How to Grow Carnivorous Plants in Your Backyard
Growing carnivorous plants is an exciting and unusual gardening project. With a little bit of knowledge, I can successfully raise these fascinating plants right in my own backyard. Here is a comprehensive guide to get me started.
Choosing Carnivorous Plants to Grow
There are over 600 species of carnivorous plants, offering a wide range of options to grow. Here are some of the most popular varieties that can thrive outdoors:
The Venus flytrap (Dionaea muscipula) is arguably the most famous carnivorous plant. This small plant features distinctive snap traps that close quickly when insects land on trigger hairs inside. Venus flytraps need a dormancy period and do best in bright, direct sunlight.
Pitcher plants like the purple pitcher plant (Sarracenia purpurea) capture prey in specialized leaves shaped like pitchers. Insects are attracted by nectar and fall into the pitcher, where they drown in the accumulated rainwater. Pitchers flourish in bright light and constantly moist soil.
Sundews (Drosera species) have leaves covered in sticky tentacles that trap insects when they land. As the insect struggles, the leaves slowly curl around it and digest it. Sundews enjoy full sun and moist, acidic soil.
Butterworts (Pinguicula species) have leaves coated in a sticky mucus that traps small insects like gnats. They are more subtle in their carnivorous mechanisms than other varieties. Butterworts prefer boggy conditions and filtered sunlight.
Providing the Right Growing Conditions
Carnivorous plants require specific conditions to thrive. Here are some key factors to provide in my backyard:
Most carnivorous plants grow best in full sun, which means at least 6 hours of direct sunlight per day. I’ll need to choose a sunny location in my yard.
The soil should be moist but not excessively wet. I can create the right boggy conditions by using a mix of peat moss and sand. Gravel or clay pots will improve drainage.
Carnivorous plants like soil with a pH between 4-6, so I’ll need to test and amend my backyard soil to lower the pH if needed. Sphagnum peat moss helps acidify soil.
I should avoid tap water, which contains minerals that can build up in the soil over time. Rainwater or distilled water are better options for carnivorous plants.
Feeding My Plants
Although carnivorous plants can trap insects, I may need to supplement their diet occasionally:
Place a small crushed up eggshell or calcium tablet in the soil 1-2 times per month during the growing season for extra nutrients.
Spray diluted liquid fertilizer on the leaves every 2-3 weeks to provide nitrogen.
Trap insects like fruit flies or small spiders inside the traps to give the plant live prey. Just don’t overfeed them!
Caring for Carnivorous Plants
Here are some tips to keep my carnivorous plants healthy:
Keep the soil moist, but not waterlogged. Remove standing water in the trays.
In winter, most varieties will need 3-4 months of dormancy at temperatures around 40°F. I can bring them indoors or insulate outdoor plants.
Repot every 2-3 years in fresh soil, being careful not to damage the delicate roots.
Prune off any dead, diseased, or damaged growth to keep plants looking their best.
Propagate by dividing mature plants or taking cuttings in spring or summer.
With proper siting, soil, water, and care, I can enjoy these unusual and fascinating plants for many years to come right in my own backyard. It’s sure to be an interesting conversation piece whenever I have visitors over!
