How To Get Rid Of Spider Plants In Garden? | Tidy Up Beds

Guide / By

You can clear unwanted spider plants from garden beds by digging clumps, lifting runners, adding mulch, and using soil solarization where needed.

Spider plants look gentle in a pot, but once they reach open soil they knit into thick mats of leaves and baby plants. In mild climates they act like evergreen groundcover, filling shady corners, slipping between shrubs, and pushing out more delicate ornamentals.

This guide shows how to get rid of spider plants in garden beds with hands-on digging, smothering, smart use of solarization, and follow-up checks that keep the space clear.

Spider Plants In Garden Beds: Why They Spread So Fast

Spider plants (Chlorophytum comosum) are tough perennials with arching leaves and long stems that carry ready-made baby plants. Those plantlets already hold small roots, so once they touch damp soil they settle in fast and form new clumps, especially in shaded corners where they tolerate low light.

In frost-free or near frost-free areas, spider plants can live outdoors year round and often act as informal groundcover in light shade, weaving between shrubs and edging stones. Extension resources such as UF/IFAS Gardening Solutions and spider plant groundcover outdoors guides describe how outdoor plantings can spread when they escape containers.

Once a few clumps reach a good size, the plantlets arch outward and stitch the gaps between plants. That web of stolons and rooted offsets means you are dealing with a network of many small crowns instead of one central plant.

How To Get Rid Of Spider Plants In Garden Without Chemicals

For most home gardens, the most reliable answer is steady physical removal. It takes effort on the front end, yet it gives you full control over where you disturb soil and which nearby plants stay in place.

Step 1: Map The Infested Area

Before you pick up a tool, step back and note where spider plants have spread. Mark the outer edge of the patch, the heaviest clumps, and any isolated plantlets that have popped up a short distance away. Also note which shrubs or perennials you want to save and where deep digging would disturb roots or irrigation.

Step 2: Water And Loosen The Soil

A day or two before digging, water the bed deeply. Damp soil lets you pry out roots and stolons with less breakage. On removal day, use a hand fork or digging fork to loosen the soil around the first clump, placing the tines a short distance outside the leaves and rocking the tool back and forth so the whole root mass starts to lift.

Step 3: Lift Clumps And Runners

Once the soil moves, slide your hand under the base of the clump and pull upward while you lever gently with the fork. Shake excess soil back into the bed so you can see the root crown and attached stolons clearly. Follow each runner outward, pulling attached plantlets as you go and dropping every piece into a bucket or tarp.

Step 4: Comb For Missed Pieces

After the main plants are out, kneel and work through the area with your hands or a narrow weeding tool. Feel for remaining white roots, crowns, and small plantlets, and tug out anything that resembles the original plant, including single leaves with attached roots.

Spider Plant Removal Methods At A Glance

Different beds call for different tactics. The table below compares main ways gardeners remove spider plants from garden soil so you can mix and match methods for your plot.

Removal Method Best Used Where Core Steps
Hand Digging Clumps Small to medium patches among valued plants Water, loosen soil, lift clumps with a fork, remove roots and plantlets.
Lifting Mats With A Spade Dense carpets in open ground Slice under roots in strips, roll up mats, shake off soil, dispose safely.
Hand Pulling Plantlets New spread around edges of an older patch Follow each runner, tug out baby plants before roots thicken.
Sheet Mulch With Cardboard Beds you can leave covered for several months Cut plants low, lay cardboard and mulch, leave in place through a growing season.
Soil Solarization Sunny sites in warm climates Moisten soil, cover with clear plastic, seal edges, leave on for several hot weeks.
Spot Hoeing Isolated tufts in vegetable rows or paths Slice below crowns on dry days and repeat when new growth appears.
Potting Select Plants When you want to keep a few specimens Lift young clumps, pot into fresh mix, and grow them as contained houseplants.

Smothering Spider Plants With Mulch Or Cardboard

If spider plants have threaded around shrub roots or corners where digging is awkward, smothering often works better than constant hand pulling. The idea is simple: block light and new growth, starve the roots, and keep at it long enough that stored energy runs out.

Start by cutting the foliage close to the soil surface. Lay overlapping sheets of plain cardboard across the patch and cover them with a thick layer of coarse mulch. Tuck the material tight against trunks and edging stones so runners cannot sneak through gaps, and leave the covering in place for at least one full growing season.

