How can I bring this dry ground (under a tree) back to life?

Hi all

We moved into a house a couple of months back that had been left empty for a long period.  In that period there was a tree in the garden that had completely overgrown and in high winds looked very dangerous.  The tree also blocked out 50% of the garden light too.  The Tree was bigger than the house and sometimes leans towards the house in heavy winds.  With safety in mind and the fact that we want to reclaim our garden light we took the decision to cut the tree down.  I am aware that some people will criticise me for cutting the tree down but in mitigation, we have planted 6 more (for privacy).  So, on to the subject matter...One can see that the tree is in the far right of the Garden.  You can also see that the left of the garden, the grass grows fine.  Taking into account that the tree was huge there is a large patch under the tree that is bone dry.  In fact, on warm days if the wind gets up dirt dust blows everywhere.  I'm not certain why this patch under the tree is so dry.  Is it because rain couldn't get to the ground (because the tree was so huge)? or is it the fact that the tree was so large it drank all the rain water (leaving none for the grass)?.  Turn back the clock for 6 weeks and under that tree was nothing but a horrible lawn of moss.  I sprinkled some evergreen thingy on it and now six weeks later I am left with this horrible patch of dry ground.  It's so dry it is even cracked (look at the pictures).  So, in the next few days, the remainder of the tree will be cut down and I will be left with this arid dry patch.  What do I have to do to get this ground back suitable for growing grass on it?  I don't want to waste water by hosing it repeatedly so I had a Eureka idea of diverting the rainwater from my drain pipe onto this bit of land to completely saturate it.  Is this a good idea?  Simply, all I want to do is grow nothing more spectacular than grass seed.
Thanks in advance all.

    The tree will have used all of the goodness from the soil in that area, so assuming you have already removed the tree and roots, you need to dig the ground over and incorporate as much organic matter as possible, with well-rotted manure being my choice.  You'll need a 15cm layer which you then dig or rotavate in.
    It is the organic matter in the soil which retains most of the water, so simply watering it won't do the business.

    Hi Bob

    Thank you for your answer.  Much appreciated... I will remove the stump to ground level but it is too big a job to remove the roots.  They literally go under next doors fence.  I was planning on just leaving the roots in.  Assuming I dig over the area with Manure etc would this be sufficient (If I left the roots in the ground)?

    Yes, the stump will slowly rot over time, if you don't want to have it ground out, it won't be taking any more nutrients from the ground (in fact, it will start adding it as fungi slowly break down the wood, but that will take several years.)  It will also become a home for beneficial insects, such as beetles.  If you dig-in organic matter now, the soil should be in pretty good condition for raking over and sowing in autumn.

    Bear in mind that if the tree roots are still alive it could sprout from around the stump and/or sucker from the roots. Mowing grass could also be tricky if there are roots at the surface. Organic matter will improve the soil for whatever you plant.

    It does depend what tree it was, some can sprout back after being reduced to a stump, so keep a close eye on that just in case. If it starts to reshoot, you may end up having to get it taken out. If it is still fairly shady there (from the surrounding trees), once you have prepared the ground as Bob advises, choose a grass seed mix that can cope with some shade.

    Apocryphal story - my parents 1940’s house has a mainly lawned garden. After a bad drought year, the ground level dropped to reveal old tree stumps that had obviously just been taken back to ground level and turfed over. Incredibly, they started sprouting - we couldn’t believe it!! They had to get the entire lawn dug up and relaid.

    It is possible (depending on species of tree) that it could resprout at ground level. Ash and hazel are particularly likely to do this. To avoid the problem you need to kill the remains of the tree.

    My preferred method would be to remove the trunk to ground level and then use a stump grinder to remove the stump plus as much surrounding root as possible. This method requires heavy duty equipment and IMO is best left to the professionals.

    Failing this you can apply stump killer to the (ground level) stump which (hopefully) will kill the remains of the tree and the stump and roots will eventually rot.

    My suggestion is to go with the stump grinder and leave the whole area for a bit so the remaining roots have a chance to soften and rot. In autumn you could lay the 6" of well rotted manure suggested by Bob. Some of it will work into the soil over winter courtesy of worms etc.

    Then next spring the whole area will probably be ready to rotavate / dig, compact and sow grass seed.

    Unless it is cool and wet where you are - now is not the best time of year to be sowing grass seed or laying turf. Autumn and spring is the time for those jobs.

    Taking all these fantastic comments into account I would like to have my cake and eat it. (Instead of manure etc) is there a non smelly, chemical, shop bought equivalent I could use? I ask because we don’t really want to smell manure etc over our barby… this summer. Am I asking for the imposible?

    Well-rotted manure doesn't stink (it might have a mild composty smell). The manure that you can buy in bags from the garden centre should be fine.

    Well rotted manure doesn't smell that much (it's more an earthy sort of smell) especially when partially dug in. (Or completely if you have energy).

    Well rotted manure (the bagged kind) shouldn't smell once it's been down for a couple of days. It's really best to get some organic matter into that patch that chemicals just won't do. You could even put your grass clippings as well (as long as they haven't been treated) on the surface which will eventually rot down.
