    Does anybody ever put out fertilizer around very mature trees?I talking about 20 plus yrs old.I told the lady I didn't think it could reach the deep roots well enough.Your thoughts please.

    Simply use a deep root feeder (Lesco has a nice one) and use a liquid with low N. We have always used our 1-1-3 "all organic" and diluted it with water at a 1 - 1 then injected about a cup full per hole. One hole per foot of height of the tree and staggered it around the drip line.

    Deep root injection is really the only way to go on an old tree like that. You could spread a fert around the tree, but you'll most likely feed the grass more than the tree. And doing a foliar app on a 20 year old tree might be difficult to get to the top of it.
    For smaller newer trees, Lesco has a Novex tablets that are really good for transplants, bushes, smaller trees, etc. There's around 500 tablets in a pail and costs $55-60. Put them down once a year!

    There are also tree fertilizer spikes, but I'd go with the deep root. I like Bolster liquid, personally, and sometimes mix some lesco macron 20-20-20, or 23-0-23, depending on the situation. Spreading a dry fert or doing a drench with liquiid around the base of a tree, out to the drip line, will certainly help, but I'd do deep root.

    Deep root is single best thing for a tree.

    Try using a micro-macro mix. Getting the fert to the location were it is needed. With little volitization or waste.

    Hi, use a steel punch bar, poke holes 3-ft apart [ about 6-8inches deep] and pour in 8oz of a granular feed, yes low in nitrogen, especially in the spring and with maples [ to reduce instances of Verticillium Wilt].....start at the "Drip Line" [ the end of the canopy- the furthest branch extensions], work your way inward to the trunk, make 3 or more rings around the trunk of the tree...........and waaaalaa......you've now fed a mature tree, and better than most of the pro's useing a liqued "Deep Root Feeding":waving: .....just for referance I usally get $95-150 per mature treepayup
