The first basket is freshly trimmed. I took it out of the greenhouse and hung it about mid May.
I added 4 Tablespoons of slow release from Proven Winner fertilizer.
The 2nd. basket is full grown in August. I never took them down because of the wind! they just got too big.
I have my baskets on a timed drip system. It comes on everyday for 1 hour. It does a better job than hand watering, because the Pro Mix potting soil (in the basket) can better absorb the water at a slower rate than hand watering.
I add "Daniels" -name changed to "Nature's Source" - to every watering. I use 1 Tablespoon to 1 gallon of water.
I have even used 2-3 Tablespoons to 1 gallon of water. You will never burn your plants using "Nature's Source".
If you feel you don't have enough flowers on your basket, it could be because you are starving your containers.
