Sundews need lots of sunlight, they can take it without any shade cloth provided they are standing in a tray of 1-2cm of rain water. The tray is not a must, but an insurance against drying out – Sundew dies rather quickly if dehydrated. The soil has to be be more soggy than for Nepenthes, coco peat does a good job, but it needs to be replaced, once it looks clayish and the sundew is looking less happy. Many sundews enjoy 50% silica sand (nope, not river/beach sand!) perlite or small pumice in their media. If sundew doesn’t get enough sun it might lack red coloration and be more vulnerable to aphid attack, which can cripple the leaves. For us they get aphids if at all during flowering as the plant gets exhausted and the aphids will disappear thereafter, once the plant recovers. Sundew (except indica, spatulata) doesn’t really like to be watered on the top, or being exposed to rain. If you can, you should try to shelter them, while maintaining high light levels.
Never fertilize sundews, they don’t like it.
What to do after arrival?
Please note that sundew doesn’t look very pretty after mailing, as the glue usually disappears and mixes with the soil. During the first few days keep the plant out of direct sun and well watered. Sundew can not have too much water, but don’t keep the whole pot under water. This works for some Sundews like indica or intermedia, but capensis might rot (once again, if you need more specific info, use Google!). The old leaves might not become pretty again, but the newly grown ones will be. It is fast growing and should be back at full beauty in 1-3 weeks. After a week it can be exposed to more sun.
Sundew likes to catch long legged or large winged insects that mistake the glue drops for water. While it usually goes for fruit fly sized insects, it also catches mosquitos or moths, butterflies and even dragonflies.
