|I planted lavender 3 years ago. It has not been pruned and is spindly and brown at the base. Can I fix it or do I start again with new plants? My|
|Lavender will get woody if you don't prune it back on a regular basis. Usually we recommend trimming it immediately after it has finished flowering and pruning again the following spring just as new growth begins. This will keep it full and bushy. If your plants have bare stems pruning won't make them leaf out again. I'd suggest replacing them with healthy new plants and trimming them regularly to keep them full and bushy.
Now that your irises have finished flowering you can cut off the flower stems down to the level of the foliage. Enjoy your garden.
