Philodendron hederaceum ‘Lime’  Care Guide:
Placement: Thrives in warm, bright spaces with indirect sunlight. Ideal for shelves, hanging baskets, or climbing structures.
Light: Philodendron hederaceum ‘Lime’ prefers bright, indirect light, though it adapts to lower light conditions. Avoid prolonged direct sun exposure to prevent leaf scorching.
Watering: Let the top layer of soil dry out between waterings. Overwatering can lead to root rot, so ensure the pot has drainage holes.
Humidity: Adapts well to typical indoor humidity but benefits from slightly higher levels. Misting is not recommended; instead, use a humidifier if needed.
Temperature: Ideal range is 18-27°C; avoid exposure to cold drafts or sudden temperature drops.
Soil: Philodendron hederaceum ‘Lime’ requires well-draining, airy potting mix with organic matter for optimal root health. A mix of peat, perlite, and bark works well.
Repotting & Pot Choice: Repot every 1-2 years or when roots outgrow the pot, using a slightly larger container with drainage holes.
Fertilization: Feed monthly with a balanced liquid fertilizer to support continuous growth. Avoid excessive feeding to prevent nutrient buildup.
Propagation: Philodendron hederaceum ‘Lime’ is easily propagated through stem cuttings placed in water or directly into soil. Roots develop quickly in water before transitioning to soil.
Semi- and Hydroponics: Thrives in semi-hydroponic setups like LECA or passive hydroponics. Also adapts well to full hydroponic growing in nutrient-rich solutions.
Pruning: Regular trimming encourages bushier growth and prevents legginess. Remove any yellowing or damaged leaves to maintain plant health.

Etymology
The genus name Philodendron originates from the Greek words ‘philo’ (love) and ‘dendron’ (tree), referencing its natural inclination to climb and embrace tree trunks. The name hederaceum refers to its ivy-like growth habit. Philodendron hederaceum was originally described by Jacquin in 1829 and later reclassified by Schott. Its synonym scandens comes from the Latin scandere, meaning "to climb."  The specific variety ‘Lime’ is named for its bright, citrus-hued foliage, distinguishing it from its darker-leaved relatives.
