A few things I noticed in your pics. One is shading, does the area receieve periods of shading during the day due to trees etc? Tomatoes need full sun-preferably all day.It can make a very big difference. Also the black mulch works well with peppers
- but many dont suggest it for tomatoes. I also noticed a sprinkler in the corner of one pic. Is that the only way you water the garden? Tomatoes do not like to be spray watered (I know the rain but....)as it makes it prone to disease, especially blights, and fungus. Try to water right around the roots with a watering can jug etc. Also is your soil on heavy side? If so next time try growing
in furrows, which are raised rows. This will keep the roots from drowning in water, and the heavier soil will retain water enough to sustain proper growth, it also give more area for the roots to grow in.I cover my rows for tomatoes with grass clippings before I plant, as mulch and nutrients. When you go to plant, pluck off the non true leaves from your seedlings
, and plant them up to the first true leaves, in the furrow. Set up your supports before you plant- I like to grow on a trellis type fencing. Planting them that deep, will cause the whole stem thats in the ground to root, and makes a much better tomato plants. I planted my tomatoes Memorial weekend, and the large cherrys are already above chest hieght! I like to feed using a higher nitrogen fertilzer (standard miracle grow) to get the growth going, then switch to a high phosphate to increase blooms, and fruiting.Dont use too much nitrogen, for too long as it will make more green growth and little fruit. This works well for your peppers
too! (as does furrows) Here is a pic of my tomatoes, It kinda hard to get them in the pic to get an idea of the size, as they are row planted.
