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 :).

I’m growing tomatoes in a 5 gallon bucket. I have flowers but no fruit. Planted April 19th. Last year same thing lots of flowers but no fruit. What am I doing wrong?

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!

Maybe you don't have enough pollenators. Have flowers around. Make sure you're not spraying something that kills or repels pollinators.

Try a bit of pot ash or potassium.

Can I grow tomatoes all year round and do they reproduce

Read the notes here for cool mountain areas. Plant spring 8-17 until harvest and then pick for a few months ??? Tomatoes left on the ground will self germinate when the soil temperature is right for germination.

I have usually dug in some mulch and let it rot, put a bit of lime on and some fert N- 15.3 - P-4 - K 11.7. I know this is high N and will be using one with about 12 N 3.5 P and 14 K in the future (recommended by fert company that supplies to a lot of commercial growers of veggies around here). From the above I generally have very strong looking plants - I will say I realise I should cut back on the N and will be in the future. I have just started to make some compost the last few months. On a replanting now, I'm putting on about 3 x 20 liter buckets of compost/mulch per sq meter and adding lime and some fert. Will see how that goes - still probably too much N. I'm also adding some trace elements and Epsom salts to my soil. It should be good soil lol
