Carnivorous Plants/dionaea - soil overheating

Question
I grow my venus flytrap outside in full sun. Gets about 8 hours of direct sunlight and i notice the soil tends to heat up, reaching 110 F sometimes. Is there anything i can do to solve this (put white tiny pebbles on it or something?).

Answer
Hello Catalin,

That kind of heat can harm and kill Dionaea. You could place the plant near objects that provide shade for the pot while giving the leaves full sun. Shrubs, other potted plants that can withstand high heat levels, low steps, a stack of bricks, basically anything that would provide insulation by placing your Dionaea among or near such objects can help protect from extreme temperatures while leaving the leaves exposed would help out. You could place a layer of perlite over the soil as an insulation layer since perlite is light and airy. Pebbles tend to trap and radiate heat sicne they are dense. Light, airy substances provide a sheild of material with air layers between in within. Keep the plant hydrated in such high temperatures. I have tomato plants dry up and wither in just a few days in heat levels over 100 degrees. Dionaea would fare worse.

If need be, you could even place a light shade cloth over the plant that would only lessen the imnpact of midday sun while giving it full morning and afternoon sun. In such high temperatures, it becomes a balancing act trying to provide everything the plant needs without harming it.

Expertise

I am capable of answering questions about the most common carnivorous plants found in cultivation. I have no personal experience with Byblis, Drosophyllum, Aldrovanda, and Heliamphora. I have not cultivated gemmae forming pygmy sundews nor tuberous sundews. For information regarding those aforementioned species, I would suggest contacting other experts. I can answer questions regarding most species of Nepenthes, tropical and temperate Drosera, Mexican Pinguicula, Sarracenias, and Dionaea. I have some limited experience with growing Utricularia, Cephalotus, and Darlingtonia.

Experience

I have grown carnivorous plants off and on for about 27 years. I have made the same mistakes and suffered the same mishaps that many growers make as they attempt to separate the myths from the realities of growing these plants. Currently, I am successfully growing a variety of tropical sundews, a Nepenthes, several Venus Flytraps of varying ages, and Sarracenias. I have been successful in stratifying Sarracenia seeds and providing artificial dormancy requirements for my temperate plants when needed.

Education/Credentials
I hold a Master's degree in Educational Psychology. Over my lifetime, I have constantly read books involving the growing conditions of carnivorous plants. I hope to incorporate the educational aspects involved in psychology with teaching other people how to cultivate carnivorous plants.
