Question
We recently removed a very large pine tree from the corner of our house because its needles were clogging our gutters and those of our neighbor.
Although we did have the stump removed entirely I want to plant some shrubs and flowers in the empty
4'x5' area. I had heard that there is a problem getting things to grow where a pine tree has been planted. Is this true and if so, what can I do to get the soil prepared for planting perennials and a few annuals? I don't have much of a green thumb but can follow directions very well.
Also I am thinking of planting a burgundy color leaved bush or small tree. I see it in my area but can't seem to find out what it is called and whether it is a drawrf tree or a bush. Can you tell from my description what it is called?

Thanks,

Michele

Answer
Hi Michele,

Pine trees through their fallen needles cause the soil to become very acidic and the needles also secrete molybdenum into the soil.  all of this makes the soil an harsh environment for other plant species to establish in.

To improve the soil rake up and remove as many needles as you can from the soil.  

Apply lime to the soil based on the product application rates and then mechanically cultivate the soil to a depth of 30cm incorporating the lime deep into the soil.

Allow the soil to settle for a week or two then apply a base dressing of balanced granular fertilise e.g. 7:7:7.

Allow weeds to grow in the border during the summer.

At the end of the summer kill off the weeds with a systemic herbicide such as RoundUp.

Cultivate the soil again to a depth of 30cm.

Allow to settle for another week.

Plant up the border after that.


Hope all this helps, and please do let me know how you get on.
