Q.pumpkins
I started pumpkins from seed, germinated very quickly and now they are getting very spindly. Is there any way i can stop this. I live in Pennsylvania and snow is falling. I was told my a farmer to start in very early spring indoors. My garden will not be ready until May. What can i do? The plants right now are very healthy looking only tall and spindly. Thank you, Jane

Pumpkin seeds should be started about 2 to 3 weeks before the last frost date. Those dates for you are in the range of April 13 to May 16th--you need to follow the weather trends.
You can add additional light to the seedlings, but you may want to start some new seeds to ensure you have healthy seedlings to plant outdoors.
Use grow lights and rotate the plants for even growth.
