    Yes, you will want to replace fresh woodchips with soil or plant in a different area. They have an extremely high carbon to nitrogen ratio which will render the area unsuitable for plants to grow. All wood chips should be seasoned before using, OR if you are just using this as a VERY thin top layer, then it can work. You will notice that even grass will have a hard time growing in that area, which will let you know that the area is currently unsuitable for planting. After a year or so, you may start to see growth come out of the now semi-composted chips.

    Once the roots are removed, it would be helpful to do a soil test before amending and planting. You can contact your local extension service for this.

    You can enrich the soil with compost and other amendments to prepare a bed for roses. These articles will help:

    I only found a 'Chelsea' climbing rose and a 'Chelsea Belle' miniature rose. I doubt he wanted either of those. The famed breeder, David Austin, introduced his first roses in Chelsea, England, and flower shows are held their regularly. It's possible he referred to a Chelsea winning rose.
    I'd advise contacting your nearest rose society and seeing if they know of something more specific.

    Leaf scorch is usually due to going through a period of high temperatures or reflected sunlight hitting the leaves. The rosebushes simply cannot move enough fluid to the extreme outer portions of the leaves to keep them from burning up during times of high temps outside. Keep the roses watered and things should improve once cooler weather sets in. If your rosebushes are planted where they get total sun and heat contact for much of the day, this is likely the problem. One way to avoid the leaf burn is to erect something that will give the roses some shade for part of the day during the hotter times.

    Another possibility is when water or pesticide sprays have been allowed to pool on the leaf edges during the hotter times of the day. The water or sprays remaining on the leaves acts like a magnifying glass and burns the foliage with the sun's rays.

    This looks like a fungal infection although it may be superimposed on leaf edges that browned due to drought or extreme heat. If the entire plant is affected then use a systemic fungicide from a garden center. There are DIY formulations that are best left to preventing, not curing a fungal problem.

    The best time to prune roses is in early spring, right before they start to leaf out.

    The temps given are not really all that high. However if the rosebushes are located where they get direct sun at the most intense times of sun heat during the day, they could be under stress. Keeping them well watered is more important than feeding them too much at such times. Watering them with water that has a product called Super Thrive in the water helps them deal with all kinds of stresses and shocks, thus I recommend it if you can get it. I get the large sized bottle of it on Ebay for a good price. The other thing you can do is to provide a lightly colored shade structure for them during the hottest time of the day. Such as white of light colored umbrellas tied to poles sunk in the ground by the rosebushes. The light coloring helps reflect the most intense rays of the sun. Dark colored ones will increase radiant heat upon the roses, which you do not want.
