One way to keep your Bladderwort adequately moistened is to grow it in a pot with good drainage holes and in a plastic dish or tray that will allow you to fill it to about a third to half an inch of water. This will naturally draw water from the pot to the roots as the soil dries.Don’t let the dish dry out completely and adjust how much you add based on how quickly the plant draws the water into its roots. Pots made from hardened clay called terra cotta are not suitable for growing the Bladderwort unless you place the pot inside a second, bigger pot. The terra cotta will allow water to seep through and filter out dissolved solids. Put the water only in the second, outer pot. The most important thing in watering your Bladderwort adequately is the mineral content of the water you use. Collect rainwater if you can for your Bladderwort. It is the safest of any water to use on plants. Distilled water and water from a reverse osmosis system are good alternatives. You can use purified water which also works but has some minerals in it but in a range the Bladderwort tolerate. Tap water with lower than 50 parts per million of total dissolved solids is safe. You can buy a meter to measure that for just a little money. You’ll want to fill your watering device 24 hours before you use it to give the chlorine a chance to off-gas from the water.

Symptoms of an overwatered Bladderwort are brown spots forming on the undersides of leaves, white mold developing in the soil, and a general wilted look. The wilted look comes from the plant’s inability to draw water into the stem. Overwatering can cause root rot. If it’s rotted, and smells bad, you’ll want to remove the plant from its soil, rinse it with distilled water, cut away the rotted roots and affected leaves, rinse it again with distilled water, and replant in new soil. The leaves of an underwatered plant will become brittle. Cut away affected leaves, make sure the soil is damp, and mist the leaves. For underwatered Bladderwort, the plant will gradually recover by resuming watering as soon as possible, but due to root damage, yellow leaves will dry out in the short term.

Tray method is the most common way of watering insectivorous plants. Potting Bladderwort in something with several drainage holes and placing that in a dish or tray filled about one-third with water will allow the plant to naturally draw water up as the soil dries. Add water promptly after the water level drops. Don’t let the dish dry out completely. This will give you a better sense of how often the plants are watered. The Bladderwort is native to humid environment, so you’ll need to strike the right balance between watering to the point of developing root rot and letting the soil dry out . During the active seasons – spring to autumn – don’t let the soil dry out. Water your Bladderwort 2-3 times per week in spring and fall, and more frequent watering in summer to keep the soil mosit. Bladderwort goes dormant when during the winter and early spring. If you care for one the same way that you care for it during its active season, you will likely kill it. You’ll need to cut back on the amount that you water it. Try letting some of the soil dry out as well as letting the water level in the tray dry out for a few days before adding more. If you live where the air is naturally dry, you may find that misting it above and beyond what you feed it is necessary to replicate its natural humid growing conditions. It works best to do this in the morning. Proper water spraying is very necessary for areas with a dry environment.

Bladderwort normally lives in humid environment and are prized as houseplants because they one of a handful of carnivorous plants. Successfully keeping one alive will require that you need to replicate its native growing conditions. Maintaining high humidity levels is key to growing a thriving Bladderwort. The places these plants naturally thrive are high in humidity and low in nutrients. If you live in a place with naturally high humidity, you can grow them outdoors in a bog garden. A bog garden is a unique way to present plants that require lots of humidity together. Most people grow them as houseplants. Use a pot that will retain moisture to cut down on the number of waterings you need to do. Plastic is much better for this than terra cotta. A self-watering pot works best of all. As an insectivorous plant, the tray method is the most effective way to replenish water. Make sure that the water level in the tray pots spreads over the small hole at the bottom. Add water in time before the water level drops and the trays dry out. The amount of water added is the amount of water the plants need to keep the pots from drying out, so your Bladderwort can keep growing well.

Bladderwort growns indoor will generally requires less water because they receive less sunlight. The more light it receives, the more water it’ll require to grow. Adequate light and water are the basis for keeping them healthy. But, you’ll still want to maintain a humid environment for an indoor plant. A good option for maintaining humid conditions is to grow them in a terrarium or as part of a plant display in an aquarium. The encased sides will keep vital humid air from escaping. Just make sure you maintain good circulation.

