How to Grow Alstroemeria ‘Indian Summer’

Alstroemeria ‘Indian Summer’ is a beautiful perennial plant that produces vibrant orange flowers. Here are some general guidelines to help you grow and care for Alstroemeria ‘Indian Summer’:

  1. Planting location: Choose a planting location that receives full sun to partial shade. Alstroemerias prefer well-draining soil with a slightly acidic to neutral pH.
  2. Soil preparation: Prepare the soil by adding organic matter like compost or well-rotted manure. This will improve the soil’s fertility, drainage, and water-holding capacity.
  3. Planting time: Plant Alstroemeria ‘Indian Summer’ in the spring or fall when the soil has warmed up or cooled down. This will allow the plant to establish itself before the extreme temperatures of summer or winter.
  4. Planting process: Dig a hole that is deep enough to accommodate the plant’s root ball. Place the plant in the hole, ensuring that the crown (where the stems meet the roots) is level with the soil surface. Backfill the hole with soil, gently firming it around the roots.
  5. Watering: Alstroemerias prefer consistently moist soil but not waterlogged conditions. Water the plants deeply once or twice a week, especially during dry periods. Avoid overhead watering, as it can lead to fungal diseases. Instead, direct the water to the base of the plant.
  6. Mulching: Apply a layer of organic mulch around the base of the plant to help retain moisture, suppress weed growth, and maintain a more even soil temperature.
  7. Fertilization: Feed Alstroemeria ‘Indian Summer’ with a balanced slow-release fertilizer in the spring when new growth begins. Follow the package instructions for application rates. Avoid over-fertilization, as it can lead to excessive foliage growth at the expense of flowers.
  8. Support: Alstroemerias can benefit from some support to keep the stems upright, especially when they become top-heavy with flowers. Install stakes or use a trellis system to provide support and prevent the stems from bending or breaking.
  9. Deadheading: Remove spent flowers regularly by cutting the stem back to the base or to a healthy leaf node. This will encourage the production of more blooms and maintain a tidy appearance.
  10. Winter care: In colder regions, apply a layer of mulch around the base of the plant to protect it during winter. Cut back the foliage to a few inches above the ground after it has died back naturally in the fall. This will help the plant conserve energy and promote new growth in the following spring.
