Let's look at some unfurled leaves, coz lately my philodendrons are going crazy This first photo is of my Philodendron 'Red Congo Dwarf Mint'. This is a typical unfurling leaf of Philodendron erubescens and similar species. Reddish leaf, no sheath. This next photo is of my Philodendron 'Paraiso Verde', which essentially grows a new leaf every week. You'll notice with many climbing philodendrons that they will have a sheath as they grow from which the leaf emerges. In my Paraiso Verde at least, the sheath [sheath A] will not be disposed of until the next sheath [sheath B] starts to grow. After the leaf from sheath B starts too emerge will then sheath A be disposed of. You can see what i mean from this Philodendron 'Florida Beauty'. The sheath you see below the new growth is starting to become extremely loose. In some time, it'll be disposed of. You may however also notice the sheath here is mostly unraveled already—the sheath on my Paraiso Verde has yet to unravel, as i notice the sheath on my Paraiso Verde only fully unravels when the leaf has grown out of the sheath. On this next example of my Philodendron gloriosum 'Snow Leopard', the sheath is already dying as the leaf emerges. This is interesting as the sheath appears to only protect the growth when it initially emerges—once large enough, but still not open, the sheath is already of no significance to the plant. You'll usually notice high-degree of damage on plants like these in the wild. This last one is of my Philodendron tortum. In the photo you might notice, its similar to that to my 'Paraiso Verde' or my 'Florida Beauty'. The difference is that this leaf emerges from the side, rather than from the top. I do find this interesting, as it does leave the leaf more exposed to damage, but does mean the leaf can unravel faster. Mine is already starting to loosen up. All of this is based on what i observed coz of how my ADHD picks up the most random things and decides to info-dump with almost every social interaction, so i might be wrong on some of this. #HappyPlants #PlantsMakePeopleHappy #PlantAddict #NewGrowth #PlantTherapy #Philodendron #PhiloFlock #RarePlants #rarephilodendrons #PlantInfo #ADHDPLANTLOVERS

Can we have a discussion on tap water? Common belief is that, the chlorines [and chloramines] in tap water will kill plants. If that's so, all my plants would've died by now. I'm using straight from the tap, average levels abt 2.27ppm with range from 1.34—2.86ppm. I water EVERYTHING with this. Alocasia, seedlings, Philos, Monstera, orchids, Nepenthes, cactus, Anthurium even the random cups of aquatic plants i have. Truth is, WHO's guidelines of 5ppm in chlorine levels is far below the tolerable levels of 100—150ppm for most ornamentals. Sure, plants like Begonia or Geraniums, their growth slows at 2ppm [doesn't mean that they die], but overall 5ppm is quite okay. In the US it's only 4ppm at most too. Some chlorine is needed by plants for basic functions, like nutrient uptake or leaf turgidity. It is important to understand that, the chlorine itself won't kill your plants, unless allowed to build up [by then it's probably repot time for healthy plants]. What DOES kill plants is the overdose of heavy metals in many tap water. Mainly the ones to look out for are Cadmium [Cd], Chromium [Cr], Lead [Pb], Arsenic [Ar], Mercury [Hg], Copper [Cu], Iron [Fe], Manganese [Mn], Molybdenum [Mo], Nickel [Ni] and Zinc [Zn]. The last 6 are micro elements that are needed in small quantities by plants, take note of the following levels at which these elements are required: • Cu: 5-20ppm • Fe: [quite varied, the internet is very divided over this. Some say a range of 2-3ppm, some >4.5-5ppm, some 10-20ppm, even down to 0.1-0.5ppm. Really, just monitor for iron deficiency or overdose symptoms] • Mn: 15-20ppm • Mo: 0.1-1ppm • Ni: [again, very divided. There's as low as 0.03-0.06ppm to 100ppm. But really, nickel isn't normally a huge concern] • Zn: 0.5-10ppm The remaining [Cd, Cr, Pb, Ar, Hg] should be close to zero anyways, it's WHO's guidelines. Anyways if the levels in your tap water for these elements are too high, you may have problems. Same with well water. Should you have these issues, use a distiller, RO unit or water conditioner that removes heavy metals [such as API Aqua Essential or Seachem Prime]. These are usually able to be bought by the gallon online, and will last you for a long time. Also, a word on water softeners. If you have water softeners installed, PLEASE use a distiller or RO unit. Water softeners utilises Sodium or Potassium compounds to bind with hard minerals. These ions can build up in soil, leading to dehydration as they'll interfere with the plant's ability to take up water and other nutrients. #HappyPlants #PlantsMakePeopleHappy #PlantAddict #PlantTherapy #WateringWednesday #PlantLove #plantproper #TropicalPlants #AquaticPlants #AlocasiaAddicts #Alocasia #Philodendron #PhiloFlock #Monstera #MonsteraMob #OrchidLovers #OrchidOrg #Orchid #Nepenthes #CarnivorousPlants #CarnivorousClub #CactusClique #Cactus #Cacti #cacticollect #SucculentSquad #SucculentLove #Succulents #Succulent #SuccerForSucculents #Anthurium #GregGang #Greggers #GregFam #PlantInfo #PlantFactNOW
