|Now that Colorado is finally moving into the hot days of summer, be aware of how warmer temps affect edibles – especially our No. 1 homegrown crop, tomatoes. While we often think tomatoes thrive on warm days, that’s not exactly the case. According to the tomato growers at Jung, it takes about 5 weeks for a tomato flower to become a fully ripe fruit. During the first 3 weeks it grows to full size and during the last 2 weeks, it ripens. Temps soaring above 90 degrees will slow down this process. What happens as temps rise?
Once those really hot days have passed, it may take five more weeks to begin harvesting tomatoes again. Fortunately, successive 100-degree days are rare along Colorado’s Front Range and at higher elevations. Cucumbers Multiple days of excessive heat can cause cucumbers to drop their blossoms or for developing fruit to become deformed and acquire a bitter flavor. When preparing cucumbers, cut off the stem end and peel off the skin as this will remove much of the bitterness. Other edibles
Other heat-related problems
TLC for heat-stressed plants Allowing plants to dry out during a heat wave will stress them further.
The good news about hot, dry weather is that it deters fungal diseases such as powdery mildew on impatiens and edibles as well as Ascochyta blight in lawns – all of which have been a problems in some areas this season as a result of prolonged periods of precipitation.
