Frequently Asked Questions About Gardening

What can I do about weeds?

Weeds are likely poking through in the garden beds, even if you put down landscape fabric liner to keep them at bay. Pull weeds from the root in gardens you'll be eating from, and dig up the roots if the weed snapped off without them. Be sure to get them before they go to seed. If you'd like to treat weeds with weed killer, check that it's safe for bees, other pollinators, and pets — and wear a respirator mask and heavy-duty rubber gloves to ensure that it doesn't touch your skin or your lungs.

How do I fix yellow grass?

The solution for how to get burnt grass green again is simple: Fix the scorched spot with a long drink. Just rehydrate those roots. It should perk up within the next week. The method for how to treat grass from dog urine isn't as straightforward. Grass damaged by pets must be removed, neutralized, and replaced in fresh soil with new grass, sod, or patch and repair grass seed.

When's the best time to water my plants?

If you can water during the early morning or in the evening, that's ideal. Watering during the heat of the day means a lot of the moisture will evaporate. This applies to whatever you're growing: plants, trees, grass, and vegetables. Give all the plants a thorough drink, and don't skip it because it's not the best time. The plants still need hydration regardless of the time. Depending on your grass type, lawn's health, and climate, you may also want to look into applying a lawn fertilizer.

What are some tips to keep my plants healthy?

Once you've planted your flowers or plants, ensure they're well-fed and hydrated. Choose an organic or a synthetic fertilizer that fits your needs and give your garden a boost. You can even find one that's formulated for whatever you're growing, whether you need a fruit tree fertilizer, shrub fertilizer, or a general garden fertilizer blend. Only apply as often as directed on the packaging. Be sure to water immediately after, as directed, so the plants won't be burned by the fertilizer.

Do patio misters cool the air?

When you need a break from working in the yard, shelter beneath a patio umbrella or covered gazebo. Add awnings and shade sails to the shed or house to create shadowy spots to rest beneath. However, sometimes shade isn't enough because it's extremely humid out. That's when a patio mister or misting fan can help cool the air and make a stifling afternoon into a relaxing day. Go back to enjoying the sun when that water-cooled air is ready.

What do I need for backyard entertaining?

Backyard entertaining is whatever you'd like it to be — it doesn't have to be a garden party. Some focus on the grill or fire pit, while others concentrate on yard games. Many people simply relax outdoors and chat. However you bond with friends, you can extend the fun into the evening with proper outdoor lighting and a bug-free yard without pesky mosquitos.

As we stretch into summer, your garden and landscaping will weather more sun and heat than earlier in the season. That means you'll need to consider how to keep things cool with irrigation and shade. Just like we can get sunburned, grass can get scorched and trees can lose their leaves prematurely. Let us help. At the Garden Center in N Thornton, we've got what you need to make it through the hotter months.

Keep Your Lawn Tidy
As the weeks tick by, the grass seed or sod you planted will grow taller than what's ideal. Eventually, it'll need some maintenance to look manicured and fresh. Keep the lawn in check with a lawn mower and a string trimmer to knock down any tall grass around trees and hardscaping.

Trees and shrubs climb toward the sun and lose their shape over time. In the summer, they'll be growing fast, filled with buds and blooms before you know it. Prune them back to show off their verdant beauty with garden shears and hedge trimmers. It's best to leave major tree maintenance and tree topping to the pros, but you may want to use a pole saw for minor trims and a chainsaw to shape small trees and bushes.

Watch Your Garden Thrive
Water your garden between rainstorms to keep the summer flowering going. A general rule when watering flowers and plants is to aim the water at the roots. A sprinkler system, drip irrigation system, or garden hose can get the job done. You don't need to water or even mist the blooms themselves. Many flowers wilt and droop when they get wet, but they'll recover just fine once they dry. Succulents are an exception to basic watering rules, so look up your specific types of succulents to optimize their care.

In addition to watering them regularly, keep an eye on your plants' nutrient intake. Use fertilizer as recommended. We've even got fertilizers to match the plants you're growing so they'll get the right nutrients.

Grow Your Own Herbs
For savory flavors to accent your homegrown produce, try herb gardening. They grow easily in pots, both indoors and outdoors, and are generally low-maintenance. If you grow herbs outdoors, stick to heat-loving herbs that'll endure the summer temperatures, and consider a hanging herb garden.

Planting herbs in the ground can be tricky, as many of them — especially mint — are invasive and will take over your yard. So just keep them in small decorative pots on a sunny window sill, porch, or even in wall planters. Herbs also work well in a hydroponic garden, which means they don't grow in soil. Instead, they grow in a mix of sand, perlite, or rock chips.

Trees as Natural Shade
Trees are a stunning and natural source of shade, and they can change the look of your yard. Whether you plant a few trees as accents, a few more to bear fruit, or a whole mini-forest, remember this is a long-term commitment. When they're healthy, trees live many decades — and some for hundreds of years. Before you shop, read up on how to plant a tree, whether they're deciduous trees, evergreen saplings, or more mature trees.

A house framed by beautiful trees can seem picture-perfect, but research the specific trees you want before planting them. Think about how far the roots extend outward, the full-grown size of the trees you want, and how deep the taproots go. Plant your trees far from underground plumbing, as their strong roots will seek water and wend into piping to get it. As majestic as trees are, it's important to also consider how and where they'd fall if a major storm or disease weakened them. If you've planned accordingly, found trees you love, and know the ideal places to put them, get planting. That way, you can enjoy natural shade and the soothing sound of leaves rustling in the breeze sooner rather than later.
