Often annuals, such as pansies, suffer in the heat of the summer. When temperatures soar and rain comes less often, pansies will be stressed and will start to fade. Gardeners can lessen this stress by protecting pansies from heat and drought as much as possible. Revive your pansies after the drought by cutting them back slightly, fertilizing and coaxing them into renewed growth.
Use the pruning shears to cut back the pansies by approximately half. Although this pruning seems severe, pansies will respond by putting forth new growth from the remaining stems. The new growth will include lush lateral growth, new buds and new flowers. In one or two weeks after pruning, the pansies will appear much healthier.
Fertilize the pansies by mixing the fertilizer with water according to package recommendations for the size of the growing area. Carefully pour the fertilizer around the base of the pansies and avoid splashing fertilizer onto the foliage. Fertilize the pansies approximately twice a month to return them to health.
Provide regular water to the pansies as you are trying to revive them and to help them recover from the pruning. Water the pansies when the soil dries slightly. Never allow the pansies to dry to the point of wilting.
Expect the pansies to begin to blossom again after nurturing them. After each blossom fades, deadhead the pansies by clipping the spent blossoms from the plants. This will encourage the pansies to continue to blossom.
