Rosemary trees
When you bring your tree home from the store or nursery, place it into a larger pot filled with pebble. Make sure that the pot has a hole at the bottom for drainage.
You need to water your rosemary every day or every second day. The plant doesn’t need much, may be half a cup, but constantly. Let the water run right through the soil and drip out into the tray (do not forget to empty it). Some gardeners prefer just to put plants in the sink and water them that way, letting all the water goes down the drain. Then put them back in place with something under to catch more water.
From time to time, give the rosemary a “bath,” gently washing off any dead leaves and other debris. You can let it stay in water for a little while, and then dry up very well.
Like most pot plants, rosemary likes humidity, so you can take the plant to the shower every few weeks, put it on a bathroom counter, close the door, and take a long, steamy shower.
Ensure that there is enough space in the pot; mix the potting soil with sand or vermiculite – or something else to keep it draining well. If your plant spent the whole summer out of door, keep in mind to bring it in before the first frost.
