Vege garden help

last modified: November 21, 2018

Hi all,

I'm new here and new(ish) to vegetable gardening. I have a small area at my flat where I have some large planter pots that I am trying to grow vegetables in.

However, the lettuce seems wilted and slightly pale leaves (almost a yellow hint to them). The tomatoes seem better but still don't seem to be flourishing. I have used a premium potting mix, and for the tomato pots I bought tomato potting mix.

I have used an all round liquid fertilizer also. They receive good amount of sun a,d watering.

Can anyone help please?

    I guess I have to wonder if the fertilizer is being applied regularly, and according to instructions for containers. Can you be specific about the fertilizer? Is the soil moist a half-finger down? The soil surface looks dry, so I suspect you aren't overwatering.

    The fertiliser is 'Yates Thrive: Tomato & Vege Natural' I applied it as per instruction.

    I've watered on dry days but we have had some rain which too. The soil is moist to half finger down at least.

    That fertilizer looks to be solid. Well, yellowing leaves often point to some rather unhelpful diagnoses. As in, too much or too little water, too much or too little light, and too much or too little nutrients. There are diseases that can come into play, but I suspect we're dealing with the too much or too little here. Coin flip time.

    How many hours of full sun do they get?

    Full sun approx 6 hours.

    How would I determine if they are being over watered? I guess there is a possibility of the pots not draining properly

    That's plenty of sun. If the soil surface is dry, they're not obviously being overwatered. But yes, if the pots are not draining properly, that could make for big problems down below. I guess the question becomes whether the soil turns to mud deep down. A good potting mix shouldn't pack up and hold water in, so you might ask yourself if the holes in the pots are clogged.

    "The soil is moist to half finger down at least."

    Then there is no need to water. If you stick a finger in and feel that it is moist then there is still plenty of water for the plants to take up. If you are watering even when you feel moisture then you are almost certainly overwatering. The dryness of the soil surface has nothing to do with how much moisture is actually in the soil. The surface can be dry while underneath is still plenty moist.

    What are your temperatures down there in New Zealand?

    Currently between 10c and 18c

    10c is a bit chilly for a cucumber.

    The lettuce actually look OK to me. The centre leaves are crisp and they're the ones that show you if the plant has transplanted well. How long ago did you plant them?

  • daninthedirt (USDA 8a, HZ10, Cent TX, Sunset z30)

    I think the OP said lettuce and tomatoes. But yes, tomatoes will not thrive at those temperatures. They'll live fine, and grow, but they will do so slowly. The lettuce does look pretty yellowish. Did you check the pot drainage?

  • floral_uk z.8/9 SW UK

    The OP did say tomato. But the second picture shows a sad little cucumber. It’s even labelled as such. That’s why I mentioned it.

  • daninthedirt (USDA 8a, HZ10, Cent TX, Sunset z30)

    Good point, but I see no labels. I don't see a lot these days, thanks to Houzz. They're looking into why.

  • floral_uk z.8/9 SW UK

    The label’s at the side of the pot half out of the picture. I’m using an iPad and it gives eexcellent magnification. Better than my pc.

  • daninthedirt (USDA 8a, HZ10, Cent TX, Sunset z30)

    That's interesting. On my Mac with Firefox, I only see a piece of the picture. That label is in barely it, but almost illegible. If I click on the picture, I can see more of the picture, with better magnification. That's a pretty small label, though. Good eyesight!
