Can You Ship Plants to California? Rules, Labels, and Inspections

Shipping plants to California is legal, but every shipment is inspected and has to clear the state’s quarantine rules before it reaches the recipient. The plant must be pest-free, the package must be labeled with specific information, the soil (if any) has to meet quarantine standards, and the species itself cannot appear on a prohibited or quarantined list. California screens shipments at 16 highway border stations and at airport and mail facilities, and inspectors reject more than 82,000 lots of plant material each year.¹

Check Whether Your Plant Can Enter California at All

Before you worry about paperwork, confirm the species is actually allowed. California maintains a noxious weed list under Section 4500 of the California Code of Regulations that runs to well over a hundred species, including some ornamentals people don’t realize are regulated: giant reed, tree of heaven, Scotch broom, multiple knapweeds and thistles, yellow nutsedge, alligatorweed, and several dodders. If a plant appears on that list, it cannot legally be shipped into the state.

Separate from the noxious weed list, California runs active quarantines targeting specific pests and the plants that carry them. As of early 2026, exterior quarantines cover Japanese beetles, cotton jassid, guava root-knot nematode, and others. Interior quarantines restrict movement within the state for Caribbean fruit fly, peach fruit fly, emerald ash borer, and citrus yellow vein clearing virus, among others.²

Citrus

Citrus gets its own layer of restriction. Huanglongbing (citrus greening) has been spreading through the United States for years, and the federal government regulates interstate movement of citrus nursery stock, budwood, and other propagative material from quarantined areas under 7 CFR 301.76.³ California also maintains its own citrus pest quarantine. In practice, shipping a citrus tree into California from most of the country is either prohibited outright or carries certification and treatment requirements too heavy for casual shippers. The CDFA strongly discourages private individuals from bringing citrus plants into the state.⁴

Sudden Oak Death Host Plants

Sudden oak death, caused by Phytophthora ramorum, has killed millions of trees in California’s coastal forests. APHIS regulates host plant movement from nurseries and quarantine areas under 7 CFR 301.92, and California has a statewide quarantine.⁵ Nurseries in affected areas must follow compliance protocols and have plants inspected before any shipment leaves.⁶

The Soil Problem

Soil is where most shipments fail. California’s Japanese beetle exterior quarantine treats all growing media as a potential carrier and prohibits soil from quarantined areas unless it is commercially packaged.⁷ The quarantine area covers much of the eastern United States and, as of February 2026, includes Oregon.²

Plants shipped with soil from a quarantined area can still enter California, but only through two narrow paths:

A treatment certificate from an authorized agricultural official in the originating state, certifying that the rooted plants were treated to control Japanese beetle according to the U.S. Domestic Japanese Beetle Harmonization Plan before shipment.
Approved greenhouse production: plants grown in a certified Japanese beetle-free greenhouse using sterilized growing media, with all stock planted bareroot into the approved medium.⁷

If you are shipping from anywhere east of the Rockies, the safest approach is bare-root, or repotted in fresh, commercially packaged potting mix right before shipping. Garden soil and backyard dirt will almost certainly get a shipment rejected.

How to Label the Package

California law requires every plant shipment entering the state to be clearly labeled on the outside of the package with four pieces of information:

The shipper’s name and address.
The recipient’s name, or the name of their agent.
Where the contents were grown: the country, state, or territory of origin.
A description of the contents, such as “plants” or “plant material.”⁸

Labels must be legible and placed where an inspector can see them without opening the package. Missing or incomplete labeling is a common reason shipments get flagged for additional scrutiny.

For packaging, use clean, new containers and supplies. If you ship through the U.S. Postal Service, roots or cut ends have to be wrapped in moist packing material inside a waterproof lining (waxed kraft paper or plastic wrap) to prevent leakage, and the outer box needs a similar lining. Plants with thorns or sharp points need puncture-proof packaging.⁹ FedEx and UPS have their own packaging guidelines, but California’s labeling rules apply regardless of carrier.

Documentation for Nursery and Commercial Shipments

Commercial or nursery-scale shipments typically need a phytosanitary certificate issued by an authorized agricultural official in the originating state. This is a state-issued certificate, not the federal PPQ Form 577, which covers exports to foreign countries. State phytosanitary certificates follow a similar format but are issued under state authority.¹⁰ The certificate confirms the plants were inspected and found free of regulated pests and diseases. Fees vary by state but generally run between $6 and $30 per certificate.

Some shipments need more than that. APHIS requires a permit, applied for through the eFile system at efile.aphis.usda.gov, for interstate movement of plant pests, biological control organisms, parasitic plants, and federally listed noxious weeds.¹¹ Plants subject to specific California quarantines may also need a state-level permit from the CDFA.¹²

Moving Houseplants With You to California

If you are relocating and want to bring houseplants, the CDFA has specific requirements. Plants must have been grown entirely indoors (in a house or enclosed greenhouse) and potted in commercially packaged, sterile potting mix. Plants that spent time outdoors or sit in backyard soil don’t qualify.⁴

At the border station, declare your plants and make them accessible for inspection. The inspector will check for visible pests and signs of disease, and any plant that looks infested or unhealthy can be confiscated on the spot. If you are using a moving company, put “house plants” at the top of your inventory list and have the movers store the plants near the van doors so the inspector can reach them without unloading everything.⁴

Even for personal moves, the CDFA strongly discourages bringing citrus plants, pine trees, and fruit or nut trees into the state. You can technically bring them if you satisfy every applicable quarantine requirement, but the compliance burden is heavy enough that most people are better off leaving those behind.⁴

What Happens If a Shipment Fails Inspection

When an inspector finds a problem (pests, disease symptoms, a prohibited species, missing documentation, or soil that doesn’t meet quarantine standards) the consequences move quickly. Under California Food and Agricultural Code Section 6461.5, an inspector who finds an infested or infected shipment can order it destroyed immediately, on the spot, at the owner’s expense.¹³ There is no appeal at the border. If the inspector has reasonable cause to believe a shipment may be infested, destruction is authorized even without confirmed pest identification.

Items that violate a federal quarantine are subject to seizure and destruction to the same extent as if the violation had originated within California.¹⁴ For international shipments, federal civil penalties can reach $1,000 for a first offense involving personal quantities and substantially more for commercial ones.¹⁵

Buying Plants Online for Delivery in California

Ordering from an online retailer doesn’t exempt a shipment from any of these rules. The package still needs proper labeling, the plants still have to be free of pests, and quarantine restrictions still apply. Established online nurseries typically handle compliance on their end: they know which plants they can and cannot ship to California, they use appropriate growing media, and they include the required documentation. Many list California among states with shipping restrictions.

Trouble tends to come from casual sellers on marketplace platforms, small hobbyist operations, and international purchases. If a seller ships a prohibited plant to a California address and it gets caught at inspection, the shipment is destroyed and the buyer loses whatever they paid. The CDFA doesn’t distinguish between a commercial nursery’s mistake and a hobbyist’s ignorance; the plant material gets the same treatment either way. Before ordering, check whether the species appears on a California quarantine list or the noxious weed register, and confirm the seller ships in compliance with California requirements.
