Monstera Lower Leaves Yellowing – House Plant Journal

Monstera Lower Leaves Yellowing

Plant: Monstera deliciosa

How long have you had the plant? 6 months to 1 year

Concerns:

I’ve noticed the older leaves becoming yellow, which I assume is part of the life and death process of an old leaf. However, when multiple old leaves started turning yellow, I noticed that a couple of aerial roots had started to rot. (I repotted the plant about 4 months ago due to roots growing).

To inspect further, I checked how the roots were doing, and they are none existent, all mushy and falling off. However, my new leaves are green, healthy and not dropping. But I have noticed it is slow at putting out new growth (even for this season).

I’m worried my plant is dying.

Light Situation:

How do you determine WHEN to water? I wait for the soil to become completely dry.

Describe HOW you water: I fully soak the soil, letting excess drain away.

What fertilizer (if any) do you use? I recently started using fertilizer – Fiddle leaf fig plant food (recommend on your website)

Soil situation:

Darryl’s Analysis

Environment:
That’s an excellent spot for your Monstera in terms of light!

Effort:
In terms of the WHEN to water, you don’t have to wait for the soil to become completely dry – just beyond halfway dry is when I’d water a monstera.  In terms of the HOW to water – soaking and letting excess drain away is great.

The reason you are seeing multiple yellowing leaves is because you have multiple vines in the pot – I think I see 4 separate vines.  This isn’t a major problem but with such great light, your plants are likely growing quickly and crowded in this pot.  My single Monstera vine has outgrown its 6″ pot in a matter of a year so I can only imagine that your 4 vines are quite crowded and competing for resources.  You can go up in pot size to roughly the same size as your largest leaf – but for multiple vines, I’d go up one size more from that (so if I’m just eyeballing your situation – maybe go up to a 12-14″ pot).

Expectations:
Your plant is doing fine from what I can see.  The lower leave are always the first to die off.  Just cut them off once they are fully yellowed – you can probably just gently pull them off when they’re ready.  It is not a signal that there’s anything wrong because your light is excellent and you are watering/fertilizing accordingly.

Leaves have a limited lifespan, which is why you shouldn’t judge plant health SOLELY on leaves dying.  The more sensible thing to do would be to understand what are the best possible growing conditions and care efforts you can realistically do, and, beyond that, accept what Nature has in store.

Learn this approach to plant care and you’ll be less worried and more satisfied with plants – learn from my course.
