A practical Guide to Pond Plants and Aquatic Baskets

A Practical Guide to Pond Plants and Aquatic Baskets

Pond plants come in various shapes and sizes, but also have very different growing habits, so it is not surprising that things can get quite confusing when trying to choose the right sized aquatic baskets to house the right pond plants. This article has been written as a guide to make the whole process much easier.

Always line aquatic baskets with Hessian Liners or cloth liners.

17 cm round, 23 cm round and 24 cm square and oxygenating baskets =45 cm hessian or cloth liners

29 cm square, and contour baskets=60 cm hessian or cloth liners

40 cm large square aquatic baskets=90 cm hessian or cloth liners.

Water Lilies and Nuphars

Water Lilies come in various sizes, for example Pygmaea Helvola is a miniature cultivar with tiny leaves the size of a ten pence and rhizomes the size of an Acorn, at the other end of the scale are numerous large growing cultivars with leaves that can grow to 18 inches in diameter and rhizomes as wide as your forearm.

Planting Recommendations

Small and miniature cultivars (leaf spread 30-60 cm) =17 cm round aquatic baskets.

Medium sized Cultivars (leaf spread 60-90 cm) = 23 cm round or 24 cm square aquatic baskets.

Large cultivars (leaf spread 90-150 cm) = 29 cm square or 40 cm square aquatic baskets.

Planting Tips

Plant upright growing rhizome types in the middle of the basket, grow angle shaped rhizomes types and long narrow horizontal rhizome types the cut part of the rhizome up against the side of the basket to allow plenty of room for growth

NEVER plant Water Lilies into cloth planting bags as new growth will push against the sided creating material folds that will trap and confine growing tips and prevent your water Lily from flowering.

Creeping Marginal Plants and Oxygenating Plants

A lot of marginal pond plants have a creeping growing habit and very shallow root systems, they include plants such as Veronica Becabunga, Phyla Lanceolata and Lysimachia Nummularia, Creeping plants and oxygenating plants grow best when planted into 20 cm square shallow oxygenating baskets.

Water Iris

There are several different types of Water Iris, and they all have different growing habits

Planting Recommendations

Iris Laevigata and Iris Versicolor species and cultivars

These types are less invasive and clump forming in habit so best planted into 23 cm round or 24 cm square aquatic baskets

Iris Pseudacorus species and cultivars

Iris Pseudacorus are fast growing and therefore require planting as single plants into 29 cm square aquatic baskets or 3 plants to a 40 cm square aquatic basket

Iris Virginica and Iris Louisiana species and cultivars

These types have rhizomes that grow sideways at quite a fast rate, and are best planted into contour baskets with the cut end of the rhizome up against the side of the basket at one end, allowing plenty of room for new growth.

Planting Tips

Plant upright growing rhizome types in the middle of the basket, grow angle shaped rhizomes types and long narrow horizontal rhizome types the cut part of the rhizome up against the side of the basket to allow plenty of room for growth

NEVER plant Water Iris into cloth planting bags as new growth will push against the sided creating material folds that will trap and confine growing tips and prevent your Iris from flowering.

For best results Re-pot Iris Pseudacorus, Iris Virginica and Iris Louisiana every 2 or 3 years.

Shallow and Deep Marginal Plants and submerged Pond Plants

Marginal plants come in all shapes and sizes, I have already covered Creeping Marginal Plants and Water Iris above, the rest can be planted into a range of different sizes aquatic baskets, smaller growing Marginal Plants such as Ranunculus Flammula will grow happy in 17 cm round baskets, while the very tall magnificent Thalia Dealbata won’t want anything smaller than a 29 cm square basket

Planting Tips

NEVER plant Rhizome type Marginal plants such as Pontaderia and Typha into cloth planting bags as new growth will push against the sided creating material folds that will trap and confine growing tips and prevent your Iris from flowering.

Always grow tall rushes etc into 29 cm square or 40 cm square aquatic baskets so they are stable in the wind and don’t blow over.
