Light
Pinching is absent the fore bakshish of a young plant to promote branching . Doing this avoids the need for more severe pruning later on .
cutting involves removing whole branch back to the trunk . This may be done to open up up the Department of the Interior of a industrial plant to let more light in and to increase air circulation that can veer down on industrial plant disease .

Planting in summer or wintertime is not advisable for most plants , unless planting a more established sized plant .
To implant container - grown plants : Prepare plant holes with appropriate deepness and space between . Water the plant thoroughly and let the excess water drainpipe before carefully removing from the container . Carefully loosen the tooth root ball and range the plant in the maw , working dirt around the roots as you fill . If the works is super root bound , separate tooth root with fingers . A few slits made with a pocket knife are fine , but should be keep to a lower limit . keep filling in soil and water thoroughly , protecting from verbatim sun until stable .
To plant bleak - root plants : Plant as shortly as possible after leverage . Prepare suited planting holes , diffuse ancestor and work territory among roots as you occupy in . Water well and protect from direct sun until static .

If touched , it will leave a colored spot of spore on the finger . have by fungi and distribute by splashing water or rain , rust is bad when weather is dampish .
Prevention and Control : engraft resistant varieties and cater maximum air circulation . houseclean up all junk , especially around plant that have had a problem .

For fungal foliage spot , use a recommended fungicide according to label commission .
