Dear All

I wonder if any of you would be kind enough to help me with the following
problem

I have a cox apple tree which crops well I pick the apples when they are
ripe and wrap them individually and store them in the dry

After about 4 - 6 weeks they become a bit spongy

The ones I buy in the shops now are firm & in perfect condition

Does anyone know what I'm doing wrong ?

Thanks in advance

Sparky
