Have you been fertilizing?

Yes... what type of soil did you use in your pots and have you been fertilizing? If so, with what and how often?

Well all the plants are for containers,seeds from thomas& morgan,wintersown or direct.All have been out since before our last frost date of May 30.I planted them in a mix.I got a broken pallet at home depot so did a mix of about 50% mg for container soil /4 months feeded, 25% home grown compost, 25% peat.I have sprinkled corn meal in the soil twice and couple of teaspoons epson salts twice. Three Hail Mary's and several Our Fathers and still no fruit set.

bumped this, hoping for help

Well, let's start with the Miracle-Gro. Most of them are "potting mixes" exactly which did you get?

Now your compost... what materials have you been putting in your compost to create it?

How large are your containers?

How often do you water and by what method?

How much sun exactly? Are they near the house or other structure? Or are they in the middle of an open area to get sun from 6 am until 8:30 pm?

So how old are your plants...have they been around long enough to be bearing lots of fruit...I notice you are 6NY...so what was your plant date?
