Growing Tulips
-
Date Posted: Fri, Mar 21 - 1:01 am
- I have a beautiful pre-planted set of tulips that I would like to plant in my garden. I am wondering if I should put them in a pot or plant them in the ground. What are the ideal soil conditions, watering regimen, and how much sunlight should they get? My front yard gets great partial sun and my backyard gets full sun. Thank you in advance for your help!
- Tulips are beautiful! What a great addition to your garden! Here are some tips to give your tulips the best chance of thriving, whether you choose a pot or in-ground planting. Planting in a Pot or in the Ground? Pot: Great if you want to control soil conditions and move them around for optimal light. Just make sure it has good drainage. Ground: Ideal for long-term growth, although some tulips may not return year after year in Virginia’s warm climate due to the lack of a cold dormancy period. If you want to replant them for future years, the ground is best. If you just want them for this season and might replace them next year, a pot is a great choice. I'm not exactly sure what you mean by pre-planted, but if they are already in a pot, I would leave them there for now and let them bloom. The ideal time to plant tulip bulbs is in the fall, generally late October to early December. They have a tendency to rot in warm, wet conditions. Ideal Soil Conditions: Tulips hate wet feet and need well-draining soil. To achieve this, it is best to amend heavy clay with sand or compost in order to improve drainage. They also like slightly acidic to neutral soil (pH 6.0–7.0). (You could pick up a soil test kit from one of the Richmond libraries to find out what your pH is!). Watering Needs: Water well after planting to help them establish roots. During growth, only water if the soil is very dry - tulips prefer dry conditions between watering. After blooming, reduce watering as the the foliage dies back to prevent bulb rot. Sunlight Requirements: Full sun (backyard) is ideal, especially for strong blooms next year. Partial sun (front yard) is okay, but tulips bloom better with at least 6 hours of direct sun. If you plant in a pot, you can move them to maximize sunlight exposure. Extra Tips: If you want them to return next year, wait until the leaves completely yellow and die back before cutting them—this allows energy to return to the bulb. Tulips sometimes don’t rebloom well in warm climates like Virginia, so many gardeners treat them as annuals and replant fresh bulbs each fall. The variety you select can have a big impact on this. Choose good quality, large bulbs with a reputation for dependability. Consider Darwin, Triumph or Emperor varieties. Good luck and happy gardening!

Finding Natives for a tough spot
-
Date Posted: Mon, Mar 17 - 4:33 pm
- Hello! We have a particularly difficult section of our garden in Richmond: it's a sloped spot between the driveway and the house, faces south, has pretty lousy soil, and is shaded by nearby oak tree. The only thing that we've been able to grow there is rosemary; everything else we've tried hasn't made it. Are there any native perennials that might survive?
- That sounds like a tricky spot, but there are some native perennials that could thrive in those conditions! Given that the area is south-facing but shaded, has poor soil, and is on a slope, you'll need plants that are drought-tolerant, shade-tolerant, and able to handle soil erosion. Here are some great Virginia native perennials that might work: Low-Maintenance Shrubs American Beautyberry (Callicarpa americana) – Handles some shade and poor soil, and has striking purple berries in fall. Witch Hazel (Hamamelis virginiana) – Tolerates shade and provides late fall yellow blooms. Perennials for Shade & Dry Conditions Columbine (Aquilegia canadensis) – A beautiful, drought-tolerant flower that does well in partial shade. Wild Geranium (Geranium maculatum) – A tough native with lovely pinkish-purple flowers in spring. Golden Ragwort (Packera aurea) – Great for erosion control and pollinators, with bright yellow flowers in spring. Ornamental Grasses (For Texture & Erosion Control) Little Bluestem (Schizachyrium scoparium) – Drought-tolerant and provides great fall color. (A favorite of mine!) Bottlebrush Grass (Elymus hystrix) – A native grass that thrives in dry shade. Since rosemary has survived, that suggests it’s well-drained soil, possibly a bit alkaline due to the concrete driveway. You may need to amend the soil with compost to help native plants establish, but once they do, they should require little maintenance.

Soil Testing
-
Date Posted: Mon, Mar 17 - 4:26 pm
- Can I bring a sample of my yard soil to the Extension office to be tested for heavy metals, etc.?
- This is a great question! Soil Test Kits are provided by the extension office and the Master Gardeners distribute them to the Richmond Public Libraries. We actually just got some in that we will be distributing this week! Each kit provides instructions for collecting and submitting the samples. Results are then emailed to you, typically within 3 working days of receipt. The routine test package includes soil pH,P,K,Ca,Mg,Zn,Mn,Cu,Fe,B, and estimated CEC, plus a fertilizer and lime recommendation. Testing for soluble salts and organic matter is also available. If you are looking for a way to test for the toxic heavy metals or metals related to pollution issues, send us an email at rvamastergardeners@gmail.com For this type of testing, Virginia Tech recommends connecting with your local extension agent. The City of Richmond has been without an extension agent for several years now, but we will try to get you connected to the appropriate people if this is the type of testing you are looking for.

