Correct Timing for Spring Yardwork

It has been exceptionally warm so far this year. We haven’t had a lot of snow events yet and the weather has already hit the 70’s on multiple occasions. However, it is still too early to go out and do too much to your gardens, we could still face rather cold temperatures and possibly even snowy conditions yet this spring. So, I wanted to take the time to go over when the best time for garden preparations should begin.

2014-03-04 11.18.22Vegetable gardens are always a favorite of mine in the spring and summer for delicious homegrown crops. Potatoes and Peas can be planted in late March to early April. Other cool season crops should be planted in early to mid-April. We can start seeds for transplants for summer crops at this time. Begin seedlings 10 weeks prior to transplanting for slow growing plants such as broccoli, lettuce, and cabbage. Allow for 6-7 weeks of growth for new seedlings prior to transplanting for plants such as tomatoes, peppers, and eggplant. And you only need to plant those fast growing species such as cucumbers, squash, and the melons 2-3 weeks in advance of transplanting. Remember, transplanting should occur no sooner than mother’s day, which is May 8th this year.

Turf can be overseeded or reseeded from the end of March through the beginning of April. We still need to wait until then to overseed, because with this early warm weather it may cause some to germinate and cold night temperatures could kill those young plants. Be sure that you are buying certified weed free seed. The best grass choices for eastern Nebraska are either 100% tall fescue, 90% tall fescue with 10% Kentucky bluegrass, 100% Kentucky bluegrass, or 100% buffalograss as a warm season grass choice. Mixes are fine to use in Nebraska, but you want to make sure it is a good mix. If you purchase a mix, avoid any that contain annual bluegrass, ‘Linn’ perennial ryegrass, or ‘Kenblue’ Kentucky bluegrass. Crabgrass preventer should not be applied until later April when the soil temperatures have warmed up. Don’t use crabgrass preventer on newly seeded lawns until you have mowed 3 times on the newly seeded grass.

Wait to uncover your perennials this spring. The mulch applied around the perennials in the winter is not meant to keep the plants warm, it is meant to keep the plants at a uniform temperature throughout the growing season. If you leave the mulch on in these warm days, this will help to keep your plants cold, and therefore, help them maintain their dormancy. The same goes with roses that were placed under rose cones in the fall. Leave those cones on as long as you can.

We may have plants that break dormancy early with all of these warm temperatures. This may cause some dieback on the branches or stems and most likely these plants will survive. The bigger problem will be with plants that fruit such as strawberries or fruit trees. If these plants break dormancy and start to bud their buds may be damaged by a freeze event and then the plants will not produce fruit. Fruit trees cannot be discouraged from this occurrence, which is why we often have problems with low or no fruit on peaches and apricots with a late freeze event.

Spring Preparations for Lawn and Garden

2013-05-09 10.17.11

We have finally reached March, and the beginning of spring is right around the corner. We don’t want to get out and do too many things in our yards and gardens too early in the year, but there are some things to bring you out of cabin fever. Here is a listing of our usually spring activities and when the best time to do them would be.

We can now begin to start our seeds indoors for transplants into our gardens later in the spring. Remember, we want to wait until Mother’s Day to plant most of our vegetables outside, unless they are cool season crops. You should start things like broccoli, cauliflower, cabbage, and head lettuce indoors about 10 weeks prior to transplanting outside. Other plants such as tomatoes, peppers, and eggplants can be started indoors 6-7 weeks in advance of planting outdoors. Vegetables such as watermelons, cantaloupe, cucumbers, zucchini, squash, and beans should be planted from seed directly into the garden in May. Peas and other cool season vegetables can be planted in the middle to the end of March. The saying is that you can plant your peas and potatoes on St. Patrick’s Day, or some say Good Friday. Either day would be fine to plant your peas and potatoes from the middle to the end of March.

Roses can also be pruned back at this time of the year. The best time to prune roses is February to March or in early spring. When you prune your roses, start by removing all the dead, diseased, or damaged branches.   If it is a dead or diseased branch, cut back at least one inch below the dead area and above a live bud. If there are no live buds, cut the entire cane out. After that, you should prune up to one-third of the older branches and canes.

Other types of shrubs can be pruned next month, in April. Things such as honeysuckle, ninebark, barberry, and burning bush should be pruned in the early spring. To prune these types of shrubs, we should cut out the older canes and ones that are dead. As with roses, we need to make sure that we are only cutting out one third of the plant. If it is a plant that blooms in the spring, such as forsythia, lilac and spring-blooming spirea, we should wait to prune it until just after it has flowered.

Turf can be overseeded or reseeded from the end of March through the beginning of April. Be sure that you are buying certified weed free seed. The best grass choices for eastern Nebraska are either 100% tall fescue, 90% tall fescue with 10% Kentucky bluegrass, 100% Kentucky bluegrass, or 100% buffalograss. Mixes are alright to use in Nebraska, but you want to make sure it is a good mix. If you purchase a mix, avoid any that contain annual bluegrass, ‘Linn’ perennial ryegrass, or ‘Kenblue’ Kentucky bluegrass. After you have mowed one time on the new seed, you can then put your crabgrass pre-emergent herbicide down to control crabgrass for the year. Wait to use 2,4-D products on your newly seeded lawn areas until after you have mowed at least three times on the new turf.
