The Q&A Archives: Black Eyed Susan Hanging Baskets Witherine

Question: I have 2 hanging baskets of black eyed susans - they are in an extremely hot area - direct morning sun until around 2pm or later - they were beautiful when I put them up but 2 days later were withered - I am trying to water them at least every second day with about 3 or 4 cups of water - is this too much? or not enough? Can they take extreme heat (it was 110 the other day in that corner)? Please help as I don't want to lose them - they were really lovely.

Answer: This vine is heat and sun tolerant, but 110 is extreme. Direct sun until 2:00 should be okay as long as it is well watered and it is not up against a wall reflecting heat onto it. It will do best if the soil is kept evenly moist but well drained, meaning damp like a wrung out sponge, all the time. It should not be sopping wet/saturated or dried out. Use your finger to dig into the soil and see if you need to water; in hot weather and if the plant is proportionately large for the container you may need to water twice a day. When you water, make sure the water is soaking into the soil and not running out between the soil and the side of the pot. If the soil has dried out, soak the pot in a bucket of water to re-wet it. Also, the hanging basket container must have drainage holes in the bottom to let excess water run out.
