Frequently Asked Questions About Gardening

What can I do about weeds in my yard?

Weeds are likely poking through in the garden beds, even if you put down mulch or a landscape fabric liner to keep them at bay. Pull weeds from the root in vegetable or edible flower gardens, and dig up the roots if the weed snapped off without them. Be sure to get rid of weeds before the weeds' flowers dry out and and drop their seeds. 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 and heavy rubber gloves to ensure that the chemical 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 burnt spot with a good long drink. Just rehydrate those roots. It should perk up within the next week. On the other hand, the method for how to treat grass from dog urine isn't as simple. Grass damaged by pets must be removed, neutralized, and replaced in fresh soil with new sod, or patch and repair grass seed.

When's the best time to water my lawn?

Ideally, water early in the morning. The next best time is in the evening, when the sun is setting. Watering during the heat of the day means a lot of the moisture will evaporate. This applies to whatever you're growing: plants, vegetables, bushes, and grass. Whenever you water, 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 on the clock. Depending on your climate, grass type, and lawn health, you may also want to look into applying a lawn fertilizer.

When do I fertilize my flowers?

Once you've planted your flowers or plants, make sure they're hydrated and well-fed. Choose a synthetic or an organic 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 shrub fertilizer, fruit tree fertilizer, or a garden fertilizer blend. Only apply as often as directed on the packaging. More is not better here. Be sure to water immediately after, as directed, so the plants won't be burned by the fertilizer.

How can I create shade?

When you need a break from gardening in the sun, shelter beneath a patio umbrella or covered gazebo. If you have sturdy structures like a house or shed, make your own shade by attaching awnings and shade sails. 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 lounging in the sun when that water-cooled air is ready.

What do you carry for backyard entertaining?

Backyard entertaining is whatever you find enjoyable — it doesn't have to be a garden party. If you're focused on firing up the grill, make sure you know how to clean a grill afterward. Many people simply relax outdoors and chat all afternoon. Whichever path you take for bonding with friends, extend the fun into the evening with proper outdoor lighting. For best results, learn how to rid your yard of pesky mosquitos, too.

The Home Depot Garden Center at Portsmouth

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

Grow a Healthy Lawn
If you're concerned that your lawn has crispy and brown blades of grass, don't worry just yet. It's possible that you've got a cool season grass that goes dormant and turns brown in the summertime heat. If that's the case, it'll be an overall shade of brown, but not green with brown patches. See if the roots are alive by tugging on a blade of grass: If it comes right out, the grass is likely dead and will need to be replaced with new sod or grass seed. If the blade of grass doesn't come right out, it's dormant. That means it's growing and resting underground. Dormant grass should be watered deeply once or twice a week — if it doesn't rain — but don't fertilize it.

For warm-season grass that stays green in the summer, water a bit every few days and deeply once a week. The amount of water should add up to about an inch each week. Make sure not to overwater, and allow the lawn to dry out after heavy rains before you get out the hose or sprinkler again. Water your yard when the top two inches of soil is dry to the touch. You can test with your finger. This might happen quicker than you'd think during heat waves or drought. It's ok to let it grow a little taller this time of the year, as cutting it too short isn't healthy for this kind of lawn.

Watch Your Garden Thrive
Much of your garden's upkeep comes down to balancing water and sun, as outlined in these garden watering tips. You'll need both to keep your garden growing and spirits high with summer flowering. A general rule when watering flowers is to aim the water at the roots. A garden hose, drip irrigation system, or sprinkler 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 but recover once they dry off. Succulents are the exception to basic watering rules, so look up your specific types of succulents to optimize their care.

In addition to watering them regularly, monitor your plants' nutrient intake. Apply fertilizer as recommended. We've even got fertilizers to match the plants you're growing so they'll absorb the correct nutrients.

Grow Your Own Herbs
For fresh flavors to accent your homegrown produce, add herbs. They're generally low-maintenance. It's easy to learn how to grow herbs indoors, but you can raise herbs outdoors, too. If you grow herbs outdoors, stick to heat-loving herbs that'll endure the summer temperatures, and consider a hanging herb garden.

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

Trees as Natural Shade
Trees are a natural source of shade, and they can change the look of your yard. Whether you plant a few trees or a small forest, keep in mind this is a long-term commitment. Trees live many decades when they're healthy. Before you shop, read up on how to plant a tree, whether they're evergreens, deciduous tree 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 deep the taproots go, how far the roots extend outward, and the full-grown size of the trees you want. Trees will always find the easiest source of water, so be sure to plant them away from the water lines so they won't be damaged by moisture-seeking roots. Leave a safe distance from your home, as large trees can catch the wind if not properly pruned. If you've planned accordingly, found trees you love, and know the perfect places to put them, get planting. That way, you can enjoy the leaves rustling in the breeze and dappled shade sooner rather than later.
