I have the white, fluffy fungus on my small tomato seedling soil. I have taken steps to increase the air circulation and decrease the humidity. Can I scrape off the fungus from the very top soil without having to repot the plants, as they are still quite small?
My 1920's garden book lists "Cheshunt Compound" to solve this problem but I have not been able to find either that or an equivalent. I now make my own seeding and potting mixes from sharp river sand, aged sifted horse manure and compost which has a high seaweed content. I also water my seedlings with very weak liquid seaweed manure and have had no fungus problems since starting to use it. I prefer kelp seaweed but use what ever I can collect, put it through my mulcher and soak it in a plastic (not metal) barrel for at least two months and stir it daily. I also feed my mature plants with seaweed mixture and have virtually no disease propblems. Hope this helps.
I'm trying to find a sweet meaty tomato that will hold up to the intense heat of the Arizona summers. Any suggestions? An indeterminate variety would be preferred.
I like Arkansas Traveler Tomato. It is a good heirloom variety that does well in the heat and has a good flavor. When I buy heirloom seeds, I like to shop from either rareseeds.com (Baker Creek Seeds) or seedsavers.com (Seed Saver's Exchange). Both are good companies with a great selection of heirlooms.
Last year I replaced the black landscape fabric in the garden where I plant my tomatoes. The tomatoes seem to do a lot better with the black fabric. Last year we had a really damp and cool spell in the summer and my tomatoes developed some type of blight or wilt; I couldn't determine which it was. I cut all the infected leaves off and removed all the infected tomatoes and sprayed with a fungicide called Daconil. It seemed to help for a while but it came back and the tomatoes didn't do very well at all. My question is whether I can reuse the landscape fabric. I plan on moving my tomatoes to another spot in the garden, but I just bought the new fabric last year and would really like to reuse it.
You can reuse it, but you will need to sterilize it. With landscape fabric, this can be done by soaking it in boiling water a few times or in bleach water (though bleach water will damage the fabric some) to kill the bacteria.
My tomato plant looks healthy. Why are the blossoms falling off?
This is caused by a pollination issue. Mostly, tomatoes are wind pollinated, but in damp/rainy weather or very hot weather the pollen gets sticky and does not travel well. You may need to give it some help. These articles can help:
I am a Family & Consumer Science teacher growing tomatoes, lettuce, basil, beans, and parsley from seeds in an aeroponics unit in my classroom. We are misting the roots with nutrients, but the little tomato plant leaves are turning yellow and the basil bright dark green. I think the nutrients need to be changed-using 5-7-5. Do they need nitrogen? No one could help answer this.
It is a nutrient imbalance. They do need nitrogen to produce foliage, so yes, adding more nitrogen will probably help them do better.
My tomatoes last year were covered in little white flies and now my hibiscus in my greenhouse is covered in them. I can't seem to get rid of them. What do I do? They are also killing my coleus that I am propagating.

How can I control aphids on tomatoes?
I would recommend spraying with neem oil. It is safe for humans, animals and beneficial insects but is very effective on pest insects like aphids. Here is more information:
Have you used baby powder in the soil and/or sprinkled onto the leaves?
