Tomatoes, 2010

In just a few weeks it will be time to plant tomatoes. When you buy transplants, choose plants that have a nice green color on the lower leaves. Choose plants with a thick stem. Avoid plants that have blossoms or small fruit unless they were grown in a 6” pot or larger. If you have not added calcium lime for a few years, apply it when you till your soil. Lime will help prevent the tomato fruit from getting blossom end rot. When you transplant tomatoes into the garden, plant them deep. Tomatoes will develop roots from the parts of the stem that are underground. Apply fertilizer soon after planting.

We are concerned about late blight being a problem in tomatoes again this summer. The summer weather will determine if late blight will be a problem in 2010 or not. It has been a problem for growers in Florida again this winter. If we have a cool wet summer, expect late blight to be active. Late blight does not do well when the weather is hot and dry. Fungicides containing chlorothalonil are effective at protecting tomatoes. If you use a fungicide, it will have to be on the foliage before the blight attacks and thorough leaf coverage is critical.

Also, every Saturday, through May 22nd, we are offering a Spring into Gardening Workshop at Bill’s Ace Hardware, Route 435 Daleville, PA. The Master Gardeners will answer your gardening questions from 11 am – 2 pm. Plus, at noon we will have demonstrations on various seasonal topics. This program is free and open to the public. Here are the upcoming topics:

• May 1st - lawn care basics
• May 8th - landscaping for the birds

Moss

All that grows green isn’t always something homeowners want in their lawn. Dandelions, white clover, ground ivy, perennial weeds, and all sorts of annual grasses are plants needing turf management. One of the first weeds to green-up in the spring is moss.

Many different species of moss can grow and persist in home lawns. Unlike seed-bearing plants, mosses produce spores that can be wind-blown from one area to another. Moss is an opportunistic plant that will develop and grow in bare soil areas or where lawns are weak and thin. Moss does not “crowd out” grass, but once it is established, grass plants will not spread into those areas.

Moss is very persistent and difficult to remove from a lawn unless an effort is made to promote a healthy, dense, actively-growing turf to take its place. Moss in lawns is usually the result of conditions that are not conducive to good growth of turf. It is most commonly associated with shallow, rocky soils; poor soil fertility; low soil pH (acid soils); heavy shade; and excessive moisture. If any of these factors are limiting turf growth, moss can invade the lawn and establish a permanent residence.

The first step in a moss control program is to test the soil for nutrient content and pH. Soil test kits are available from the Penn State Cooperative Extension office for a nominal fee. If the soil is deficient in nutrients or in need of liming, the soil test report will indicate how much fertilizer and lime to apply and when to apply them.

If shade and/or moisture are the limiting factors for good turf growth, steps should be taken to correct the situation or plant grasses that are adapted to shaded or moist areas. The fine fescues are the best-adapted turfgrasses to shaded, well-drained soils, whereas, rough bluegrass is better adapted to shaded, moist soils.

Unfortunately, there are very few products that can be used to control moss. Products containing fertilizer and iron sulfate are sold at retail garden centers and can turn moss black and sometimes reduce encroachment Be sure to follow label directions so that these products are used safely and correctly. We have a free publication “Moss in the Lawn”. For a copy, please contact the Penn State Master Gardeners in Lackawanna County at (570) 963-6842 or email: LackawannaMG@psu.edu.
