tub potatoes
I planted potatoes in large tubs last year, and my biggest problem was
watering(over or under). What is the best way to know when and how much
water to use ? Do I need drainage holes up the sides of the tubs ? Can I get
a device to measure water content ? Should I use water retaining gel or
crystals ? and as I will be growing in compost what fertiliser will give the
best results? Sorry there are so many questions but I am a keen beginner.
