Monstera Albo Borsigiana Disease leaf underside gets shady brown?!

[Mark_Enschuh]

Hi everybody,

i reall need your help.
I got this beautiful new Monstera Variegata... Since I got it it makes problems... I repotted it because the soil was not really optimal.
Most of the plant seems really healthy but 3 leafs got these brown spots, at first the white parts on some leafs. Then I noticed kind of a brown shade on the white leafs and after some time especially on the lower side. Then I noticed on a really healthy green leaf this complete brown shade and its kind of sticky but there are not thrips.
I have no IDEA and iam really concerned.
PLEASE HELP ME AND MY BEAUTIFUL ALBO

Hello Mark, and welcome. Before we can find out about your plant problem we need to know a few more things. Have you put your plant in a pot with good drainage holes? Was there any sign of a problem when you bought it. Where did you buy it - was it in a store or a good garden centre? What was wrong with the pot and compost you bought it in - and what kind of compost have you put it in now?

Yes there is definetly good moisture so no water problems! No just brown leaf tips, i bought it on ebay. The old pot was very large and a lot of fine densely compressed earth so I made a new with more air in it. i used lechuza soil with normal palms earth and expanded clay

I dont think its the soil... I think its more kind of bacterial or fungicid

I`m afraid I have no idea what '' lechuza soil with normal palms earth and expanded clay '' is. I would have chosen peat based multipurpose compost. The pot should have adequate drainage holes. The problem could possibly be over watering, leading to root rot.
There are many other insects that can cause similar problems. The sticky leaves could be a result of such insects (for example spider mites or scale) It would be no good complaining on eBay now as you have removed the plant from it`s original pot.

Dont worry I am experienced and the soil is completely good!
But I looked at the roots and there is no rott, There are no little insects like spider mites or scale... nothing :/
Do you have another ideas?

Your knowledge is obviously much greater than mine, and I am surprised you needed to ask for any help at all

Greetings, welcome to the Forums.

Some plant with variegated leaves are prone to such discoloration when conditions vary from optimal for even a little while. Generally, such variegation is not a maximally fit trait for most plants. Nevertheless humans artificially select for such unusual foliage because it is perceived as rare and beautiful. Part of the reason variegated aroids, such as Monstera deliciosa 'Albo-variegata' are so expensive is because many of them are both slow growing and tricky to grow well.

Irrigation, humidity, light, temperature and nutrition could all be factors that cause leaves to brown. Let's go over what the plant prefers.

Monstera deliciosa should be planted in rich and well-draining soil. The soil should be let to partly dry before irrigating. Judge water need by observing soil moisture and plant growth rate. Do not water blindly on a set schedule.

Normal house temperatures between 50º and 80º degrees are best, though established plants outdoors can take both hot temperatures and brief episodes of cold weather and very light frost, though growth will stop and there may be some damage.

Light and humidity should be considered in relation to temperature. As temperature increase, light should decrease and humidity should increase. Finding the right balance for your site conditions may require some trial and error.
A variegated plans should ideally receive more shade than a non-variegated form, especially when temperatures are high and humidity is low, which is the usual case indoors. This will slow the growth rate.

Fertilize lightly with a comple, general-purpose liquid fertilizer when the plant is in active growth.

I found the same thing this year. I switched fertilizer and I am certain the fertilizer is the culprit. Only thing I can do is drench and drain, cut the affected leaves, maybe replace soil, and hope for better next growing season

I have the same problem and people keep telling me it is thrips but I don’t see any other evidence of them?!

How long have you had it?
How long has it been in that pot?
How big is it in relation to the pot size?
Does the pot have drain holes?
How do you check the moisture of the soil?
How often do you check the moisture of the soil?
How close to a light source is it?
Is it a window or grow light?
Are there curtains or blinds on the window (if that is the source)?
Do you have a humidifier for it?
Have you fed it?
What did you use and how?
Have you seen any evidence of any insects at all?

As Marck has noted, variegated plants are more sensitive to environmental conditions than plain green ones.
