Typically potted rosemary should be watered once a week in Summer and once every 2 weeks in the Spring and Fall. Do not water rosemary in Winter as it is in a state of dormancy and additional watering increases the risk of root rot. Well draining soil is just as important for avoiding root rot.
Rosemary pruning can be done anytime during the spring or summer up until four to six weeks before the first frost. Pruning rosemary after this time, or in the fall and winter, can cause the rosemary shrub to focus on growing new, tender growth rather than hardening off and protecting the growth that it has.

Then, lay them down in a single layer across your dehydrator tray/s, with some space between (so the air can circulate for even, quicker drying).

Brewed coffee is highly acidic, so always dilute it before watering your rosemary with it.

An annual prune won’t stop the woody part extending up the plant but it will greatly slow it down. There’s no complicated pruning rules with rosemary, simply cut back the top third of the plant (never into old non-productive wood) with a pair of shears or pruners. Then generally cut the plant to shape.
Rosemary is well suited to container cultivation. When grown outdoors in pots or containers, use an organic 20-20-20 non-acidic liquid fertilizer, applied every other week, while daytime temperatures remain above 50 degrees Fahrenheit.
Most herbs are best just before flowering when the oils are at their peak. Cut the stems in the morning just after the dew dries and before the heat of the day is at its height. Use pruners when harvesting rosemary from mature plants with woody stems. Wash the stems before you begin drying rosemary.

Lay rosemary sprigs on dehydrator trays with plenty of space between each sprig. Dehydrate at very low temperatures, 95°F or 35°C. It will likely take 8 to 10 hours depending on humidity levels. For faster drying remove the leaves from the stems, but that’s totally optional.
Allow them to dry for about 2 weeks, checking regularly to make sure they aren’t becoming moldy or sun-damaged, until they the needles become brittle and begin to fall off. Once dry, separate the sprigs from the tough stems and store the leaves in an airtight container.
