What do pumpkins need?
Space - Pumpkin plant vines can grow over 20 feet long. Give plants plenty of space to grow. Use a tomato cage or small trellis for mini pumpkin varieties. For larger pumpkins, vines can grow on a fence. Make sure to support each pumpkin with a “sling” like a t-shirt or tied nylon stocking tied that is also tied to the fence.
Mounds - Make a small mound or hill and plant 3-5 pumpkin seeds per hill. Create a small basin around each planting to help keep the soil moist until seedlings appear.
Water – Water early in the morning. As the plants mature, water deeply and infrequently to a depth of 12 inches, allowing the soil to dry out slightly between watering.
Fertilizer – If desired, you can use a vegetable fertilizer labeled for pumpkins.
Thinning – If growing large pumpkins, select the best-looking fruit when it is small, and remove the others. This will send all the nutrients into that pumpkin so it can grow large.
Possible Pests
If you see any of these pests on your plants, visit the UC IPM Website tips on what to do.
Just for Fun
When pumpkins are small, carve your name or a cool design on the skin and it will become more apparent and look extra spooky as the pumpkin gets larger.

Beetles are the most plentiful of all insects on the planet, so it's understandable to get a few of them confused. Let's compare photos and other details about each of these beetles, and also mention the green June beetle, a beetle that is commonly mistaken for the Japanese beetle.
Japanese Beetles
Japanese beetles do not have an established population in California. The California Department of Food and Agriculture* (CDFA) maintains traps for detecting this pest throughout the state. When Japanese beetles are found in California, they are targeted for eradication (complete elimination). Read more about this invasive species on the UC IPM website at https://ipm.ucanr.edu/Invasive-and-Exotic-Pests/Japanese-Beetle/
Green Fruit Beetles
Green fruit beetles are a dull green color and much larger than Japanese beetles. You may notice them in late spring and summer as they zoom around your garden. Fortunately, they are rarely a pest. https://ipm.ucanr.edu/PMG/GARDEN/FRUIT/PESTS/grfruitbeetle.html
Rose Chafer Beetles
The rose chafer beetle resembles the hoplia beetle, however, this pest is not found in California. You can read more about these beetles on this informational page from University of Minnesota https://extension.umn.edu/yard-and-garden-insects/rose-chafers
Hoplia Beetles
Hoplia beetles are small, brown, and their undersides look like they've been dusted in gold. If you hold one in your hand, they will “play dead” and not move, making it easy to examine them.
You can read more details about managing hoplia beetles in the UC IPM Pest Notes: Hoplia Beetles.
*it's important that we help prevent invasive pests from taking hold in our communities and threatening agricultural crops. You can help by saying "yes" when trappers from the Agricultural Commissioner's Office ask if they can place traps in your landscape tree.

- Why are the leaves on my orange tree turning yellow?
It's common for citrus tree leaves to turn yellow in winter*. Fertilize to provide the tree with nutrients now, then watch as leaves green up in spring. Avoid fertilizing in fall, which encourages new growth favored by pest and can leave the tree susceptible to frost injury.
- How do I know if my oranges are ripe/when should I pick my oranges?
You don't have to pick all your oranges once they ripen. In fact, the best place to store oranges is on the tree, where they stay fresh! Pick as needed, unless temperatures below 28 F are predicted, then you'll want to harvest.
- What is this pest?
Scales and whiteflies suck plant juices and weaken the plant. Ants do two things:
- Protect pests from predators like ladybugs, parasitic wasps (very tiny wasps) and lacewings.
- “Harvest” honeydew (a sticky sugary substance excreted by these pests) for food, in a symbiotic relationship that does not include the gardener.
- Why are my oranges splitting?
The reason this happens is not well understood, although it's often related to changes in weather conditions. However, allowing the soil to dry out too much between irrigations is believed to result in increased splitting. Make sure your tree has a constant supply of moisture by watering monthly during the dry season.
- When should I prune my orange tree?
When pruning deciduous trees like peach, plum or cherry, after leaf drop, don't be tempted to prune citrus! Citrus trees are evergreen and require little if any pruning except to control size. If you'd like to keep a new citrus tree under 5 feet tall, you can carefully prune it in spring to manage the height. This way, you won't need a ladder to pick fruit again!
Avoid pruning in fall or winter, which encourages new growth favored by pests and can leave the tree susceptible to frost injury.
*if your tree leaves turn yellow and it's not winter, this may be a different problem.
