The basis of successful rose growing, is planting the rose bush properly in the first place.
A simple enough task, but needs to be done methodically - second nature to seasoned gardeners.
A bit of care and attention when planting your rose bushes will go a long
way to having a successful rose.
Here is how to Plant a Rose Bush.....
First make a really good planting compost - which will give you the best results and quick rooting - prepare a planting mixture of granulated peat or multi-purpose potting compost (not soil based) and soil in equal proportions. You will need about one shovelful per plant.
Add one handful of bonemeal per plant to the compost (as you plant the rose bush). Carry out the planting on a frost-free day and make sure the soil is not waterlogged.
Dig the holes large enough so that you can spread to roots out. It should also be deep enough for the budding union (from which the shoots grow) to be located with the top of the rootstock union level with the the soil surface. Cut away any weak, twiggy, or diseased growth down to a healthy bud, cut back long, thick roots by about two thirds to encourage fine feeding roots to sprout out. The thick roots are only for anchorage. If the bushes look dry, soak them in water for an hour or so.
Some writers - rather than gardeners - suggest that the rootstock should be just proud of the soil. Far better that it is just below the soil surface. This will ensure a good succession of basal shoots over the years.
Place the rose bush in the middle of the planting hole and, holding it upright, spread the roots out evenly without straining any of them into unnatural positions. If, as is often the case, they all run in one direction, try to twist some of the roots into an all-round position, to ensure a firmly planted rose bush. Check the depth of the budding union with a cane placed across the hole and adjust the depth as necessary. Put in your shovelful of planting mixture, gently shake the rosebush to get the compost settled amongst the roots, and firm it round the roots. Fill the hole with soil and tread it firmly (but not so heavily on heavy soils as to expel the air). Water well if the soil is dry. Firm the soil again after frosts during the winter and again in early spring. This will make sure that the planting hole soil - which may have loosened up during frosty periods, will be firm on top of the roots.
