Spring Planting Parties

Easy Fall Planting

Fall is the second-best time to plant – with some saying it’s the best!

We typically have late-summer and fall sales. Check out current plant sales here.

LATE-FALL SOWN PERENNIAL SEEDS

Sow perennial plant seeds, that need stratification, after a hard frost – below 25 F. Stratification is the process of seeds being in a cold environment and then breaking dormancy once the weather warms. This ensures that they will not sprout until the following spring.

Be sure to mark the spot you planted. If we have a dry winter and less rain in the spring, make sure to water your seeds in the spring to keep soil moist.

Perennial plants to sow after a hard frost:

• Blue and Breezy Flax Seeds
• Forget-Me-Not
• Hyssop
• Lavender
• Russell Lupine Blend
• Milkweed
• Penstemon
• Sundial Lupine Bluebonnet
• Colorado Blend Yarrow

LATE-FALL SOWN ANNUAL SEEDS

You’ll get earlier blooms and reduce time in the late winter/early spring sowing seeds indoors. The moisture from melting snow will greatly reduce your need to water in the spring.

Tips for sowing annual seed:

Sow the seeds after a killing freeze and before snowfall. You may also sow in late-winter between snow fall. The snow buries the seed and insulates them, helping to retain moisture.

Mix the seed with a bit of sand before sowing. This helps the seed spread evenly and gives you a better visual of where you have sown.

Mark where you planted with labeled garden stakes to avoid damaging emerging flowers.

Annuals plants to sow after a hard frost:

• Bachelor Buttons
• California Bluebells
• Bluebonnet
• Larkspur
• Poppy

GARLIC

Garlic is one of the easiest to grow crops. Garlic is planted in the fall. They start to grow their roots this fall and then emerge next spring. We recommend adding compost to your planting area two weeks before planting your garlic.

FALL-PLANTED FLOWER BULBS

Bulbs are really as easy as dig, drop, and done. When planting, make sure the soil is well-draining (soil doesn’t stay soggy more than a day) and use Bulb Tone to get their roots off to a healthy start before the ground freezes. Amend your soil with compost or top soil if it’s compacted or not well-draining.

If you have a presence of voles, mice, chipmunks, or squirrels we recommend planting them with a granular animal repellent.

LANDSCAPE PLANTS

Fall is a wonderful time to plant in you landscape. The heat of the summer is done and the cooler weather is less stressful for the plants during transplanting. The soil also stays moist longer, there is less disease and pest stressors, and your plants will put more energy into root growth than foliage.

We recommend mulching around your new landscape plants, leaving a couple inches open around the stems to help retain moisture when they are establishing themselves.

PLANT TREES, SHRUBS, AND EVERGREENS

Trees, shrubs, and evergreens can be planted up to 6 weeks before ground freeze (average ground freeze is beginning of Dec.). If the trees or shrubs are dormant by the time of planting, you may not need to water if the soil stays slightly moist. Make sure to mulch 2-3 inches around the root zone and wrap your tree saplings Oct. 31st or as soon as possible after that.

Deeply water your plants until the ground freezes. Only water when the top 2 – 3 inches are dry. It’s usually 5 gallons of water every week to two weeks depending on your soil type, size of the plant, and weather.

PLANT PERENNIALS

You can plant perennials up to 6 weeks before ground freeze (average ground freeze is beginning of Dec.) but sooner the better for transplanting success. Just make sure they are watered until freeze and heavily mulched after ground freeze to protect their roots.

When planting, mix in a slow release fertilizer – like Biotone. When the top couple inches of soil are dry, that’s when you should water. Water deeply so the plant roots reach deeper into the soil and create a more robust root system before winter weather.

DIVIDING PERENNIALS

Dividing perennials (PDF List of perennials and dividing time):
These cooler days are perfect for dividing perennials. Divide or move perennials if they are crowded or not performing well in their original spot.

A good rule of thumb to follow:
“Blooms late-summer/fall, divide them in spring. Blooms spring, divide in the fall.”

REDUCE WINTER DAMAGE

If you have issues with rabbits or deer around, get a hard plastic mesh tree guard. You’ll be happy you did because if animals chew around the entire tree diameter, it’ll cut off nutrients to the tree, which will cause the plant to die. Shrubs and evergreens can also experience animal damage from hungry animals so use a granular or spray animal repellent or fencing.

Here is an extra note about evergreens. It’s very important evergreens have adequate water before ground freeze or you may experience browning of needles the next spring. Evergreens do better when planted early fall instead of late fall to help them take up moisture before freezing. They slowly lose water from their needles over winter and if they are in an area of high winds and/or bright, all day sun, it dries them out quicker.

SOWING TURF GRASS

Mid-August through mid-September is an ideal time to start new grass from seed. We carry high quality seed from Ramy Seeds in Mankato. If it seems daunting to keep the soil moist to sprout grass this time of year or it’s too late, you can wait until late fall – after we have our first frosts – to sow seeds that will sprout in the spring when the weather warms and spring rains help keep the seed moist.

PLANT COVER CROPS AFTER HARVEST

Cover crops are also an option if you are done with your garden space until next spring or before you plant garlic in late Sept. or Oct. It’s best to start growing cover crops as soon as you can but many crops will grow into late fall. Plant a quick growing crop like peas, oats, radishes, or buckwheat.

A cover crop is used to slow erosion from wind and rain, improve soil health, smother weeds, help control pests and diseases, break up compacted soil, and increase biodiversity. Using a cover crop can reduce the amount of compost you need to prepare your garden soil for next year.

Read our post about Living Soil which covers best practices for healthier soil and head over to the University of MN Extension article with a cover crops selector tool to choose a cover crop for your soil goals. For example: If you fertilize with liquid fertilizers you probably have excess nitrogen in your soil or if you grew peas ( nitrogen fixers) in an area then you’d choose a cover crop that adds other nutrients.
