When can I plant Roses in Zone 11b

One of the first steps we take when we are making a decision about our gardening schedule is find our USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

It's possible to figure out when it's possible to plant roses by referring to the USDA zone info for Zone 11b.

The earliest that you can plant roses in Zone 11b is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant roses and expect a good harvest is probably November. You probably don't want to wait any later than that or else your roses may not have a chance to fully mature. If you are starting your roses indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Zone 11b it never frosts. We should expect an average low temperature of 45°F in the coldest months of winter.

Just be sure to remember that our actual date of last frost is just an average because it is based on the USDA zone info for Zone 11b and it can change quite a bit from year to year. Since it never frosts in Zone 11b you do not have to be ready to protect your roses if we have one of those late frosts.
