Fenced garden

Hello, Everyone! Gardening season is off to a challenging start with dry weather, insect pests and heat. If your garden is not looking great, you may find comfort in knowing you are not alone.

We have received many questions regarding failed gardens this year, ranging from poor seed germination to seedlings lacking vigor to insect pests.

In a good year, seed germination rates should be well above 85% for most crops. This year, I have seen germination rates as low as 25%. I attribute most of the poor germination to poor planting conditions.

Wet weather early this spring delayed garden preparation, and some gardeners worked the soil while it was too wet. When you run a tiller through wet soil, you create mud clods that are hard to break down with further tilling. When these clods dry out, they can feel and act much like concrete.

Instead of a nice seedbed maximizing seed to soil contact, the seeds will fall through the clods and have poor soil contact. Seeds will take up less water in these environments preventing germination, and if they do germinate they are more likely to dry out.

Even if you waited for the perfect conditions, and created a perfect seed bed, heavy rains could have caused soil surface crusting. Crusting is caused by heavy rain that compacts the top layer of soil. Heavy rain also moves smaller soil particles into gaps in the soil surface sealing it off.

As seeds germinate and begin to grow toward the soil surface, they may not be able to break through the crust to reach sunlight. You can prevent crusting by increasing soil organic matter with the addition of compost, utilizing cover crops and reducing tillage.

You can also gently rake the soil surface to break up the crust, but you will need to do this immediately after the rain. Once seedlings become stalled at the soil surface, they will quickly use the remaining energy from the seed.

The poor planting conditions mentioned above can lead to reduced root formation. Without a good root system, plants cannot take up water or nutrients to promote growth, and it is especially important in hot and dry weather.

During dry conditions, we also tend to see more frequent nutrient deficiencies. This may not necessarily be due to inadequate nutrient levels in the soil, but there is not enough water to move the nutrients to the root zone. It is a good idea to test your soil on a regular basis so you know your current nutrient levels.

We are also dealing with relatively higher insect pressure than previous years. This is likely due to our warm early spring that encouraged the emergence of insects two to three weeks earlier than normal.

If it feels like there are more bugs this year, you may be right. Instead of seeing a steady emergence of insect species during the spring and summer, they emerged closer together making it seem like we are in an insect invasion.

Before you reach for the bottle of insecticide, make sure you know the good bugs from the bad. Also read the label. Over the last several years, popular brands have changed their active ingredients.

Even though you buy your favorite name brand pesticide, what’s inside the bottle may be different. Be sure to read the label to find updated application rates, target species, and suitable crops.

If you have any questions about your gardens, OSU Extension and the Trumbull County Master Gardener Volunteers are here to assist. Give us a call at 330-638-6783, drop off samples at our office in Cortland, or send an email.

Labor has always been an issue, mainly because we are a seasonal operation. So that's a challenge finding somebody who only wants to work three months out of a year, sometimes up to six months.

I appreciate the benefit of having a strong voice in my corner. The extras that are included in membership are wonderful, but I'm a member because of the positive impact to my local and state agricultural communities.

I see the value and need to be engaged in the community I live in, to be a part of the decision-making process and to volunteer with organizations that help make our community better.

The plan we are on is great. It’s comparable to my previous job's plan, and we are a sole proprietor.

We work terrifically with the Ashtabula County Farm Bureau, hosting at least one to two outreach town hall events every year to educate new farmers and existing farmers on traditional CAUV and woodlands.

Knowing that horticulture is under the agriculture umbrella and having Farm Bureau supporting horticulture like it does the rest of ag is very important.

If it wasn't for Farm Bureau, I personally, along with many others, would not have had the opportunity to meet with our representatives face to face in Washington.

So many of the issues that OFBF and its members are advocating for are important to all Ohioans. I look at OFBF as an agricultural watchdog advocating for farmers and rural communities across Ohio.
