Sep 18, This technique is best done in the spring since it will send off lots of new growth and the long growing season to follow will help it. But general pruning of rosemary can be done throughout the growing season and right into early fall. My plants get lightly pruned during the spring and summer, since I cut rosemary for use in recipes all year. Cut back by 1/3 to shape your plant.
Take the likely-looking" pieces and stick them into the ground 1" or so. About 50% will root without any further assistance other than watering if its really, really dry. Then you'll have a bunch of little rosemarys to train or to pot up and give as gifts.
Same works for lavender, forsythia, etc, etc. 1.
Start rosemary cuttings in early summer when the parent plant has few flowers. Water the parent plant to a 4-inch depth the night before gathering the cuttings to ensure the stems and foliage.
I have a 6 yr old plant that I think is getting a bit rank & stalky.
Any advice would be appreciated. May 01, Rosemary, like many shrubs, won't grow back from portions of underground roots, so I don't need to dig a massive hole. Once the stump was out, all that remained was to fork over the edges of the hole, add a bucketful or two of our home-made compost to replenish the soil, and lo! and behold, ready for replanting. But not with another rosemary!Estimated Reading Time: 3 mins.
