Root damage

I'm pretty sure that by putting old horse manure on our trees, shrubs & cactus have burnt the roots. Is there any way to correct this. Leaves are turning yellow to brown and cactus is wilting. Helps please!

    How old?  The cactus may alread be beyond help.  How big?  How easly can you clean the roots and replant?  Wilted cactus are usually unsaveable.  For the trees and shrubs, pray for rain.
     location: Surrey Hills, England, ex-woodland acidic sand.

    Cacti don't need manure.  As @bede says, how old is "old "re your trees/shrubs ? Location, aspect, age of trees/shrubs. watering regime - all will have an effect.

     Oleander and one citrus tree which are fairly new are having issues.
    Would drowning them with water help? Right now they get watered once a week unless I water more.

    Again your location will make a difference. Oleander and Citrus aren't generally considered as everyday trees in the UK.  Not to say that they cannot thrive and do well here given the correct aspect and conditions.
    Little point drowning them if you are unsure what the actual problem is.  A photo or 2 may help posters to offer some advice as will an idea of where and in what your problem  trees are planted. 
    The more info you give, the better chance of getting some help :)

    If the manure was mixed with lots of straw and rotted down to a sweet, crumbly brown mass, it is highly unlikely that it has caused any harm and should have done much good.

    I live in north Baja Mexico on the eastern side of the peninsula...desert environment...humid and hot during the Summer. I mixed the manure with the soil...nothing more.

    Ah, that's rather different. I think it would be a really good idea to research local methods of cultivation. Members of this forum always do their best but I'm not sure how many of us know a great deal about your area of Mexico.