Wildflower Seedballs

Date Posted: Fri, Mar 14 - 12:46 pm
- My club, at VCU will be hosting a seed ball making event next week Monday! We were hoping to use wildflowers and other small foliage that should grow with wildflowers native to the capital region. could you share knowledge or knowledge of resources with us? Maybe where we could acquire seeds for cheap/nothing as well as tips on how to go about planting the seed balls?
- Hosting a seed ball-making event is a fantastic initiative to promote native wildflowers and support local ecosystems in the Richmond area. Here's some guidance to help your club prepare: 1. Selecting Native Wildflower Seeds: Choosing species native to Virginia ensures that the plants are well-adapted to the local environment and provide optimal benefits to pollinators and other wildlife. Consider incorporating the following native wildflowers into your seed balls: Butterflyweed (Asclepias tuberosa): A perennial that serves as a host plant for monarch butterflies and blooms from April to September. Black-eyed Susan (Rudbeckia hirta): A versatile plant that can be annual, biennial, or perennial, attracting birds like the American goldfinch and blooming between June and October. Wild Bergamot (Monarda fistulosa): This perennial attracts butterflies, bees, and hummingbirds, with blooms from June to September. Smooth Blue Aster (Symphyotrichum laeve): A perennial that serves as a host plant for the pearl crescent butterfly, blooming from August to October. 2. Acquiring Seeds at Low or No Cost: Virginia Native Pollinator Seed Packets: The Virginia Department of Wildlife Resources offers seed packets containing native wildflowers suitable for various regions in Virginia. These mixes are designed to benefit pollinators and enhance local biodiversity. Seed Libraries: In the fall, the Master Gardeners collected many native seeds from the Amelia Street Urban Forest and shared them in the seed library at the Main Branch Richmond Public Library. I haven't checked back recently, but you are welcome to use whatever is left there! There are many other seed libraries around the city, some may have wildflower seeds in them VCU Office of sustainability: If you are not already connected with them, they would potentially be a good resource for helping you source free or low cost seeds. 3. Tips for Making and Planting Seed Balls: This website has two great recipes for making seed balls, one using paper as a base, and the other using soil and flour: https://chicagocommunitygardens.org/2020/04/22/for-earth-day-or-any-day-make-a-seed-bomb/ For planting tips, this will ultimately depend on what seeds you end up getting. Some seeds do best getting planted in the fall in order to go through a cold stratification. And others will be successful if planted this spring. Seed balls can be placed on soil just before rain and the precipitation will help distribute them into the soil and aid in germination. 4. Additional Resources: Plant Virginia Natives (pantvirginianatives.org): This initiative provides comprehensive information on native plants, including where to purchase them and guidance on creating pollinator-friendly habitats. Keep Virginia Beautiful (keepvirginiabeautiful.org): This organization offers resources and initiatives aimed at enhancing Virginia's natural and scenic environment, including distributing wildflower seed packets to promote beautification and support pollinators. Good luck with your seed ball making event! We will keep an eye out around the city for more native flowers to pop up :)

Growing Herbs

- How to grow healthy Herb plant? Plants like Basil, cilantro, Rosemarys.
- Growing herbs is so rewarding! I love having what I need for a recipe growing outside the back door! Basil, cilantro, and rosemary each have their own needs, so here’s a quick guide to help them thrive: Basil: Loves warmth and the sun and needs at least 6–8 hours of direct sunlight daily, prefers well-draining, nutrient-rich soil, keep the soil consistently moist but not soggy — water when the top inch feels dry, pinch off the top leaves regularly to encourage bushy growth and prevent flowering (which can make the leaves bitter), snip stems just above a leaf pair — this helps the plant grow fuller. Cilantro: Prefers cooler weather and about 4–6 hours of sun, this is a great spring and fall plant but typically doesn't survive in Virginia summers, too much heat can make it bolt (flower) quickly, likes loose, well-drained soil with some compost mixed in, water regularly to keep the soil evenly moist, but avoid waterlogging, cilantro grows fast — consider planting seeds every few weeks for a continuous harvest. Rosemary: Thrives with at least 6–8 hours of full sun, prefers sandy, well-drained soil — it hates sitting in water, let the soil dry out between waterings. Rosemary prefers to stay on the drier side, trim regularly to keep the shape and encourage new growth, there is a lot of Rosemary in our area that survives the winter, but its not a big fan of winter and does best if its in a warm sunny spot or you could bring it inside for the winter. Happy gardening! Enjoy your herbs!

- Learn basics of gardening
- It’s wonderful to hear that you’re interested in learning more about gardening! Starting out can feel a bit overwhelming, but with the right resources and a little patience, it can be incredibly rewarding. Here are a few first steps and resources to help you get started: 1. Understand Your Growing Zone: Knowing your USDA Hardiness Zone will help you choose the right plants for your area. The City of Richmond and nearby areas are in the 7b zone. (If you are outside of the city you can find your zone here by entering your zip code: https://planthardiness.ars.usda.gov) 2. Start Small: Consider beginning with a small garden bed, container garden, or even a few pots on a patio. Herbs, lettuce, and tomatoes are great starter plants! 3. Soil Health is Key: Good gardening starts with good soil. We always recommend getting a soil test to help understand what amendments you might need. Soil test kits are provided by the Master Gardeners through the Extension Office at many of the Richmond Public Libraries. 4. The Extension office has a lot of resources available through their website https://ext.vt.edu/lawn-garden.html and also by following their social media accounts @virginia_cooperative_extension 5. There are many gardening classes offered throughout the greater Richmond area, especially as spring arrives. You can look for classes at our local nurseries like Sneeds, Strange's and many others. Also, Lewis Ginter often has many gardening classes. 6. One of my favorite vegetable gardening books is "Grow Great Vegetables in Virginia" by Ida Wallace. This book is specific to our area and offers a lot of great step by step guidance for each month. Gardening is a rewarding hobby that helps you connect with nature, reduce stress, and enjoy the satisfaction of watching things grow. Whether you’re growing flowers, vegetables, or herbs, it brings beauty, peace, and a sense of accomplishment. I always think of it as an experiment too. Each year I learn things that worked well, as well as things that didn't. Good luck, and have fun!
