You have 6 groups of plants that it is advisable to consider for your fishpond. This short article and a couple of of the following ones are all concerning what we name Marginals. When we discuss Marginal plants we think of these as merely ornamental since they do not play a part in managing a satisfactory balance in the pond. They only serve 2 functions. The boundary linking the water and also the water garden side is softened by using these plants which is often desirable in a Formal fishpond and is at all times essential in an Informal one, they supply floral colour and/or interesting leaves through the growing season. Many types are obtainable. Based on the variety of plant, the recommended depth for planting is 0-6 inches.
The home is generally on the marginal shelf or in the shallows of your pond. The normal approach to growing them is usually to plant them in soil at the bottom of the shelf, but it is better to put them in baskets. You should not mix different varieties in a single container. Below are a couple of plants that We have placed into my pond to add a bit of colour.
Carex (Sedge). The Sedges are incorporated here as they’re generally found within the Marginal plant section of your numerous catalogues, although, these grassy perennials are normally happier developing in wet soil instead of within the pond. Planting depth when grown as a Marginal is 0 – 2 inches. There’s nothing special about these plants, however the yellow-leaved Carex stricta ‘Bowles Golden’ is becoming somewhat fashionable in recent times. The tall Sedges can look attractive at the water’s edge of a large pond, but they have no place in the average sized one. For the ordinary garden pond there are more interesting Marginals than Carex.
Cyperus (Umbrella Grass). These graceful members of the Sedge family are foliage plants which bear lance-shaped leaves which spread out from the tops of the stems like the ribs of an umbrella. The summer flower heads are branching spikes of small brown or reddish flowers. The favored one would be the sweet Garlingale (Cyperus longus) which is utilised to consolidate the banks of natural pond sand and is cut for flower arranging. An invasive plant growing to about 3ft high. Planting depth is 3 – 5 inches. The dark green leaves are coarse and spiky. C.vegetus is more compact and thus more suitable for the regular garden fishpond. The leaves are broader than those of C. longus but the stems are only 1- 2ft high. The advisable planting depth is 0 – 4 inches. and it can be grown in a bog garden.
Cotula (Golden Buttons). A handy Marginal, in particular for the small ponds. The spreading leafy clumps are no greater than 6 inches in height and are covered all summer long with little yellow button-like flowers. The foliage is scented. Cotula coronopifolia is an annual and meaning that it dies when the flowering season is concluded. This lapnt normally doesn’t pose a problem as the plant readily sets seed and a flush of self-sown seedlings in spring replaces last year’s specimens. The recommended planting depth for Cotula is 0-5 inches.
