When and How to Water Philodendron ‘Mcdowell’

Like other drought-tolerant plants, the Philodendron McDowell can handle some neglect when it comes to watering. It is important to allow the soil to dry out between waterings to prevent root rot. Overwatering can be more harmful than underwatering for this plant.

A good rule of thumb is to water it when the top inch of the soil feels dry to the touch. You can water it thoroughly typically for 1-2 weeks, allowing excess water to drain out of the pot to prevent root rot. 

In the fall and winter, during the dormant season, the McDowell Philodendron plant doesn't need as much water. You should reduce the frequency of watering to once a week. It's essential to adjust your watering schedule based on the plant's needs and the environmental conditions. Overwatering can be more harmful than underwatering for this plant, so it's better to err on the side of slightly underwatering than overdoing it. Just keep an eye on the moisture and adjust accordingly to keep your Philodendron happy and healthy!

Light Requirements – Where to Place Your Philodendron Plant

Just avoid placing it in direct sunlight as that can scorch its leaves. If you notice the leaves turning yellow or brown, it might be getting too much light. 

For outdoor cultivation, Philodendron McDowell can still do well in bright, indirect light. It's best to place it in a spot where it gets filtered sunlight or dappled shade.
