Best Pot for Sacred Lotus
What Size Pot Does a Sacred Lotus Need?
Lotus grows from thick, spreading rhizomes that creep horizontally, so width matters more than depth. A container that is at least 18 inches across and 10 inches deep gives the rhizomes room to run and lets you maintain a few inches of water above the soil surface.
When your lotus fills its container and new growth starts climbing over the rim, it is time to move up. Choose a pot 4 to 6 inches wider to give the rhizomes another season or two of room.
A container that is too small causes the rhizomes to circle and crowd, which weakens flowering. One that is far too large can delay blooming because the plant puts all its energy into spreading before it flowers.
What Material Pot Is Best for Sacred Lotus?
Lotus roots sit in dense, waterlogged clay soil beneath several inches of standing water. The container must hold water without draining, so anything porous is a poor fit. You need a material that is watertight, sturdy enough to hold heavy wet soil, and won't degrade from constant moisture.
Weight is also worth thinking about. A large lotus container full of wet soil and water can weigh over 100 pounds, so choose a material you can move if needed or place it in its permanent spot before filling.
Sacred Lotus is an aquatic plant that grows in standing water, so the pot needs to hold water in, not drain it out. That rules out anything porous. Fabric drains freely and unglazed ceramic wicks moisture through its walls, so neither will work.
Plastic tubs are the most popular choice among lotus growers because they are cheap, watertight, and come in large sizes. Glazed ceramic bowls without drainage holes are another beautiful option. Sealed wooden tubs and metal containers both work, though metal can warm the water more than lotus prefers on hot days.
Does My Sacred Lotus Need Drainage Holes?
No. Sacred Lotus is one of the few plants that should not have drainage holes. The container needs to hold several inches of standing water above the soil at all times, which is impossible with a draining pot.
If your only container has holes, plug them with silicone caulk or a rubber stopper. Make sure the seal is watertight before adding soil and water.
When Should I Repot My Sacred Lotus?
Repot your lotus every one to two years in early spring, just as new shoots begin to emerge from the tuber. The rhizomes spread quickly and will fill a container in a single growing season.
To repot, gently lift the entire root mass and trim back old, mushy sections of rhizome. Keep firm, healthy tubers with visible growth tips. Replant in fresh heavy clay soil with the growing tips pointing toward the center of the new container.
After repotting, add water slowly over a few days. Start with just an inch or two above the soil, then raise the water level as new leaves appear.
Can I Plant My Sacred Lotus in the Ground?
Sacred Lotus is hardy in zones 4a through 10b, which covers most of the continental US. In-ground planting means putting the lotus in a natural or man-made pond where the rhizomes sit in soil at the bottom and leaves float or stand above the surface.
In zones 4a through 6, make sure the pond is deep enough that the rhizomes sit below the ice line in winter. If your pond is shallow, move the container to a frost-free garage or basement for the winter. In zones 7 and warmer, lotus can stay in outdoor ponds year-round with no protection.
