I’m planting Plum Lemon Tomatoes. Do I start in trays or sow directly into the container?

We have planted two different tomato transplants in our raised bed. Bed is about 18" deep. Have good soil, topped with compost, then covered with straw. How often should we be watering this time of year? Current daily temps are around 70-75.

If it is hot a good watering 3 times a week - not so hot 2 times a week. Small plants need small waterings more often. The finger test is a good indicator also.

nick, I've read just to stick your finger in about 2 in. and if it's dry, then water. There's also fertilizing to consider. Homestead and Chill is a great website that has articles on Tomato's (deep watering/ shade cloth) and alot more. dan

I started my seeds back in January and transplanted them out mid-march like the diagram said. However, it does show you can plant them in April, but I would be careful because just as they are starting to take off the heat and humidity will be setting in. Depending on the variety most plants will not produce fruit when temperatures are consistently about 90 degrees. Which we are almost there in our zone. Adding shade over them can help! Otherwise, I use the tapping method to aid with pollination :).

Do you see any pollinators? Try using a tiny paint brush to mix pollen on each flower.

Just lightly tap the flowers in order to pollinate them and they will form tomatoes.

Try watering with a mixture of epsom salt (1 Tbsp per gal of water). Also, if you,ve seen the banana peel water combination I swear by these two methods. I have the biggest plants and the tomatoes are just loaded on every single plant. It works great for peppers too!

I have been growing tomatoes in pots at North Sydney for the last 10 years. Each year is more problematic and depressing than the previous even though I sterilise pots and use new potting mix each year. Plants start off very healthy then about the time that fruit set, the plants start yellowing from the bottom and within a few weeks they are history. This year was interesting in that I placed the pots on a second story balcony well away from previous plantings on the assumption that whatever was killing the plants near the ground may not exist on the balcony. I planted in September, great plants until mid November when they did the same thing - started yellowing from the bottom up and ended up basically dead after a few weeks. I took one of the plants (Mighty Red) which was dead except for one small leaf about 10mm above ground level. I cut the plant off completely immediately above this leaf and planted it in a new garden bed we have recently created in the area where we had previously used pots. For a couple of weeks nothing happened then the plant started growing and now in mid March we have just picked 3 large tomatoes off a very healthy (large) plant with another 15 or so tomatoes still on the plant. I still don't know what causes the problem but the experiment with this 'Lazarus' plant is nothing if not interesting.
