Hosta 'Guacamole' (Guacamole plantain lily) care

Light

Hosta 'Guacamole' wants the spot a few feet back from a sunny window — bright enough to read a paperback at noon, but the sun never falls directly on the leaves. Performs best in dappled or partial shade. Morning sun with afternoon shade is ideal; deep shade reduces the chartreuse leaf colour, while hot afternoon sun scorches the foliage. A faint hand shadow at midday is the right amount; a sharp dark shadow means it's getting direct sun and probably too much.

Watering

Water hosta 'guacamole' when the top 2-3 cm of soil is dry, roughly every 5-7 days in summer. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Keep soil consistently moist but not waterlogged. Water at the base to avoid wetting the foliage and reduce risk of fungal disease. Reduce watering in autumn as the plant goes dormant.

Soil and pot

Hosta 'Guacamole' grows best in moist, humus-rich, well-draining loam. Amend heavy clay or sandy soils with plenty of garden compost or leaf mould before planting. A slightly acidic to neutral pH of 6.0-7.0 is optimal. Good drainage prevents crown rot. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Hosta 'Guacamole' sits happiest at around 50-70% humidity and 5-25°C (41-77°F). Appreciates moderately humid conditions typical of a shaded garden border. In dry climates, a layer of mulch around the base helps retain soil moisture and maintain humidity around the crown. If you keep the room above 5 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed hosta 'guacamole' sparingly. Apply a balanced slow-release granular fertiliser (e.g. 10-10-10) in early spring as the pips emerge. A liquid feed at half strength once a month through summer maintains vigour without promoting excessive, slug-prone lush growth. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on hosta 'guacamole' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Slug and snail damage — Hostas are highly attractive to slugs, which shred the foliage overnight. Use iron phosphate pellets, copper tape, or encourage natural predators; avoid bare soil around crowns.
• Vine weevil — Larvae feed on roots, causing sudden collapse. Apply nematodes (Steinernema kraussei) to moist soil in late summer or autumn.
• Leaf scorch — Brown, papery leaf edges result from too much direct afternoon sun or drought stress. Move to a shadier position and mulch well.
• Hosta virus X — Mosaic-like blotching and distortion with no cure. Destroy affected plants promptly and sterilise tools to prevent spread.
• Crown rot — Caused by waterlogged soil or excessive moisture around the crown. Ensure good drainage and avoid overhead watering.

Companion plants

Hosta 'Guacamole' pairs well with Astilbe, Ferns, Heuchera, and Ligularia. These are species with similar light and water needs, so you can group them in the same room or on the same shelf and water as a batch.

Propagation

Divide established clumps in early spring or early autumn, ensuring each division has several healthy growth buds. Replant divisions at the same depth in refreshed, compost-enriched soil. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Hosta 'Guacamole' is toxic to pets. The ASPCA lists Hosta spp. as toxic to dogs, cats, and horses. Ingestion of any part causes vomiting, diarrhoea, and depression due to saponin glycosides. Keep pets away from all parts of the plant. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
