Planting in summertime or winter is not advisable for most plants , unless implant a more launch sized industrial plant .
To set container - grown plant : develop planting jam with appropriate depth and space between . irrigate the flora thoroughly and let the excess water drainpipe before cautiously removing from the container . Carefully untie the ancestor ball and place the flora in the kettle of fish , working soil around the roots as you fill . If the plant is extremely ancestor tie , freestanding rootage with finger .
