Pumpkins are going in this week, but I'll make sure I'm in the right frame of mind. Check out this advice I found on the web!
The most common form of bonding with your pumpkin is simply to talk to it. It responds quite well to positive re-enforcement. It also responds negatively to criticism and negative re-enforcement. Don't ever threaten your pumpkin or mention your doubts and disappointments within hearing range of the plant. The mere mention of your disappointment of it's growth rate can cause the growth to completely stop for a period of time. Fortunately, pumpkin plants have extremely poor hearing, about ten feet.
A second form of bonding is singing to your plants. This is slightly more effective than talking in an encouraging manner to your crop. It also can backfire as the choice of music is vital. Those who can not sing can turn off the pumpkin, stunting all growth. Sad songs and slow elevator music can also result in reduced production. Slow music can put your pumpkin to sleep.... normally pumpkin fruit grows 24 hours a day. An upbeat, fast tempo is the preferred choice. However, marches are to be avoided as they may cause the pumpkin to grow too quickly and literally burst. Most importantly, do not forget to sing love songs during the pollination period, especially during early morning hours when pollination peaks.
