So much rain…this can cause problems


This rain is just ridiculous.  Tomato plants like to be dry and  warm and they are not getting any of either for a while it seems.  This causes several problems, but you can help solve them a little and keep your plants healthy until the weather warms up and dries up.

Fungal problems like blight, septoria, and fusarium can kill plants quickly especially if the plants are fairly small.  you should prune any leaves that look like they are yellowing, spotted or turning brown.  This can help to keep things from spreading up the plant.  You will likely need to start some kind of fungicide schedule as well.  Spray your plants as soon as the rain stops and then re-apply after more rains.

Options for spraying run the gamut from organic to nuclear.  Liquid copper is the most commonly used organic spray.  Daconil is not organic, but is pretty mild and works well.  Mancozeb is a zinc based fungicide that works very well.  Make sure you follow the mixing and application directions for whatever product you decide to use.  Diligent spraying and pruning are essential to maintain plant health in this weather.

These heavy rains will likely wash a lot of nutrients out of your soil.  Hopefully you fertilized when you planted and that should help matters.  I would recommend fertilizing again very soon due to the heavy rains…especially if your are in containers.  Tomatotone is a great product and is organic, but a good 13-13-13 wouldn’t be a bad idea to replace what the rains have washed away.

Lets hope things dry out and warm up soon!

    My tomato plants are about 8” tall and still in solo cups. I brought them inside to be under the grow lights during the deluge the past week. There’s still a TON of rain in the forecast…boo. Should I leave them under the grow lights until there is a longer duration of no rain in the forecast (which at this point, doesn’t look like it’ll happen until after June)? Should I leave them in their cups and keep them outside until drier days? Or, should I just plant them today (5/22) or tomorrow (5/23) since it’s not supposed to rain till Friday? I know May is *supposed* to be the best time to get them in the ground, but my goodness, this May is wacky!! Any suggestions are helpful and welcomed! Thanks in advance!

      Please get them outside for sure…under grow lights isn’t the best place for them as they need wind to stay sturdy. Best thing to do would be to get them in the soil as soon as it is dry enough to plant. If they don’t develop a root system and get big enough before then heat of summer they will have tough time producing fruit this year.
