As a gardening and landscaping expert , I can partake my knowledge and experiences regarding the optimal temperature for get lemon grass . Lemongrass is a tropic plant that thrives in long , hot grow seasons . It is well - suited for areas with soft winters and systematically warm temperatures .

To determine the temperature that is too cold for lemongrass , it is important to consider the plant ’s innate habitat and its tolerance to cold precondition . Lemongrass is native to tropic area such as Southeast Asia , where it enjoys quick and humid climates throughout the year .

In general , lemon grass can tolerate temperatures as low as 40 degrees Fahrenheit ( 4 grade Celsius ) . However , it is important to note that prolonged photograph to temperatures below this threshold can potentially damage or even defeat the plant . Therefore , it is advisable to provide some protection or take necessary amount to ensure the selection of lemongrass oil during colder periods .

If you survive in an area with mild winter , where temperatures seldom degenerate below 40 degrees Fahrenheit , you’re able to stay raise lemon grass throughout the year without much vexation . However , if you live colder temperatures , it becomes crucial to take footstep to protect the plant .

One effective method of protecting lemongrass from insensate temperature is by providing insulation . This can be done by mulch around the al-Qaeda of the plant using organic materials such as chaff or leaves .

Sudden swing in temperature or protract periods of utmost frigidness can gravel a risk to lemongrass , and additional touchstone may be necessary to ensure its well - being .

In my personal experience , I have successfully mature lemon grass in a area with mild winters . However , during particularly cold spell , I have mark some damage to the flora , such as browning or wilting of the foliage . By allow detachment and wreak potted lemongrass indoors during these moth-eaten periods , I have been able-bodied to protect the plant and secure their natural selection .

The temperature that is too insensate for lemongrass is loosely below 40 degrees Fahrenheit ( 4 degrees Celsius ) . While lemon grass can tolerate colder temperature for short geological period , prolonged vulnerability to extreme common cold can be damaging to the plant ’s health . take away protective quantity such as insulation and bring potted lemon grass indoors can help assure its survival during colder periods .
