PLANT GROWTH ACTIVATOR (PGA) PROTOCOL
At time of planting the PGA was prepared as follows: one (1) tablespoon of PGA was diluted in one (1) gallon of water. It was applied as a root drench to six (6) Hypoestes(6) Coreopsis and (6) Caladium bulbs. Each plant / bulb received 1 quart of finished solution. After soaking the plants / bulbs the hole was backfilled. The plants / bulbs that received the PGA root drench were treated monthly with PGA throughout the trials. The monthly maintenance dose was again 1 tablespoon in 1 gallon of water. Once again each plant received 1 quart of finished solution. A control was set up consisting of (6) Hypoestes (6) Coreopsis and (6) Caladium. The control received only water at time of planting and was not treated at all with PGA throughout the entire trial. All the plants / bulbs in the experiment (treated & control) were fertilized at label rates monthly with an organic fertilizer with an analysis of 4 - 1 - 1. All plants / bulbs (treated & control) were watered on an as needed basis and were observed daily during the first week and then weekly thereafter. The trial ran for 12 weeks.
WEEK1
HYPOESTES: 2 of the non-treated / control plants showed signs of planting shock immediately
following planting. The foliage was wilted, limp and somewhat curled. One of the plants
recovered and one died at the end of the first week.
COREOPSIS: One of the non-treated / control plants showed signs of planting shock on day 2
and died within 5 days.
CALADIUMS: No visible difference
WEEK 2
HYPOESTES: 4 of the 6 treated plants showed new growth while non-treated / control plants did
not. The plant that initially showed signs of planting shock and recovered again looked wilted and
limp.
COREOPSIS: No visible difference
CALADIUM: No visible difference
WEEK 3
HYPOESTES: All 6 of the treated plants showed new growth, while 2 of 6 non-treated / control
plants showed new growth.
COREOPSIS: 3 of the 6 treated plants showed new growth while 1 of 6 non-treated / control
plants showed signs of new growth.
CALADIUM: 4 of the 6 treated bulbs had pushed 1 - 1 ½ inches above the soil line while non
treated / control bulbs showed no signs of above ground growth.
WEEK 4
HYPOESTES: All 6 of the treated plants were 10 - 15 % larger than the non-treated control
plants. By this time 4 of the 6 non-treated control plants showed new growth.
COREOPSIS: All 6 of the treated plants showed new growth while 3 of 6 non-treated / control
plants showed new growth. 3 of 6 treated plants started to bud up while none of the non treated /
control plants showed signs of budding up.
CALADIUMS: All 6 of the treated bulbs were now showing growth above the soil line averaging
2 ½-3 inches. 3 of 6 non treated / control plants were showing above ground growth.
