Whether you planted seeds last fall, started seeds and cuttings over winter, or delayed all your milkweed plans until now, most of us will be spring planting some milkweed.
Spring is the time to execute your final (initial) milkweed plan for the season. Your milkweed patch(es) may need revising during the season, but starting with a good plan now should keep alterations to a minimum.
7 Spring Planting Tips for Magnificent Milkweed
1. Introduce Milkweed to Adoring Fans…with Pitchforks?
If you’ve started seeds indoors, remember to use an oscillating clip fan (or a floor fan) to promote stronger, straighter stems. Leggy seedlings won’t often survive planting outdoors, or grow up the way you would like.
We recently staked Asclepias erosa seedlings with a simple method that doesn’t require tying them to anything. We used this simple staking technique in addition to the fan:
You can break off fork handles to adjust the height for smaller seedlings.
Two species that are known to start leaning are Showy Milkweed and the peculiar-podded Balloon Plant , but you can use these techniques on other milkweed varieties or any plant species that is having a hard time staying vertically motivated…
2. Water First
Wet the soil before planting your seeds so they won’t be instantly washed away to a location of your unchoosing or try spring sowing milkweed seeds
3. Protect Your Weed
Fence off your seedlings if there is a good chance of trampling by overzealous pets or small children. You’ll be surprised to find that some garden pests (like rabbits) might even give your milkweed a nibble between mouthfuls of their favorite fresh veggies.

4. Root Cuttings in Water for at least One Month
Cuttings are easiest to take from non-native tropical milkweed. Place them in distilled water for a month or longer. Cuttings are much sturdier than seedlings so they’re unlikely to be wiped out by stormy weather or a storming of the garden by unwelcome pests.

5. Water Wisely
After planting, water your cuttings every few days until they’re actively putting out new growth. Although most milkweed varieties are drought tolerant, this doesn’t apply to your baby cuttings and seedlings.
6. Give Weed a Chance!
Are you sometimes too impatient waiting for milkweed plants to return in spring? 🤐 Don’t give up on milkweed too early and dig up perfectly good plants! A good rule of green thumb is to put all questionable plant replacements at the end of your gardening to-do list.
While you’re focused on other garden preparation, some of the perennial plants you wrote off for dead might just surprise you…🌱😊
7. Grow a Patch
Grow at least 6 plants together so your monarch caterpillars don’t run out of food. If you have lone plants growing around your yard, check them regularly and transfer monarch caterpillars to other milkweed, if necessary.
Most milkweed species require moderately acidic soil with optimal PH levels between 4.8 and 6.8. If you’re having problems growing milkweed, consider a PH testing kit to see if this is a problem.
8. Grow SEVERAL Patches
Grow patches in different areas of your yard and garden. Weather and wildlife are the ultimate wildcards in your milkweed’s performance. Within the same yard, these two wildcards can affect each patch differently.
A couple years back, a freak hail storm wiped out all the plants on the north side of our house, but left the south garden virtually untouched. Imagine if our entire milkweed supply had been planted on the north side…
Planting all your milkweed in one patch is like putting all your pastries in a cookie jar, and giving them to a binge-eating blue monster for safe keeping…
