FAQs

When is the best time to plant these plugs?

Plant them out once the risk of spring frost has completely passed in your region.

Are these plants hardy?

Yes, they are hardy perennials, but in very cold climates, a layer of mulch over the base in winter can provide extra protection.

How wide does the plant spread?

Each plant can reach a mature spread of approximately 75cm.

Can I grow these in pots?

Absolutely, they thrive in large patio containers provided there is excellent drainage.

Do I need to deadhead the flowers?

While not strictly required, removing spent stems helps redirect energy into new flower production.

Are they toxic to pets?

Alstroemeria can cause mild irritation if ingested by cats or dogs; it is best to keep them in an area not accessible to curious pets.

Troubleshooting

Plant growth is stunted or pale

Check soil drainage; ensure the plant is receiving at least 6-8 hours of direct sunlight daily.

Lack of flowers

Ensure the plant is receiving enough potassium-rich fertilizer and that it is not being shaded by taller shrubs.

Stems falling over

Provide support with garden stakes or a decorative ring, especially in exposed, windy locations.

Pros and Cons

  • Flowers are long-lasting in both the garden and vases

Setup, Compatibility & Care

Upon arrival, pot on your jumbo plugs into individual containers using high-quality potting compost. Keep them in a frost-free area until the plants are well-established and all risk of frost has passed. When transplanting to their final outdoor position, ensure the soil is well-drained, as Alstroemeria dislike sitting in heavy, waterlogged ground. Incorporate grit or perlite into the planting hole if your soil is heavy clay. Water regularly during the first growing season, especially during dry spells, and feed with a balanced liquid fertilizer every two weeks through the summer to support continuous flowering.
