how long can i grow til?

what month is too late to plant?

ummm .. u might be able to get a lil sum sum if u do it now ,, some ppl wait until now , so plants stay smaller , they will all bud at the same time ,, when the season changes .... i put mine out may 1st & only had 1 frost & that frost did nothing to them , thank god ....

Yes you can still plant. Where i live some people wait until now to plant there babies in the corn fields,because they had to wait until the farmers spray there fields one last time. As stated before you will get something they just wont get real tall. good luck!
