How to fertilize Filiformis

Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Filiformis after it doubles in size or once a year—whichever comes first.

Let’s welcome my new #CarnivorousPlants Elina a #SpoonLeavedSundew to my growing family of carnivores. I just got her today and I can already tell she’s gonna shine.

How to propagate this plant? Hey how to propagate this plant

Recently her flower has stalled and darkened in the center. Is this normal? Should I chop it? She has healthy center growth so I don’t think it’s a death bloom. #CapeSundew

Am I a plant killer?? ☹️ these carnivorous plants got all withery and dry. Are they just dormant, or is my curse of plant killing striking again? #imaterribleplantmom
-
I didn’t know Sundew’s would bloom. So I was surprised to see this beauty open today.

My new staghorn sundew. Now to get it over the shock of shipping and getting it healthy again. Everyone meet Messi

My staghorn sundew just came in the mail Saturday and is producing dew already
-
The stag horn again hahaha. Some close up’s of the leaves. The dew is almost like glue. When you pull away from it, it leaves a long strand like pulling away melted cheese

Struggling sundew I’m learning more and more about #CarnivorousPlants and I really want this little #Sundew to thrive. I killed my first one because I let him get too wet and stay that way. I have this guy in succulent soil and water him with distilled water. I let him dry out for a few days and then made a bog again. I’m wondering if I should repot him in the carnivorous soil mix I just got, or just leave him alone. He’s not browning, but no dew yet either. I hate that I can’t figure out this guy! Help!

What can I do for my sundew? Sundew leaves are turning brown, and new leaves aren't growing sticky hairs. I bought the plant about a year ago from California Carnivores. I haven't repotted it, based on their care instructions. Care hasn't changed at all since I got it. It's under a grow light ~12 hours, sits in a small cup of standing water, and all the water I use is collected rain water. I wondered if it might be getting too cold/dry, so I recently thru together a little greenhouse type deal (maybe two weeks ago?) I JUST purchased carnivorous plant fertilizer (also from California Carnivores) and sprayed it once about a week ago. It's a survivor! My new kittens ate all the leaves off it TWICE last winter and it grew back both times. What else can I do? #sundew #carnivorousplants #drosera #help
Filiformis can be challenging to care for, according to some plant parents. Check out the reviews down below to learn from their experiences!
💦 Water Needs
Filiformis is sensitive to dry soil and should be watered frequently. Use our water calculator to personalize watering recommendations to your environment or download Greg for more advanced recommendations for all of your plants.
☀️ Sunlight Needs
Filiformis requires abundant, bright and direct light. Place it less than one foot from a window to ensure it receives enough light to survive 💪. Select your region to see how the current weather in your area affects the placement in your home 🏡.
🐶 🐈 👶 Toxicity
Greg does not have confirmed data on this plant’s toxicity. If you, a family member, or a pet consumes plant material of unknown toxicity, it’s always best to consult a medical professional.
If you or someone else ingested this plant, call Poison Control at US (800) 222-1222. If a pet consumed this plant, contact your veterinarian or the ASPCA at US (888) 426-4435.
🪴 Soil
Filiformis does best in well-draining soil. A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage. Adding a handful of perlite to regular store-bought potting soil should do the trick!
⬆️ ⬇️ Growth Pattern
Filiformis grows vertically and new growth will emerge from the top of the plant.
🌦️ Growing Outdoors
USDA Hardiness Zone
Filiformis can be grown outdoors in USDA Hardiness Zones 7a-8b. Find your local hardiness zone here.
🌱 Propagation
Filiformis can be propagated by division into new individual plants.
- Check to see if there is more than one plant. In some cases they may still be beneath the soil surface. If you feel confident, you may remove the soil to check for baby plantlets below!
- If there are multiple plants growing, unpot the plant and gently tug the plants apart, being careful not to disturb too many of the roots. They may be connected by large root segments which you may need to break to free the plantlet.
- Pot up the new plant in well-draining soil
- Repot the parent plant back into its original pot
🧐 Troubleshooting
When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.
Inspect the soil moisture; too dry or too wet soil can cause problems.
Ensure the plant is getting the right amount of light, as too much or too little can stress it.
Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.
