There are different ways to grow Sundew, but most of these ways require very little attention from the grower. There is one more method that will require more consideration, however, and that is watering. While this plant requires almost no water, it does require consistent, routine watering. The amount you use will depend on how often you water your Sundew.
Sundew, unlike most other plants, actually prefers a dark, humid environment. If your region does not have heavy rainfall or a lot of humidity, you will probably find that your Sundew will be best in a semi-damp environment. This will help with its dormancy. You may even consider growing carnivorous plants that do not require a lot of moisture. In fact, some varieties of these plants will actually not grow in damp conditions at all, so if your region has heavy rainfall or humidity, you may even consider growing carnivorous plants that are tolerant of these conditions.
If you are considering growing carnivorous plants that need a lot of moisture, consider a member of the Penny Family, Pennyroyal. Pennyroyals are extremely drought tolerant and will grow well even if your region is regularly plagued by heavy rain. These plants also prefer a soil that is slightly acidic. One way to determine if your soil is acidic enough for Pennyroyals is to add a teaspoon of a test brand test into a half pint of water. If the test results read “acidic” in the test solution, then your soil should be slightly acidic.
Most carnivorous plants prefer a sunny location, so the best place to grow sundews that are in need of a lot of moisture is in the shade of a large tree, shrub, or container. In fact, you can grow many varieties of carnivorous plants in containers or small pots. In order to thrive as true carnivores, you must have a self-cleaning mechanism that will keep your plants healthy. This is why you should not over-water your plants. Instead, watering should occur about once per week, although you may want to water more often if your soil is extremely dry.
Contrary to popular belief, dormancy is not a necessary part of the life cycle of most sundews. You can easily turn a plant dormant for up to six months and let it go back to growing like normal. When you do choose to bring your dormancy plants out of their dormancy period, there is only one rule that you need to follow: Remove all dead leaves and petals from the flower. Dead leaves and petals reduce the amount of sunlight that reaches the rest of the plant, and this can seriously affect the quality of the leaves’ color.
To grow sundews that are in need of more moisture, the best option is to give them some supplemental watering, such as water brought from the local water supply or a hose connected to a garden hose. Just make sure you do not get the roots of the plant’s natural environment in contact with the water source or the tap water. Do not worry too much about weeds growing on the flower. If they grow, the Sundew will merely shed them and repopulate the area with new life. Weeding the plant is actually good for the health of its blooms and leaves.
The best way to grow sundews that are in need of more humidity is to provide them with an additional humidifier. A humidifier is very easy to install, and you can find one that is made specifically for plants. You simply follow the instructions on the package instructions, turning the unit on, placing the mist inside the terrarium and setting the control knob to the desired humidity. If your plants do not receive enough humidity, you should consider buying a separate humidifier or spraying the plants with water when the humidity goes below 55%.
To make the most of growing plants from seed, it is important that you know which plants are suitable for your climate. These will determine the climate needs of each species that you plan to grow. For instance, the grow drosera spatulata needs a lot of sun, so place it in an open-air area like a patio, where it will have plenty of light but no direct exposure to the sun. If your area is usually very humid, the grow drosera metadata should be planted in a pot. Both of these species produce white flowers, so they are good starters for a greenhouse.
