My beans are going yellow!

| Hi there, just a quick question regarding my dwarf green beans. I planted them as seedlings two weeks ago(they were bought in the punnet) but they appear to have turned a little yellow. Two of them have dark brown streaks on the stems but all the plants seem more yellow than green. Should I worry about this? This is my first attempt at a veggie patch so I'm still learning. They also have small black flying insects on them - I assume they are aphids?
Cheers,
Lyn |

Not familiar with that. Yellowing can be caused by something as simple as overwatering or perhaps a missing nutrient, like Nitrogen. If it's too much water, just ease back. I'd apply a good organic fertiliser (I like combining fish emulsion with seaweed extract) along with some Sulphate of Potash sprinkled around the plants, whatever the problem.
If you suspect that the brown markings represent disease, remove the offending plants and burn them.
Hope this helps. |

| Don't know where in NSW you are, but beans aren't fond of cold soil. Regardless, they do love a bit of potash. Try about a matchboxful for each plant before watering and scratch it in gently without disturbing the roots. |

| I'm on the mid north coast (Coffs area) so I don't think cold soil is the prob as it's been quite warm since I've planted the seedlings. Could be overwatering tho'! How often should I water my veggies??? I've been doing it daily. It has a good cover of mulch so maybe I have been over watering. I have lettuce near the beans so have been trying to keep the water up to these. Thanks for your tips. Cheers, Lyn |

Let the veggies determine their water needs. Wilting during the day is quite normal and is okay. They should recover fairly quickly when the sun goes off them, especially since they're mulched. If they're still wilting next morning, they need water. The only exception I'd make is lettuce. If the water's not kept up to them, they can get bitter.
Hope this helps. |

| Yep. Daily sounds like too much, 'specially with mulch. You can always poke a finger down through the mulch to find out what's happening down there. |
