Hi. This is Yolanda Vanveen, and in this segment, we're going to talk about how to prune lavender. My lavender bush is one of the highlights of my garden. The butterflies just love it, and I love the fragrance. But I have found over the years, that it's very important to prune your lavender. Because if you just leave it wild, it will grow very lanky. And then in the end you'll just have a lot of wood and very few flowers. So by starting with a very young plant, and pruning it every year, in the end you'll get lots more flowers for many more years. And my rule of thumb is, if it's an old established lavender, that's been there for fifty years and it's all wood, and just a few flowers, you can try trimming it back or pruning it back, but you're really never going to get a lot of flowers. Because they only live for a certain amount of time. And so, it's almost better to just dig it out and start with a new plant. Because you can't really save old plants. You're not going to get a lot of flowers. So, when you have a young plant, the rule of thumb is to prune a third of the plant down each year. And the best time to prune it is when it's done blooming in the middle of winter. So, by just cutting all the branches down about one third of the size, it will fill it up. And then even on the side branches, if you just trim out about one third of the branches, just to the main trunk, you'll find that they will fill in and be much more lush the next year. And never trim it all the way to the ground, or too far down into the wood. You only want to trim where there is new growth. You don't want to trim into the woody area of the stem, because really, if you trim into that wood, it's pretty much just going to die right there. You only want to trim the new growth. And by just cutting out some of the medusa type branches too and make it more of a ball, it will grow very full and circular the next year, and you'll get even more flowers on your lavender plant.
