New Mexico’s high altitude means rhubarb planting occurs earlier than in lower elevation states. Knowing the best time to plant rhubarb in new mexico is the key to a successful harvest in this unique climate.
Rhubarb is a cool-season perennial. It needs a period of winter chill to produce well. In New Mexico, the timing is all about working with the frost dates and the intense sun.
This guide gives you the exact planting window. You will learn how to prep your soil, care for your plants, and avoid common mistakes. Let’s get your rhubarb patch started right.
Best Time To Plant Rhubarb In New Mexico
The ideal window for planting rhubarb in New Mexico is from mid-March to mid-April. This timing works for most of the state, from Albuquerque to Santa Fe and Las Cruces.
Why this window? The soil needs to be workable but not frozen. You want the crowns to settle in before the heat of late spring arrives. Planting too late stresses the young plants.
Here is a quick breakdown by region:
- Northern NM (Santa Fe, Taos): Aim for late March to mid-April. Higher elevations mean later frosts.
- Central NM (Albuquerque, Los Lunas): Mid-March to early April is perfect.
- Southern NM (Las Cruces, Deming): You can plant as early as late February to mid-March. The growing season is longer.
Always check your local frost dates. The last spring frost in New Mexico can be as late as May 1 in the north. Rhubarb is frost-tolerant, but young shoots can be damaged by a hard freeze.
Why Timing Matters So Much In New Mexico
New Mexico’s high altitude creates intense sunlight and wide temperature swings. Daytime temps can be warm, but nights stay cool. Rhubarb loves this, but only if planted at the right time.
If you plant too early, the ground may be too wet or frozen. The crowns can rot. If you plant too late, the heat stresses the plant. It may not establish a strong root system before summer.
The best time to plant rhubarb in new mexico balances these factors. You want cool soil (around 40-50°F) for root growth, but not freezing conditions.
Understanding Rhubarb’s Growth Cycle
Rhubarb is a perennial that needs a dormancy period. It requires about 500-1,000 hours of temperatures below 40°F to break dormancy. New Mexico’s cold winters provide this naturally.
Once planted, the crown sends up shoots in early spring. The stalks grow quickly in the cool weather. Harvesting begins in the second year. The first year is all about root establishment.
Do not harvest any stalks in the first year. Let the leaves photosynthesize to feed the roots. This builds a strong plant for future years.
How To Plant Rhubarb In New Mexico Soil
New Mexico soil is often alkaline and low in organic matter. Rhubarb prefers a slightly acidic to neutral pH (6.0-7.0). You need to amend the soil before planting.
Follow these steps for success:
- Test your soil pH. Kits are cheap at garden centers. If pH is above 7.5, add sulfur or peat moss.
- Choose a full sun spot. Rhubarb needs at least 6 hours of sun daily. In southern NM, some afternoon shade helps.
- Dig a wide hole. Make it 2 feet wide and 1 foot deep. Loosen the soil around it.
- Mix in compost. Add 2-3 inches of well-rotted compost or aged manure. Mix it into the native soil.
- Plant the crown. Place the crown so the buds are 1-2 inches below the soil surface. Do not bury it too deep.
- Space plants 3-4 feet apart. Rhubarb spreads. Give it room to grow.
- Water thoroughly. After planting, give it a deep soak. Keep the soil moist but not soggy.
Preparing For New Mexico’s Climate Challenges
The intense sun and dry air in New Mexico can stress rhubarb. Mulching is essential. Apply a 2-3 inch layer of organic mulch (straw, wood chips, or compost) around the plant.
Mulch keeps the soil cool and moist. It also suppresses weeds. In summer, it protects the roots from heat. In winter, it insulates against freeze-thaw cycles.
Water deeply once a week during the growing season. In sandy soils, you may need to water twice a week. Rhubarb is drought-tolerant once established, but consistent moisture gives better stalks.
Choosing The Right Rhubarb Variety For New Mexico
Not all rhubarb varieties perform well in New Mexico’s climate. Some are better suited for heat and dryness. Here are top picks:
- Victoria: A classic, reliable variety. It is heat-tolerant and produces thick, green stalks.
- Canada Red: Known for its deep red color and sweet flavor. It does well in cooler areas of the state.
- Raspberry Red: A vigorous grower with bright red stalks. It handles heat better than some red varieties.
- Valentine: A newer variety with excellent heat tolerance. It is a good choice for southern New Mexico.
Avoid varieties that are bred for very cold climates, like ‘Crimson Cherry’. They may not handle the heat stress as well.
Caring For Rhubarb Through The Seasons
Once planted, rhubarb needs minimal care. But a few key tasks ensure a long-lived patch. Here is a seasonal care guide.
