Plant as soon as possible

Ideal Planting Conditions for Venus Flytrap

We ship only small first season bulbs and green plants which we grow from our tissue cultured clones.  Bulbs, if visible, are small, just beginning to form.

Soil: 100% peat.  The more coarse peats are best as they have better aeration.

Fertilizer: none at planting

Water: low salt, e.g. EC <= 0.1

Planting Depth: Plant with roots down. Bury half of the green leaves below soil level, and leave the other half of the leaf surface above the soil. Visible leaves will die back as new leaves emerge from the bulb.  Bulbs are really small creeping rhizomes. Bury all white parts of the bulb (lower leaf). If any white colored root/bulb/leaves are left above the soil, the plant will dry out and die.  New roots will appear as white bumps and will emerge from the newest part of the bulb. Old roots are brown in color, with light yellow-white tips.  Rarely do these roots survive transplanting.

If bulbs have no green leaves showing, plant and cover them with 1/4″ of peat.  Do not plant too deeply.  Must be planted shallowly.

Water at once. Never allow these plants to dry out completely. These are swamp plants and they do not survive low humidity nor dry soil.

Ideal Growing Conditions for Venus Flytrap

Temperature: Nights 70-80f, Days 80f-100f forces growth. Nights 40f with days <60f for 30 days satisfies dormancy requirement. Refrigeration may be used in lieu of in situ chilling.  Plants must receive a 30-60 day chilling period once a year in order to trigger normal growth in the Spring.

Humidity: 55-85%.  Keep leaf surfaces dry to avoid fungal diseases. Do not mist.

Light - Day Length:  Long Days encourage tall growth.  Short days encourage horizontal growth and smaller traps.

Light – Intensity:  <1000 ft candles promotes soft all green growth.  3000-5000 ft candles promotes red coloration of inner trap surfaces, and larger bulb growth.  Larger bulbs tend to throw larger traps.

Fertilizer:  100ppm balanced feed once a month, April through September when plants are in active growth.

Watering: Keep moist. Venus Flytraps need to dry slightly between watering, but must never be allowed to dry completely.

Ideal Timing:  Bulbs and small plants potted up in February through March will be just leaving winter dormancy. Growth rates tend to be fastest during the lengthening days of Spring with plants often producing one new leaf per week.    Bulbs planted in Summer months grow rapidly as well until about September when leaf production slows and the plants begin to enter winter dormancy.

Finishing Times for Venus Flytrap

8-12 weeks in Spring and Summer will yield a plant with 5 leaves and traps.

How to Grow Large Traps:

Trap sizes vary tremendously from plant to plant, even within a given clone.

Low light levels, e.g. <900 ft candles,  may promote soft growth and larger traps.

Older plants tend to have larger traps, e.g. older than 2 winters.

Cold dormancy also tends to promote larger traps. Largest traps emerge from bulbs/plants which have had 1 or 2 winter periods of dormancy.  If traps are still small in June, one trick to get larger traps is to place the plants with small traps in 40f nights, 40f days (refrigerate) to initiate an out of season dormancy for 30 days.  Moving the plants back into 70f nights and 85-95f days  in Summer will trigger rapid growth, and almost always with larger traps.