Using Soil Solarization Against Stubborn Patches

In hot, sunny seasons, you can turn the sun into a tool against stubborn spider plant patches. Soil solarization means covering moist soil with clear plastic for several weeks so trapped heat damages roots, weed seeds, and other pests in the top layer of soil.

Extension resources such as the soil solarization guide from UF/IFAS describe how clear polyethylene sheeting warms the top 6 to 12 inches of soil enough to kill many weed species when it stays in place for four to eight weeks in peak summer. For spider plants that have formed a tight mat, remove as much top growth as you can, smooth the soil, water well, then stretch clear plastic over the area, bury the edges in a shallow trench, and leave the cover in place through the hottest part of the season.

Disposing Of Removed Spider Plants Safely

Piled spider plant crowns and plantlets stay alive far longer than many gardeners expect. Do not throw them onto an open compost heap or into a wild corner. Bag them for municipal green waste, dry them in full sun on a hard surface until the crowns are crisp, or send them out with household trash if garden waste collection is not available.

Some regional plant assessments now warn against casual dumping of unwanted ornamental plants, since many garden escapes began at the edge of a yard or parking lot. Treat your spider plant debris as you would any other persistent weed and remove it fully from the site.

When Herbicides Enter The Picture

Most gardeners can remove spider plants through physical methods alone. In a few tight spots, though, there may be no practical way to dig without harming tree roots, masonry, or irrigation lines. In those corners, a targeted herbicide treatment can play a limited role.

If you consider this route, stick with products clearly labeled for tough perennial weeds in ornamental beds. Read the label in full, follow the protective clothing advice, and apply only to actively growing foliage on calm, dry days. Shield desirable plants with cardboard or plastic while you spray so droplets land only on the spider plant leaves.

Preventing Spider Plants From Returning

Once you have cleared a bed, the next task is keeping spider plants from creeping straight back in. That means blocking new plantlets, catching strays early, and giving other ornamentals enough space and care to fill the gap.

Block Sources Of New Plantlets

Look beyond the cleared bed for hanging baskets, pots on steps, or neighbors’ plantings that still hold spider plants. Long stems from a container on a rail can reach down into soil below, and wind can drop plantlets into nearby beds. If you want to keep potted spider plants, trim off the baby plants regularly and check that stems are not touching the ground.

Refill The Space With Other Plants

An empty bed after removal is an open invitation for spider plants and other opportunistic species. Plan ahead so you have replacement shrubs, perennials, or groundcovers ready once the bulk of the weeds are gone. Choose plants that suit the light and moisture of the site, and space them close enough that their canopies will knit together over time.

Set A Simple Monitoring Routine

Spider plant control is far easier when you catch new arrivals during the first season. Set a reminder to walk the affected beds every few weeks during the main growing period. Look for narrow, arching leaves in familiar clumps and for fresh runners reaching out from nearby pots or neighbor fences, and pull any spider plant you see on the spot.

Common Spider Plant Control Mistakes And Fixes

Even careful gardeners slip up while dealing with persistent plants. Use the table below to avoid the most common missteps when taking spider plants out of a garden setting.

Problem Likely Cause Better Approach
Patch returns just as thick next year Large roots or plantlets left in the soil Spend more time on fine hand weeding after initial digging.
Spider plants keep appearing under shrubs Runners creeping in from a nearby source Trim stems on potted plants and add edging or a gravel strip.
Smothering does not kill the patch Mulch layer too thin or cardboard breaks down too soon Add extra layers and extend the covered period through one full season.
Solarization has little effect Plastic not clear, soil too dry, or period too short Use clear film, water well, and leave covers on through the hottest stretch.
New weeds fill the cleared bed Soil left bare after removal Plant replacements promptly and maintain a steady mulch layer.

Spider Plant Control Plan You Can Stick To

Removing spider plants from a garden bed is not a one-afternoon task, yet it becomes manageable when you break it into clear steps. Map the infested area, match methods to each corner of the bed, then put in a solid round of digging and smothering, plus solarization if climate and layout allow. After that, refill open soil with plants you actually want and keep a light but steady watch for stray spider plant leaves so the patch does not have a chance to rebuild.
