Planting in summer or winter is not advisable for most plants , unless plant a more established sized plant .
To constitute container - grow plants : Prepare planting holes with appropriate depth and infinite between . irrigate the plant thoroughly and lease the excess water drain before carefully removing from the container . cautiously loosen the theme ball and send the plant in the hole , work soil around the roots as you take .
