Rose Fertilizer
Support repeat blooms, rich color, and healthy leaves with a liquid fertilizer made for roses. It provides consistent nutrition for healthy growth while keeping plant care straightforward.
Use it as part of your normal watering routine for simple, consistent feeding during active growth.
Why You'll Love It
- Bloom Support For roses that give one strong flush and then little repeat bloom.
- Healthy Foliage Supports healthy lower leaves on hybrid teas, floribundas and climbers.
- Steady Growth Directs energy toward flowering rather than leafy growth alone.

Liquid rose fertilizer with a 3-3.6-5.1 NPK plus kelp. Supports repeat blooms, rich color, and healthy leaves.
How to Use Rose Fertilizer
| Method | Amount | How Often |
|---|---|---|
| Watering can | 2 Tbs (30 mL) per gallon of water | Spring & summer: every 1–2 weeks |
| Watering can | Same dilution | Fall & winter: every 4 weeks |
| Hose end sprayer | Set dial to 1 oz (30 mL) setting | Spring & summer: every 1–2 weeks |
| Leaf misting (optional) | 1 tsp per quart (32 oz) of water | Every 1–2 weeks |
Mix into your normal watering — no separate feeding routine needed.
What's Inside
The 3-3.6-5.1 ratio is built for a plant that blooms in repeated flushes and burns through nutrients doing it. Phosphorus at 3.6% and potassium at 5.1% both outweigh nitrogen at 3%, keeping energy on flower production rather than leafy cane growth — the difference between a rose that reblooms all season and one that runs to foliage after the first flush. All of the nitrogen is nitrate nitrogen, the form roots absorb directly, so response is fast and burn risk stays low.
Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus calcium at 2.1% — unusually high, and what builds thick canes and firm petals that hold up through heat — magnesium (0.75%), iron, manganese, zinc, boron, and copper. Magnesium especially matters for roses, where a shortfall shows as yellowing between the veins on older leaves and weaker blooms above them.
Made For
Every rose type: hybrid teas, floribundas, grandifloras, climbers, ramblers, shrub and landscape roses, and miniatures — in beds, borders, and patio containers.
Problems It Solves
- Few blooms after a strong first flush
- Leafy, vigorous growth with little flowering
- Yellowing between the veins on lower leaves
- Weak canes and blooms that wilt fast in heat
FAQs
How often should I feed my roses?
Every 1–2 weeks during spring and summer while they're actively growing and blooming, and every 4 weeks in fall and winter. Diluting into your regular watering (2 Tbs per gallon) keeps nutrition steady — roses are heavy feeders and rebloom best on consistent feeding rather than occasional heavy doses.
My rose grew lots of leaves but few flowers — will this help?
That's usually nitrogen-heavy feeding pushing foliage at the expense of blooms. This formula runs phosphorus and potassium above nitrogen to shift energy toward flowering. Pair it with full sun and deadheading spent blooms, and you should see stronger repeat flushes through the season.
When should I stop feeding for winter?
Feed every 4 weeks through fall, then ease off as the plant goes dormant — pushing tender new growth late in the season leaves it vulnerable to cold. Resume the spring and summer schedule when new growth breaks in spring. In frost-free climates roses may bloom nearly year-round and can stay on the lighter fall schedule.
Will this burn my roses?
No — at the directed dilution, the formula is designed for regular use. All-nitrate nitrogen and low salt concentration make burn very unlikely. For newly planted or bare-root roses still establishing, start at half strength for the first two feedings.
Can I use it on climbers and container roses too?
Yes, at the same dilution. Container roses actually benefit most, since potting mix runs out of nutrients faster than garden soil. Use the watering can rate for pots and the hose end sprayer for beds and large climbers.
When will I see results?
New growth typically comes in greener within the first couple of weeks, and yellowing from magnesium shortfall corrects on new leaves. Bloom improvement follows the plant's own rhythm — consistently fed roses set noticeably heavier repeat flushes over the following weeks.