Spring Care
As soon as the soil thaws, remove winter mulch. Apply a balanced fertilizer (10-10-10) around the plants. Water it in well.
Watch for new shoots. If a late frost is forecast, cover the young shoots with a frost cloth or old sheet. They can handle light frost, but a hard freeze kills the tender growth.
Thin the stalks if they are too crowded. Remove any that are thin or spindly. This directs energy to the stronger stalks.
Summer Care
Summer in New Mexico is hot and dry. Keep the mulch layer thick. Water deeply once a week. In extreme heat, water twice a week.
Remove flower stalks as soon as they appear. Rhubarb sends up seed stalks in late spring. Cutting them off directs energy back to the roots and stalks.
Do not harvest in the first year. In the second year, harvest for only 4-6 weeks. In the third year and beyond, you can harvest for 8-10 weeks.
Fall Care
Stop harvesting by early August. Let the plant build up energy for next year. The leaves will die back after the first frost.
After the leaves die, cut them off at ground level. Remove any debris to prevent disease. Apply a fresh layer of compost or aged manure around the crown.
Add a winter mulch layer (straw or leaves) after the ground freezes. This protects the crown from temperature swings.
Winter Care
Rhubarb is dormant in winter. It needs the cold period. Do not water during dormancy. The mulch will protect it.
If you have potted rhubarb, move the pot to a sheltered spot. Bury the pot in the ground or wrap it with insulation. Potted plants freeze faster than in-ground ones.
Common Problems When Growing Rhubarb In New Mexico
Even with perfect timing, issues can arise. Here are the most common problems and how to fix them.
Bolting (Flowering)
Rhubarb bolts when stressed by heat or drought. The plant sends up a tall flower stalk. This reduces stalk production.
Solution: Remove flower stalks immediately. Keep the soil consistently moist. Mulch heavily to keep roots cool.
Thin, Spindly Stalks
This often means the plant is too young or the soil is poor. It can also happen if the plant is overcrowded.
Solution: Do not harvest in the first year. Divide mature plants every 5-7 years. Add compost annually.
Leaf Spot Or Fungal Diseases
New Mexico’s dry climate reduces fungal issues, but they can happen in wet springs. Look for brown or yellow spots on leaves.
Solution: Remove affected leaves. Improve air circulation by thinning stalks. Avoid overhead watering.
Pests
Rhubarb is generally pest-free. Occasionally, slugs or snails may appear. In New Mexico, aphids can be a problem in hot weather.
Solution: Use diatomaceous earth around the base for slugs. Spray aphids off with a strong stream of water.
Harvesting Rhubarb At The Right Time
Harvesting starts in the second year. The stalks should be at least 12-18 inches long. They should be firm and thick.
Do not cut the stalks. Instead, grasp the stalk near the base and pull it gently. It should snap off cleanly. Leave at least half the stalks on the plant to keep it healthy.
Harvest in the morning when the stalks are crisp. The flavor is best then. Stop harvesting by early August to let the plant recover.
Storing And Using Your Rhubarb
Fresh rhubarb lasts about a week in the refrigerator. Wrap it in a damp paper towel and put it in a plastic bag. Do not wash it until you are ready to use it.
You can freeze rhubarb for later use. Chop it into 1-inch pieces. Spread them on a baking sheet and freeze. Then transfer to a freezer bag. It will keep for up to a year.
Rhubarb is tart. It pairs well with strawberries or apples. Use it in pies, crisps, jams, and sauces. The leaves are toxic, so discard them.
Frequently Asked Questions
Can I plant rhubarb in the fall in New Mexico?
Fall planting is risky in New Mexico. The plant needs time to establish before winter. Spring planting is much more reliable. If you try fall, plant in September and mulch heavily.
How long does rhubarb live in New Mexico?
With proper care, a rhubarb patch can produce for 10-15 years. Some plants live longer. Dividing every 5-7 years keeps them productive.
What is the best fertilizer for rhubarb in New Mexico?
A balanced 10-10-10 fertilizer works well. Apply in early spring. Avoid high-nitrogen fertilizers, which encourage leaf growth over stalks. Compost is also excellent.
Do I need to water rhubarb in the winter?
No. Rhubarb is dormant in winter. Watering can cause rot. Let the natural snow and rain handle it. If it is a dry winter, a light watering once a month is fine.
Can rhubarb grow in containers in New Mexico?
Yes, but it is challenging. Use a large container (at least 18 inches deep and wide). Use a quality potting mix. Water more frequently. Protect the container from extreme heat and cold.
