The last month that you can plant tropical water plants and expect a good harvest is probably August. You probably don't want to wait any later than that or else your tropical water plants may not have a chance to grow to maturity. If you are starting your tropical water plants indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

The average date of last frost is March 15 in Zone 8a. We can expect an average low temperature of 10°F in the coldest months of winter.

Remember that our actual date of last frost is just an average because it is based on the USDA zone info for Zone 8a and it changes from year to year. Half of the time in Zone 8a we get a frost after March 15 so make sure that you are prepared to protect your tropical water plants if we have a surprise late frost.
