One of the first steps you take when you are estimating 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.

It's a good idea to estimate when it's the best time to plant guara by reviewing the USDA zone info for Phoenix.

Planting Calendar for Guara

Frost tolerance for guara:	Not tolerant of frost.
When to plant:	After the last frost when the weather gets warmer.

Guara do not do well in cold weather which means that you have to wait until it warms up after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant guara in Phoenix 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 guara and expect a good harvest is probably August. You probably don't want to wait any later than that or else your guara may not have a chance to grow to maturity. If you are starting your guara indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Phoenix the average date of last frost happens on March 15. You can expect an average low temperature of 10°F in the coldest months of winter.

Remember that the actual date of last frost is just an average because it is based on the USDA zone info for Phoenix and it can change quite a bit from year to year. Half of the time in Phoenix you get a frost after March 15 so make sure that you are prepared to protect your guara in the event of one of those late frosts.