You can prune your Bladderwort any time you notice dead, diseased, or damaged leaves during the growing season. Once you notice such a leave, locate an unwanted leaf, then follow its stem all the way to the bottom of petiole. Removing dead stems will increase the light and ventilation of the plant and help it to grow. You can cut its stem just above the soil’s surface to remove it. Such pruning can take place as needed during spring and summer. Also, this plant can bloom any time between spring and fall, and some gardeners choose to remove flower buds before they have a chance to open. Removing unopened flower buds allows this plant to focus most of its growing energy on its beautiful leaves. However, pruning in this manner does not necessarily influence the plant’s overall health. Cutting back should be done late in the winter to early spring. Ideally, you should wait until you see new basal growth before you cut off the dead and dried winter parts, to about 6 inches from the ground.

Pruning the Bladderwort is as easy as waiting until you notice dead or damaged leaves on your plant. When you recognize these leaves, equip yourself with a pair of sharp and sterile hand pruning shears. Hand pruning shears will work best as larger tools like loppers will not be well suited to the precise cuts you need to make. Once you have a proper set of pruning tools, locate an unwanted leaf, then follow its stem all the way to the bottom of petiole. Removing dead stems will increase the light and ventilation of the plant and help it to grow. Cut the stem just above where it exits the soil to remove it entirely. If you wish to stop this plant from flowering, you can use the same pruning shears to remove any buds before they open. Finally, you may prefer to just trim off dead or damaged portions of the plant, including deadheading spent flowers, to keep it looking its best. This can be done at any time of year. Diseased or damaged stems should be cut right at the soil line and removed completely. Blooms should be cut off just below the flower head. Cutting back should be done late in the winter to early spring. Ideally, you should wait until you see new basal growth before you cut off the dead and dried winter parts to about 6 inches from the ground.

All that is required of you once you have pruned your Bladderwort is to clean up. Once you have pruned, deadheaded, or cut back your Bladderwort, gather the bits you have cut off and discard them. If there are any diseased parts of the plant that you have pruned away, do not discard them with the rest of the pruned pieces. Diseased foliage should be disposed of. When watering after pruning, be careful not to touch the wound to prevent fungus from infecting the plant through the fresh wound. Placing Bladderwort in a well-ventilated location will also help the wound to dry out and heal in time.

For your major pruning, use sharp pruning sheers that will make clean cuts to avoid damaging your plants. As you are pruning your Bladderwort, step back occasionally to check the appearance of the plant to make sure it has the shape you want and that you are pruning it symmetricaly. It is recommended that gloves and safety glasses be worn while pruning Bladderwort.

Pruning is an important part of plant care and maintenance. Different plants have different pruning requirements. Some plants may need little to no pruning, while others may require more specific attention. Most plants should be pruned to remove damaged or unhealthy foliage. Other plants may be pruned to control their shape and size. Pruning may even be done to remove the flower heads of plants and stop them from self-seeding. Although some gardeners may find pruning a tedious task, it is a necessary evil and is an essential part of keeping your plants happy and healthy.

Bladderwort thrives best in natural, direct, outdoor sunlight. Exposure to full natural sunlight allows it to grow healthy and to its full size and display attractive coloration; depending on the species, these can be different shades of reds, crimson, pink, or purplish. However, even with the full sun preference, Bladderwort should ideally be protected from the harshest sun - the summer mid-afternoon sun. Even plants adapted to full sunlight can suffer when exposed to this sun radiation level. That is why you should be able to move your plants or install something that will provide partial, dappled shade during this part of the day. An important thing to remember is that evaporation increases significantly in the direct sun. Since Bladderwort is wetland plant, maintaining constant moisture is mandatory. Thus, pay attention to the water levels in the water trays during warm days and refill regularly.

If Bladderwort receives too little sunlight, below the required daily minimum, the first thing you’ll notice is discoloration. The plants will first become purely green, losing red, orange, or pinkish colors, and then become even duller. Those that produce moist and sticky insect-attracting sap may have trouble making these substances. In the long run, the Bladderwort will grow poorly in low light, the new growth will be weak, and they may have a shorter lifespan.

