Question
Hi, I have bought some small acorn plants and want to try my hand at them. I am a beginner. But unfortunately I am not able to plant them in the ground.  I will need to put them in a large pot.  I do have room for the vine to grow so that is not a problem.  I have not been able to see a picture/info of how this might work or what I should do...do I just plant it and let it go? do I need to give it something to grow up?  Do the vines root as they grow? Should I plant the 2 small plants in the same pot or separate but next to each other?
Sorry for so many questions but every I have looked has not answered my questions. Thank you!
Terri

Answer
Dear Terri:

Plant the acorn squash in individual 3 to 5 gallon containers.  The container must have drainage holes in the bottom.  Since an acorn squash can grow to a 3 to 5 pound size, you must allow space and a bed of some sort for their support as they grow.  Straw, crumpled newspapers in a box,  or Styrofoam pellets packing material surrounding the containers will provide adequate support.  You can also use a trellis for the vines, but be aware that it must be strong enough to support the weight of your squashes.  Squash plants grow best in full sun and be aware that they are hungry! They will require plenty of fertilizer and drained, rich soil. For truly healthy plants and an abundant harvest, feed the squash fertilizer on a regular basis.

Watering is just as important especially during the growing fruit stage as well as when the weather is dry. If you do not water your squash regularly, it may result in the fruit ripening before it is ready. Do not soak the soil; merely keep it moist as you would any other garden vegetable. You will want to train the vines in the direction you wish them to grow. Trim them regularly and get rid of tertiary vines. This will promote fruit that will grow larger. Carefully handle the vines as you turn them as needed. Squash is not considered a hardy plant. They are susceptible to a number of fungal diseases and bacteria. Some common problems might be bacterial wilt and powdery mildew. If you notice any problems, treat with fungicide immediately.

Good luck.
