SPRING: Month by Month Gardening To-Do List
The average first frost date for Collin County is November 15. The average last frost date is March 15. Frisco, Texas gets and average of 39 inches of rain per year. On average, there are 230 sunny days per year in the city. The average July high is around 96 degrees. The average January low is 33 degrees.
- Cool Season Annual Color — for the first part of the month (Petunias, Alyssum, Dianthus & Snapdragons). We have plenty in stock! Remember, we still have the possibility of freezing temps this month so it’s best to wait on summer annuals…we know it’s hard to wait!
- Herbs, Perennials, Shrubs & Trees can be planted now as well. Check with us on veggies, either plants or seed — there’s just too many to list! See our “Vegetable Gardening Guide.”
- We have a great selection of the BEST and HARDIEST varieties of trees for our area. All of our B&B trees are grown locally at our tree farm in Collinsville, TX. New arrivals include: Chinese Pistache, Live Oak, Red Oak & other hard-to-find Ornamental Trees.
PRUNE: You should trim your perennials back to clean-up, shape and control their size now. Cut back groundcovers, such as Asian Jasmine, Euyonomous colorata, Liriopes & even Frogfruit, by as much as one-half to let fresh new growth emerge.
FERTILIZE: Spread Texas Tee 6-2-4 on your entire yard if you did not last month. Use Superthrive on newly planted plants for a good start…and even on houseplants or potted plants. For more info on tree feeding, check out our article “How to Fertilize Your Tree” from the Education Center.
WATER: Only when absolutely necessary! We receive ample rain during the spring and do not need to run irrigation systems. Please follow your city’s watering guidelines.
PESTS: Watch for slugs on the ground, fire ant mounds, aphids on new growth and canker worms in your trees. Pest identification is key for proper control. Bring a sample (inside a container or small plastic baggie, please!) to the nursery & we can assist with identification. Remember, over 90% of bugs are good citizens!
PLANT: Annual Color and Perennials Now! We specialize in Native Texas Perennials and our selection is OUTSTANDING! You can still plant Trees, Hollies, all Shrubs, Roses, Vines & Groundcovers. Tropicals are coming in now and the selection will grow as the season permits. Brighten your Porch with a beautiful Color Bowl or Hanging Basket arranged by our staff! Want to get your hands dirty? Then come and build your own color bowl from our large annual selection!
FERTILIZE: Our fist choice is Gardenville 7-2-2 if you did not apply in February or March. If you procrastinated, it’s okay…it’s organic! Avoid using Weed & Feed products. We do not recommend them or trust them. Foliar feed your plants as they begin to grow with Liquid Fish or Liquid Seaweed, Garrett Juice or Johns Recipe. Apply Colorscapes or ColorStar when planting your annuals, perennials and color bowls. Re-apply ever 4-6 weeks to keep your plants green & blooming!
- Cankerworms – be on the lookout! These larva hang from your trees on thin, almost transparent threads and can strip trees of their new foliage. Use Bacillus Thurengiensis (BT) as a biological control. BT can be sprayed on your junipers and other needled evergreens to control Bagworms. For Slugs use Sluggo or Sluggo Plus to control those slimy critters. Be on the lookout for Scale on plants – especially Crape Myrtles. Use All Seasons Oil to control. Fungus Issues? We have an organic fungicide called Serenade that can be used to prevent a wide variety of fungal diseases.
- Control fungal diseases on your roses with an application of Horticultural Corn Meal. Apply on the root zone and lightly scratch into the soil.
- Try Beneficial Nematodes to help control grubs, ants, fleas, and other ground-dwelling pests. There’s still time to apply Dry Molasses for fire ants. They hate it and it increases the microbial activity in the soil. Plus, before you know it you’ll have a large population of earthworms, which is a really good thing!
PRUNE: To maintain form only.
WATER: Keep automatic sprinklers off. Manually water after 2-3 weeks of little rainfall. Hand water new plants every couple days for two weeks to get them established.
MISCELLANEOUS: Be sure to maintain a 1″-2″ layer of mulch on your planting beds to conserve water and precious moisture. This is very important before summer’s heat arrives! Also, get outside with your family and friends!! Spring is the Best Time of Year in North Texas…so take full advantage!
PLANT: Heat loving season color! We have LOTS to choose from, such as Lantana, Zinnias, Vinca, Pentas, Begonias, and Purslane just to name a few. When choosing perennials remember that we are here to help you pick the “Right Plant for the Right Place.” Incorporate some tropical color out on your patio or pool deck to give your outdoor spaces some extra pizzazz with Tropical Hibiscus, Mandevilla, and Bougainvillea. Most tropical color blooms on new growth, so be sure to fertilize regularly throughout the summer with Colorscapes or ColorStar™ plant food to enhance blooming.
Container grown trees can be planted now, just be prepared to hand-water or use Treegator® bags on them to get them through the summer’s heat. It’s best to wait on planting balled and burlapped (B&B) trees until the fall.
PRUNE: As needed to control odd shaped growth and to maintain size on plants.
- Apply Colorscapes or ColorStar™ on annuals and perennials to keep them happily blooming. Don’t forget that we have bulk refill available for ColorStar™ which saves money when you need to re-purchase!
- Use SuperThrive® on newly planted plants, or any stressed plants and trees.
- Use Texas Tee 6-2-4 on your lawn again by the end of the month. May is the prime month for lawn grasses to grow. Make sure your lawn is fed properly to prepare it for the summer heat to come.
- Hand water newly planted plants to help them establish before the heat of summer kicks in. Remember a lot of our drought-tolerant plants have been grown with regular watering in their pots. You need to hand water them after planting for the first two to three weeks and gradually wean them off frequent watering as their root system establishes in your landscape. Once established (about a month) they can survive on less water.
- Consider converting your beds to drip irrigation to use water more efficiently.
- Because of the water restrictions in the past, we have learned which of our grasses and plants can survive and thrive on less. With our area continuously building and growing, water demand and usage will increase, and we will continue to see regional water restrictions in place. When summer’s heat returns, your established drought-tolerant and well-adapted plants (and your budget!) will love you.
- It is virtually impossible for us to give accurate pest advice over the phone. Bring in samples of problems in a baggie and we’ll advise you on choices for control. With insects, we encourage you to identify the insect first, then use an appropriate control for that bug.
- Check Crape Myrtles for scale on branches. The scale looks like small white fuzzy cotton pieces attached to the stems. Control with All Seasons Oil, which suffocates them. Once you see fungus it is hard to clear up the affected spots, but you can spray to prevent new foliage or other foliage from getting the problem.
- We carry an organic disease control product called Serenade Garden Disease Control. This product is safe for use on fruits, vegetables, and ornamentals. It can be used around people, pets, and wildlife. You can learn more about it through their website, www.serenadegarden.com. As always, we try to give you earth friendly options for pest control.
- Watch out for Bagworms on your evergreens this time of year when eggs hatch and the worms begin to move around and eat the needle leaves. Control the issue with B.T. (bacillus thuringiensis). We have this in a dry or liquid form.
