Should you cut brown leaves off plants?

Yes, but leave just a little bit of brown on each leaf to avoid stressing the plant. If it's brown and dry, then cut the whole leaf, but not too far from the main branch so that it will grow a new leaf. If it still green but just the tip is brown, then use a sharp pair of scissors to just trim the edges.

Should I cut the brown tips off my peace lily?

Follow the leave stem to the base of the plant and cut it off. You can also prune the leaves themselves should they get brown tips. To do this make an angled cut below the brown tip. This angled cut should keep the new tip from turning brown.

Do lilies need a lot of sunlight?

Planting and Care
Though lilies look like they'd be fussy plants, they are actually very easy to grow. They're not particular about soil type or pH and they grow well in full sun, part sun, dappled shade and even light shade. Even more than other bulbs, lilies demand well-drained soil.

Why do lily buds not open?

They prefer to be in full sun and in a well-drained, evenly moist soil. Overwatering causes soggy soil and leads to bulbs rotting. Unfortunately, your lilies will not grow new buds. If these buds don't open, cut them off and let the leaves and stem grow brown.

Can yellow leaves turn green again?

Diagnosis: If the leaves are turning yellow — almost jaundice-looking — and the center stalk is turning brown and getting a little soft, chances are you might be overwatering your plant.

Can you kill aphids with vinegar?

Get out a spray bottle and fill it 1/3 of the way with distilled white vinegar and the rest of the way with water. This will kill the aphids and larvae on contact. Place a square of aluminum foil around the base of plants affected by aphids. It is also good for the plants, as it brings them more natural sunlight.

Can you over water daylilies?

Do not over water however, as daylilies do not like to have their roots immersed in water for extended periods of time. Give the soil a chance to drain well before you water again. Fertilizer is important for healthy daylilies. Proper feeding will result in more and larger blooms and the plants will be more vigorous.

What is a good fertilizer for daylilies?

We typically use a balanced mix, such as 10-10-10, of a granular fertilizer each spring, broadcasting it over the top of the daylilies. Slow release fertilizer, liquid fertilizer, compost or well-rotted manure are all good choices as well.
