Drosera madagascariensis is a robust stem-forming species with a clearly visible stem, which stands upright in the case of younger plants and either uses its leaves to anchor itself to surrounding vegetation as it matures or bends over and forms a scrambling stem.
Frequent watering of your sundews planted in containers will help keep the soil moist. But use distilled water or collected rainwater, as many potted plants with special soil needs, like the sundew, will not tolerate a high level of minerals which may be found in tap water or spring water.
Sundew plants do best in full sun. If growing indoors, a sunny window is a good location. The plants will also thrive fairly well with indirect sunlight or partial sun, as long as they get at least several hours of sunlight per day.
If growing in pots, use a mix of vermiculite and/or perlite and peat moss, with a bit of composted potting soil added in too. This soil mixture will hold moisture well and provide the acidity preferred by sundew plants. If you have soggy soil in your yard and plenty of warm temperatures in the growing season, you may be able to successfully grow them in your yard. Till the soil well before planting and add plenty of sphagnum peat moss to increase acidity.
True to their name, these plants like a warm, moist and humid environment. Make sure they are not exposed outside to temperatures below 50 degrees, and if temperatures are below 70 degrees for more than a few days, you may want to bring them indoors.
