It depends on your purpose for the tree..

As we know, the more you pick off the fruit the more energy goes into making roots and growth..

If you are growing it for fruiting purposes, why not reap the benefits while you can until it's fruits are gone as long as you keep your tree actively happy?

I know many that leave their tree full of fruit for prettiness sake and making jelly all winter in which their trees do perfectly fine...

Growing outside or in lot's of sunlight should have built up energies reserves to sustain your tree throughout the whole winter despite being laden with fruit..

If you have no need for the fruit, then you could do as I do and take them all off now.

Welcome to this forum and enjoy your day:-)
Pics always welcomed..
