Strawberries
Strawberries should be fertilized with a pound of nitrogen per 1000 square feet
in early July. If fertilizer is broadcast, drag foliage with a sack to dislodge
fertilizer from plant foliage and water thoroughly. Repeat this process in September.
Applying nitrogen fertilizer immediately before fruiting causes soft fruit and
is not a recommended practice. Strawberry plants should continue to bear fruit
for approximately three years.
Vegetables
Vegetable gardens need regular irrigation to keep plants moist throughout the
growing season. This is especially necessary when the edible portion of the
plant is developing. The addition of mulch helps to conserve water and maintain
even soil moisture.
Powdery Mildew
Powdery mildew is a leaf fungus that affects many plants. The fungus produces
symptoms that include spots or patches of white to grayish, talcum powder-like
growth on leaves of susceptible plants. Those most prone to powdery mildew in
Colorado include roses, zinnias, columbine, summer phlox, lilac, grape, apple,
cherry and others. Good cultural practices are the best defense, such as planting
a less susceptible species. Pick a sight with plenty of sunshine and air circulation
to allow foliage to dry quickly after watering or rain. If needed, use a systemic
fungicide to protect new growth.
