Q.tulips coming up before last hard frost
I live in SW New Hampshire, and planted about 100 tulips this past October. We had a mild winter, and now my tulips are coming up (about 2-4″ tall now). Should I be concerned about evening temps being 32 degrees? Should I cover them? Thank you for any advice!
Sincerely,
Casey

In most cases your tulips and spring bulbs will not be effected by dips in temperatures.
If the there is an extended freeze or if temperatures in the daytime remain below 29 degrees F. they could suffer some damage.
You can cover the plants overnight if you wish.
Even if the plants are effected by the freeze your bulbs will recover and bloom again next year.
