I just got a handful of those primrose plants that are available this time of year and brought them home. They were a bit dry, so i watered them thoroughly and have kept them damp. Of the five plants Ii bought (they had partially opened flowers when I purchased them), only one has properly opened up. The other four have lots of flowers, but they won't open and they are on their way out. It's been a week now and I just don't get it. I get these flowers every year and never had a problem like this. Any ideas?
I am not certain, but I would suspect that the humidity is too low. Low humidity can cause this in other kinds of plants, so I would think it would be a factor here. Is your house drier this year than it has been in year's past? If you have had unusually cold weather where you are, your heater may be drying the air out more than it has in past years.
yes, it has been drier; colder weather, so the woodstove goes a lot; keep a pot of water on it to add moisture, but it must not be enough. thanks!
Last night all of the flowers on my primroses were eaten by deer. Will they rebloom this spring?
Most likely not. They are not known for blooming twice in a season.
I live in northern New Jersey and would like to know if it is too early to plant primrose plants in the ground now (April)? If so, when is a good time to plant?
Now is a good time. They can take the little bit of cold that could possibly occur from now till last frost.
I have planted showy pink primroses, but on the first two plants around the base, the leaves are turning yellow and are wilting. Is this a result of root rot? The soil is sandy and dries out easily. I've fertilized, but no mulch. What should I do?
This often signals stress of some kind, with many causes.
These articles will help determine the cause:
You may want to consider amending the sandy soil. This article will help with that: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/amending-sandy-soil.htm
When is the best time to split and transplant primroses?
Divide and transplant them in the fall. Each division should have at least two shoots (five shoots are ideal) and plenty of roots. Replant your root divisions as soon as possible.
I planted a Primrose plant two years age and didn't realize it was so aggressive. I have moved most of it. How can I kill the rest?
They are very evasive ground covers. I had the same problem. Here's what I did: Using spade - dig up as much of the root system as you can. Do this until all are removed. don't leave in to flower & seed or you will continue to have a problem. You just have to keep doing until all are done & gone. It's a task.
My primrose is done blooming and I would like to cut back the foliage to make room for the plants around it.
If you cut back green foliage, it can harm the plant's ability to build energy for surviving the winter and blooming next year. You should only cut back yellow leaves, as these are dead and no longer help the plant build energy.
