KERNERSVILLE, N.C. -- Even though we're well into spring, freezing temperatures are sticking around and impacting the spring planting season.

Staff at the Kernersville Paul J. Ciener Botanical Garden wrapped their most vulnerable and rare plants in frost cloth last week, as a precaution ahead of freezing temperatures.

Experts recommend you do the same for your plants at home, and hold off on planting a summer crop until at least May 1.

"This time of year it's still in that kind of vulnerable period so hold off on tomatoes and petunias and marigolds because I've seen them for sale, what you do want to plant are cool season vegetables -- so your lettuce, broccolli, cabbage, and then of course hearty plants too that have been outdoors," said Adrienne Roethling, the director of curation at the garden.

If you plan to shop at a garden center in the next few weeks, experts recommend you stay out of the greenhouse and only buy plants that are being kept outside.
