How to grow
The information provided here is based on my own experience; the opinions/experiences of others may differ.
Sarracenia
- Soil: A mixture of natural peat and perlite, in a ratio of approximately 1:1.
- Water: Rainwater, RO water, deionized water, distilled water
- Light: Full sun; the more light, the better.
- Temperature: They do not require special protection; in case of persistent severe frosts, it is worth providing a more protected place; in summer, during the heatwave, we should check the water more carefully to ensure that there is a sufficient amount under them.
- Wintering: They are demanding; keep their soil moist, they can stand in shallow water. We protect them from freezing winds: it is worth covering them during this period if they are outdoors. If the traps are gradually dried out; in a greenhouse, it is worth cutting them off, because if there is no proper air circulation, they can be a source of various fungal diseases; it is worth leaving them outdoors, because they provide protection against the cold.
Venus flytrap
- Soil: A mixture of natural peat and perlite, in a ratio of about 1:1.
- Water: Rainwater, RO water, deionized water, distilled water
- Light: Full sun; the more light, the better.
- Temperature: A little more protection than the sarracenias have in winter.
- Wintering: They are demanding; keep their soil moist, they can stand in shallow water. Protect them from freezing winds: it is worth covering them during this period if they are outdoors.
Cephalotus follicularis
- Soil: A mixture of natural peat and perlite and quartz sand, in a ratio of approximately 2:1:1.
- Water: Rainwater, RO water, deionized water, distilled water
- Light: Full sun; the more light, the better.
- Temperature: No special protection required year-round; requires attention in winter.
- Wintering: Growth slows or even stops in winter; can survive short, light frosts, can resprout from roots; does not tolerate severe frosts.
Drosera
- Soil: A mixture of natural peat and perlite, in a ratio of about 1:1. Some species prefer a medium enriched with quartz sand.
- Water: Rainwater, RO water, deionized water, distilled water
- Light: Full sun / partly sunny
- Temperature: No special protection is required during the year; non-temperate species should be taken care of in winter; tropical and subtropical species should be moved to a protected location.
- Wintering: Temperate species produce winter buds (hibernacula) and dry their leaves. Some species have a rest period in summer. Tropical species do not have a wintering period. Pygmy sundews need room temperature and little watering in winter (their gemmae production period)
Utricularia
- Soil: Terrestrials are not picky, they thrive in both quartz sand and peat. For epiphytic plants, a mixture of natural peat, perlite, and live sphagnum moss can work.
- Water: Rainwater, RO water, deionized water, distilled water
- Light: They prefer bright, diffused light
- Temperature: They do not require special protection during the year; they should be moved to a protected place in winter. Except for U. subulata, it cannot be destroyed even with napalm.
- Wintering: In a room at room temperature, do not let them dry out.
Nepenthes
- Soil: A mixture of sphagnum moss, perlite, and pine bark chips. The key is to make sure it has good drainage.
- Water: Rainwater, RO water, deionized water, distilled water. DO NOT let water stand under it!
- Light: They like bright, diffused light, direct sunlight can burn the leaves
- Temperature: All pitchers require temperature fluctuations between day and night. The temperature itself depends on the variety, lowland ones prefer higher ranges, highland and ultra-highland ones prefer cooler, cold temperatures. Intermediates naturally move between these. The tolerance of hybrids can be estimated based on the parents. I can recommend this page as an aid: Ultimate Nepenthes Guide
- Wintering: In a room, at room temperature, do not let them dry out, but do not let them stand in water. They do not require a rest period.
