I forgot to take a picture before I trimmed a lot of the brown dead leaves, but hopefully someone can still see the problem. It's been very hot these last couple weeks so I started watering twice a day. The peppers are doing great, but cucumbers and tomatoes are dying. Any thoughts??

Hello! How long should I wait to water after spraying NEEM oil in my garden? Thank you!
Avoid overhead watering in most cases, then it will not effect the Neem Oil application.
Dear Sir/Madam I have a number of indoor plants in pots, and always worry about when to water. I have seen moisture meters online ranging in price from £5 up to over £100. I would just like to pop into my local garden centre and get the cheaper probe type that just pushes into the soil and a meter on top gives a reading. But can they be any good at the price? The Plants I am particularly worried about are Ficus Elastica, Ficus Benjamina, and Amazonica Alocasia Thank you for your help Stewart Hawkins

Hi! Is it ok to water potted plants without an attachment? I'm just pointing the stream of water at the inside of the pot so it doesn't hit the soil directly. Or is it ok to just hit the soil directly with the water stream? Thanks!
It's better to have an attachment, but if you don't, then any kind of water is better than none! The main reason you don't want the water to hit the soil directly is erosion - if you water with a single stream in the same spot, it'll wear away the soil and expose the roots, which is bad. If you put the mouth of the hose against the soil, though, or point it against the side of the pot as you suggest, you should be okay. Just watch the soil and see what happens.
My husband thinks it is useless to water unless the sun is out because photosynthesis is not occurring. I say you can also water on overcast days, especially during our dry periods. He says there is no benefit on overcast days. (Rain is not forecast, it's just cloudy. We are in a drought.)
You will be glad to learn that photosynthesis will occur at anytime there is any visible light present. This includes overcast weather. Also worth noting, is that watering and photosynthesis aren't necessarily connected as you would think. They can use water without photo synthesis, as they are still breathing all the time. This "breathing" is where most of the water is being spent, along with some being used for the photosynthesis cycle. It is best to water in the early morning, if possible.
Should I use Distilled or Purified water on tropical plants? Thanks Lloyd Stone
Most of the time, regular tap water will be just fine. If you have a water softener, then this can pose a problem. You can use purified, or distilled water, but I can't tell you how many times I have seen a CHLORINE deficiency in plants by doing this. (Yes they use small amounts of chlorine) But if you use a balanced full fertilizer, then this should not be an issue.
I am doing a science experiment and I want to know how much soft drink should I put in the plant so there is an effect on the growth?
This article may help you with your experiment.
