Preparing Your Soil for Planting Garlic

Why are my tomato blossoms drying up and dropping?
Now that your tomatoes are bursting with growth and flowers and you are waiting for the fruit to ripen, you find flowers dropping or withering on the plant. Why is that happening? The problem is called blossom drop. The main reason is that the flowers are not getting pollinated. Tomatoes have perfect flowers, meaning both male and female flower parts are in the same flower. The pollen is moved from the male part (stamen) to the female part (pistil) by wind movement of the plant or by vibration of the flower by bumble bees or other pollinators.
So what are the causes of lack of pollination?
One of the main causes is from daytime temperatures exceeding 85°F or nighttime temps rising above 70°F or dropping below 55°F. You can put up some shade cloth (30% should be enough) over your tomatoes, positioned so it is shading your plants during the hottest time of the day. To learn more about other causes of flower drop, you can read the blog Why are My Tomato Flowers Falling Off and Not Making Fruit?

Preventing Blossom End Rot on Your Tomatoes and...
Tip of the Week: Blossom Rot
If you see black or rotting bottoms on your tomatoes, peppers or eggplants (less common), it is most likely blossom end rot. Tomato varieties that set all of its fruit at once (determinate) are commonly affected; cherry tomatoes rarely get blossom end rot. It is caused by a calcium deficiency in your plants caused by soil deficiencies or from uneven watering (calcium is not taken up).
To help prevent this, mulch around your plants to help conserve soil moisture, keep your plants evenly watered, and make sure your soil has sufficient amounts of calcium. If your soil has sufficient calcium, then no supplement is needed. Don’t over fertilize your plants with high nitrogen either. Excessive nitrogen will lead to more foliage which will reduce the amount of calcium available to the fruit. Remove the damaged fruit.

Is it Time to Harvest Your Garlic?
After your garlic has produced scapes (hardneck varieties) your bulbs are really starting to size up. Once your garlic has a couple of dead bottom leaves you will want to stop watering. You can dig your garlic in a couple of weeks. If you are unsure if your hardneck garlic is ready to harvest, look for about 3-4 dried leaves at the bottom of the plant. Dig up a test bulb to see how well the bulb has sized up. If it is nice and large, you can dig up the remaining bulbs. Don’t harvest too soon or you may have small bulbs, too late and the wrappers may have broken down and your garlic may not keep as long. If this happens eat those bulbs first. Softneck garlic is a little different than hardnecks. Softnecks are ready for harvesting when the top of the plant falls over, similar to onions.
Once your garlic is ready to harvest, dig the bulbs up carefully with a garden fork or shovel. Remove most of the soil, being careful not to hit the bulb (it bruises easily), leaving the roots & stems. Tie the garlic with twine in bunches of 6 to 12 plants. Hang the bunches in a place out of direct sun and rain. Temperatures should be around 80°F and garlic should be cured for at least two weeks. Once cured, trim off the leaves (don’t cut too close to the top of the bulb) and roots, leaving about 1/2” of roots. Store in mesh bags at around 60-65°F in an area with some air circulation.

Pruning out Suckers on Your Tomato Plants
Now that your tomatoes are growing like weeds it is time to prune out the suckers. The advantages to pruning out the suckers on your tomatoes are increased fruit size, better air circulation, which will help with disease prevention and earlier fruit development. The suckers are the stems growing out of the leaf crotch. You should remove the suckers from the bottom of the plant up to the first flower cluster. Remove them before they get too big, less than 2-3” long is a good rule of thumb. You will need to keep an eye on your tomato plants throughout the season and prune the suckers as they get big enough, look for new growth coming up at the ground too and cut those out. Also you want to remove the yellow or dead leaves (especially seen on the bottom of the plant). Only prune the indeterminate varieties; determinate varieties should not get pruned, you can leave the suckers on those plants.
If you are supporting the plants with an overhead trellis with string or wire supported at the top you can allow your plants to develop two leaders or more commonly, it is pruned to a single leader. Prune out suckers along the plant to allow for better air circulation and less weight. You will have a reduced yield, however, the tomatoes that are left will develop earlier and will be bigger.

Additions can be made to your tea–liquid kelp or maxicrop (a kelp extract), or liquid fish are great to supplements your compost tea. You can customize your brew according to the stage of growth your plants are in (growing, blooming or fruiting). The additions can be added at the end of the brewing process. You can apply the tea using a watering can or sprayer (clean).If foliar feeding, dilute the tea to one part tea to 10 parts water (dechlorinated water). Or if applying to the soil, dilute one part tea to 5 parts water (dechlorinated water).
