My sisso tree has indications of salt burn ( leaves fade and then burn around edges) I have been deep watering for a few weeks noy (overnight drip) but the new growth swhow fading and burning at the edges as before. Should I add Iron? I added Gypsum about 3 weeks ago to amend the clay soil.

Dalbergia sissoo is native to the foothills of the Himalayas of India, Pakistan and Nepal. It is primarily found growing along river banks. Soils range from pure sand and gravel to rich alluvium of river banks, but sissoo can grow in slightly saline soils. What you are seeing is not necessarily salt burn (since the trees can grow in slightly saline soils) but may be a symptom of insufficient water. Continue to water deeply, which should improve your rosewood's overall health. You didn't say how long the tree has been planted - could be that it is still trying to adjust to your soil and the exposure to sunshine that it is receiving. If it is newly planted, give it more time to become established. If it has been in the ground for 2 or more years, you might want to have your soil tested to see exactly which nutrients it is lacking (or has an over-abundance of). The results will guide you in determining which, if any, elements you should be applying.

Best wishes with your landscape!
