If your daytime temperature drops below 40F, you will need a heat pack.
I assess every single order during winter. I look at the destination’s weather and plan accordingly for extra security. If I believe that the heatpack will do more damage than good, I cancel and refund. With a heat pack purchase, I wrap the plants with extra insulation in case the mail gets delayed or the heat pack fails to stay warm. This also prevents the plants from getting burned from heat packs.
If any weather is under 35 degrees, day or night, we unfortunately can not guarantee you a live plant upon arrival. The buyer will have to assume all responsibility for any weather related damages. Heat packs are voided once temperature reaches freezing point, even if it claims 3 days of heat.
We will still pack with insulation and to the best of our ability, we just can not provide you with our normal guarantee in this weather.
We would also highly recommend overnight shipping for your order, but as you are taking responsibility for the package that is completely your choice.
