Hello,

I am really hoping somebody would be so kind to help me save my plants as ive lost about 30 this week and I really, really need to save my two big pride and joys :(

About two weeks ago I noticed and commenced treatment for spider mites that in hindsight must have been around for at least 6 months! I used all sorts of products from rose spray, to eco spray, to neem oil, to white oil and finally pyrethrum and a big wash of all plants and roots and a repot in new soil.

That issue seems to be under control. The very day I celebrated my success, I noticed something else happening to my plants very quickly.

black, or very dark brown, strange spots and dots appeared almost overnight on everything! any new growth coming through went black on the tip and stopped growing. Some plants had smudgy brown stains on the underside of leaves and some have what I can describe as spots, the size of half a pea.

I had a new plant somewhat isolating near a window and overnight a black spot with a white centre.

I have a brand new Huge bushy fiddle leaf that was isolated in a closed room that, after 3 days of being in my house, has developed small black dots the size of a pinhead, perfectly round, on most leaves maybe 3-8 per leaf. some dots have a tiny white centre.

I noticed on the window some mould and im strongly thinking its from this? can that happen?

ive banished all my smaller plants to the shed and my flf and my beautiful big philodendron are now outside undercover.

ive so far sprayed with a bi-carb/water/ seaweed mix and today Yates fungicide which is sulphur

does anybody have any guidance for me please? I dont have a photo to upload which is not helpful, I will try to add one!! black circle dots, white (sometimes) centre!!!!!

Hello,

I only have these photos that I took earlier today.
The flf is in the pot it came in (purchased 5 days ago) and is in a soil heavy with peat moss that was just damp when I got it and I have given it a tiny splash of rain water since then and dont plan on watering it very much at all given the peat moss and the weather. The pothos is in a fast draining sandy soil and the philo and lily in a pretty standard indoor potting mix which I plan to be very cautious about watering until especially the philo grows into his pot.

Im esspecially confused about the flf as it was totally quarantined from other plants so it simply must be a result of the damp weather we have had lately, coinciding with mould growing on my windows in a very short amount of time... but can household mould do that to the plant? or maybe my other plants had a fungus which was present in the house? I had a monstera 2 weeks ago become very suddenly black/brown smudged and sick looking

I appreciate your help so much!

*the neon pothos you see was a brand new Bunnings purchase who died almost within the day in my house from those spots, the pot its in is totally wrong

oh and the white stuff is sulphur/ Yates fungicide which seems to have killed the dots (by my eye..they look drier) the pics on flf and others are after the sulphur treatment. yesterday they were more black and 'alive' looking

You need a little more dry time between waterings and allow the dry cycles to extend a little longer. Excess water uptake can cause veins at the edges to burst, which leads to browning.

A lot of what I see are symptoms of Helicopter gardening. Try doing less mothering and give treatments time to work. 5 days is WAAAAAY to soon for anything you've done to affect your FLF. Same goes for the Pothos. Short of microwaving, baking or soaking in something really caustic, there is no way anyone can kill a Pothos in a day.

Cut yourself some slack, take some deep breaths and relax a bit.