Young and mature plants of Bladderwort have pretty much the same lighting requirements. However, for non-tropical species, there is a seasonal difference in lighting needs, especially concerning the duration of light. During the winter rest, 10-12 hours of indirect light per day is ideal. However, a dormant Bladderwort should not receive more than this. Daylight lasting 14-16 hours would trick the plant into coming out of dormancy, which would have overall negative effects. Thus, make sure that your Bladderwort have a sufficient period of darkness during the winter.

Four to six hours of direct sun and six to eight (or more) hours of partial sun per day is an excellent measure for most Bladderwort species. Ideally, the direct exposure should start in the morning and last until the afternoon in the summer, when the plants should get some cover from the most intense summer afternoon sun. Late afternoon sun exposure is perfectly fine.

This intense need for sunlight might seem unusual for a wetland plant. However, remember that most of the Bladderwort foliage is modified to attract and digest insects. Thus, less leaf surface is available for photosynthesis. Also, these plants come from warm, subtropical, and tropical climates and ecosystems with high, near-equator sun exposure.

Suppose you have bought your Bladderwort from a supermarket or another type of non-specialized store. In that case, the chances are that they have been receiving low or inappropriate artificial light and haven’t been adjusted to direct sunlight. In this case, the plant needs to be hardened off before exposure to real, direct sunlight. Start by gradually exposing your plants to sunlight, first keeping them in bright indirect light, then slowly increasing their exposure to direct light, about an hour per day. If you cannot provide the right natural light conditions for your Bladderwort, the last resort is to grow them under artificial lighting. Although these plants are supposed to thrive under standard fluorescent lamps that emit cooler light, it may be safer to opt for specialized plant lights. Keep in mind that indoor plants are more susceptible to diseases.

The best position for growing Bladderwort is an outdoor sunny spot. The outdoor position will ensure not only the best quality of light but also make the plant more resilient against infections. The UV rays from sunlight, along with the wind and precipitation exposure, will kill most fungal pathogens. If you need to grow your plant indoors, the second best position is a sunny window sill face to a south-facing window (east and west are also an option, as long as the plants receive 4+ hours of light).

There is an ideal temperature range that makes Bladderwort feel at home. Under these temperature conditions, it's unlikely that you’ll have any issues with cold or hot damage to the foliage, but changing leaf colors can absolutely be a sign that Bladderwort isn’t happy. Try to keep your Bladderwort well within its preferred range of 70-85℉(21-30℃), but don’t panic if the temperature creeps up past 85℉(30℃) during the day or down to 70℉(21℃) at night.

If your Bladderwort happens to be planted outside, then there’s not much you can do to try to move it indoors. However, you can certainly provide cover in ways that will help it survive any extreme temperatures that may arise unexpectedly. For instance, you can always use a few stakes and some cloth to put together a shade tent that will block out much of the sun’s intense heat from direct sunlight exposure. Similarly, Bladderwort can be protected from the extreme cold and especially chilly winds by building a small greenhouse around the plant, which will create a greenhouse effect and warm the plant up. This can be done using garden stakes and any sort of clear or translucent plastic you may have around; if you have greenhouse plastic such as polycarbonate laying around, this works perfectly. Remove the greenhouse once temperatures warm up to 40℉(10℃) at night.

Generally speaking, Bladderwort needs to stay within its preferred temperature range all year long. However, that doesn’t mean that care should stay the same all year long. During the warmest months of the year, Bladderwort will need a little extra shade and a bit more of a breeze to help it cope with the hottest days. On the other hand, it may need to be moved away from chilly windows and doors during the cooler months in climates where temperatures drop below 40℉(10℃) at any point in the year.

Keeping your Bladderwort at the right temperature can be fairly simple. Depending on where you grow it, Bladderwort can be fairly easy to accommodate. For indoor growing, you can easily move the plant to different locations within your indoor space that best meet its temperature requirements. Avoid placing it near air conditioning vents, heaters, doors that open frequently, or drafty windows. It is a little more difficult to control the temperature around your Bladderwort if it’s grown outside. Of course, if it’s planted in a pot, you can simply bring it indoors when the temperatures outside get too hot or too cold for Bladderwort, but otherwise, you may need to take different measures to protect it from extreme heat or cold that may damage it irreversibly. Try placing Bladderwort under cover to protect from both the harsh sun that can overheat it and any cold wind that could be potentially deadly for your plant.
