Your marginal plant will arrive in a Finofil Aquatic Basket, pre-planted with aquatic soil and a slow-release fertiliser. Just pop straight into you pond upon arrival!

Aquatic Basket Measurements:

• 1ltr - Square pot (11cm wide by 11cm high)
• 3ltr - Hexagonal pot (18cm wide x 16cm high)
• 5ltr - Square pot (24cm wide x 14cm high)
  
• 9cm plants arrive in solid pots and will need repotting into aquatic baskets.

Growing Instructions: Place the plant on a marginal shelf at the recommended depth. Allow 5 x 1ltr plants per linear metre or 3 x 3ltr plants per linear metre.

Growing Tips: To maintain vigour and prevent overcrowding, divide clumps every few years in early spring.

Pruning: Remove spent flower heads and dead foliage after flowering to maintain a tidy appearance and encourage fresh growth.

Pests/Diseases: Rarely affected by pests or diseases; monitor for powdery mildew in dry conditions.

How Deep Should I Place My Marginals?

The planting depth depends on the variety. Check the product page or the care label included with your plant for specific guidance.

Depth is measured from the top of the pot to the water’s surface.

Most marginals are fine placed 1cm to 2cm under the waterline, just enough to hide the aquatic basket.

How Many Marginals Do I Need?

Measure the length of your marginal shelves and then allow:

• 1ltr Plants: 5 per linear metre
• 3ltr Plants: 3 per linear metre

Tip: Leave space between plant varieties to prevent dominant species from taking over. For more details, see our Planting Guide.

Do I Need to Line My Basket with Hessian?

No, Finofil aquatic baskets are designed with a fine mesh that prevents soil loss. Adding a liner is optional but not necessary.

What Are Finofil Baskets Made From?

Finofil aquatic baskets are made from 100% recycled plastic and manufactured in the UK. They can be recycled at local recycling centres or through kerbside collections that accept black plastic. Plant labels are also recyclable.

Will Carp or Ducks Eat My Plants?

Carp (inc. Koi): These fish find pond plants irresistible! If you have carp, we recommend protecting your plants with barriers.

Goldfish: Goldfish may nibble on oxygenators and softer plants but generally cause less damage. They also eat insects, larvae, and tadpoles.

Wildfowl: Ducks and other birds may eat plants or damage roots while nesting. Mature plants with strong root systems are more resilient, but consider protecting roots/rhizomes for added security.

What is a Pre-Order?
Pre-ordering reserves a plant that is still growing and not yet ready to ship. Payment is taken at checkout to secure your plant, and shipping happens once the plant is well-rooted and ready.

Benefits of Pre-Ordering:

• Secure popular plants before they sell out.
• Receive healthy, pond-ready plants straight from the grower.

Plant Availability:
Plants are released in phases:

• Phase 3 (June): Ships by late June (e.g., Pickerel Weed).
