Pond Plant Fertilizer for Healthy Aquatic Plants

When your pond and bog plants may benefit from feeding

Every two to four weeks from spring through late summer, while the water is warm and plants are growing
For potted water lilies, lotus and marginals fed at the roots
When new pads come in smaller or paler than the ones before
For floating plants like water hyacinth and rooted bog plants on one schedule
As the season warms and flowering plants begin setting buds

Pond plants follow water temperature closely, growing fastest in summer heat and going dormant in fall, so feeding is one part of care alongside sun and how each plant is potted.

Frequently asked questions

Can I use this in a pond with fish and frogs?

Pond Plant Fertilizer is formulated for rooted aquatic plants. The way you apply it matters: work the diluted feed into the soil of potted water lilies, lotus and marginals rather than pouring it into open water. That puts the nutrients at the roots, where your pond and bog plants take them up, and keeps them out of the water column where fish and frogs live.

How often should I feed pond plants?

Every two to four weeks from spring through late summer, while the water is warm and your pond and bog plants are actively growing. Pond plants follow water temperature closely: water lilies and lotus grow fastest in the heat of summer and use nutrients steadily then. Pond Plant Fertilizer is a liquid feed, so a regular application on that schedule keeps nutrition arriving as your plants push new pads and buds. Stop in fall as growth slows and your plants go dormant for winter.

How do I dose it?

Two ways, depending on how your plants are grown. For potted pond plants, mix Pond Plant Fertilizer at the recommended dilution and push the diluted feed into the soil around the roots, so your plant takes it up directly and little reaches the open water. For a tank or pond where dosing the water itself is the practical option, dose at the recommended dilution for your total water volume, so knowing roughly how many gallons you have is the starting point.

Which plants can I use it on?

Pond Plant Fertilizer is formulated for rooted aquatic and bog plants: water lilies and lotus in their pots, marginals such as pickerel rush, cattails, water iris, cardinal flower and marsh marigold, and floating plants like water hyacinth. These plants share the same basic needs, nitrogen for pads and leaves and phosphorus and potassium for roots and blooms, so one formula on one schedule covers a mixed pond. Feed each potted plant at its roots for the most direct uptake.

When will I see results?

New growth shows it first: water lilies, lotus and marginals fed with Pond Plant Fertilizer send up new leaves that are greener and larger than the ones before, since the nutrients reach the roots directly in the soil. Flowering plants respond as the season warms, setting buds. Existing yellowed pads won’t re-green, so you’re feeding the growth that follows; results are slower in cool water.
