Planting spider plants: rooted babies, pots and the first watering

Planting spider plants starts with choosing which job you are doing: potting a rooted baby, encouraging a still-attached plantlet to root, or moving an established plant into a larger pot. They look similar at the end, but the starting material needs different handling. For a first attempt, a healthy baby with visible roots is the clearest option.

Set up the pot before separating a baby

Use a pot with drainage holes and a houseplant or peat-free multipurpose potting mix. A decorative outer pot is useful for protecting furniture, but it must not trap the plant in standing water. Keep the inner pot removable so you can water and drain it away from a shelf.

Choose a container proportionate to the roots rather than the full spread of the leaves. A long, arching leaf is not a reason to put a tiny root system into a large volume of wet compost. Put everything on a washable tray, have a clean pair of scissors ready and choose the final position before starting.

Plant a baby that already has roots

• Inspect the parent and plantlet for obvious pests or damaged growth. Start with healthy material.

• Detach a good-sized plantlet that has developed roots. Hold the leafy base gently rather than pulling on individual leaves.

• Make a shallow planting space in moist potting mix, place the roots in it and bring the mix around them. Keep the centre of the leafy rosette above the surface.

• Water gently, let excess water run out and empty the saucer or outer pot.

• Place in bright, indirect light while it settles. Protect from hot direct sun and nearby heaters.

The Royal Horticultural Society also describes rooting detached plantlets in water before potting them individually once their roots lengthen. That is an alternative starting method; it is not a reason to keep the eventual compost pot permanently flooded.

Leave an unrooted plantlet attached while it roots

Wisconsin Extension describes a useful alternative: set a still-attached plantlet on the surface of a separate pot of soilless growing medium, hold it in contact and let roots develop before severing the connecting stem. Position the two pots securely so a falling pot cannot pull on the parent. This is particularly convenient when both can stand together on a tray.

Do not tug repeatedly to check whether roots have formed. Look for establishment and handle the connection cautiously when you eventually separate it. If the location cannot hold two stable pots, start with a plantlet that is already rooted rather than balancing containers on an edge.

Repot an established plant when the roots need room

Check the root ball instead of repotting by the calendar alone. When fleshy roots fill the container and growth slows, choose a slightly larger pot and fresh mix. The RHS suggests repotting commonly becomes necessary every year or two after the first year, while the actual pace depends on growth and container size.

After planting, check the mix with a finger and adjust watering to conditions. Aim for lightly moist compost with drainage, allowing some drying between thorough waterings. A bright warm room and a cooler room will not need identical schedules. Brown tips can have several causes, so do not respond automatically with extra fertiliser or a larger pot.

A position that works in the room

Leave space for leaves and trailing stems without blocking a walkway or pulling the plant against a radiator. A hanging container needs a support suitable for its filled weight; if you cannot establish that safely, choose a stable shelf or plant stand. Start with one well-placed pot and observe it before expanding the display.
