Problems that affect a Butterfly Pea Plant in Summer

A butterfly pea plant is fairly drought tolerant. It can survive well on hot summer days. The summer season is usually the best time for these flowering vines. Although if the temperature scales above 38 degrees celsius then it may cause several problems. The mortality rate of the Butterfly pea plant is fairly low even at 40 degrees celsius unless you forget to keep it well hydrated.

The Common problems that can affect a butterfly pea plant in summer include-

  • Acute Dehydration,
  • Leaf and flower drop,
  • Reduction in flower size,
  • Color fading of flowers, 
  • Foliage and vine tip Burn
  • Partial death and dryness of long Butterfly pea vines.

All of these problems are directly related to the lack of moisture. Acute dehydration occurs when the plant does not get water for 3 to 4 days at a temperature above 32 degrees celsius. This condition will result in curling and drooping of leaves. Latter the leaves at the farthest distance will start falling off the vines. Then the vine tips will start drying and if the plant is not hydrated by this time then it may die eventually.

Even if the plant is safe, it will slow down new bud formation with subsequent temperature rises. The butterfly pea plant will try to save as much moisture as it can to stay alive. It will result in small flowers with faded coloring. If a temperature above 35 degrees celsius is common in your locality during summer. Then you should grow these vines in part shade where the chance of overheating and excessive evaporation is low.

Apart from high burning temperature, pests and diseases can also cause problems to the butterfly pea during summer.
