A Little Extra Work Goes a Long Way
Mulching around tomatoes is perhaps the most overlooked (and important) part of growing quality tomato plants. Mulching with (herbicide-free) grass clippings, straw, or fabric will not only keep the weeds out, but also prevent blight. Tomato Blights live in the soil and hurt the plants when that soil bounces up and hits the bottom leaves. Mulching around the stalk and out a few feet will help to prevent blight from ruining your crop.
What's wrong with my tomatoes?
By no means is this a complete list of tomato problems, but knowing a little information about tomatoes now can prevent a lot of google searches for "black spots on tomatoes" later.
If you notice your bottom leaves turning yellow and brown with spots of black there's a good chance you've already been infected with a blight. To be sure, bring a sample to our Lawn and Garden employees for an identification. Pick infected leaves off and spray the rest of the plant with a copper fungicide to prevent the blight from spreading (wash hands and tools before touching another plant). Always water at the base of the plant and never from above. Proper watering will ensure happy, blight-free tomatoes.
Blossom End Rot
You've spent your summer mulching, watering, and fertilizing, the time is finally here. You've worked hard for this moment. Cherish it. You pick your perfect tomatoes and that's the moment the anger sets in. The bottom of your tomatoes are black... You gave them enough sun. You mulched. You watered from the bottom. You did everything right. Well, sort of. Fertilizing tomatoes correctly is another important step. Blossom End Rot is caused by a calcium deficiency. To prevent Blossom End Rot, use a fertilizer with a good amount of calcium. We recommend Tomato Maker.
Well, it looks like you're not the only one who thinks tomatoes are delicious. Bugs like tomatoes too. There are some easy and safe fixes. For spraying the insects we like a product called Captain Jack's Deadbug by Bonide. It's natural, and best of all, it works. They eat the aphids and not the plants.
