How to Ship Plants Safely in Hot & Cold Weather
A practical guide to packing live plants, using heat or cold packs, choosing service levels, and timing shipments in risky weather.
A plant that arrives cooked, frozen, or crushed can turn a good sale into a refund. Safe shipping is a repeatable process: check the weather, pack tightly, protect against temperature swings, and minimize transit time.
This guide covers packing, thermal protection, shipping restrictions, carrier choices, and ship-day timing. Build the cost of good packaging into your shipping price from the start.
- 1
Check the weather on both ends before you ship
Check the forecast at origin, destination, and likely transit points. Below freezing and above roughly 85°F are the danger zones. In extreme weather, delay shipment or upgrade speed. For interstate shipments, also check whether the plant, growing medium, or destination has agricultural restrictions.
- 2
Prep the plant before it goes in the box
Water lightly a day or two before shipping. Keep roots moist, not soggy. Secure the pot or bare roots so soil and media do not shift, sleeve the foliage, and stabilize tall plants. The goal is simple: nothing moves when the box is handled.
- 3
Choose the right box and insulation
Use a sturdy box that is snug but still leaves room for cushioning. In hot or cold weather, line the walls with thermal bubble wrap or foam panels. Fill gaps with paper so the plant cannot shift. In cold weather, do not add ventilation holes.
- 4
Add a heat or cold pack, and never let it touch the plant
In cold weather, add a commercial heat pack rated for your transit time. In extreme heat, use a cold/gel pack. Never let either pack touch the plant directly. Attach it to an inside wall and separate it from foliage with paper or cardboard.
- 5
Pick a carrier and service level for the season
USPS Priority Mail is common for small plants and cuttings, usually 2–3 days with tracking. USPS treats plants as mailable in the U.S. when not blocked by agricultural or conservation restrictions, and a live/perishable handling fee may apply. In heat, freeze, peak holiday volume, or for high-value plants, use the fastest service you can justify.
- 6
Time your ship day: early week, early day
Ship Monday through Wednesday and drop off early so the package starts moving. Avoid Friday shipments, weekends, and holidays when plants can sit in facilities during heat or cold.
