They probably need a heavy pruning to rejuvenate them. I would give all of the some water that has both a product called Super Thrive and root stimulator in the same water. Water them with a fresh batch of this mix the next 4 to 5 times they need watering. I would also give them all 1/3 cup kelp meal, scratch it into the soils and water in. You can use the same water mix noted above to water in the kelp meal.
