tomato plants getting way too tall
So I did not plan well at all, this is my second year at growing tomatoes, last year was a disaster so I had no success. This year all my heirlooms are reaching for the sun, I planted them in late march and they are setting fruit like crazy and starting to ripen.
My problem is they are over 7 feet tall, out grown the junky 54inch cages and the limbs are breaking off and cages are wanting to topple over. I have secured the cages to a near by fence so they wont fall over. I am tying the limbs up to the fence to hold them up straight but they are taller than the fence now.
from what i am aware i have a really long season and almost no frost where im at till december.
what should i do?
Should i top them?
Is it normal to grow to 7ft in 3 months time?
