North Carolina State University, North Carolina A&T State University, U.S. Department of Agriculture, and local governments cooperating. I am very excited to update the progress in our Discovery Gardens. At this point, the contractor should be done sometime this month! This phase of construction includes the Summer House (a pavilion over the pond, pictured above), the paths and walkways, and irrigation system. This will leave us with the ornamental pond, a gazebo, the Children s Garden and a whole lot of planting left to complete. When the contractor is done, the Master Gardener Volunteers will be hosting a series of planting days as we install the trees that will serve as the backbone of these gardens. The Onslow County Master Gardener Volunteers received a $4000 Tree Legacy Grant from the NC Urban Tree Forest Council to cover a portion of the tree purchase cost. We will be hosting a workshop on the Fundamentals of Tree Establishment on February 16 (see upcoming classes and events for details) and will be scheduling community planting days for the second half of February and in to March. Since we are dependent on the contractor and the weather, please contact the office directly if you want to be notified about the dates and times of the planting days. Even if you don t help plant, make sure you come out and visit the gardens and check out the progress we are making. The Discovery Gardens are located behind the Cooperative Extension office located at 4024 Richlands Highway (beside the Farmers Market). For more information or to join us on a planting day, call 910.455.5873 or send an email to lisa_rayburn@ncsu.edu.
Buying Seeds The seed catalogues are pouring in and it s easy to get caught up in the excitement. Before you start placing your order, take the following thoughts in to consideration. https://content.ces.ncsu.edu/extensiongardener-handbook/13-propagation First, read the label and determine whether the seeds will need an early start indoors. Cool season crops like broccoli and cabbage benefit from being started indoors so they are large enough to be transplanted out in the garden. Warm weather crops like tomatoes and peppers need to be started under lights inside so they are ready to go in the garden when the soil has warmed up and last frost is past. If you aren t up for starting your own seedlings indoors, you will want to wait and buy these plants as transplants. Vegetable crops that grow best when they are directly seeded in the garden include vining crops like beans and peas, root crops like radishes and carrots, and corn. The cucurbits (cucumbers, melons and squash) can go either way. Next, determine how much you need to buy. This will be dictated by the amount of garden space that you have and the spacing of the crop. It s ok if you buy a little extra. Fast-growing vegetables like lettuce, radish, spinach and beans can be planted several times throughout the season. If you have extras, many seeds store well from year to year but there are some exceptions. It is best to buy garden pea and onion seeds fresh each season. Store excess seeds in an air-tight container in a cool, dark, dry location. Consider your space. In a small garden, avoid space-hogging vegetables like sweet corn, pumpkins and watermelon. Instead, focus on higher-yielding, more compact vegetables like leafy greens, tomatoes, beans, herbs and peppers. For even more compact plants, look for varieties listed as bush, dwarf, patio or good for containers. While you are choosing varieties, consider the differences between heirloom, open-pollinated and hybrid varieties. If you want to save your own seed, heirloom and open-pollinated varieties will grow true from seed, year after year (as long as they are properly separated from other varieties of the same crop). New varieties are often hybrid varieties. This means that the variety was produced by crossing two distinct varieties. Hybrid varieties often have increased vigor, yield or disease resistance but you if you save the seed, you will not get consistency in the next generation. I know that many people are concerned about GMO-seeds. Right now, there are no GMO-seeds readily marketed to homeowners. You aren t going to accidentally buy them while cruising through your favorite homeowner seed catalogues. Look for disease resistant varieties, especially if you have had problems in your garden in the past. Most varieties are not resistant to all diseases, just to some. So make sure that you have disease problems accurately diagnosed. In our area, tomato spotted wilt virus and nematodes are common problems so look for tomato varieties with resistance to these problems. However, we don t have any readily available varieties that are resistant to southern bacterial wilt. If this disease has been a problem in your garden, you will want to move your tomatoes to a new location or consider growing them in containers in a clean potting mix. Check the days to harvest information for each variety as well. In our long growing season, a mix of short, mid and long season varieties will extend your harvest window without multiple planting dates.
You will want to include some flowers in your planting plan. Flowers add color and interest to the garden while serving as an important source of nectar and pollen for pollinator insects as well as the beneficial predatory insects that feed on problem insects in your garden. Cosmos, zinnia, marigolds, cleome, morning glory and sunflower are just a handful of the flowers that are easy to grow from seed. Sit back, enjoy reading all of your seed catalogues, develop your wish list and start coming up with a plan for this year s garden. Because it s time to order some seeds!

Tips and Tasks Prune back ornamental grasses and ground covers in early February before new growth starts. Add mulch to beds if needed. Scale can be a problem on hollies and other shrubbery outside and on house plants indoors. Scale are small, hardbodied insects that often look like bumps on the bark or leaves of the plant. Scale on landscape plants can be treated with horticultural oils. Follow the label directions and use the spray rate recommended for the time of year. Acephate (Orthene), carbaryl or insecticidal soap can also be used. Insecticidal soap is a good choice for scale on houseplants. A second treatment after two weeks is generally needed to control newly emerged scale insects. With any product, read and follow all label directions and remember that thorough coverage is critical for control. Armored scale on ornamental shrub https://johnston.ces.ncsu.edu/ Plants naturally change color in the winter and even evergreens like azaleas, gardenias and camellias can experience yellowing. Older leaves naturally yellow and drop off. If azaleas are discolored and the leaves show stippling (tiny discolored spots), spider mites could be the culprit. Spider mites can be controlled with horticultural oil or insecticidal soap. Dormant pruning of fruit trees and grapevines should be done in February as should heavy pruning and rejuvenation pruning of most ornamental shrubs. Remember to wait and prune spring flowering shrubs such as azaleas and forsythia after they bloom. If you are using a preemergent herbicide to control summer annual weeds (including crabgrass) in your lawn, aim to apply it around Valentine s Day. If these chemicals are applied too late, you will not get adequate weed control. Read and follow all label directions. Avoid weed-and-feed formulations and wait until mid-may to June to fertilize warm season lawns. If you are battling Florida betony, remember to apply herbicides in February before the plant starts developing its distinctive tubers. Remove leaves and debris from lawns. Do not burn St. Augustine, centipede, or zoysiagrass lawns. Irrigation is usually not necessary during the winter months. The optimum time to seed or lay sod for a warm season lawn is in the spring from about April until July 1. Plan your spring vegetable garden. Cool season crops need to be planted early enough to harvest before the heat of summer hits. Beets, broccoli, cabbage, carrots, cauliflower, kale, kohlrabi, lettuce, mustard greens, onion, garden peas, potatoes, radishes, spinach and turnips can all be planted in February for spring harvest.
