few drops into pitchers, you can buy it on Amazon here or get a smaller amount of it on my store for cheaper, another option is Osmocote, you place one pellet into a pitcher per month, you can also buy it here on Amazon or in a smaller amount in my online store.
