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 :).

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.

-- WOW -- I'm not sure HOW MUCH of each amendment (manure, bone meal, blood meal) you put in ... but it sounds like there is enough nutrition there for awhile. I am concerned about 2 things: 1. The initial acidity of the pine mulch. Tomatoes do like slightly acidic soil, but the initial acidity here could be too much. Pine mulch does however break down neutral and pine mulch offers several benefits for gardens, including weed suppression, moisture retention, and improved soil structure. 2. You need to ensure your 5 gallon buckets have a few large holes on the sides near the bottom - this is to prevent your roots from cooking. Even if your containers are in the shade (with the plant in the sun) those containers need aeration. I suggest at least 2 (and up to 6) 3" holes around the bottom sides of your container -- don't worry, after the initial soil spill, the soil will stay put even during watering. As far as continued fertilization, you could top dress with chicken manure -- that is add an inch or two to the top of the soil (top dressing) of chicken manure, and when you water this will go into the soil. Perhaps monthly, maybe more if the plants are growing fast.... I might however hold off for the first couple of months (this really depends on HOW much of each amendment you added -- for example, half a 5 gallon bucket of chicken manure, opposed to several handfuls) -- additionally, when the plants are really small... they don't intake that much nutrition , but as they grow -- they really use up the nutrition fast (think a 5 year old boy compared to a teenager)
