I live in New Hampshire. Can you please tell me when is the best time to transplant a lavender plant?
Since cold weather may have already occurred in your area, spring would most likely be the best time for transplanting. Here is more info that may help: http://everything-lavender.com/moving-lavender-plants.html
Would appreciate info on growing lavender in the house.
My lavender bushes keep getting sections in the middle dying. At first they change colour--light grey and looks like disease. Then that section dies, not the whole bush just a section. Please help.
It sounds like a fungus issue, which can be alleviated with a fungicide. Neem oil is a good one to try.
I pruned my lavender back as normal, but all the new growth is on the top of the plant, not all over as normal. Why has this happened?
After a time, lavender tends to get very woody at its base. It is not as likely to have new growth on very woody stems. The stems closer to the top are not as woody, so they will produce new growth better.
You may want to consider either replacing the whole plant or starting a regimen of rejuvenation pruning where you remove the oldest stem or two each year to encourage new younger stems to grow from the base.
Can the leaves of fern lavender be used for culinary purposes?
It is a true Lavandula (lavender). So, you should be able to use it in all ways a typical lavender can be used, including culinary.
Can you separate lavender after it has become woody?
You can separate the plant at the ground level. Even if it is woody, as long as the stems at ground level are two separate stems and they have their own root system when split, they can be divided.
Why do my lavender plants look as if they have been flattened in the middle? The plants have all flowered but are not pointing upright but rather spread out as though something has sat in the middle.
This normally happens because the plant do not get quite enough sunlight and they have weak stems. If you can get them more light, that would be helpful. Too little water is another factor.My daisies do this every year when the weather gets hot. After a good soaking, they usually perk right up. It may also help to prune back the plants so that they can produce more bushy growth.
