When Can My Pond Be Planted With Water Lilies?

Growing water lilies is a simple process that requires only a few essentials: a water lily pot, aquatic planting soil, and a container. Choose a pot that is five-gallon for one water lily or nine-gallon for two water lilies, and use 10-pounds for one water lily or 20-pounds for two. Select a wide and shallow container that is 18 inches wide by at least.

Water lilies require still water and full sun, with each type requiring a specific planting depth. Place the waterlily on a 20cm-deep container in a pond or aquatic planter to control their growth, ensure they get plenty of sun, trim old flowers and leaves to prevent rot, and divide them.

Water lilies are valuable to ponds as they not only look great and flower well but also provide shade by providing shade. They can be planted from April to September, with the most appropriate size typically being large waterlilies sitting 75cm below the surface, medium waterlilies 50cm below, and small waterlilies 20cm below.

When planting water lilies, remove the plant from the pond in late spring or early summer, cut it into several smaller sections, and plant the small sections into the pond. If growing hardy varieties, leave them in the pond as long as the water doesn’t freeze. Plant the waterlily in an aquatic planter approximately 14″ x 7″ in size using a proper aquatic potting media.

Water lilies are best planted from mid to late spring to mid-summer, and are best grown in aquatic planting baskets. Water lilies should be placed in still pond water away from constant splashing and flow currents from filter outlets, fountains, and waterfalls.

Can lilies be dug up and replanted?

In early fall, dig and divide Asiatic, Oriental, and other garden lilies (Lilium spp) by carefully separating the bulbs and planting them immediately. If planting is delayed, place the bulbs in a plastic bag with lightly moistened peat moss and refrigerate. Plant large bulbs 4 to 6 inches deep, while small bulbs should be 1 to 2 inches deep. Lilies thrive in well-drained soil in full sun, with large bulbs blooming the following summer.

Can you have too many water lilies in a pond?

Water lilies in a pond can be overcrowded and overgrown, potentially causing oxygenation issues and suffocating fish and other plants. They help control algae by absorbing light from the water, but if they cover too much, they can prevent oxygenation and cause the plants to decay below the water. Thinning plants is recommended when buds in the water cannot rise to the surface and end up decaying below it. A rule of thumb for fish is to cover no more than 70% of the water surface.

Do water lilies multiply?

Water lilies are aquatic plants that spread by producing tuber-like rhizomes, which are underground stems that store water and nutrients. These rhizomes bear leafy shoots that can be split apart to create new plants. To propagate, lift the basket of water lilies before the flowering season and gently pull the plant out of its container. Cut through the roots with a large bread knife, aiming to get as many cuttings as possible from each rootball. Line the bottom and sides of the new basket or pot with hessian to prevent compost from draining away.

Place the new plant in the middle of the pot, filling it with the remaining soil, leaving the emerging green shoots at ground level. Avoid using garden soil for repotting aquatic plants, as it encourages green algae growth. Fold the remaining hessian over the soil and add grit to prevent the plant from floating away. Place the plant into shallow water, ideally in a sunny, open position.

Can you plant lilies anytime?

Lilies can be planted from late autumn to early April, either as bulbs or potted plants. Potted lilies require at least 12cm of soil above the bulb, while larger, firm bulbs can be found at garden centers. Planting lily bulbs 15cm apart and three times the depth of the bulb’s height is recommended. To care for lilies, support tall-growing plants with a plant support, feed them with tomato feed every fortnight, deadhead spent blooms to prevent energy waste, except for martagon lilies that self-seed. Never cut flowering stems back to soil level, but leave them in place until they brown, as they provide energy for the bulb.

Do water lilies add oxygenate a pond?

Water lilies are essential for wildlife, providing food, protective cover, cooling water temperatures, and absorbing water-polluting nutrients. They help cool water temperatures and absorb water-polluting nutrients through nitrogen fixation, a process that breaks down organic debris in ponds. Excessive inputs of phosphorus and nitrogen can trigger eutrophication, promoting algal bloom and deteriorating water quality and aquatic biodiversity. Water lilies, primarily used as ornamental plants, have been found to mitigate polluted aquatic environments by increasing dissolved oxygen concentration in the aquatic environment.

To fertilize water lilies without harming wet pets like koi and goldfish, slow-release tablets have been developed. PondMax – AquaBloom Aquatic Plant Food is recommended for water lily fertilization, providing nutrients for plant health and flower formation. Nymphaeaceae varieties, such as Hardy and Tropical, reproduce via seeds, tubers, and viviparously. Aquascapes Pond Plant Potting Media is recommended for starting seeds, tubers, or transplants, as it is free of peat, compost, fertilizers, and pesticides that could cloud water and harm animals. Floating planters are also available to stabilize the lily tuber and roots within the basking, allowing the pad and flower portions of the plant to move around the pond.

How many water lilies per pond?

Water lilies can be planted in various sizes, depending on the size of the pond and the plant’s maturity. Large lilies, like Attrraction, require one lily for every 2m² of water surface area, while medium lilies, like James Brydon, require one lily for every 1. 5m² of water surface area. Small lilies, like Froebelii, require one lily for every 1m² of water surface area, and miniature lilies, like Pygmy Helvola, require only 1/2m² of water surface area.

To display lilies, clear water should be shown all around the plant. When choosing the variety and number of water lilies, consider factors such as the overall size of the pond, the mature size and vigor of the plant, the depth of the pond, grouping two or three lilies of the same variety, and any factors that may restrict plant growth, such as shade, pumps, fountains, cascades, or waterfalls.

How quickly do water lilies spread?

The water lily propagates vegetatively via its rhizome and seeds, resulting in the formation of a surface cover of 15 feet within a five-year period. The rapid spread of water lilies through ponds presents a challenge to their management. The water lilies can flourish in waters of a depth of 6-7 feet, with the optimal depth varying based on the water clarity.

What month is best to plant water lily?

Waterlilies are best planted from mid to late spring to mid-summer in aquatic planting baskets. They should be cut back, removed, and filled with unfertile loamy soil or aquatic planting compost. The plant’s crown should be at soil level, and the compost surface should be covered with washed pea shingle. Water the compost well and allow excess water to drain before placing it in the pond. Submerge the plant slowly in the water, ensuring 10-25cm (4-10in) of water covers the crown and leaves float on the surface. The final planting depth should be given on the plant’s label, and the basket can be placed on a raised platform to ensure the correct depth.

What month is best to plant lilies?

Lilies are a slow-growing plant that can be planted in fall or early spring, with planting at least four weeks before the last frost date to ensure strong roots before ground freezes. They grow as single or multiple unbranched stems, with flowers held in clusters at the top or borne along the stem. Lilies come in various flower colors and can be trumpet-shaped, recurved, or open. They are grown for their flowers, making them ideal for growing in between other fuller perennials and shrubs.

Staking is necessary for Oriental hybrids with large heavy blooms and 3-8 foot tall stems, while Asiatic hybrids form self-supporting clumps over time. Growing lilies through other shrubs provides a natural framework for the plant while hiding its legs.

Do water lilies have deep roots?

Lily pads are popular for their dimension, beauty, and variety. They grow from tubers and prefer to be 24-inches deep in fresh water. Different types of water lilies thrive in different planting zones, such as Zone 5, which is where most of Colorado is located. Hardy water lilies thrive in this zone, which can withstand temperatures between -10°F and -20°F. Tropical lilies, which bloom at night, are fun but cannot withstand the cold, so they are not recommended for purchase in Colorado.
