One of the first steps you take when you are figuring out your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Peru you can estimate when it's the best time to plant oleander by reviewing the USDA zone info.

Planting Calendar for Oleander

Frost tolerance for oleander:	Not tolerant of frost.

Since oleander do not do well in cold weather you really should wait until after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant oleander in Peru is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant oleander and expect a good harvest is probably August. Any later than that and your oleander may not have a chance to fully mature. Starting your oleander indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Peru the average date of last frost happens on April 15. In the coldest months of winter you should expect an average low temperature of -15°F.

Keep in mind that USDA zone info for Peru is not always accurate and the actual date of last frost will vary from year to year. Half of the time in Peru last frost occurs after April 15 so make sure that you are prepared to protect your oleander if you have one of those late frosts.
