    That appears to be powdery mildew. This can be fixed by spraying with neem oil. Just be sure to wash it off before you use it. I don't ever recommend using miraclegro on anything that you intend to consume. It is usually a little overbearing to plants like this anyway. I recommend a good organic potting mix, or adding organic compost to a decent potting mix.

    So, the idea here, is that you want to grow the plant for new shoots. These will have the target flavor without being over bearing.

    The trick here will be pruning. Some years you will want to prune down the older stems to about 6 inches to a foot, so that it can produce new usable shoots. Leave some of the new shoots, and they will be your new main branches, which you will cut in half for a year or two. They will then produce your new shoots.

    You want to harvest the new growth of the plant so that you have growth for next year, bearing in mind that the growth that you leave will produce the year after that. Then you start the process over.

    This will work but choose a Verbena variety that is either low-growing or trailing. It will grow faster than rosemary and might otherwise shade the rosemary and stunt its growth.

    It could be a fungal issue. Without seeing it that would be my first guess from your description. This article may help

    I forgot to include an important tip: don't let the plant dry out in fall. If it goes into winter dehydrated, you are much more likely to lose it.

    You can plant herbs out but you must do it correctly for them to survive. That means slowly introducing them to outdoor conditions by increasing the amount of time outside then the amount of time in the sun while decreasing the amount of water they receive. Transplant on a cloudy day or late afternoon/early evening. If weather is hot and dry, shade them with a cloth or box for several days. Thyme is very hardy but rosemary is only reliably hardy to 30 F. If you will be in a colder environment, bring the rosemary inside for the winter. In marginal areas, insulate/mulch the rosemary for winter.

    In an ideal world, woody plants like the ones you mention will have at least 4 weeks in the ground before first frost. Your plants need time to prepare for winter. I have little hesitation about planting the oregano and lavender as they tolerate cold weather better than rosemary. Overwinter the rosemary indoors as it doesn't tolerate temps below 30 F. Rosemary does much better than the other 2 when grown in containers and indoors. They all need fast-draining soil. If your soil is heavy clay, you will need to amend it with coarse sand, small pebbles or perlite. Soil should dry out, almost completely, between waterings. They are native to semi-desert regions and are used to sandy soil, lots of sun and sparse water. The roots may rot in rich loam.
