|I have wax begonia's and the leaves are turning brown. I also have hydrangea bushes and the leaves are turning brown. Am I watering them to much?
|Browning leaves can indicate inconsistent soil moisture, salt build-up in the soil from excessive fertilizer or salts in the water, or soggy soils. In the case of the begonia's, browning foliage might also indicate lack of humidity around the plants. If you're watering more than once or twice a week, you may be overwatering. Try deeply soaking the soil around your plants once each week rather than every few days. This will encourage deep root growth which will make your shrubs less susceptible to wilting during hot, dry weather.
