How big will my Venus flytrap grow?

When fully grown, a mature Venus flytrap will be about 4 or 5 inches in diameter. Each leaf will be between 1 and 3 inches long.

The largest traps will be a maximum size of about 2 inches. So, unfortunately, you won’t be able to feed your little brother to your Venus flytrap even when it is fully grown.

How often should I feed my Venus flytrap?

If you grow your Venus flytrap plants outside, the answer to your question is never. They will catch all the food they need on their own. I was skeptical of this myself when I started growing Venus flytraps but, in fact, it is rare to see an open trap! They are very good at luring and capturing their own food.

If you grow your Venus flytrap inside, or if you just can’t stand the temptation, feeding them a couple of insects a month would be sufficient…after all, it is so much fun to watch those traps slam closed! Be sure to feed them live insects or, if you feed them dead insects, you’ll have to spend a little extra time massaging the sides of the trap to ensure digestion begins.

Under no circumstances should you feed your Venus flytrap any kind of people food. This will be very harmful to the plant and kill the trap that you feed the food to. Hamburger, pork, chicken, pasta, potato chips, avocado are all not on the menu for Venus flytraps. Venus flytraps are insectivorous plants, which means they only eat insects. So, feel free to feed them ants, spiders, earwigs, flies, or any other creepy-crawly that you can catch!

When flytraps are dormant, there is no need to feed them. In fact, there is never really a dire need to feed Venus flytraps, as they are more than capable of photosynthesizing for their own energy just like other plants. And during the winter months, flytraps drop most of their larger leaves that are big enough to catch prey, and the traps they retain normally become unresponsive or very slow to respond. In nature, there aren’t many insects out and about during the winter, so flytraps have evolved to not waste energy trying to catch something that isn’t there!

I recently got a Venus flytrap in the mail. Some of the leaves were black when I got it and now more are turning black. What should I do?

It’s perfectly normal for older leaves to begin to turn brown and black after transplanting. It’s easier for the plant to re-establish itself if it has fewer leaves to support while its roots are becoming accustomed to the new medium and growing conditions.

Most likely your new plant is just suffering from any climate change it’s endured during transit. Don’t worry! Just trim off any parts that turn black and it should begin showing new growth soon.

I just received my Venus Fly Trap but in transit, all the leaves closed up. When will they reopen?

When traps are triggered without any live captured in them, they will open in a day or two. The warmer the Venus flytrap plant is kept, the sooner it will reopen. There is no concern about the plant dying. We almost always trigger all the traps on our plants when they are repotted and always recover just fine.

What should I feed my Venus flytrap?

Venus flytraps can benefit from being fed regularly. While feeding is not required, Venus flytraps will grow more quickly and have overall better general health if they are allowed to catch insects or fed on a regular basis. If you are growing your flytrap indoors or in a location without many insects, you may choose to feed your Venus flytrap to help it grow more quickly and be healthier.

DO NOT feed your Venus Fly Trap anything other than insects. Under no circumstances should a Venus Fly Trap be fed something that it couldn’t catch on its own in nature. First of all, this will likely make the trap turn black and die if it actually forms a seal around the meat and starts to digest it. Continually feeding a Venus Fly Trap stuff like chicken, beef or pork could actually end up killing the plant.

Secondly, it is unlikely that the trap will even seal completely to begin the digestion process because it requires live prey on the inside of the trap struggling to signal the trap to seal.

The only things you should feed your Venus flytraps are insects. Any kind of insect is fine. Flies, beetles, spiders, wasps, earwigs, and pretty much anything that crawls or flies and is an insect is good.

The reality is that you don’t actually need to feed your Venus Fly Trap anything other than lots of sunlight. If you grow it outside, it will catch all the food it needs on its own and get plenty of sun.

Where should I keep my Venus flytrap?

The best place to grow Venus flytraps is outside, when possible. It is possible to grow Venus flytraps outside throughout most of the world during the summer months. Many Venus flytrap growers move their plants outside as soon as the threat of frosts has passed and leave them outside until freezing temperatures return again in late fall.

If growing your Venus flytrap outside isn’t an option, then some other choices are a greenhouse, a very sunny windowsill , under a grow light, or under one our LED Terrariums designed specifically for Venus Fly Traps.
