New Year, New Garden! January Gardening Tips

Happy New Year from the statewide UC Master Gardener Program. Gardening in January can be a challenge with the cold weather and shorter days. However, January can be an excellent month for garden maintenance and preparing your landscape for spring and summer.

From giving your garden a makeover to planning for a vegetable garden, there are endless opportunities to stay active in the garden in January. What steps can you take to improve your garden this month? Here are a few tips to get you started:

1. Watch weather reports. Accordingly, protect your plants from frost and other weather conditions. Cover them when necessary and adjust watering both for cooler temperatures and for seasonal rains.
   
   
2. Don't forget about your houseplants. Make sure to keep your houseplants watered, as they tend to dry out from indoor heating during the winter months.
   
   
3. Clear dead plants and debris. Give your garden a clean look for the New Year and allow more space for new growth. Don't forget to pull out weeds.
   
   
4. Keep your garden tools sharp and clean. Avoid rust and dullness and prepare for the pruning that takes place in January and February.
   
   
5. Prune dead or damaged branches. Since January is the dormant season, it is the ideal time to prune. Prune your fruit trees while avoiding apricot and cherry trees. For more instructions on how to prune, check out this pruning guide.
   
   
6. Start your vegetable garden indoors. Expand your growing season and start seeds, you can plant cabbage, chard, broccoli, cauliflower, and spring lettuce, to name a few. You can also start them in a cold frame or greenhouse.
   
   
7. Plant flower bulbs. Get a jump start on planting flower bulbs this month, which can lead to a longer spring bloom!
   
   
8. Plan your spring and summer vegetable garden. Design a garden plan now to prepare for spring planting. A great first step is to draw a map of your garden on grid paper and consider which seeds you want to plant and where.

January is a time of new beginnings, including in your garden. By preparing now, you can expect fantastic results in the spring and summer months.

5 Common Tomato Problems and Solutions

One of the most versatile and rewarding plants in a summer edible garden is the tomato. According to a 2014 study by the National Gardening Association, 86 percent of homes with vegetable gardens grow tomatoes. It is understandable that the tomato plant is a popular home vegetable garden staple, tomatoes offer thousands of different varieties options and flavors. Plus, nothing beats the flavor of a ripe tomato straight from the garden.

When properly cared for, a single tomato plant can produce 10 to 15 pounds (4.5 to 6.8 kg) or more of fruit. If tomato yields aren't what was expected or the fruit is damaged it could be due to a number of abiotic disorders, diseases or pests. Abiotic disorders result from nonliving causes and are oftentimes environmental, for example: unfavorable soil conditions, too much or too little water, temperature extremes, physical or chemical injuries, and other issues that can harm or kill a plant. Below are five common abiotic disorders of tomatoes and recommended remedies from the UC Agriculture and Natural Resources publication, Growing Tomatoes in the Home Garden. 

1. Sunburn

Problem: Fruit turns light brown and leathery on side exposed to sun.

Cause: Overexposure to sunlight.

Solutions:
• Maintain plant vigor to produce adequate leaf cover.
• Avoid overpruning.
• Provide partial shade during hours of most intense sunlight.

2. Leaf Roll

Problem: Older leaves roll upward and inward suddenly, leaves become stiff to the touch, brittle, and leathery.

Causes: High light intensity and high soil moisture, particularly when plants are staked and heavily pruned

Solution:
• Choose less-susceptible varieties.
• Maintain even soil moisture.
• Provide shade during hours of intense sunlight.  

3. Blossom End Rot

Problem: Water-soaked spot on blossom end of fruit enlarges and darkens, becomes sunken and leathery. Affects both green and ripe fruit, and is more common on sandier soils.

Causes: Calcium nutrition and water balance in the plant, aggravated by high soil salt content and fluctuating soil moisture.

Solutions:
• Maintain even soil moisture.
• Amend planting area with compost to improve water retention.
• Avoid heavy applications of high-nitrogen fertilizer.
• Soils deficient in calcium may be amended with gypsum. 

4. Fruit Cracks and Catfacing

Problem: Circular concentric cracks around the stem end (concentric cracking), cracks radiating outward from the stem (radial cracking), malformation and cracking at the blossom end (catfacing). 

Causes: Very fast growth with high temperatures and high soil moisture levels. Wide fluctuation in soil moisture and or air temperature. Any disturbances to flower parts during blossoming.

Solution:
• Keep soil evenly moist.
• Maintain good leaf cover or provide partial shade during hours of most intense sunlight.
• Mulch around the plant 3 to 7 inches deep to maintain soil moisture and temperature.

5. Solar Yellowing and Green Shoulders

Problem: Yellow or yellow-orange instead of normal red color, upper portions of the fruit remian green even though the lower portion appears red and ripe. 

Cause: High temperatures and high light intensity.

Solutions:
• Maintian plant vigor to produce adequate leaf cover.
• Avoid overpruning.
• Provide partial shade during hours of most intense sunlight.
