No fertilizer.

Scissors work only if trimming green shoots. Get some pruners, even inexpensive pruners will work well if you don't do much hand trimming. Never trim off more than 1/3 of the living plant material. With lavender, no pruning is required. I would only trim out the dead material and minor pruning (if any!) for shape.

I'm surprised that the rose and a lavender would do well together. Roses like more moisture and much richer soil than the lavender. Lavenders prefer conditions that are more similar to a rock garden than a rose bed.

Hi fata..
Thank you for helping me with this. I planted them together because I was told that lavender and roses go well together.

Garden shears are the quickest way to trim lavender.
Just clip all over it and remove old flower stems and about half of the newest growth. Don't cut into old wood as it seldom regenerates in lavender. I'd disagree with Fata (very rare:)) over lavender not needing pruning. It's one shrub I would say is much improved by clipping to get rid of the dead flower stalks.

Hi flora, thank you for your suggestion. Okay, I won't cut into the old wood. What is your opinion on planting the roses with the lavendar? I always read that they went well together. This is all new to me and I'm not sure what to do? Thanks again.

No particular opinion on roses with lavender, except they are a common combo over here in traditional style gardens. Although lavender is a Mediterranean plant it is quite happy in the average damp English garden. Not sure what is meant by 'Go well together'. Does that mean they are an aesthetically pleasing combination or a traditional combination? Or is there supposed to be some sort of 'companion planting' effect? The link shows some examples.

Here is a link that might be useful: Lavender and roses

thx flora, actually what I was trying to say is can lavendar be planted them in the same soil as the roses? We get a lot of rain during the winter so the soil is moist but has good drainage. I think lavendar and roses look beautiful together. Thx for the link, what a gorgeous garden.

I have Hidcote lavender, in front of my roses, and they've been very happy together. I did it mainly to keep out the deer (which works pretty well) but also because they look so pretty together.

Last spring, I didn't trim my Hidcote lavender, at all. It was a wet and cold spring, and we kept getting late frosts. My mom cut back her butterfly bush, too early, and it died...so I was hesitant to trim anything, too soon.

One day, I noticed all the old blooms/stems had fallen off the lavender and new flowers were forming. So, I don't think you have to trim lavender at all, but the choice is yours :)

Maybe it depends on your climate. I pass a front garden every day on may way to work which has a lavender hedge the whole length of the frontage. The house has obviously changed hands and the new oweners did not clipped it last year. The dead flower stalks have persisted all winter and are still there now looking very scruffy.
